Description

  The present invention relates to an exercise load test apparatus composed of an ergometer or the like used for an exercise load test performed in a hospital or health promotion facility, and more particularly to display of a subject's state including the subject's exercise state and body state.

  Conventionally, the display form of the display unit in exercise equipment that performs training and physical fitness measurement has been improved, and the state of the athlete such as the pulse rate and pedal rotation speed has been detected. In order to notify the person surely, an exercise load is given to the exerciser according to the set exercise program, and the pulse rate and pedal rotation speed of the exerciser are detected. When it exceeds the range, the pulse rate display part or the rotation speed display part blinks, and when this state continues for a predetermined time, an error notification sound is output and the exercise program is stopped and the system proceeds to cooling down ( (See Patent Document 1).

  Further, regarding the display, the display of the display board indicated by the pointer is shared by the low-speed display area and the high-speed display area, and the vehicle speedometer is arranged with numbers indicating numerical values corresponding to each area, the speedometer The comparison means for outputting the switching signal by comparing the detection output of the speed sensor between the low speed region and the high speed region, and the measurement range of the movement for driving the pointer according to the switching signal from the comparison means is low speed A first switching means for switching to the high-speed side or a high-speed side, and a second display for displaying one of the numbers corresponding to the measurement range and extinguishing the other according to the switching signal of the comparison means There is one comprising switching means (see Patent Document 2).

  Also, with regard to an ergometer that is a general exercise load test device, load accuracy was guaranteed only under a certain speed condition, so it was necessary to move at that speed, but load accuracy was guaranteed regardless of speed. With the advent of an ergometer, it is possible to instruct pedaling speed during exercise according to the physical strength and exercise ability of the exerciser.

Japanese Patent Laid-Open No. 11-128397 JP-A-1-96559

  When performing an exercise load test using such an exercise load test apparatus, in order to obtain a more accurate test, the subject often performs a pedaling operation at a predetermined speed, and therefore an ergometer. The subject is exercising while looking at the speedometer, which is a display unit mounted on the. However, in an ergometer that has only a speedometer that displays the speed only in a predetermined unique speed range, when the pedaling speed instruction at the time of exercise is changed due to the difference in physical strength or exercise capacity of the person who exercises, that is, the subject, There was a problem that the shake position of the speedometer changed and it was difficult to see. In addition, there is a problem that it is difficult to easily recognize that the user is exercising at an excessive speed or conversely at a slow pace.

  Moreover, the above problem cannot be solved by simply switching the display area between the low-speed display area and the high-speed display area as in the prior art.

  Furthermore, if the non-experimenter is displayed as to whether the exercise state or physical condition is appropriate, and if an alarm blinking display is made when it is exceeded, the awareness of the appropriate level becomes too high and psychological stress increases. As a result, the heart rate and blood pressure increase due to factors other than exercise, and an appropriate exercise load test cannot be performed.

  In the exercise load testing apparatus such as an ergometer, the present invention does not display the detected value such as the rotation speed of the rowing pedal on the display unit by a predetermined unique conversion, but can change the conversion formula or coefficient. It is an object of the present invention to provide an exercise load test apparatus capable of shifting the detection value range displayed on the display area by the display unit.

  The present invention is an exercise load test apparatus that applies exercise load to a subject and displays the state of the subject at that time on a display unit, the display unit having an analog display region, and the state of the subject detected by the subject state detection unit The subject state signal indicating the subject state signal value is displayed in analog on the display unit, and the range of the subject state signal value displayed in the analog display area of the display unit is shifted according to the input subject motion level and displayed. There is provided an exercise load testing apparatus characterized by comprising display control means for converting to a display signal and inputting the display signal to the display unit to display a subject state.

  According to the present invention, it is possible to provide an exercise load test apparatus in which each subject having different physical strength can easily see the subject state including his / her exercise state and body state.

  In the exercise load testing device according to the present invention, when the rotation speed of the rowing pedal is displayed as the state of the subject, for example, an analog display (for example, the portion indicating the value in the display area is predetermined as the value increases or decreases). The rotational speed range displayed in the analog display area of the display unit that performs the display along the direction of (2) is 20 rpm to 60 rpm when level 1 is input as the subject exercise level, and level 2 When is input, the shift is performed so as to be 40 rpm to 80 rpm.

  When the rotation speed of the rowing pedal is displayed in an analog manner, the above-mentioned level 1 is used for an elderly person who does not have physical strength and cannot be pedaled very fast, and the above-mentioned level 2 is used for a healthy adult. When the pedaling is performed, the indicator needle of the speedometer serving as the display unit can be exactly pointed to the middle of the display area, so that each subject can take an exercise load test in a state where the display result is easy to see. Also, when used in this way, the subject only needs to perform pedaling exercise so that the display instruction is always exactly in the middle of the display area of the display unit, which is easy to understand.

  In addition, the position of the pointer on the display unit is not restrictive, and it can be instructed to the subject as a target having a weak restraining force, and it is difficult for the pulse and blood pressure to increase due to psychological effects.

Embodiment 1 FIG.
1 is a diagram showing a configuration of an exercise load testing apparatus according to Embodiment 1 of the present invention. FIG. 1 shows an example in which the display unit 6 is composed of a speedometer 6a that performs linear analog display using a movable iron piece type voltmeter and a DA converter 6b. The rowing pedal 98 that gives an exercise load to the subject includes a pedal 9 and a motor 8 that gives a load to the pedal 9. The load of the motor 8 is controlled by the load control unit 7. The rotational speed of the pedal 9 is detected by the rotational speed detector 1, and the detected rotational speed signal, which is a subject state signal, is taken into the CPU 2 including the display control means, which is a control unit of the exercise load test apparatus. The CPU 2 operates according to a built-in program, for example.

  An input for setting the exercise load test apparatus by the subject is performed from the keyboard 10 which is an input unit, and in particular, the above-described subject exercise level indicating the exercise ability of the subject is inputted here. The memory 4 includes a signal conversion formula 4a for converting a rotation speed signal from the rotation speed detector 1 serving as a subject state detection unit into a display signal for analog display on the display unit 6 (speedometer 6a), and a display unit 6 A subject movement level / display shift coefficient table 4b for obtaining a display shift coefficient for shifting so that the range of the rotation speed signal value displayed in the analog display area is in a range according to the subject movement level from the keyboard 10. Storing.

  In the CPU 2, the signal conversion formula 4 a stored in the memory 4 and the subject motion level / display shift coefficient table 4 b stored in the memory 4 are obtained with respect to the subject motion level input from the keyboard 10. Based on the display shift coefficient, the rotational speed signal detected by the rotational speed detector 1 is converted into a display signal, which is input to the DA converter 6b.

Here, when the rotation speed signal value is RS, the display signal value is DP, the signal conversion formula is f (RS), and the display shift coefficient is K, these are expressed by the following formula (1).
DP = f (RS) + K (1)

  In the DA converter 6b, the digital display signal from the CPU 2 is converted into an analog display signal composed of, for example, a voltage signal and input to the display unit 6. In the display unit 6, when a voltage according to the display signal value of the input analog display signal is applied to the coil (not shown), a current proportional to the coil flows through the coil, for example, by a permanent magnet around the coil. An electromagnetic force acts between the generated magnetic field and the coil current, the coil rotates in proportion to the magnitude of the current, and the indicator needle fixed to the coil swings to display the rotation speed.

  If the range of the rotational speed signal value displayed in the analog display area of the speedometer 6a of the display unit 6 at this time is shifted by the above-described display shift coefficient, and the subject motion level from the keyboard 10 is level 1, for example, 20 rpm ~ 60rpm, Level 2 is 40rpm ~ 80rpm. When pedaling at the center value of 40rpm and 60rpm respectively, the indicator needle can be just pointing to the middle of the display area, so that each subject can easily see the display result. It is possible to take an exercise load test, and it is easy for the subject to perform pedaling exercise so that the display instruction is always in the middle of the display area of the display unit.

Embodiment 2. FIG.
FIG. 2 is a diagram showing a configuration of an exercise load test apparatus according to Embodiment 2 of the present invention. FIG. 2 shows an example in which the display unit 11 includes a plurality of LED segments 11a to 11e and an output port 11f for supplying a lighting signal to each of the LED segments 11a to 11e. The other parts are basically the same as those in FIG.

  As in the first embodiment, the rotation speed signal captured by the CPU 2 is subject motion input from the keyboard 10 based on the signal conversion formula 4a stored in the memory 4 and the subject motion level / display shift coefficient table 4b. A display shift coefficient determined according to the level is converted into a display signal having a value based on the above equation (1) and input to the output port 11f. The output port 11f supplies a lighting signal for lighting the LED segments 11a to 11e according to the input display signal value.

  As a display method, for example, the range of the rotational speed signal value displayed in the linear analog display area composed of the plurality of LED segments 11a to 11e of the display unit 11 is set to 20 rpm to 60 rpm when the subject motion level is 1, and the subject motion level 2 When shifting to 40 rpm to 80 rpm at the time of the test, when the subject motion level is 1, the LED segment 11a is turned on when the rotation speed signal value is 20 rpm or more, the LED segment 11b is turned on at 30 rpm or more, and every time 10 rpm is increased thereafter. The LED segments 11c to 11e are sequentially turned on. When the subject movement level is 2, the range of the rotation speed signal value is set to 40 rpm to 80 rpm and the display is turned on in the same manner.

  As described above, the same effect as the above embodiment can be obtained.

  In each of the above-described embodiments, the example in which the rotation speed detector 1 is used as the subject state detection unit that detects the subject state including the subject's motion state and body state is shown, but the present invention is limited to this. However, instead of the rotation speed detector 1, for example, a heart rate detector for detecting the heart rate of the subject shown in FIG. 1 and FIG. In these cases, the heart rate and muscle activity of the subject are displayed on the display unit, and the same effect as described above can be obtained.

  As a characteristic display example, the limit value a of the subject state (exercise state and body state) such as the rotation speed for each subject exercise level from the keyboard 10 is previously set as, for example, the subject exercise level / display shift table 4c in the memory 4. Store it. Then, for example, each display position in the analog display area of the display unit 6 and a value in the display area are set as shown in FIG. The set value of the minimum position A (left end in FIG. 3) of the analog display area is variable, and the maximum position B (right end in FIG. 3) is set to the limit value a of the subject state with respect to the subject motion level. The entire analog display area and the center position C1 of the target area C are set to a target value c1 (c1 = a × 0.5) at a first predetermined ratio (for example, 50%) with respect to the limit value a. Then, the minimum position C2 and the maximum position C3 of the target area C are obtained by adding a value α (α = a × 0.2) of a second predetermined ratio (for example, 20%) to the limit value a to the target value c1. c2, c3 (c2 = c1-α, c3 = c1 + α).

  The first and second ratios may be set in advance in the internal memory of the CPU 2 or may be stored in the subject exercise level / display shift table 4 c in the memory 4 in advance.

  The CPU 2 sets the above c1 to c3 based on the limit value a of the subject exercise level / display shift table 4c in the memory 4 and the first and second ratios with respect to the inputted subject exercise level, and a, c1 Based on the analog display area defined by c3, signal conversion is performed and a display signal is output. As a result, the desired value c1 serving as the center position of the analog display area and the width (from c2 to c3) of the target area C having the target value c1 as the center position C1 are set to a desired ratio of the limit value a to the subject movement level. The display can be performed in the analog display area determined in (1).

  It should be noted that the first and second ratios can be set to desired values, respectively, or may be common to all the subject exercise levels or may be set separately.

  The exercise load testing apparatus according to the present invention is expected to be used in the field of fitness centers for the purpose of promoting health and in the medical field for exercise therapy and cardiopulmonary endurance testing.
