Abstract

PROBLEM TO BE SOLVED: To previously prevent overstraining to the runner who is carrying out circumferential speed increasing type training by providing a hint for carrying out optimum training to the runner, and also by monitoring the relationship between the number of pulse waves for each circumference and the running speed, so that warning can be given when the physical conditions of the runner deviate from those of normal conditions. SOLUTION: The pulse waveforms of a runner are measured by a pulse wave detector 4, and are converted into digital signals by a sensor interface 6. The runner depresses the lap button inside an operation part 10 for each time of circumference, and the running speed is increased as the times of circumference is increased. A CPU 1 obtains the maximum pulse number for each circumference and the required time from the outputs of the sensor interface 6 and the operation part 10, and the measured points are plotted on a display unit 7. Further, a most suitable line satisfying these measured points is determined by means of the method of least squares, and a variation point HRtp is detected from the deviation between the straight line and the measured points for each circumference, and this is displayed on the display unit 7.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a training assisting device for giving appropriate advice to a runner who conducts an increase in lap speed.

[0002]

2. Description of the Related Art Conventional training methods are based on so-called "physical exercise intensity".
This is, for example, a training method in which the goal is to run a predetermined distance within a predetermined time. It can be said that this training method is effective when the distance for one round is fixed and the training is performed in a track on a playground having a flat road surface. However, when using general roads and undulating mountain roads, if you train only based on the exercise intensity as described above, depending on the surrounding environment such as temperature and humidity, the physical condition of the runner himself, etc. There is a risk of overtraining.

As a measure for improving such a problem, training based on "physiological exercise intensity" has been attracting attention in recent years. This is to adjust the training amount by grasping the exercise intensity from the pulse rate and the like. Since the pulse rate responds sensitively to changes in the physical condition and the surrounding environment, adopting such a method makes it possible to train reasonably.

[0004]

By the way, conventionally, there is a means for objectively indicating to what degree of pulse rate it is best to perform training when a runner performs training based on physiological exercise intensity. I didn't. In addition, if the runner is not in good physical condition, performing the same training as usual will easily lead to overtraining. However, the runner does not always accurately recognize his physical condition, and he is subject to excessive training by relying only on his own feeling.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a guideline for performing optimal training for a runner who conducts training with an increased lap speed. . Another object of the present invention is to monitor the relationship between the pulse rate and the lap for each lap,
When the physical condition of the runner deviates from the normal condition, caution is required to prevent overtraining.

[0006]

In order to solve the above-mentioned problems, the invention according to claim 1 is a training support device for giving advice to a wearer who carries out a training of an increase in lap speed. Pulse rate calculating means for detecting the pulse wave of the pulse wave and calculating the pulse rate from the waveform of the pulse wave, an input means for reading a circling instruction performed by the wearer for each lap, a clocking means for measuring time, and the pulse In addition to determining the pulse rate in each lap by taking in the number, when the lap instruction is given, the time is read from the time measuring means, and a calculating means for calculating the lap of the wearer for each lap, and the lap The notification means is configured to notify the wearer of the relationship between the pulse rate calculated for each and the orbit lap.

According to a second aspect of the present invention, in the first aspect of the invention, storage means for storing the pulse rate and the lap lap calculated for each lap, and the lap at the end of each lap Based on the pulse rate and the lap lap immediately before, the predicted value of the pulse rate and the lap in the lap is calculated, the predicted value and the pulse rate in the lap and the lap of the lap When the deviation exceeds a predetermined value, the notification means has a control means for obtaining a deviation from a measured value, and the portable means using the pulse rate and the lap as a mutating point in a lap immediately before the lap is carried out. It is characterized by notifying the person.

According to a third aspect of the present invention, in the invention according to the second aspect, the control means applies the least squares method to the pulse rate and the lap lap up to the lap immediately before the lap. It is characterized in that a predicted value of the pulse rate and the lap of the lap is calculated. The invention according to claim 4 is the invention according to claim 1, further comprising: target setting means for setting the target value of the mutation point; and comparison means for comparing the target value of the mutation point with the actual measurement value of the mutation point. The notification means is characterized by issuing a warning to the wearer when the difference between the target value and the actual measurement value exceeds a predetermined value.

[0009]

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. First, in the present embodiment, the relationship between the pulse rate and the lap that are used to grasp the runner's state will be outlined. FIG. 2 shows an example of the relationship between the pulse rate of the runner and the lap. In the figure, the vertical axis represents the heart rate of the runner (≈pulse rate). The horizontal axis is not the runner's running speed itself, but the runner's orbital lap, and the time required to run 1 km is used. Note that the relationship shown in the figure can be obtained by expressing any of these quantities. Further, in the figure, a graph (a) is a characteristic of a jogger who is training about jogging, and a graph (b) is a characteristic of a racer who is training to compete in a competition. . In this way, the lap and the pulse rate have different relationships depending on the runner's age and physical fitness.

On the other hand, as shown in this figure, if the lap is less than a predetermined value, the heart rate increases in proportion to the lap. However, when the number of laps exceeds a predetermined value, the rate of increase of the heart rate with respect to the number of laps of the laps slows down, and finally becomes saturated (although not shown). Here, the change point at which the pulse rate and the orbit lap start to deviate from the proportional relationship is generally referred to as HRtp (Heart Rate tu
rn point). Further, the pulse rate at the time when the graph in the same figure is saturated is called the maximum pulse rate.

The mutation point HRtp varies depending on the day when the measurement is carried out, even if the same runner is measured. Such variations occur due to, for example, the physical condition of the runner on that day. If the physical condition of the runner is bad, the mutation point HRtp will fall. In other words, both the lap and the pulse rate are lower than usual, and the variation point H
Rtp appears. On the contrary, if the physical condition is good, the mutation point HRtp rises, and the mutation point HRtp does not appear until the circulation lap and the pulse rate are higher than usual. Moreover, the mutation point HRtp can be increased by accumulating heavy training.

It is known that the mutation point HRtp is slightly higher than the anoxic work threshold (Anaerobic Threshold, so-called AT value), but almost equal to the AT value. This AT value (hence the mutation point HRtp) is extremely important as an index for training, as shown below.

The energy synthesis system of the human body is roughly classified into aerobic metabolism that does not use oxygen and aerobic metabolism that requires oxygen. Of these, in the former anaerobic metabolism, the lactic acid system that produces lactic acid accounts for the majority. In addition, as the runner's heart rate increases, energy synthesis shifts from aerobic metabolism to anaerobic metabolism, but as is well known, anaerobic metabolism produces lactic acid, which causes runner fatigue. . Therefore, when performing a long-term endurance training such as the above-described lap training, it is effective to perform the training below the AT value. Furthermore, it is known that training is performed within the range of 70% of the maximum heart rate to the AT value to increase the AT value itself. As described above, knowing the mutation point HRtp is extremely useful for performing effective training.

Next, the configuration of the training support device according to the present embodiment will be described. FIG. 1 is a block diagram showing the configuration of the device. In the figure, a CPU (central processing unit) 1 is a central part that controls each circuit in the training support device, and its function will be described in the section of operation described later. A ROM (Read Only Memory) 2 stores a control program executed by the CPU 1 and various control data.

The RAM (random access memory) 3 is
In addition to being used as a work area when the CPU 1 performs calculations, the measured values of the pulse wave detection unit 4 described below and the calculation results of various calculations performed by the CPU 1 are stored. Further, as will be described later, the RAM 3 has a mutation point H over a predetermined period.
Since the measured value of Rtp is stored, it is desirable that the RAM 3 be a non-volatile memory.

The pulse wave detection unit 4 is a sensor for detecting the pulse wave waveform of the runner, and is, for example, an optical fingertip pulse wave sensor mounted on the finger of the runner or a wristwatch band. It is a sensor for detecting the pulse wave of the radial artery that is attached. Alternatively, the pulse wave detector 4 may be configured to directly detect the heart rate, for example, an existing heart rate monitor.

The sensor interface 6 takes in the output of the pulse wave detector 4 at a predetermined interval, converts the taken-in analog signal into a digital signal, and outputs it. The display device 7 is a device for presenting various messages to the runner and displaying a graph, and is, for example, a liquid crystal display device provided in a wristwatch.

The display control circuit 8 receives the display information from the CPU 1, converts the display information into a format used by the display device 7, and displays it on the display device 7. The clock circuit 9 has a function of transmitting an interrupt signal to the CPU 1 when the CPU 1 reaches a preset time or when the CPU 1 presets a time, in addition to the normal clock function.

The operation unit 10 is an input means for the runner to set various values in the apparatus. The operation unit 10 has various values such as a start / stop button for enabling / disabling the function of the apparatus, a lap button pressed every time the runner goes around a predetermined course, a target value of the variation point HRtp. Setting buttons (none of which are shown) for setting are provided, and the state of these buttons and various set values are output.

This device is usually worn and used by a runner as a portable device, and one example thereof is a mode in which it is combined with a wristwatch as shown in FIG. As shown in this figure, the training support device according to this embodiment includes a device main body 100 having a wristwatch structure, a cable 101 connected to the device main body 100, and a sensor unit 102 provided on the tip side of the cable 101. ing. A wristband 103 is attached to the main body 100 of the wristwatch, which is wound around the runner's arm from the 12 o'clock direction and fixed at the 6 o'clock direction. The device body 100 is detachable from the arm of the runner by the wristband 103.

The sensor unit 102 is shielded from light by a sensor fixing band 104, and is mounted between the root of the index finger of the runner and the second knuckle. When the sensor unit 102 is attached to the base of the finger in this way, the cable 101 can be short and the cable 101 does not interfere with the runner during running. Also, when measuring the distribution of body temperature from the palm to the fingertip, it is known that the temperature at the fingertip decreases significantly when the ambient temperature is low, whereas the temperature at the base of the finger does not decrease relatively. Has been. Therefore, at the base of the finger, the sensor unit 102
By wearing, even when running outdoors on a cold day, it is possible to accurately measure the pulse rate and the like.

On the other hand, on the front side of the wristwatch at 6 o'clock,
A connector section 105 is provided. This connector part 1
A connector piece 106 provided at the end of the cable 101 is detachably attached to the cable 05, and by removing the connector piece 106 from the connector portion 105, this device can be used as an ordinary wrist watch or a stopwatch. . For the purpose of protecting the connector portion 105, a predetermined connector cover is attached when the cable 101 and the sensor unit 102 are removed from the connector portion 105. As the connector cover, a component having the same configuration as that of the connector piece 106 except for an electrode portion and the like is used.

According to the thus constructed connector structure, the connector portion 105 is arranged on the front side as seen from the user, and the operation becomes simple if the runner is used. Further, since the connector portion 105 does not project from the device main body 100 in the 3 o'clock direction of the wristwatch, the runner can freely move his / her wrist during running, and even if the runner falls down during running, the back of the hand is Does not hit the connector section 105.

The other parts in FIG. 3 will be described in detail below with reference to FIG. FIG. 4 shows the details of the apparatus main body 100 in this embodiment.
It is shown with the cable 101 and the wristband 103 removed. Here, in the figure, the same parts as those in FIG. 3 are designated by the same reference numerals, and the description thereof will be omitted here.

In this figure, the apparatus body 100 is equipped with a watch case 107 made of resin. Watch case 107
A liquid crystal display device 108 for digitally displaying pulse wave information such as the pulse rate in addition to the current time and date is provided on the surface of the. The liquid crystal display device 108 includes a first segment display area 108-1 located on the upper left side of the display surface,
The second segment area 108-2 located on the upper right side, the third segment area 108-3 located on the lower right side, and the dot display area 108-D located on the lower left side.

Here, the date, day of the week, current time, etc. are displayed in the first segment area 108-1. Further, in the second segment area 108-2, elapsed time and the like are displayed when various time measurements are performed. In the third segment area 108-3, the pulse rate measured in the pulse wave measurement, the target value / actual measurement value of the variation point HRtp, etc. are displayed. Further, various kinds of information can be graphically displayed in the dot display area 108-D, and a mode display showing what mode the present apparatus is in at a certain point of time, a relationship between the lap and the pulse rate Various displays are possible, such as a graph showing the, and a bar graph display of the temporal change of the pulse rate. In addition, in the above mode,
In addition to the original mode used as a training support device, there are a mode for setting time and date, a mode for use as a stopwatch, a mode for setting a mutation point HRtp, and the like.

On the other hand, inside the watch case 107, a control unit 109 for carrying out signal processing for displaying changes in the pulse rate on the liquid crystal display device 108 is built in. The control unit 109 includes a clock circuit for clocking, and the liquid crystal display device 108 displays not only a normal time display but also a lap time, a split time, and the like in a mode operating as a stopwatch. It

On the other hand, button switches 111 to 117 are provided on the outer peripheral portion and the surface portion of the watch case 107. When the button switch 111 in the 2 o'clock direction of the wristwatch is pressed, an alarm sound is generated when one hour has elapsed from the time when the button was pressed. The button switch 112 in the 4 o'clock position of the wristwatch is for instructing the switching of various modes of the present device.

When the button switch 113 located at 11:00 on the wristwatch is pressed, the EL (Electro
Luminescence) The backlight lights up for 3 seconds,
After that, it goes out automatically. Further, the button switch 114 in the 8 o'clock direction of the wristwatch is for the dot display area 10
This is for switching the type of graphic display to be displayed on 8-D. In the mode for correcting the time, date, target value of the variation point HRtp, etc. by pressing the button switch 115 at the 7 o'clock position of the wristwatch,
It is possible to switch between display of hour / minute / second, year / month / day, 12/24 hour display, and setting of the target value of the variation point HRtp.

The button switch 116 located below the liquid crystal display device 108 has the above-mentioned time, date, and change point HRt.
It is used to decrement the set value by one in correcting the target value of p. Also, this button switch 116
Is also used as a switch for teaching the CPU 1 that the runner has passed the starting point of each lap during training.

The button switch 117 located on the upper side of the liquid crystal display device 108 is used to give an instruction to start / stop the operation of the training support device. In addition, the button switch 117 is
In addition to being used to increment the set value by 1 in the correction mode of the target value of the date and variation point HRtp, it is also used to instruct start / stop of various elapsed time measurements. A button type battery 118 built in the watch case 107 is prepared as a power source of the present device. The cable 101 shown in FIG. Unit 10
It plays the role of sending the detection result of No. 2 to the control unit 109.

Further, in the present apparatus, it is necessary to increase the size of the apparatus main body 100 as the functions provided in the apparatus are increased. However, due to the restriction that the device body 100 is worn on the wrist, the device body 100 cannot be expanded in the 6 o'clock direction and 12 o'clock direction of the wristwatch. Therefore, in this aspect, the length dimensions in the 3 o'clock direction and 9 o'clock direction of the wristwatch are 6 o'clock and 12 o'clock.
A horizontally long watch case 107 longer than the length in the time direction is used.

Further, in this embodiment, the wristband 103 is connected to the watch case 107 at a position biased toward the 3 o'clock side. Further, when viewed from the wristband 103, there is a large overhanging portion 119 in the 9 o'clock direction of the wristwatch, but such a large overhanging portion does not exist in the 3 o'clock direction of the wristwatch. Therefore, instead of using the horizontally long watch case 107, the runner can bend his / her wrist and the back of the hand does not hit the watch case 107 even if the runner falls.

Further, inside the watch case 107, a flat piezoelectric element 120 used as a buzzer is arranged at 9 o'clock with respect to the battery 118. Here, the battery 11
8 is heavier than the piezoelectric element 120, and the position of the center of gravity of the apparatus main body 100 is biased in the 3 o'clock direction. However,
Since the wristband 103 is connected to the side where the center of gravity is biased, the device body 100 can be worn on the arm in a stable state. Further, the battery 118 and the piezoelectric element 1
Since 20 and 20 are arranged in the surface direction, the device main body 100 can be made thin, and the runner can easily replace the battery 118 by providing the battery cover on the back surface of the wristwatch.

It should be noted that the control unit 109 of FIG. 4 corresponds to the CPU 1 and the ROM of FIG. 1 in correspondence with FIG. 1 and FIGS.
2, RAM 3, sensor interface 6, display control circuit 8, and clock circuit 9. Further, the sensor unit 102 of FIG. 3 corresponds to the pulse wave detection unit 4 of FIG. 1, and the liquid crystal display device 108 of FIGS. 3 to 4 corresponds to the display device 7 of FIG. Furthermore, the button switches 111 to 1 of FIGS.
Reference numeral 17 corresponds to the operation unit 10 in FIG. Further, in this aspect, the pulse wave is measured at the base of the finger of the runner's hand. However, the measurement site of the pulse wave is not limited to this, and for example, the pulse wave may be measured at the radial artery part or its peripheral part.

Next, the operation of the training support device having the above configuration will be described. In the following description, lap speed increase type training is assumed. That is, the runner is supposed to perform training by going around a course of a predetermined distance, and further, the running speed is gradually increased as the running is repeated. In addition, to simplify the explanation, it is assumed that one course of the course is one kilometer.

First, when starting training, the runner presses the button switch 117 of the wristwatch to activate the training support device. The CPU 1 recognizes the pressing of this button via the operation unit 10, and
Of the work area provided on the liquid crystal display device 10
8. Initialization processing such as screen deletion on 8 is executed to prepare for the subsequent measurement.

Next, the runner depresses the button switch 116 of the wristwatch to start with a relatively slow speed (for example,
Start running with the goal of 270 seconds / km). Pressing this button causes the CPU 1 to read the time from the clock circuit 9 and store it in the RAM 3 as the start time of the revolution in order to measure the time required for the first revolution. Next, the CPU 1
The pulse wave waveform detected by the pulse wave detector 4 is read for a predetermined time via the sensor interface 6, the pulse rate is calculated based on these waveforms, and the calculation result is stored in the RAM 3. During the training, the CPU 1 continuously performs this pulse rate calculation process, and sequentially accumulates the measured pulse rate in the RAM 3.

After that, when the runner finishes the first round, the runner depresses the button switch 116 again. By depressing this button, the CPU 1 determines that the first round has been completed, and the time when the button is pushed is read from the clock circuit 9 and stored in the RAM 3. This time is the end time of the first lap and the start time of the second lap.

Next, the CPU 1 obtains the difference between the start time and the end time of the first lap and sets it as the runner's lap in the lap. It should be noted that although the lap is used here, the traveling speed may be calculated. In that case, the traveling speed is calculated with reference to the distance of one round of the course. The distance of one round may be measured by walking on the course with a pedometer or the like, and set in the apparatus using the button switches 112, 115 to 117.

Further, the CPU 1 reads all the pulse rates measured in the first round from the RAM 3 and selects the maximum pulse rate (for example, 100 beats / minute) from these pulse rates. Then, the above-described circuit lap and maximum pulse rate are stored in the RAM 3, and these data are converted into coordinate values on the display device 7 and sent to the display control circuit 8. As a result, the measurement point of the first orbit is displayed on the display device 7.
It is plotted on the graph displayed in (dot display area 108-D of the liquid crystal display device 108). The state of this plot is shown in FIG. 5, and the point P1 in the figure corresponds to the measurement point of the first round.

Next, the runner raises the lap a little more than the first lap (for example, 260 seconds / km) and runs the second lap. The CPU 1 measures the pulse rate and calculates the traveling time required for the second lap in accordance with the same procedure as the first lap. Then, the measurement point of the orbit is plotted on the graph as point P2 in FIG.
In this way, the runner gradually trains by increasing the orbital lap as he or she repeats, and along with this, the CPU 1 sequentially plots the maximum pulse rate and the orbital lap in each lap on the graph (points in FIG. 5). P3, P4,
(See P5, ...).

Further, the CPU 1 performs the following processing in the third and subsequent rounds. Here, as an example, 9
The processing at the end of the round of the lap will be described, but the processing in other rounds is exactly the same. As described above, the CPU 1 stores the maximum pulse rate and the lap in each lap in the RAM 3. So, CPU
In No. 1, the maximum pulse rate and the orbital lap measured during the 1st to 8th orbits are read from the RAM 3, and the well-known "least square method" is applied to these data. That is, at each measurement point, the residual sum of squares of the pulse rate and the orbital lap is minimized, and the pulse rate-to-orbital lap line that best fits these measurement points is determined.

Next, the measurement point P9 on the ninth orbit
Is calculated from the calculated straight line. And
If this deviation exceeds the predetermined value, the immediately preceding measurement point (here, point P8) is determined as the variation point HRtp. And
The plot is changed from the ● mark to the □ mark to clearly show that this measurement point is the mutation point HRtp. In this way, the runner can visually confirm the mutation point HRtp on that day. After that, the runner continues to orbit while watching the graph on the dot display area 108-D of the liquid crystal display device 108, and finishes the training when it becomes clear that the increase in the pulse rate has reached the peak.

By the way, the mutation point H obtained as described above
Rtp is unique to each runner, but is not always normal in consideration of the physical condition of the runner on the measurement day. Therefore, the above-mentioned mutation point HRtp
Is carried out for several days, and the average of them is taken to determine the mutation point HRtp in normal times. The mutation point HRtp thus obtained is
In subsequent training, it can be used as a target value for training. Therefore, the operation of the present apparatus when the target value is set will be described below.

First, before the start of training, the runner operates the button switch 112 to set the correction mode of the set value, and selects the "setting of the target value of the variation point HRtp" by the button switch 115. And button switch 1
16 and 117 are manipulated to adjust the target value of the mutation point HRtp to the value obtained as described above. As a result, the CPU 1 stores the input target value in the RAM 3. Further, the CPU 1 plots the target value (for example, the mark ■ in the figure) at the corresponding position in the graph of FIG. 5 so that the runner can visually recognize the target value of the variation point HRtp.

As a result, the runner refers to the displayed plot of the target value of the changing point HRtp and refers to how many laps the Runner has to reach to the changing point HRtp. You can make a plan such as whether or not you should raise the lap.
For example, if you feel that you are in good shape, you can plan to reach your target with a few laps, or you can take more laps than usual and bring it to your target. You can also do so.

Next, the runner presses the button switch 117 of the wristwatch to activate the training support device,
Training is performed while pressing the button switch 116 for each lap. Then, according to the same procedure as described above, a plot is made on the graph for each revolution, and it is determined whether or not the variation point HRtp is reached each time the revolution is completed. Then, the mutation point HRtp (Fig. 5
When the □ mark and the point P8) are detected, the CPU 1 reads from the RAM 3 the pulse rate and the orbit lap related to the target value (marked in FIG. 5) set before the start of training, and relates to the mutation point HRtp just obtained. Compare with pulse rate and lap.

As a result, when either the pulse rate or the difference in the orthographic lap (or both may be exceeded) exceeds the predetermined range, the CPU 1 displays a message to that effect on the display device 7 to warn the runner. I do. For example, FIG.
In the case of, the □ mark is clearly less than the ■ mark,
It indicates that he is not feeling well. The CPU 1 may give a warning by blinking a plot of the measured mutation point HRtp (marked by □ in FIG. 5).

As described above, if the target value of the variation point HRtp is set, this device can determine the physical condition of the runner of the day and issue a warning to the runner, and an abnormal physical condition can be detected early. It becomes possible to do. In addition, as described above, if you perform intense training, the mutation point H
Since Rtp increases, if it is known that the mutation point HRtp increases, the runner can objectively understand that the training is successful.

In the above embodiment, the mutation point HRtp
Although the value itself is set as the target value, in ordinary training, a value at a level slightly above the mutation point HRtp is often set as the target value for training in order to improve the effect. Therefore, the mutation point H
A value slightly higher than Rtp may be set as the target value and this value may be displayed. Furthermore, the target value may be changed according to the physical condition of each runner (that is, the measurement result of the variation point HRtp at that time), and the target value may be notified to the runner.

Further, in the above embodiment, the maximum pulse rate within the lap was used for plotting the measurement points in each lap, but the present invention is not limited to this, and for example,
You may use the average value of the measured pulse rate. Further, when plotting the points representing the lap lap and the pulse rate on the graph, the values of the lap lap and the pulse rate of each plot may be displayed, and the variation point HRtp or the pulse rate and the lap of the target value may be displayed. May be displayed.

Although the warning to the runner is given by using the display device 7, the warning may be given by sound by diverting the existing alarm function built in the wristwatch. Although a wristwatch has been taken as an example of the mobile device, the present invention is not limited to this, and there is no problem even if it is incorporated into another mobile device.

[0054]

As described above, according to the invention described in claim 1, the pulse wave of the runner is detected, the pulse rate is determined for each lap of training, and based on the lap instruction of the wearer. Since the lap lap is calculated for each lap and the relationship between the pulse rate and the lap is notified to the wearer, the wearer does the lap in each lap as expected when performing the lap climb type training. The effect is that it is possible to accurately grasp whether or not the pulse rate has been achieved and whether the pulse rate is appropriate.

According to the second aspect of the invention, at the end of each lap, the pulse rate and the lap in the lap are predicted from the measured values of the pulse rate and the lap in the last lap, and the prediction is made. It detects that the deviation between the measured value and the measured value in the lap exceeds a predetermined value, and notifies the wearer of the mutation point where the relationship between the pulse rate and the lap is changed. The effect that the mutation point HRtp, which is an important index for performing the above, can be easily known is obtained.

According to the third aspect of the invention, the least squares method is applied to the pulse rate and the lap lap up to the immediately preceding lap so that the predicted values of the pulse rate and the lap lap in the lap are calculated. Therefore, it is possible to obtain the effect that the obtained predicted value can be a very good estimation amount of the pulse rate and the lap in the lap.

Further, according to the invention of claim 4, the preset target value of the variation point is compared with the actually measured value, and if the difference between them exceeds a predetermined value, a warning is given to the wearer. As a result, if it is found that the physical condition of the wearer has changed from the normal state, the effect can be obtained by promptly notifying the wearer of this change and calling attention. .
