Description

The present invention relates to a running method acquisition device for track and field runners used for running practice of track and field runners.

In track and field events such as short-distance running and long-distance running, as a device used for running practice of track and field runners, for example, a runner response exercise device that can change the moving speed of the movable surface following the run speed of the runner (Japanese Patent Laid-Open No. 9-84899) and a pitch calculation device (Japanese Patent Laid-Open No. 7-98388) capable of instructing a pitch for running an arbitrary distance with a target time have been proposed.
JP-A-9-84899 JP-A-7-98388

Recently, as a "lean running method" in athletics such as short-distance running and long-distance running, "stepping directly below", "not rotating the pelvis around the vertical line", "preventing vertical movement" were pointed out as issues ing.

The reason for “stepping down the landing foot” is to reduce the acceleration in the backward direction at the time of landing, that is, “to reduce the brake at the time of landing”.

The reason why the pelvis is not rotated around the vertical line is to speed up the action of the landing foot leaving the ground and stepping forward again. In other words, “do not rotate the pelvis around the vertical line” may be expressed as “run on two parallel straight lines instead of one straight line”.

“Preventing vertical movement” is to avoid exhaustion.

However, it is not easy for a runner to experience and learn these, and this running method cannot be learned by a conventionally known method or apparatus.

An object of the present invention is to provide a running method learning device for an athletics runner that allows a runner to easily learn “a lean running method”.

The present inventor dynamically analyzed “stepping right below”, “not rotating the pelvis around the vertical line”, and “preventing vertical movement” of “a lean running method” as follows. This will be described with reference to FIGS. ,

FIG. 1 is a side view showing the translational acceleration applied to the runner 101 immediately after landing. The translational acceleration is obtained by removing the acceleration component due to rotation. The umbilicus 142 is about 10 cm away from the center of rotation of the body, and the acceleration of the runner's umbilicus includes an acceleration component due to the rotation. FIG. 2 is a front view showing translation acceleration applied to the runner immediately after landing, and FIG. 3 is a plan view showing translation acceleration and angular velocity applied to the runner immediately after landing. 4 is a front view of the skeleton showing the runner's coordinate system, and FIG. 5 is a side view of the skeleton. The vertical line passing through the midpoint N (FIG. 4) of the line connecting the runner's left and right greater trochanters 112 is the Z-axis direction, the front-rear direction passing through the runner's umbilicus orthogonal to this is the Y-axis direction, and the Z-axis and Y-axis The left-right direction passing through the intersection and orthogonal to these is the X-axis direction, and the intersection of the XYZ axes is the origin O.

First, “reducing braking when landing” is to prevent deceleration. Since the deceleration is to apply a negative acceleration in the front-rear direction, the problem is attributed to “reducing the negative acceleration in the front-rear direction”. Immediately after landing, for example, as shown in FIGS. 1 and 3, a translational acceleration Y "is applied in the backward direction of the runner. The acceleration is proportional to the force applied to the runner, and the force applied to the runner is the muscular force generated by gravity and the landing foot. `` Stepping on '' is a word that instructs the component of the force generated by the landing foot to be only in the vertical direction, in other words, a word that instructs the translational acceleration component at landing to be only in the vertical direction. .

On the other hand, if the vehicle decelerates, acceleration is necessary to compensate for the speed, which appears in the action of “kicking backwards”. Therefore, the problem may be referred to as “reducing the positive acceleration in the front-rear direction”. When the runner gets on the cruise speed, the speed is only based on the speed of the foot, and acceleration is no longer necessary. Nonetheless, acceleration is necessary only because the brakes are applied. If acceleration is to be compensated for deceleration, it is better to reduce deceleration and keep the speed high by using the muscle strength used for acceleration to extend the foot. It is up to each individual runner to understand which expression of “reducing brake on landing” or “reducing kicking backward” is easy to understand.

Next, “do not rotate the pelvis around a vertical line” means “reduction in angular velocity of pelvic rotation”. When the time for each step is constant, if the rotation angle is large, the angular velocity obtained by dividing the rotation angle by time is also large, and the problem is attributed to “reducing angular velocity”. When the landing foot is in the center of the body in the left-right direction and the left and right landing feet are on the same line, the pelvis rotates around the vertical line. In a state where the angular velocity is reduced, the line 104 connecting the landing point of the left foot and the line 105 connecting the landing point of the right foot as shown in FIG.

However, if the distance between the two straight lines is excessively widened, left and right shaking will occur. Left and right swings should be avoided because they require struts and lead to exhaustion of physical strength. Left and right shaking means that the speed changes from left to right and from right to left, and prevention of left and right shaking is attributed to “reducing left and right acceleration”. “Reducing angular velocity” and “reducing left-right acceleration” are closely related issues.

The vertical movement converts the physical strength into potential energy by lifting the body, and is hardly recovered as energy at the time of landing, but rather uses the muscular strength again for shock buffering, leading to exhaustion of physical strength. Vertical movement is a change in speed from bottom to top and from top to bottom, and prevention of vertical movement is attributed to "reduction of acceleration in the vertical direction".

In this way, “stepping down directly” is “reducing brake when landing”, “reducing kicking backward”, and eventually “reducing positive acceleration in the front-rear direction”.

“Do not rotate the pelvis around the vertical line” is attributed to “reduction in angular velocity” or “reduction in lateral acceleration”.

Furthermore, “preventing vertical movement” is attributed to “reducing vertical acceleration”.

Therefore, the present inventor categorized “stepping straight down”, “not rotating the pelvis around the vertical line”, “preventing vertical movement”, “reducing the positive acceleration in the longitudinal direction”, “angular velocity” ”Reduction” or “Reduction in lateral acceleration” and “Reduction in vertical acceleration”, a target value in the desired axis (XYZ) direction is set in advance for translational acceleration or angular velocity, and It has been found out that the runner can easily learn the “lean running method” if the runner is informed of the result of each step compared with the measured value.

That is, the running method acquisition device for track and field runners of the present invention is such that the vertical line passing through the midpoint of the line connecting the runner's left and right trochanters is the Z-axis direction, and the runner's front-rear direction orthogonal to this is the Y-axis direction. Detecting means for detecting the acceleration in each XYZ axis direction and the angular velocity around the Z axis during traveling, with the left-right direction passing through the intersection of the Z-axis and the Y-axis being orthogonal to the X-axis direction, and detected by the detecting means The translational acceleration and angular velocity of the runner in each axis direction are calculated from the measured values and compared with the target value recorded in the storage means. If the measured value exceeds the target value, it is transmitted via the alarm transmission means. It is characterized by comprising control means for notifying the runner step by step and support means for assisting the runner to determine the target value in advance.

As shown in FIG. 6, the track learning apparatus for track and field runners according to the present invention (hereinafter simply referred to as “running method acquisition device”) includes detection means 124, control means 121, storage means 126, alarm transmission means 125, and support means 129. Consists of. The detection unit 124, the control unit 121, the storage unit 126, and the alarm transmission unit 125 may be the measurement alarm unit 120, and the support unit 129 may be provided separately from the measurement alarm unit 120.

The detection means 124 measures acceleration and angular velocity.

The control unit 121 includes a measurement control unit 122 and an alarm control unit 123. The measurement control unit 122 controls the detection unit 124 to calculate translational acceleration and angular velocity. The alarm control means 123 compares the measured translational acceleration and angular velocity with the target value of the runner, and sends an alarm signal to the alarm transmission means 125.

The storage means 126 includes a measurement value storage means 127 and a set value storage means 128. The measurement value storage means 127 records the measurement values, and the set value storage means 128 sets the runner's target values for the translational acceleration and angular velocity. Record the value in advance.

The alarm transmission means 125 sends an alarm signal (for example, an alarm sound) to the runner for notification.

The support unit 129 includes a unit conversion coefficient setting unit 130, a set value setting unit 131, and a target value examination support unit 132. The unit conversion coefficient setting unit 130 instructs the measurement control unit 122 to set a coefficient in an expression for converting the measurement value into translational acceleration and angular velocity and record it in the setting value storage unit 128. The setting value setting unit 131 sets the target value and the like. Is set and recorded in the set value storage means 128. The target value review support means 132 assists the runner to review and determine the target value.

[Detection means]

The detection means 124 has a plurality of acceleration and / or angular velocity detection means. The detection means may be composed of only the acceleration detection means, or may be composed of the acceleration detection means and the angular velocity detection means. A case where only the acceleration detection means is configured will be described as “detection system λ”, and a case where the acceleration detection means and the angular velocity detection means are configured will be described as “detection system θ”.

(Detection system λ)

An example of the arrangement of the acceleration detection means in the detection system λ is shown in FIGS. In FIG. 7, reference numeral 141 denotes a torso viewed from the direction of the head, and includes a navel 142 (coordinate values are shown in parentheses.
The runner wears the measurement alarm unit 120 on the abdomen, for example. In that case, the X axis is the left and right direction of the runner, the Y axis is the runner's front and rear direction, and the Z axis. Is the runner's vertical direction, and the origin O is the intersection of the Z axis passing through the midpoint N (FIG. 4) of the line segment connecting the runner's left and right greater trochanter 112 and the horizontal plane including the runner's navel 142. Two acceleration detecting means a and b are arranged at an equal distance L / 2 from the Y axis on a straight line in the XY plane parallel to the X axis and separated by a distance R from the X axis.

The origin 0 may generally be on the Z-axis passing through the midpoint N of the line connecting the runner's left and right greater trochanters 112, and the midpoint 145 of the line connecting the acceleration detecting means a and b is in the vicinity of the navel 142. Alternatively, it may be on the midpoint of both clavicles, on the sternum, or on the back lumbar vertebra 113 (FIGS. 5 and 7). When the middle point 145 is positioned on the back surface, the sign of R becomes negative. Each of the acceleration detection means a and b detects acceleration in the Y-axis direction, the X-axis direction, and the Z-axis direction.

When the acceleration detection means a and b can only detect biaxial directions, another acceleration detection means c is arranged near them as means for detecting the acceleration in the Z direction.

When the acceleration detection means a, b can only detect in one axis direction, two further acceleration detection means are arranged so that the coordinate values on the XY plane overlap with the acceleration detection means a, b.

The performance of the acceleration detecting means is preferably one having a resolution of about 0.005 [G] and a range of ± 5 [G].

(Principle of translational acceleration and angular velocity calculation by detection system λ)

In FIG. 7, when the coordinate system receives a translational acceleration and rotates slightly in the XY plane around the origin O, the X component of the acceleration obtained from the acceleration detecting means a placed in the positive direction of the X axis is x1 ″, Similarly, if the Y component is y1 ″, the X component of the acceleration measured by the acceleration detecting means b placed in the negative direction of the X axis is x2 ″, and the Y component is y2 ″, the translational acceleration X component X ″ and the translational acceleration Y The component Y ″ is as follows.
X ″ = (x1 ″ + x2 ″) / 2+ (y1 ″ −y2 ″) · R / L (Formula 1)
Y ″ = (y1 ″ + y2 ″) / 2− (x1 ″ −x2 ″) · R / L (Formula 2)
The Z component Z ″ of the translational acceleration is the acceleration z ″ in the Z-axis direction measured by the acceleration detecting means a, b, or c.

According to this means, the absolute value of the angular velocity around the Z axis can also be derived, and in principle, the following equation is obtained.
| Ψ ′ | = {(x2 ″ −x1 ″) / L} ^ 0.5 (Expression 3)
Here, ^ represents a power.

As can be seen from (Equation 1) and (Equation 2), when the acceleration detection means a and the acceleration detection means b are attached to the tips of both hip bones (on the vertical line passing through the greater trochanter), R becomes 0. If the outputs of the acceleration detecting means are averaged, there is an advantage that a translational acceleration can be obtained immediately.

Up to this point, the rotation is only in the XY plane and the rotation in the other planes is very small. However, if you want precision, arrange three or more three-axis acceleration detection means, etc. May be calculated in the same manner as described above.

(Detection system θ)

Examples of arrangement of the acceleration detection means and the angular velocity detection means in the detection system θ are shown in FIGS. Angular velocity for detecting rotation of a plane perpendicular to the Z axis by arranging one acceleration detection means d at a point on the Y axis at a distance R from the X axis, with the X, Y, and Z axes orthogonal to each other. The detection means e is arranged in the vicinity thereof. When the runner wears the measurement alarm unit 120 on the abdomen, for example, the X axis is the runner's left and right direction, the Y axis is the runner's front and back direction, the Z axis is the runner's vertical direction, and the origin O is typically the runner's left and right This is the intersection of the Z axis passing through the midpoint of the line segment connecting the trochanter 112 and the horizontal plane including the runner's navel 142. In FIG. 9, reference numeral 141 denotes a torso viewed from the head direction, and includes a navel 142 in this plane. The origin 0 may generally be on the Z axis passing through the midpoint of the line segment connecting the runner's left and right greater trochanters 112, and the acceleration detecting means d is on the midpoint of both clavicles, on the sternum, or on the back spine 113. But you can. When the midpoint acceleration detecting means d is positioned on the back surface, the sign of R becomes negative.

The acceleration detection means d detects acceleration in the Y direction, X direction, and Z direction. When the acceleration detection means d cannot detect in the three-axis directions, one or more acceleration detection means are arranged as close as possible to the acceleration detection means d as means for detecting the other two-axis acceleration. The performance of the angular velocity detecting means is preferably one having a resolution of about 0.017 [rad / sec] and a range of ± 14 [rad / sec].

(Principle of translational acceleration and angular velocity calculation by detection system θ)

In FIG. 9, when the coordinate system receives a translational acceleration and rotates slightly in the XY plane around the origin O, the X component of the acceleration obtained from the acceleration detecting means d is x1 ″ and the Y component is y1 ″. If the angular velocity measured by the angular velocity detecting means e is ψ ′ and its time derivative is ψ ″, the X component X ″ of the translational acceleration and the Y component Y ″ of the translational acceleration are as follows.
X ″ = x1 ″ + R · ψ ″ (Formula 4)
Y ″ = y1 ″ + R · ψ ′ ^ 2 (Formula 5)
The Z component Z ″ of the translational acceleration is the acceleration z ″ measured by the acceleration detecting means d or other acceleration detecting means arranged nearby. Here, ^ represents a power.

Up to this point, the rotation is only in the XY plane and the rotation in the other planes is very small. However, if the precision is required, three or more angular velocity detection means are arranged, and the other axes are also described above. The same calculation may be performed.

[Control means]

The control unit 121 includes, for example, the following five units as hardware.
1) CPU as a means of periodic measurement and calculation. It is preferable to use a CPU that can measure a set of measurements with a period of about 5 milliseconds.
2) ROM as software storage means. Software for controlling the measurement alarm unit 120 is stored in this ROM.
3) RAM as means for calculation work.
4) An AD converter or timer as means for converting the output signal of the acceleration detection means or angular velocity detection means into a digital signal. For example, when the output signal is voltage or current, an AD converter may be applied, and when the output signal is pulse width, a pulse width measurement timer may be applied.
5) Data storage control switch as measurement value recording instruction means.

(AD converter)

An AD converter that converts the output voltage or output current of the acceleration detection means and the angular velocity detection means into a digital signal that can be processed by the CPU linearly converts the input. A resolution corresponding to 0.005 [G] and a range corresponding to ± 5 [G] are desirable, but a resolution equivalent to 0.02 [G] may be used. An AD converter that receives a signal from the angular velocity detection means linearly converts the input. It is desirable to have a resolution corresponding to 0.017 [rad / sec] and a range corresponding to ± 14 [rad / sec]. When the input impedance of the AD converter is low or when the output from the detection means does not match the range of the AD converter, an operational amplifier is placed in the preceding stage to make the input impedance appear high for the acceleration detection means and the angular velocity detection means. Or range adjustment.

(Pulse width measurement timer)

When the outputs of the acceleration detection means and the angular velocity detection means are transmitted in pulse widths, they may be digitized by a pulse width measurement timer that counts, for example, the number of divided clock pulses of the CPU between the edges of the pulses. The pulse width measurement timer for receiving a signal from the acceleration detection means preferably has a resolution corresponding to 0.005 [G] and a range corresponding to ± 5 [G], but may have a resolution corresponding to 0.02 [G]. The pulse width measurement timer that receives a signal from the angular velocity detection means preferably has a resolution corresponding to 0.017 [rad / sec] and a range corresponding to ± 14 [rad / sec].

(Data storage control switch)

The data storage control switch is a measured value recording instruction means for instructing to start and stop recording of measured values. This is because when the storage means is small-scale, the recording area is not consumed with useless data, and it is also for giving a delimiter of data when comparatively analyzing several running methods. When the switch is turned on while recording is stopped, the CPU starts recording measured values. When the switch is turned on during recording, the CPU stops recording measurement values. Since the capacity of the storage means is limited, recording stops when the capacity is used up. When the recording is stopped, the length of the data is recorded in the index part of the storage means, thereby identifying the data delimiter. As the data storage control switch, for example, a push button switch is preferable because it does not cause difficulty in operability during travel, and is preferably large and excellent in click feeling.

The control means 121 includes a measurement control means 122 and an alarm control means 123 as software. The measurement control means 122 includes 1) periodic measurement control means, 2) unit conversion means, and 3) translational acceleration and angular velocity. It is comprised from three means of the means to calculate.

"Regular measurement control means"

The control means for periodically performing the measurement includes, for example, a means for counting the number of frequency-divided pulses of the clock pulse of the CPU, generating a signal every time the clock pulse reaches a certain number, and restarting the count from 0. Called a timer. If the voltage or current is measured according to the signal of the periodic timer, the AD converter may be activated. If the pulse width is measured, the acceleration detecting means and the angular velocity detecting means are activated according to the signal, and the pulse The pulse width may be measured with a width measurement timer.

"Unit conversion means"

A value obtained by digitizing the output of the acceleration detecting means with an AD converter or the like is converted into acceleration (unit G) by the following equation.
Acceleration = 2 / (A−B) · Digital value−2 · (A / (A−B)) + 1 (Formula 6)
Here, A and B are coefficients stored in the set value storage means 128 and are set as follows. A is a value obtained by giving an acceleration of +1 [G] by directing the positive direction of the axis of the acceleration detecting means directly upward, and measuring and digitizing the acceleration. B is also a value obtained by measuring and digitizing an acceleration of -1 [G] by directing the positive direction of the axis directly below. There is a coefficient for each axis of each acceleration detecting means, and each acceleration is calculated.

The configuration of the detection means is “detection system λ” as follows.
1) Calculate the acceleration x1 ″ from the X-axis coefficients A and B of the acceleration detection means a and the digital value 2) Calculate the acceleration y1 ″ from the Y-axis coefficients A and B of the acceleration detection means a and the digital value 3) Acceleration x2 ″ is calculated from the X-axis coefficients A and B of the acceleration detection means b and the digital value 4) The acceleration y2 ″ is calculated from the Y-axis coefficients A and B of the acceleration detection means b and the digital value 5) Acceleration detection Calculate the acceleration z ″ from the Z-axis coefficients A and B of the means a, b or c and the digital value.

The configuration of the detection means is “detection system θ” as follows.
1) Calculate acceleration x1 ″ from the X-axis coefficients A and B of the acceleration detection means d and the digital value 2) Calculate acceleration y1 ″ from the Y-axis coefficients A and B of the acceleration detection means d and the digital value 3) Acceleration z ″ is calculated from the Z-axis coefficients A and B of the acceleration detection means d and the digital value.

A value obtained by digitizing the output of the angular velocity detection means with an AD converter or the like is also converted into an angular velocity of unit rad / sec by the same equation (7).
Angular velocity = 2nπ {2 / (C−D) · digital value−2 · C / (C−D) +1} (Expression 7)
In this case, C and D are measured by rotating the measurement alarm unit counterclockwise and clockwise about the axis (unless precise is required, only the Z axis) at a speed of n times / second. The digitized value. n is suitably from 3 to 4, but a linear equation may be determined by trying a large number of revolutions and applying the least squares method.

"Means for calculating translational acceleration and angular velocity"

The translational acceleration and the angular velocity are calculated by software recorded in the CPU and software storage means. The contents of the software are as shown in the above formulas 1-7.

[Storage means]

The storage means 126 (FIG. 6) needs to be recordable even when the power is turned off and can be erased electrically and reused. For example, an EEPROM can be used. Among these, a serial EEPROM that requires a small mounting area is preferable. The capacity is preferably 64 KBYTE or more. If a large capacity recording medium is required, a flash memory may be used.

The storage means 126 is composed of two pieces of software: 1) measured value storage means 127 and 2) set value storage means 128.

"Measurement value storage means"

The measurement value measured and detected by the detection unit 124 is recorded in the measurement value storage unit 127. In order for the runner to know his / her translational acceleration data and angular velocity data as numerical information, it is necessary to record measured values, which is a means for that purpose.

The content to be recorded may be in a format that can reproduce the value compared with the target value, may be raw data received from the detection system λ or the detection system θ, may be a value obtained by unit conversion, a calculated translational acceleration, Angular velocity may be used. You may record the average value during a recording period by making the multiple of a measurement period into a recording period. In this case, however, the target value excess determination is also made for the average value. The advantage of using the average value is to reduce the influence of mixing of exceptional values, to save recording capacity, and to provide rationality in saving recording capacity by reflecting data fluctuations between recording periods.

`` Set value storage means ''

The set value storage unit 128 of the storage unit 126 records the set values set by the unit conversion coefficient setting unit 130 and the set value setting unit 131 of the support unit 129 described later. The set values recorded in the set value storage unit 128 are, for example, 1) measurement cycle, 2) recording cycle, 3) alarm assignment (type of alarm to be assigned to the alarm transmission unit 125), and 4) a reference for alarm notification. Target value, 5) Distance r (distance between the Z axis passing through the midpoint of the line segment connecting the left and right greater trochanters and the measurement alarm unit, for example, the distance between the origin O and the navel 142 in FIG. 7), distances Ha, Hb, 6) There are unit conversion coefficients A, B, C, and D (unit conversion coefficients are coefficients for converting a voltage value converted into a digital signal or a pulse width time into units of acceleration and angular velocity).

[Alarm transmission means]

The translational acceleration and the angular velocity are compared with a preset target value by the alarm control means 123 of the control means 121. For example, if the target value is exceeded, an alarm signal is immediately sent to the runner through the alarm transmission means 125. The Examples of alarm transmission means include acoustic transmission means, vibration transmission means, light transmission means, image display means, and the like, and a combination thereof may be used. A plurality of types of alarm signals may be transmitted by separate transmission means.

Examples of the sound transmission means include stereo earphones, speakers, and buzzers. When using stereo earphones, different types of alarms can be transmitted to the left and right ears.

As the vibration transmitting means, for example, there is a vibration motor. Since vibration is transmitted to the runner with skin sensation, all kinds of alarms can be transmitted by a plurality of vibration generating means.

As the light transmission means, for example, there is a light emitting diode. For example, if it is attached to glasses, separate alarms can be transmitted to the left and right eyes.

As the image display means, for example, a liquid crystal display device is mounted on one eye of glasses, and all types of alarms can be transmitted by letters or figures.

<Alarm control means>

The alarm control unit 123 compares the translational acceleration and the angular velocity with a target value set in advance. For example, when the target value is exceeded, an alarm signal is immediately transmitted to the runner through the alarm transmission unit 125. The alarm control means further comprises the following three means (software), 1) alarm allocation determination means, 2) target value excess determination means, and 3) divergence degree display means.

"Alarm assignment judgment means"

In order to make the alarm transmission means correspond to the alarm type, a means that can be selectively set in the measurement alarm section is provided in advance. One of the options is not to correspond to the alarm type. This means of selection and setting is called alarm assignment. The means to control the target value to be exceeded only for the type of alarm selected by the runner and to issue the alarm only for the specified alarm transmission means is assigned to the alarm. This is called determination means.

There are two types of alarms, for example, as follows: major numbers represented by numbers with single parentheses and subdivisions represented by letters with single parentheses.
1) Longitudinal translation acceleration target value excess alarm a) Longitudinal translation acceleration positive target value excess alarm b) Longitudinal translation acceleration negative target value excess alarm 2) Left and right translation acceleration target value excess alarm a) Left and right translation acceleration B) Horizontal translation acceleration positive target value excess alarm c) Horizontal translation acceleration negative target value excess alarm 3) Vertical translation acceleration target value excess alarm a) Vertical translation acceleration positive target value excess alarm 4 ) Angular velocity target value excess alarm a) Angular velocity absolute value target value excess alarm

"Target value excess judgment means"

(Means for determining whether the translational acceleration in the longitudinal direction exceeds the target value)

The target value excess warning for the longitudinal translational acceleration is subdivided into a longitudinal translational acceleration positive target value excess alarm and a longitudinal translational acceleration negative target value excess alarm, and the target value excess determination means corresponding to these is as follows.

The longitudinal translational acceleration positive target value excess warning corresponds to a means for comparing the longitudinal translational acceleration with a positive target value of the longitudinal translational acceleration preset by the runner, and when this means is used, the longitudinal translational acceleration is If it is larger than the target value, the CPU issues an alarm signal to the alarm transmission means assigned to the forward / backward translational acceleration positive target value excess alarm.

The forward / backward translational acceleration negative target value excess alarm corresponds to a means for comparing the forward / backward translational acceleration with the negative target value of the longitudinal translational acceleration preset by the runner. If it is smaller than the target value, the CPU issues an alarm signal to the alarm transmission means assigned to the forward / backward translational acceleration negative target value excess alarm.

(Right-side translation acceleration target value excess judgment means)

The horizontal translation acceleration target value excess alarm is subdivided into the horizontal translation acceleration absolute value target value excess alarm, the lateral translation acceleration positive target value excess alarm, and the lateral translation acceleration negative target value excess alarm. The value excess judging means is as follows. Since it can be expected that the translational acceleration in the left / right direction is almost a positive / negative symmetrical value, only the alarm for exceeding the absolute value of the lateral translation acceleration target value may be implemented. The negative target value excess warning may be implemented when special enhancement is desired.

The left-right translational acceleration absolute value target value excess alarm corresponds to a means for comparing the absolute value of the lateral translational acceleration with the target value of the lateral translational acceleration set in advance by the runner. If the absolute value of the acceleration is larger than the target value, the CPU issues an alarm signal to the alarm transmission means assigned to the left-right translational acceleration absolute value target value excess alarm.

The left-right translational acceleration positive target value excess warning corresponds to a means for comparing the left-right translational acceleration with the positive target value of the left-right translational acceleration preset by the runner. If it is larger than the target value, the CPU issues a warning signal to the warning transmission means assigned to the right / left translational acceleration positive target value excess warning.

The left-right translational acceleration negative target value excess alarm corresponds to means for comparing the left-right translational acceleration with the negative target value of the left-right translational acceleration preset by the runner. If it is smaller than the target value, the CPU issues an alarm signal to the alarm transmission means assigned to the left-right translational acceleration negative target value excess alarm.

(Target for exceeding the target value of translational acceleration in the vertical direction)

The vertical translation acceleration target value excess warning is a vertical translation acceleration positive target value excess warning, and corresponds to means for comparing the vertical translation acceleration with the positive target value of the vertical translation acceleration preset by the runner. When this means is operated, if the vertical translation acceleration is larger than the target value, the CPU issues an alarm signal to the alarm transmission means assigned to the vertical translation acceleration positive target value excess alarm.

(Angular velocity target value excess judgment means)

The angular velocity target value excess alarm is an absolute angular velocity target value excess warning that corresponds to a means for comparing the absolute value of the angular speed with the target value of the angular speed preset by the runner. If the value is larger than the target value, the CPU issues an alarm signal to the alarm transmission means assigned to the angular velocity absolute value target value excess alarm.

(Example of alarm assignment)

For example, when the alarm transmission means is a stereo earphone and all of the above-mentioned alarm types can be allocated, the alarm allocation options are as follows: one of 1) to 8), and 9) to 16) One can be selected from the total.
1) Assign a forward / backward translation acceleration positive target value excess alarm to the left ear of the stereo earphone 2) Assign a forward / backward translation acceleration negative target value excess alarm to the left ear of the stereo earphone 3) Left / right translation acceleration to the left ear of the stereo earphone Assign absolute value target value excess alarm 4) Assign left and right translation acceleration positive target value excess alarm to left ear of stereo earphone 5) Assign left and right translation acceleration negative target value excess alarm to left ear of stereo earphone 6) Stereo earphone 7) Allocation of absolute acceleration target value excess alarm to the left ear of stereo earphone 8) No alarm is assigned to left ear of stereo earphone 9) Right ear of stereo earphone 10) Assign the forward / backward translational acceleration positive target value excess alarm to the right ear of the stereo earphone. 11) Allocate a negative translational acceleration target value alarm to the right ear of the stereo earphone. 12) Assign an absolute target absolute value of the lateral acceleration acceleration to the right ear of the stereo earphone. ) Assign left and right translational acceleration negative target value excess alarm to right ear of stereo earphone 14) Assign vertical translation acceleration target value excess alarm to right ear of stereo earphone 15) Exceed absolute value of angular velocity target value to right ear of stereo earphone Assign an alarm 16) Do not assign an alarm to the right ear of a stereo earphone.

For example, when 2) and 14) are selected, it is determined that the target negative value is exceeded for the longitudinal negative translational acceleration and the vertical translational acceleration, and if the determination result is true, an alarm is issued. With respect to the direction positive translation acceleration, the left-right translation acceleration, and the angular velocity, it is not determined that the target value has been exceeded, and no alarm is issued. If the selected items are, for example, 8) and 16), the determination that the target value has not been exceeded is not performed at all, and no alarm is issued.

"Difference display means"

The divergence degree display means is means for displaying the difference between the translational acceleration and the angular velocity and the respective target values, that is, the degree of divergence. The runner can experience how far the target value is deviated by means of the deviation degree display means. The divergence degree display means when using an acoustic transmission means, a vibration transmission means, a light transmission means, and an image display means as the alarm transmission means will be described.

(Separation degree display means in sound transmission means)

When the alarm transmission means is an acoustic transmission means, for example, there is a method using frequency. In that case, there is a method of emitting a higher frequency or a method of emitting a lower frequency as the difference is larger. In addition, there is a method based on the strength of the sound, and in that case, there is a method of emitting a stronger sound as the difference is larger. Further, the frequency method and the strength method may be combined.

For example, the frequency-based method counts the number of frequency-divided pulses of the CPU clock pulse, and every time this reaches a certain number, the count is calculated and the output terminal is switched ON / OFF. By doing so, it is possible to generate treble and by increasing it, bass can be generated. For example, there is a method of controlling the amplification factor of an amplifier connected to a sound source by a digital / analog converter (DA converter). Alternatively, a pulse train having a variable duty ratio may be sent to the integrating circuit, and the magnitude of the integrated value may be controlled by the duty ratio to replace the DA converter.

(Deviation degree display means in vibration transmission means)

When the alarm transmission means is a vibration transmission means, the degree of deviation may be expressed by, for example, the intensity of vibration and the frequency of vibration as in the case of the acoustic transmission means.

(Deviation degree display means in light transmission means)

When the alarm transmission means is a light transmission means, the degree of deviation may be expressed by, for example, a method based on the intensity of the radiation intensity of the light source, and the realization means is the same as the generation of the intensity of sound. Alternatively, when a light source having three colors of red, blue and yellow is used, color expression can be achieved by changing the radiant intensity of each color, and the degree of deviation may be expressed by colors from blue to red. It is the same as the occurrence of strength.

(Deviation degree display means in image display means)

When the alarm transmission means is an image display means, the degree of divergence may be expressed by, for example, a numeral, a graph, a table intention form, or a combination thereof.

[Support means]

For the support means 129 of FIG. 6, for example, a notebook or desktop personal computer can be used as hardware.

When a personal computer is used as the support means, the support means 129 includes, for example, the following seven means as hardware.
1) A CPU as means for editing transmission / reception information.
2) RAM as program loading means and calculation work means.
3) A mass storage device such as a hard disk drive as software storage means. Stores software for editing transmission / reception information.
4) A screen display device such as a cathode ray tube or a liquid crystal display as means for displaying measured values in numerical values and graphs.
5) An input device such as a keyboard or a mouse as input means for setting values and instructions.
6) A communication device represented by RS-232C as means for communicating with the measurement alarm unit.
7) A printing apparatus as means for displaying measured values as numerical values and graphs on a paper medium.

When a separate personal computer is used as the support unit 129, the part excluding the support unit 129, that is, the measurement alarm unit 120, and the support unit 129 are connected via a communication unit. Therefore, communication means are arranged in the measurement alarm unit 120 and the support means 129, respectively. As a communication means, it consists of RS-232C level converter and RS-232C communication connector, for example. The RS-232C level converter is an integrated circuit that adjusts the voltage of the communication line to the standard, and the RS-232C communication connector is a connector for connecting a communication cable. While the storage means is small, RS-232C may be used, but a higher speed USB or Ethernet (registered trademark) may be used. The personal computer is connected by a communication cable, but is not connected when the runner wears the measurement alarm unit 120 and travels.

The medium connecting the measurement alarm unit 120 and the support unit 129 may be not only a wired communication cable but also a radio wave such as an electromagnetic wave and an infrared ray. In that case, a wireless transmission / reception unit and a modulation / demodulation unit serve as a substitute for the communication cable. . The modulation method includes, for example, a frequency modulation method, but may be an amplitude modulation method or a phase modulation method. When connecting wirelessly, it is wirelessly connected to the transmission / reception means attached to the support means side.

Note that the measurement alarm unit 120 and a personal computer which is a separate support means 129 may be always connected wirelessly. In this case, while the runner is running with the measurement alarm unit attached to the body, the instructor draws a desired graph etc. on the screen of the support means based on the measurement data sent to the support means as needed. Set a target value and send a new warning to the running runner in the measurement alarm section, or set a new target value and give a voice to the runner who is running so that the driving form will approach it An instruction may be issued. In addition, the support means and a display device such as a large screen in the running stadium are connected by wire or wireless to display graphs and target values on a large screen, etc. You may be able to do it.

<When the measurement alarm section is self-contained>

The support means 129 may be built in the measurement alarm unit 120 and may be self-contained. In this case, the support means includes the following five means, for example.
1) CPU as target value examination support means. It is desirable to have a performance capable of executing floating point arithmetic more than 1 million times per second.
2) ROM as software storage means. Target value review support software is stored in this ROM.
3) RAM as means for calculation work. It is desirable that it is 1 MBYTE or more.
4) Screen display means for displaying measured values as numerical values and graphs. For example, there is a liquid crystal graphic display. Those capable of displaying at least 200 × 200 dots are preferable.
5) Setting value and instruction input means. For example, there is a numeric key input device, and it is preferable that there are keys for assigning functions such as determination, cancellation, and cursor movement in addition to numeric keys.
The above 1) to 3) may be shared with the control means 121.

Regardless of whether it is a non-self-contained type or a self-contained type, the support means 129 has 1) unit conversion coefficient setting means 130, 2) set value setting means 131, 3) target value examination support means as software. 132 consists of three.

"Unit conversion coefficient setting method"

The unit conversion coefficient setting means 130 is an initial setting means performed at the time of manufacture, and the coefficients A, B, and (Expression 7) of (Expression 6) for converting measured values digitized by an AD converter or the like into units of acceleration and angular velocity. Software means for setting C and D. The unit conversion coefficient is set as follows, and the set value is displayed on the display means.

The unit conversion coefficients of acceleration are A and B in (Expression 6). When the acceleration detection means a and b are triaxial acceleration detection means, the coefficients A and B are relative to the X, Y and Z axes of the acceleration detection means a and b, and the acceleration detection means a and b are biaxial acceleration. In the case of detecting means, the X and Y axes of the acceleration detecting means a and b and the Z axis of the acceleration detecting means c are set. Each unit conversion coefficient is set as follows.

In the setting of A on the X axis, the right side (X axis positive direction) of the acceleration detection means a and b is directed directly upward, an acceleration of +1 [G] is given to the X axis, and then “+ 1G of the X axis is measured. When the control means 121 is instructed, the control means measures and digitizes the X-axis acceleration of the acceleration detection means a and b, and digitizes each value as A for each of the X-axis of the acceleration detection means a and b. Record.
The instruction “Measure + 1G on the X axis” is issued by the built-in input means if the support means is self-contained hardware.
If the support means is a separate personal computer, it is input by an input means such as a keyboard or a mouse of the personal computer, and an instruction is sent to the control means via the communication means. The method of giving instructions is the same in the settings described below.

In the setting of B on the X axis, the acceleration detection means a, b are directed to the left side (the negative direction of the X axis), and an acceleration of −1 [G] is applied to the X axis. Is given to the control means, the control means measures and digitizes the X-axis acceleration of the acceleration detection means a and b, and converts each value to B of each of the X-axis of the acceleration detection means a and b. Record as.

In the setting of A on the Y axis, the front side (Y axis positive direction) of the acceleration detection means a and b is directed directly upward, an acceleration of +1 [G] is applied to the Y axis, and then “+1 G of Y axis is measured. When the control means is instructed to the control means, the control means measures and digitizes the acceleration of the acceleration detection means a, b and records each value as A for each of the Y axes of the acceleration detection means a, b. To do.

In the setting of B on the Y axis, the rear side of the acceleration detection means a and b (the negative direction of the Y axis) is directed directly upward, an acceleration of −1 [G] is applied to the Y axis, When an instruction “Measure 1G” is given to the control means, the control means measures and digitizes the acceleration on the Y axis of the acceleration detection means a and b, and digitizes each value for each of the Y axes of the acceleration detection means a and b. Record as B.

In the setting of A on the Z axis, the upper side of the acceleration detection means a, b or c (positive direction of the Z axis) is directed directly upward, an acceleration of +1 [G] is given to the Z axis, When the control means is instructed to measure, the control means measures the Z-axis acceleration, digitizes it, and records it as A on the Z-axis.

In the setting of B on the Z axis, the acceleration detection means a, b or c is directed downward (Z-axis negative direction) directly above to give an acceleration of −1 [G] to the Z axis. When an instruction “Measure -1G” is given to the control means, the control means measures the Z-axis acceleration, digitizes it, and records it as B on the Z-axis.

When the angular velocity detecting means is mounted, the unit conversion coefficients of the angular velocity are C and D in (Equation 7), and are set as follows only for the Z axis unless precise is obtained.

In setting C, the upper side of the angular velocity detecting means is directed right above and placed on a rotating device such as a potter's wheel, etc., and the control means is given an instruction to “measure C on the Z axis” and the wheel is turned counterclockwise. Rotate around n times / second. The control means measures and digitizes the angular velocity after a certain time has elapsed, and records it as a value of C corresponding to 2nπ [rad / sec].

In setting D, the upper side of the angular velocity detecting means is placed on the top of the wheel, and the control means is given an instruction “measure D on the Z axis” and the wheel is turned n times / second clockwise. Rotate at a speed of. The control means measures and digitizes the angular velocity after a certain period of time, and records it as a value of D corresponding to −2nπ [rad / sec].
n is suitably from 3 to 4, but a linear equation may be determined by trying a large number of revolutions and applying the least squares method.

`` Setting value setting means ''

The setting value setting means 131 of the support means 129 is composed of 1) a setting value inquiry means and 2) a setting value receiving means as software.

The “setting value inquiry means” is means for taking out and editing the setting values already set in the storage means in accordance with the operator's inquiry request, displaying them on the display means, and notifying the operator of the setting contents.

The “setting value receiving unit” is a unit that receives the setting value input by the operator, checks its validity, and stores it in the setting value storage unit.

If the support means is self-contained hardware, the inquiry request or set value by the operator is input by the input means incorporated in the measurement alarm unit, and if the support means is a separate personal computer, the keyboard or mouse of the personal computer And is sent to the control unit of the measurement alarm unit via the communication unit.

The processing result of the inquiry request or the setting value setting result is displayed on the display means built in the measurement alarm unit if the support means is self-contained hardware, and personalized via the communication means if the support means is a personal computer. It is displayed on the display means (monitor) of the computer.

The setting values will be described below excluding the unit conversion coefficient.

The “measurement cycle” is a periodic measurement cycle. The device constant may be excluded from the changeable setting value. When fixing, it is desirable to be about 5 milliseconds. 5 milliseconds is the time required to travel about 5 cm for short distance running and about 3 cm for medium and long distance running.

The “recording cycle” is a cycle for recording in the storage means and is a multiple of the measurement cycle. When the average value of the measured values during the recording period is recorded, a value equal to or more than twice the measuring period is set. If the measured value is recorded as it is, the same value as the measuring period is set. It is desirable to limit the recording period to 25 milliseconds or less.

“Alarm assignment” is a type of alarm assigned to the alarm transmission means.

The “target value” is a value that serves as a reference for alarm generation, and is a value derived by a target value review support means described later.

The “distance r” between the Z axis passing through the midpoint of the line segment connecting the left and right greater trochanters and the measurement alarm unit is the distance between the origin O and the navel 142 in FIG. 7 or FIG. As a measuring method, for example, there is a method in which a runner stands sideways, marks the position of the greater trochanter 112 (FIG. 7) and the position of the navel 142 on the wall, and measures the horizontal distance between the two marks with a ruler.

When the measurement alarm unit is attached to other than the umbilicus, for example, in the case of the sternum, the position of the sternum is marked on the wall, and the horizontal distance from the greater trochanter is measured with a ruler. 7 and FIG. 9), the position of the lumbar vertebra is marked on the wall, and the horizontal distance from the greater trochanter is measured with a ruler. However, r is set as a negative value when the measurement alarm is attached to the back of the body. r is a value for obtaining R (Y coordinate of 145 when FIG. 7 is taken as an example).

The measurement alarm unit 120 sets the distance Ha (FIGS. 7 and 9) from the front surface of the housing to the acceleration detection means and the distance Hb (FIGS. 7 and 9) from the back surface of the housing to the acceleration detection means as positive device constants. Built in as When r is positive, R = r + Hb, and when r is negative, R = r−Ha.

"Target value examination support means"

The target value examination support means is a means for the runner to know his / her translational acceleration and angular velocity as numerical information and to assist in the examination of the target value achievable by each person. The target value examination support means displays the frequency distribution by the following processing process, and displays the result of the target value.

The target value examination support means acquires the measurement value from the storage means.

The target value examination support means divides the data sequence of translational acceleration and angular velocity arranged in time series into a data sequence for each step. At this time, a time series graph may be created by using separately created software. For example, if the vertical axis represents translation acceleration and angular velocity, the horizontal axis represents time, and a time series graph showing the data sequence of translation acceleration and angular velocity in time series is drawn, the vertical translation acceleration Z " A large peak is shown, and the midpoint of adjacent peaks of Z ″ is taken as a step break, and the data row is divided into data rows for each step. Since the data sequence sandwiching the peak records the state from landing to the air jump, it is appropriate to place the peak at the center of the data sequence for one step. The time series graph creation software may be incorporated in the target value examination support means in advance.

The target value examination support means picks up the next value from the data sequence for each step.
a) Maximum value for each step of translational acceleration in the longitudinal direction b) Minimum value for each step of translational acceleration in the longitudinal direction c) Maximum value of the absolute value of translational acceleration in the lateral direction d) Maximum value of the translational acceleration in the lateral direction Maximum value for each step e) Minimum value for each step of translational acceleration in the left-right direction f) Maximum value for each step of translational acceleration in the vertical direction g) Maximum value for each step of absolute value of angular velocity For example, If the code-specific target value excess warning is not required, the operation d) e) may not be performed.

The target value examination support means displays a frequency distribution graph in which the vertical axis indicates the frequency and the horizontal axis indicates the translational acceleration or the angular velocity, with the maximum value or the minimum value picked up from the data sequence for each step. Examples of the frequency distribution graph to be displayed include the following types.
a) Frequency distribution graph of maximum value for each step of translational acceleration in the longitudinal direction
b) Frequency distribution graph of minimum value for each step of translational acceleration in the longitudinal direction
c) Frequency distribution graph of maximum value for each step in absolute value of translational acceleration in the left-right direction
d) Frequency distribution graph of maximum value for each step of translational acceleration in the left-right direction
e) Frequency distribution graph of minimum value for each step of translational acceleration in the horizontal direction
f) Maximum frequency distribution graph for each step in the vertical translational acceleration
g) Frequency distribution graph of the maximum value of the absolute value of the angular velocity for each step.

The operator determines and inputs a target value as appropriate while looking at the frequency distribution graph. As an input method, a number may be key-input, or a cursor line indicating a target value may be moved on the graph. As the target value to be determined, for example, the following seven values can be considered according to the frequency distribution graph.
a) Positive translational acceleration target value b) Negative translational acceleration target value c) Horizontal translational acceleration absolute target value d) Horizontal translational acceleration positive target value e) Horizontal translational acceleration negative target value f) Vertical direction Translational acceleration target value g) Angular velocity absolute value target value

In determining the target value, the value is such that the frequency is 1 or more in both the range smaller than the target value and the larger range. That is, the target value is determined so that the ratio of alerting (reporting rate) is greater than 0% and less than 100%. (If the target value is such that the alarm alert rate is 0%, no alarm will be issued, and if the target value is set so that the alarm alert rate is 100%, all steps will be taken. Alarm will be issued).
Therefore, when the target value is set as described above, when the target value is exceeded, an alarm is usually issued once per step (in some cases, multiple times) (for one step at which the target value is achieved) Alarm will not be issued). Therefore, the runner can think about the difference in the running method between the one step when the warning is issued and the one step when the warning is not issued, and the running method can be corrected and confirmed every step.

According to the running method learning device of the present invention, the measured value and the target value are compared, and when the measured value exceeds the target value, the runner is notified step by step as an alarm. Considering the difference between one step that was made and one step that was not reported, it is possible to correct and confirm the running method for each step, so that the running method can be learned more appropriately and quickly.

According to the running method learning apparatus of the present invention, since the target value is clear, if the target value is selected properly, it is possible to learn the running method alone without a regular teacher.

According to the running method learning apparatus of the present invention, the results can be displayed on the screen as numerical values or graphs, and the target value can be visually examined and set, so that the runner can be convincing and the running method can be learned theoretically.

According to the driving method learning device of the present invention, not only the past driving data of oneself but also the driving data of an excellent person obtained by using this device is input and stored, so that the driving method of an excellent person can be obtained. Can be compared.

According to the running method learning device of the present invention, the instructor can display the running data of a plurality of players on the screen, etc., and can compare and examine the running methods of excellent players and those of other players, Quantitatively supporting the accumulated insights so far, it is possible to instruct individual players.

According to the driving method learning apparatus of the present invention, if the support means is a separate personal computer, the measurement alarm unit can be made small, while the high performance and large screen of the personal computer can be used, so that support is easy.

According to the running method learning apparatus of the present invention, when it is a self-contained type in which a support means is incorporated in the measurement alarm unit, it is possible to save the trouble of once stopping running and moving to the place where the personal computer is located and connecting to the personal computer.

According to the running method learning apparatus of the present invention, when the “detection system λ” composed of only the acceleration detection means is adopted as the detection means, there is an advantage that the angular velocity can also be measured. The unit conversion coefficient can be set only by applying gravitational acceleration, so that a device for rotating the measurement alarm unit at a constant angular velocity (for example, a wheel) is unnecessary and is simpler than the “detection system θ”.

According to the running method learning apparatus of the present invention, when the “detection system θ” configured by combining the acceleration detection means and the angular velocity detection means is adopted as the detection means, the number of parts is reduced and the measurement alarm unit is further downsized. be able to.

According to the running method learning apparatus of the present invention, since a 1-axis to 3-axis acceleration detecting means can be used as the detecting means, the optimum configuration can be selected at the time of designing in consideration of the stability of parts procurement and the part price.

According to the running method learning apparatus of the present invention, if the Y axis passes through the runner's navel, that is, the measurement alarm unit is arranged around the abdominal navel, the force applied to the vicinity of the center of gravity of the body can be measured. Therefore, there is an advantage that it is possible to measure a force that comprehensively reflects the motion of the foot, arm, and head, and there is an advantage that the angular velocity of the pelvis can be measured because the distance from the pelvis is short.

According to the running method learning device of the present invention, if the Y axis passes through the runner's lumbar spine, that is, the measurement alarm unit is arranged around the lumbar spine on the back of the runner, it is the same as the case where it is arranged around the umbilicus. Although there is an advantage, the runner has the advantage of being able to select the vicinity of the lumbar spine as the placement location depending on the preference of the wearing feeling, although the switch operability is inferior.

According to the driving method learning apparatus of the present invention, one or more alarm transmission means can be selected from the acoustic transmission means, vibration transmission means, light transmission means, or image display means. You can choose.

According to the driving method learning apparatus of the present invention, the following alarms are included: forward / backward translational acceleration positive target value excess alarm, forward / backward translational acceleration negative target value excess alarm, lateral translational acceleration absolute value target value excess alarm, lateral translational acceleration positive About matters that runners want to improve, because they can be selected from the target value excess alarm, left-right translational acceleration negative target value excess alarm, vertical translational acceleration positive target value excess alarm, and angular velocity absolute value target value excess alarm. Only specific and detailed corrections can be made.

According to the running method learning apparatus of the present invention, since the degree of deviation from the target value can be displayed as an alarm, the runner not only knows that the target value has been exceeded, but also knows how far the deviation has occurred. It becomes easier to modify the law.

According to the running method learning device of the present invention, the frequency distribution graph includes a maximum frequency distribution graph for each step in the longitudinal translation acceleration, a minimum frequency distribution graph for each step in the longitudinal translation acceleration, and a horizontal direction. Frequency distribution graph of the maximum value of each step of the translation acceleration, frequency distribution graph of the maximum value of the translation acceleration in the left and right direction, frequency distribution graph of the minimum value of the translation acceleration in the left and right direction, up and down Since it is possible to select from the frequency distribution graph of the maximum value for each step of the translational acceleration in the direction and the frequency distribution graph of the maximum value for each step of the absolute value of the angular velocity, it is easy to examine and determine the target value.

The measurement alarm unit and separate support means are always connected wirelessly, and guidance is provided based on the measurement data sent to the support means as needed while the runner is wearing the measurement alarm unit on his body. If the user draws a desired graph etc. on the screen of the support means, sets a new target value and sends a new alarm to the runner who is traveling to the measurement alarm section, without stopping the travel Practice efficiently. Also, runners do not have to return to the place where they have support.

When the measurement alarm unit and a separate support means are always connected wirelessly and the running means can issue voice instructions from the support means, the runner wears the measurement alarm part on the body. Based on the measurement data sent from time to time to the support means while driving, the instructor draws a desired graph etc. on the screen of the support means, and sets a new target value so that it is close to it It is possible to convey a suitable instruction to the runner by voice.

The support means and a display device such as a large screen in the running stadium are connected by wire or wireless, and the frequency distribution graph and target value created by the support means are displayed on the large screen etc. If you are able to run while checking the frequency distribution graph and target value by looking at etc., the runner can visually confirm the frequency distribution graph and target value by himself while running, so learning the driving method Accelerates.

The EEPROM 208 is a serial EEPROM and has a capacity of 64 KBYTE. The EEPROM 208 is a measurement value storage unit 127 (FIG. 6) and a setting value storage unit 128.

The data storage control switch 210 is a push button switch, and instructs to start and stop recording of measured values.

The stereo earphone terminal 209 transmits an alarm sound to the runner's ear through the stereo earphone 220.

The pilot lamp 219 is, for example, a light-emitting diode, and notifies the runner of the energized state, the recording state (during recording or stoppage of measurement value), the presence or absence of the remaining storage means, etc., with a blinking cycle.

The communication unit 211 includes an RS-232C level converter 212 and an RS-232C communication terminal 213. The RS-232C level converter 212 is an integrated circuit that adjusts the voltage of the communication line to the standard, and is means for enabling RS-232C communication with the personal computer 3. The RS-232C communication terminal 213 is a connector for connecting the communication cable 222. The communication means 211 is used only when connected to the personal computer 3, and is not used when the runner wears the measurement alarm device 2 on his body.

The personal computer 3 as support means receives measured values and set values from the measurement alarm device 2 after traveling, calculates translational acceleration and angular velocity, draws a frequency distribution graph, supports target value examination, and unit conversion Coefficients, alarm assignments, target values, etc. are transmitted for recording in the measurement alarm device 2.

Hereinafter, the operation of the measurement alarm device 2 will be described with reference to FIGS. 18 and 19.

<Measurement alarm operation mode>

When the power switch 216 of the measurement alarm device 2 is turned on, the CPU 202 starts executing software (301). The end is performed by turning off the power switch 216 of the measurement alarm device 2.

The setting value stored in the EEPROM 208 is read (302).

A message is sent to the personal computer 3 to wait for a response (303).

If there is a response within a predetermined time, it is determined that the personal computer 3 is connected, and the setting value inquiry / setting / measurement value inquiry shown in FIG. 19 is executed (304).

If there is no response within a predetermined time, it is determined that the personal computer 3 is not connected, and the process proceeds to the next process 305. Hereinafter, a case where the personal computer 3 is not connected and there is no response, that is, a case where the runner wears the measurement alarm device 2 will travel will be described.

The period of the period timer is set with the measurement period acquired from the EEPROM 208, set to cause a timer interrupt (310) for each measurement period, and the period timer is started (305).

If the recording state is “recording stopped” when the pressing of the data storage control switch 210 is detected (306, 307), the measurement value recording start preparation process is performed, and the recording state is set to “recording” ( 308). If the recording state is “recording” when the pressing of the data storage control switch 210 is detected (306, 307), the data recording end processing is performed, and the recording state is set to “recording stopped” (309).

<Timer interrupt>

When a timer interrupt is generated by the periodic timer, the voltage signals of the acceleration sensors a, b, and c that have passed through the operational amplifier 207 are measured by the AD converter 205 to obtain a digital value of the voltage (311).

The digital values of the voltages of the acceleration sensors a, b, and c are added to the following counting variables (312). The initial value of the counting variable is zero.
1) Add the digital value of the X component voltage of the acceleration sensor a to the counting variable “sx1 ″” 2) Add the digital value of the Y component voltage of the acceleration sensor a to the counting variable “sy1 ″” 3) Count the variable “sx2 ″” 4) Add the digital value of the X component voltage of the acceleration sensor b to 4) Add the digital value of the Y component voltage of the acceleration sensor b to the counting variable “sy2”. 5) Add the Z component voltage of the acceleration sensor c to the counting variable “sz”. 6) Add 1 to the number of counts

Determine the arrival of the recording cycle. That is, if the number of counts = recording cycle / measurement cycle, since the recording cycle has been reached, the next command is executed (313).
If the number of counts <recording cycle / measurement cycle, the recording cycle has not been reached, so the process returns to the interrupt source (313, 323).

The count values of the digital values of the voltages of the acceleration sensors a, b, and c are divided by the number of counts to calculate an average value for each, and the count variable is calculated (314).
1) Average digital value of X component voltage of acceleration sensor a ← sx1 ″ / count 2) Average digital value of Y component voltage of acceleration sensor a ← sy1 ″ / count 3) Average digital of X component voltage of acceleration sensor b Value ← sx2 "/ count count 4) Average digital value of Y component voltage of acceleration sensor b ← sy2" / count count 5) Average digital value of Z component voltage of acceleration sensor c ← sz "/ count count

The digital values of the voltages of the acceleration sensors a, b, and c are converted into acceleration by (Equation 6) (314). Here, since the average value during the recording period is used as the acceleration to be compared with the target value, “average digital value” is substituted for the variable (digital value). Therefore, (Equation 6) is as follows.
Acceleration = 2 / (A−B) · Average digital value−2 · (A / (A−B)) + 1 (Formula 6)
Here, coefficients A and B are unit conversion coefficients. The unit is the acceleration G of gravity.
The coefficients A and B have the X and Y axes of the acceleration sensors a and b and the Z axis of the acceleration sensor c as follows.
1) Digital value (A) corresponding to the X axis + 1G acceleration of the acceleration sensor a
2) Digital value (B) corresponding to the X-axis -1G acceleration of the acceleration sensor a
3) Digital value corresponding to the + 1G acceleration on the Y axis of the acceleration sensor a (A)
4) Digital value (B) corresponding to -1G acceleration on the Y axis of the acceleration sensor a
5) Digital value (A) corresponding to + 1G acceleration on the X axis of the acceleration sensor b
6) Digital value (B) corresponding to the X-axis -1G acceleration of the acceleration sensor b
7) Digital value (A) corresponding to the + 1G acceleration on the Y axis of the acceleration sensor b
8) Digital value (B) corresponding to -1G acceleration on the Y axis of the acceleration sensor b
9) Digital value corresponding to the + 1G acceleration of the Z axis of the acceleration sensor c (A)
10) Digital value (B) corresponding to -1G acceleration of Z-axis of acceleration sensor c

According to (Equation 6), each acceleration is calculated and stored in the following variables.
x1 ″ ← X component of acceleration obtained from acceleration sensor a y1 ″ ← Y component of acceleration obtained from acceleration sensor a x2 ″ ← X component of acceleration obtained from acceleration sensor b y2 ″ ← Acceleration component obtained from acceleration sensor b Y component z "<-Z component of acceleration obtained from acceleration sensor c

The lateral translation acceleration X ″, the longitudinal translation acceleration Y ″, the vertical translation acceleration Z ″, and the angular velocity ψ ′ are calculated by the following equations (315).
X ″ = (x1 ″ + x2 ″) / 2+ (y1 ″ −y2 ″) R / L (Formula 1)
Y ″ = (y1 ″ + y2 ″) / 2− (x1 ″ −x2 ″) R / L (Formula 2)
Z ″ = z ″ (Formula 8)
ψ ′ = {(x2 ″ −x1 ″) · 9.8 / L} ^ 0.5 (Formula 9)
However, if (x2 ″ −x1 ″) <0, ψ ′ = 0. The unit of X ″, Y ″ and Z ″ is the acceleration of gravity G, and the unit of ψ ′ is rad / sec. L is the distance between the acceleration sensor a and the acceleration sensor b (unit is m as shown in FIG. 7). ) Is built in as a device constant, where R is the distance (unit: m) between the origin O and the midpoint 145 of the acceleration sensors a and b in FIG 7. R is calculated as follows.

When the “distance r between the Z axis passing through the midpoint N of the line segment connecting the left and right greater trochanters and the measurement alarm device mounting portion” obtained from the EEPROM 208 is positive, that is, the measurement alarm device 2 is placed on the front surface of the body (umbilical side). ), R = r + Hb. Here, Hb is the distance from the back surface of the measurement alarm device 2 to the acceleration sensor as shown in FIG. 7 (FIG. 9). When r is negative, that is, when the measurement alarm device 2 is attached to the back (back side) of the body, R = r−Ha. Here, Ha is the distance from the back surface of the measurement alarm device 2 to the acceleration sensor as shown in FIG. 7 (FIG. 9). The unit of r, Ha, Hb is m. The constant 9.8 in (Equation 9) is the acceleration of gravity, and the unit is m / second · second.

Although the Z axis is in the vertical direction in principle, the Z axis slightly deviates from the vertical direction depending on the method of mounting the measurement alarm device 2, the forward tilting posture during traveling, and the like. Due to this deviation, Z ″ is mixed into Y ″ and X ″. To correct this, Z ″ is multiplied by the moving average of measured values of about 50 points (about 1 second) for X ″ and Y ″. Subtract the value. As long as the runner does not run on an extremely curved road, the average speed of the translational acceleration Y "and X" in the horizontal direction is 0 [G] because the average is 0 [G]. 1 [G]. Therefore, if the moving average of Y ″ and X ″ is not 0 [G], it can be regarded that Z ″ is mixed only by the sine component of the deviation angle of the Z axis. The influence on the translational acceleration Z ″ is insignificant.

<Warning alert stop>

The process of stopping the alarm sound is performed for each alarm transmission means (left ear and right ear of the stereo earphone) as follows.

If a warning sound is being issued to the warning transmission means and a predetermined warning sound time has elapsed, the warning is stopped (316, 317, 318).

If no alarm sound is issued to the alarm transmission means, nothing is done (316, 317).

<Beginning alarm sound>

For the following alarm types 1) to 7), the alarm sound issue start processing is executed as follows. That is, when the alarm type is assigned to an alarm and the translational acceleration or angular velocity corresponding to the alarm type exceeds the target value of the alarm type, the translational acceleration is connected to the alarm-assigned stereo earphone terminal. Alternatively, an alarm sound is generated at a frequency corresponding to the absolute value of the difference between the angular velocity and the target value (319, 320). When the target value warning for each sign of the lateral translation acceleration is not used, 4) and 5) may be excluded from the implementation.
1) Longitudinal translational acceleration positive target value excess alarm 2) Longitudinal translational acceleration negative target value excess alarm 3) Horizontal translational acceleration absolute value target value excess alarm 4) Lateral translational acceleration positive target value excess alarm 5) Lateral translation Acceleration negative target value excess alarm 6) Vertical translation acceleration positive target value excess alarm 7) Angular velocity absolute value target value excess alarm.
Details are described below.

If the forward / backward translational acceleration positive target value excess alarm is assigned as an alarm, and the longitudinal translational acceleration exceeds the forward / backward translational acceleration positive target value in the forward direction, the CPU is assigned to the alarm-assigned stereo earphone. An alarm sound is generated at the terminal at a frequency corresponding to the absolute value of the difference between the longitudinal translational acceleration and the longitudinal translational acceleration positive target value.

When the forward / backward translational acceleration negative target value excess alarm is assigned an alarm, and the longitudinal translational acceleration exceeds the forward / backward translational acceleration negative target value in the negative direction, the CPU is assigned to the alarm-assigned stereo earphone. An alarm sound is generated at the terminal at a frequency corresponding to the absolute value of the difference between the longitudinal translational acceleration and the longitudinal translational acceleration negative target value.

If the left-right translational acceleration absolute value target value excess alarm is assigned an alarm, and the absolute value of the left-right translational acceleration exceeds the left-right translational acceleration absolute value target value, the CPU An alarm sound is generated at a frequency corresponding to the absolute value of the difference between the absolute value of the lateral translation acceleration and the absolute value of the lateral translation acceleration absolute value on the stereo earphone terminal.

If the left-right translational acceleration positive target value excess alarm is assigned an alarm, and the left-right translational acceleration exceeds the left-right translational acceleration positive target value in the positive direction, the CPU is assigned to the stereo earphone on the alarm assigned side. An alarm sound is generated at a frequency at a frequency corresponding to the absolute value of the difference between the lateral translation acceleration and the lateral translation acceleration positive target value. In addition, when the target value excess warning according to code | symbol of the translational acceleration in the left-right direction is not required, the warning sound generation may be excluded from the implementation.

If the left-right translational acceleration negative target value excess alarm is assigned an alarm, and the left-right translational acceleration exceeds the left-right translational acceleration negative target value in the negative direction, the CPU is assigned to the alarm-assigned stereo earphone. An alarm sound is generated at the terminal at a frequency corresponding to the absolute value of the difference between the lateral translation acceleration and the lateral translation acceleration negative target value. In addition, when the target value excess warning according to code | symbol of the translational acceleration in the left-right direction is not required, the warning sound generation may be excluded from the implementation.

If the vertical translation acceleration positive target value excess alarm is assigned an alarm, and the vertical translation acceleration exceeds the vertical translation acceleration positive target value in the positive direction, the CPU is assigned to the stereo earphone on the alarm assigned side. An alarm sound is generated at the terminal at a frequency corresponding to the absolute value of the difference between the vertical translation acceleration and the vertical translation acceleration positive target value.

When the angular velocity absolute value target value excess alarm is assigned to the alarm and the angular velocity exceeds the angular velocity absolute value target value, the CPU sets the angular velocity and the angular velocity absolute value target value to the stereo earphone terminal on the alarm assigned side. An alarm sound is generated at a frequency corresponding to the absolute value of the difference between the two.

When the recording state is “recording” and there is room for recording in the EEPROM 208, the accelerations “x1 ″”, “y1 ″”, “x2 ″”, “y2 ″”, “z ″” are written in the EEPROM 208. At this time, if there is no room for recording in the EEPROM, the recording state is set to “recording stopped” (321, 322).

Return to the interrupt source (323).

<Measurement alarm setting value inquiry / setting / measurement value inquiry mode>

When the measurement alarm device 2 sends a message via the communication means 211 (FIG. 17), if there is a response within a predetermined time, it is determined that the personal computer 3 is connected, and the set value inquiry / setting of FIG. Start the measurement value inquiry (401). The end is performed by turning off the power switch of the measurement alarm device 2.

A command is received from the personal computer 3 (402).

When the command is “data inquiry”, the measured value is taken out from the EEPROM 208 and transmitted to the personal computer 3 (403, 404).

When the command is “reference value inquiry”, the setting value is transmitted to the personal computer 3 (405, 406).

When the command is “update set value”, the set value is received from the personal computer 3 (407, 408). Note that writing to the EEPROM 208 is not performed until there is a set value write command from the personal computer 3.

When the command is “unit conversion coefficient setting”, the voltages of the acceleration sensors a, b, c are measured by the AD converter 205 (409, 410).
The AD conversion value of the axis designated by the command is taken out, and a digital value corresponding to the unit acceleration (+1 [G], -1 [G]) of the designated sign is recorded in the RAM 204 as a unit conversion coefficient (411). Note that writing to the EEPROM 208 is not performed until a writing command is issued from the personal computer 3.

Since the axis information includes XYZ and the sign information includes + −, the “unit conversion coefficient setting” command is subdivided into six types of commands. The operator operates the personal computer 3 and issues an instruction to the measurement alarm 2 while handling the measurement alarm 2 as follows.

The operator gives an acceleration of +1 [G] to the X-axis with the right side (X-axis positive direction) of the measurement alarm 2 facing right up, and then gives an instruction “Measure + 1G on the X-axis”. 2, the measurement alarm device 2 measures the acceleration of the X axis for the acceleration sensors a and b, digitizes it, and records this as a digital value corresponding to + 1G of the X axis.

The operator gives an acceleration of −1 [G] to the Y axis with the rear side of the measurement alarm device 2 (Y-axis negative direction) right above, and then instructs “Measure -1G on the Y axis”. When given to the measurement alarm device 2, the measurement alarm device 2 measures the acceleration of the Y axis for the acceleration sensors a and b, digitizes it, and records this as a digital value corresponding to -1G of the Y axis.

The operator gives an acceleration of +1 [G] to the Z-axis with the upper side (Z-axis positive direction) of the measurement alarm 2 facing right up, and then gives an instruction “Measure + 1G on the Z-axis”. When given to 2, the measurement alarm 2 measures the Z-axis acceleration, digitizes it, and records it as a digital value corresponding to + 1G on the Z-axis.

The operator gives the acceleration of -1 [G] to the X-axis with the lower side of the measurement alarm 2 (Z-axis negative direction) right above, and then instructs “Measure -1G on the Z-axis”. When given to the measurement alarm device 2, the measurement alarm device 2 measures the Z-axis acceleration, digitizes it, and records this as a digital value corresponding to -1G on the Z-axis.

If the command is “query unit conversion coefficient”, the unit conversion coefficient on the RAM 204 is transmitted to the personal computer 3 (412, 413).

When the command is “operation check”, the voltage of the acceleration sensors a to c is measured by the AD converter 205, the digital value of the acquired voltage is converted into acceleration by (Equation 6), and the acceleration data is sent to the personal computer 3. Send. (414, 415, 416).

When the command is “write set value”, the set value and the unit conversion coefficient currently stored in the RAM 204 are written to the EEPROM. (417, 418).

Next, software on the personal computer 3 side (hereinafter simply referred to as “PC software”) will be described with reference to FIGS.

<Acquisition of measured value from measurement alarm by personal computer>

With reference to FIG. 20, “measurement value acquisition from the measurement alarm” will be described. When the measurement alarm device 2 and the personal computer 3 that have been turned off are connected by the communication cable 222 (FIG. 17) and the “measurement value reading from the measurement alarm device” of the personal computer software is started, the personal computer software Wait for a message (501, 502).

When the power switch 216 of the measurement alarm device 2 is turned on, the measurement alarm device 2 transmits a message via the communication means 211, and the personal computer software receives the message and returns a response to the measurement alarm device 2 to establish communication. (503)

The personal computer software transmits a “set value inquiry” command to the measurement alarm device 2 and receives the set value from the measurement alarm device 2 (504, 505).

The personal computer software transmits a “measurement value inquiry” command to the measurement alarm device 2 and receives measurement values from the measurement alarm device 2 (506, 507).

The personal computer software saves the received data (consisting of the set value and the measured value) in a file, and finishes “loading the measured value from the measurement alarm” (508, 509). The operator turns off the power switch 216 of the measurement alarm.

<Support for studying target values in personal computers>

“Target value examination support” will be described with reference to FIG. When the operator activates “target value examination support” of the personal computer software of the personal computer 3, the personal computer software displays a list of stored received data files on the screen (601, 602).

When the operator selects a received data file from the list, the personal computer software reads the designated received data file (603, 604).

The PC software calculates the translational acceleration X ″ Y from the measured values (acceleration x1 ″, y1 ″, x2 ″, y2 ″, z ″) of the received data file by (Expression 1), (Expression 2), (Expression 8), and (Expression 9). “Z” and angular velocity ψ ′ are calculated, and X ″ and Y ″ are corrected by a moving average of about 50 points (605).

The data string of translational acceleration and angular velocity arranged in time series is divided into data strings for each step according to the peak of translational acceleration Z ″ (606).

The maximum value and the minimum value for each step of the translational acceleration X "Y" Z "and the angular velocity ψ 'of each axis are obtained from the data sequence for each step (607).

The frequency distribution graph of the maximum value and the minimum value for each step is displayed on the screen (608). There are, for example, the following seven types of frequency distribution graphs, and the display can be switched in accordance with instructions from the operator.
a) Frequency distribution graph of maximum value for each step of translational acceleration in the longitudinal direction b) Frequency distribution graph of minimum value for each step of translational acceleration in the longitudinal direction c) Maximum value of absolute value of translational acceleration in the horizontal direction for each step D) Frequency distribution graph of maximum value for each step of translational acceleration in the left-right direction e) Frequency distribution graph of minimum value for each step of translational acceleration in the left-right direction f) Maximum of each step of translational acceleration in the vertical direction Frequency distribution graph of values g) Frequency distribution graph of the maximum value for each step of absolute value of angular velocity

The type of the frequency distribution graph to be displayed first may be fixed, or the frequency distribution graph of the type displayed at the end of the previous operation may be displayed so that the personal computer software keeps an operation record. Note that unnecessary graphs may not be displayed.

The personal computer software displays a cursor line (609). The cursor line is a line perpendicular to the acceleration axis and angular velocity axis of the frequency distribution graph, and can be moved on the frequency distribution graph by the operation of the operator. When the cursor line is displayed for the first time on this type of graph, the coordinate value may be a median (a value that divides the frequency into two) or an arbitrary coordinate value within the data range of the frequency distribution.

The personal computer software receives an instruction from the operator (610).

If the instruction is “cursor line move”, the cursor line is redrawn with the instruction and how much alarm is issued when the cursor line coordinate value on the acceleration axis or angular velocity axis and the cursor line are the target value Is displayed as the alert rate. (611, 609). The operator can move the cursor line and examine the target value.

If the instruction is “switching the type of frequency distribution graph”, the personal computer software draws the specified frequency distribution graph (612, 608).

If the instruction is “print”, printing is performed by a printer (not shown) connected to the screen (613, 614).

When the instruction is “end”, the target value examination support is ended (615, 616).
If it is any other instruction, the instruction is again waited (615, 610).

<Inquiry and setting of setting value on personal computer>

“Setting value inquiry / setting” will be described with reference to FIG. When the operator connects the measurement alarm device 2 whose power is turned off to the personal computer 3 with the communication cable 222 and starts “setting value inquiry / setting” of the personal computer software, the personal computer software waits for a message from the measurement alarm device 2 ( 701, 702).

When the operator turns on the power switch 216 of the measurement alarm device 2, the measurement alarm device 2 transmits a message via the communication means 211, and the personal computer software receives the message and returns a response to the measurement alarm device 2. (703)

The personal computer software transmits a “set value inquiry” command to the measurement alarm device 2 and receives the set value from the measurement alarm device 2 (704, 705).

The personal computer software transmits a “unit conversion coefficient inquiry” command to the measurement alarm device 2 and receives the unit conversion coefficient from the measurement alarm device (706, 707).

The personal computer software displays the received set value and unit conversion coefficient (708). The operator can input the examined target value on this screen.

The personal computer software receives a set value input and command from the operator (709).

When the command is “set value transmission”, the set value update command and the set value are transmitted to the measurement alarm device 2, then the set value write command is transmitted, and the command is waited again (710, 711, 712, 709). ). The set value writing command is a command for writing not only the set value on the screen but also the unit conversion coefficient in the EEPROM 208.

When the command is “operation check”, the operation check command is transmitted to the measurement alarm device 2, the acceleration data is received from the measurement alarm device 2, the acceleration data is displayed on the screen, and the command is waited again (713, 714). 715, 716). The operator confirms how the measurement alarm 2 captures the acceleration.

If the command is “Unit conversion coefficient setting”, after sending the unit conversion coefficient setting command, send the unit conversion coefficient inquiry command, display the unit conversion coefficient received from the measurement alarm device 2 on the screen, (717, 718, 719, 720, 721). The unit conversion coefficient recorded in the measurement alarm device 2 has not yet been written in the EEPROM, and in order to write it, it is necessary to issue a set value transmission command (709, 710).

When the command is “end”, the setting value inquiry / setting is ended (722, 723). If the instruction is other than that, it waits for the instruction again (723, 709).

Below, the case where a running method is actually learned using the running method acquisition apparatus of this invention is demonstrated.

<Procedure when using a measurement alarm for the first time>

When the runner uses the measurement alarm device 2 for the first time, he / she has to make a trial run in order to set a target value. The unit conversion coefficient is set at the time of manufacture as shown in Table 1, for example.

Prior to the run of the runner, the measurement alarm device 2 is connected to the personal computer 3, and the following values are set in the measurement alarm device 2 by the personal computer 3.
1) “r” (the distance between the Z-axis passing through the midpoint of the line segment connecting the left and right greater trochanters and the measurement alarm mounting unit, for example, the Y coordinate value of 142 in FIG. 7). r is positive if the attachment site is the front of the body and negative if the attachment site is the back. Here, r was 84 mm, and the apparatus constant (distance) Hb was 16 mm.
2) “Measurement cycle”. It was 5 milliseconds.
3) “Recording cycle”. Set 20 to 25 milliseconds for medium and long distances, and 10 to 20 milliseconds for short distances. Here, it was set to 20 milliseconds.
4) Other values remain as set at the time of manufacture.

The measurement alarm device 2 is disconnected from the personal computer 3 and is sandwiched between the double central portion 5 of the belt 4 as shown in FIGS. 13 to 15, and the center 145 of the measurement alarm device 2 is placed at the place of the umbilicus 142 (FIG. 7). Then, the belt 4 is wound around the abdomen so as to be fixed, and both ends of the belt 4 are fixed by the hook-and-loop fastener 6. The stereo earphone 220 is originally attached to both ears, but it is not necessary to attach the stereo earphone 220 since it is a trial run.

The power switch 216 is turned on and the lighting of the pilot lamp 219 is confirmed.

Start running.

When the cruise speed is reached, the data storage control switch 210 is pressed to start recording the measured value. Continue running while recording for more than 100 steps, at least 50 steps, 30 seconds or more, and at least 15 seconds.

The data storage control switch 210 is pressed to finish recording the measured value.

The travel is stopped and the power switch 216 is disconnected.

When the traveling is finished, the measurement alarm device 2 is connected to the personal computer 3. The personal computer 3 receives the measured value and the set value from the measurement alarm device 2.

The personal computer 3 obtains the translational acceleration and the angular velocity from the digital values measured by the measurement alarm device 2 as shown in Table 2.

Table 2 shows the measurement data for one step. In Table 2, “Measured value (digital value)” is the value obtained by digitizing the output of the acceleration sensor with an AD converter, etc., every 5 milliseconds for 20 milliseconds. It is the average value of the measured values. A value obtained by substituting the “measured value (digital value)” and the unit conversion coefficient of Table 1 into (Equation 6) is the “measured value after unit conversion”. “Translation acceleration” and “angular velocity” are values obtained by substituting “measured values after unit conversion” into (Expression 1), (Expression 2), (Expression 8), and (Expression 9). In the formula, L was 17.5 mm and R was 100 mm.

In addition, you may make it utilize what the control means of the measurement alarm device 2 calculated | required, without the personal computer 3 calculating | requiring a translation acceleration and an angular velocity uniquely.

A time series graph of translational acceleration and angular velocity as shown in FIG. 23 (showing measurement data for three steps) was created from the obtained translational acceleration and angular velocity using the personal computer 3.

As can be seen in FIG. 23, the vertical translational acceleration Z ″ shows a large peak 806 for each step, and the data string is changed to a data string for each step, with the midpoint between adjacent peaks of Z ″ as one step delimiter. Can be separated.

Further, the next value was picked up from the data sequence for each step by the target value examination support means.
a) Maximum value for each step of translational acceleration Y "in the front-rear direction (802 in FIG. 23)
b) Minimum value for each step of translational acceleration Y "in the front-rear direction (801 in FIG. 23)
c) Maximum absolute value of the translational acceleration X ″ in the left-right direction for each step (805 in FIG. 23)
d) Maximum value for each step of translational acceleration X "in the left-right direction (803 in FIG. 23)
e) The minimum value for each step (804 in FIG. 23)
f) Maximum value for each step of translational acceleration Z ″ in the vertical direction (806 in FIG. 23)
g) Maximum value of absolute value of angular velocity for each step (807 in FIG. 23)

The target value examination support means draws a frequency distribution graph with the maximum value or the minimum value picked up from the data sequence for each step, with the vertical axis representing the frequency and the horizontal axis representing the translational acceleration. Here, using the measurement data for 53 steps, a “frequency distribution graph of minimum values for each step of translational acceleration in the front-rear direction” as shown in FIG. 24 is drawn.

The following graph may be drawn instead of or together with the “frequency distribution graph of the minimum value for each step of translational acceleration in the front-rear direction”.
Frequency distribution graph of maximum value for each step of translational acceleration in the longitudinal direction Frequency distribution graph of maximum value for each step of translational acceleration in the horizontal direction Frequency distribution graph of maximum value for each step of translational acceleration in the horizontal direction Frequency distribution graph of minimum value for each step of translational acceleration of frequency distribution graph of maximum value for each step of translational acceleration in the vertical direction Frequency distribution graph of maximum value for each step of absolute value of angular velocity

Next, the target value is examined using a graph as shown in FIG. 24 displayed on the screen of the personal computer 3. 24 is a frequency distribution graph of the minimum value for each step of translational acceleration in the front-rear direction, and is also a frequency distribution graph of the maximum brake for each step. The left side of FIG. 24 has a large brake and the right side is small.
In determining the target value, the value is such that the frequency is 1 or more in both the range smaller than the target value and the larger range. In other words, the target value is set so that the alert rate (the ratio of the alert alert steps to the total number of steps expressed as a percentage) is greater than 0% and less than 100%. If the target value is set to a value less than -2.4G in Fig. 24, the alert rate is 0% and no alarm is issued. If the target value is set to a value greater than -1.0G, the alert rate is It becomes 100%, and an alarm is issued at every step.

Here, a target value of -1.55G is set, and a cursor line 901 that can be moved left and right by a key operation is set there. The cursor line coordinate value on the translation acceleration Y ″ axis at that time is shown as 902.
Accordingly, the target value on the right side of the cursor line 901 has achieved the target value, and the left side thereof has not reached the target value. In the next actual running, an alarm is issued for the longitudinal translation acceleration as shown on the left side of the cursor line 901 in FIG. 24, and no warning is issued on the right side. Note that reference numeral 903 denotes an alert rate when such a target value is set.

<Production run>

The procedure for using the measurement alarm device 2 for actual running is as follows.

The target value and alarm assignment are set in the measurement alarm device 2 from the personal computer 3. Here, −1.55 [G] is set as the negative target value for the longitudinal translation acceleration, and 4.0 [G] is set as the positive target value for the vertical translational acceleration. Alarms are assigned to the right and left of the stereo earphone terminal, respectively. .

The measurement alarm device 2 separated from the personal computer 3 is fixed to the body with the belt 4 in the same manner as the trial run, and the stereo earphone 220 is attached to both ears.

The power switch 216 is turned on and the lighting of the pilot lamp 219 is confirmed.

Start running.

While being conscious of the alarm sound that can be heard from the stereo earphone 220, trial and confirmation are performed step by step.

Since the forward / backward translational acceleration negative target value excess alarm is assigned as an alarm, for example, the alarm appears on the right side of the stereo earphone at point P of 801 belonging to the second step in FIG. In this way, for example, a “form to be stepped down” is searched for by raising the head, sticking out the stomach, or landing from the heel.

In addition, since the up / down translational acceleration positive target value excess warning is assigned as another warning, for example, the warning appears on the left side of the stereo earphone at the point Q of 806 belonging to the first step in FIG. Thus, for example, the “form with reduced vertical movement” is searched for by reducing how to raise the thighs or shortening the stride while maintaining the speed.

If the forward / backward translational acceleration positive target value excess warning is assigned, for example, the kicked foot heel will not jump up to the buttocks, or the timing of getting on the landing foot will be changed. (This time, no warning is given, so this warning will not be issued. The same shall apply hereinafter.)

When the alarm for exceeding the absolute value of the target value of translational acceleration in the left-right direction is assigned, for example, by changing the distance between the lines connecting the left and right footprints or changing the direction of the toes (outside or inside) of the landing foot, Search for “restrained form”.

If the left / right translational acceleration positive target value excess warning is assigned, for example, by shifting the line connecting the footprints of the right foot to the right, or opening the toes of the landing foot of the left foot outwards, `` a form that suppresses rightward swing '' Explore.

For left-right translational acceleration negative target value excess warning, search for `` form with reduced leftward swing '' by shifting the line connecting the footprint of the left foot to the left or opening the toe of the landing foot of the right foot outward, for example .

When the absolute velocity target value excess warning is assigned, for example, change the distance between the lines connecting the left and right footprints, change the direction of the toes of the landing foot (outside or inside), or step forward on the kicked foot When searching for “forms with reduced rotation of the pelvis”, such as moving the waist before the feet.

As described above, the difference between the one step when the warning was issued and the one that was not issued is the ratio of one step to several steps (if the target value is median, one step to two steps). You can think about it and make corrections and confirmations step by step.

If the alarm frequency is sufficiently reduced, the data storage control switch 210 is pressed to start recording a new measurement value. This is data for setting the next driving target.

The data storage control switch 210 is pressed to finish recording the measured value.

The travel is stopped and the power switch 216 is disconnected.

The measurement alarm device 2 is connected to the personal computer 3, the measurement value and the set value are received from the measurement alarm device 2, and the frequency distribution graph of the maximum value and the minimum value for each step of translational acceleration and angular velocity is again drawn on the personal computer 3. Let's consider a new target value.

When a new target value is determined, the new target value and alarm assignment are transmitted from the personal computer 3 to the measurement alarm device 2 and set.

Recording of measurement values is not limited to the above case, but measurement values are recorded when you become aware of problems such as how you run when you are tired and how you run uphill or downhill. can do. It is also possible to discover fellows who have achieved superior running methods compared to fellow runners' data and ask them for checkpoints for research.
