Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for measuring the physical strength of an exerciser by changing the exercise load of the exerciser in a plurality of stages.

[0002]

2. Description of the Related Art Conventionally, a load test has been performed as necessary as one item of physical strength measurement. Generally, a load test is
The degree of cardiopulmonary endurance is determined, for example, by performing a constant knee extension / contraction exercise and comparing the subsequent pulse fluctuation with the pulse rate at rest. Generally, it is considered that the lower the rate of increase of the pulse rate with the increase in the exercise load, the higher the cardiorespiratory endurance.

The characteristics of the change of the pulse rate with respect to the change of the exercise load (hereinafter referred to as "load value-pulse rate characteristics").
When performing physical strength measurement, the user can continuously expand and contract the knee by rotating the foot pedal, and set the exercise load by changing the weight of the pedal (the load on the pedal). Exercise equipment is used.

[0004] Japanese Patent Publication No. 1-46944 discloses a method for measuring physical strength using such an exercise device.
According to this method, a general expression of a straight line indicating a load value-pulse rate characteristic is obtained based on age-specific data obtained by statistics, and a load value to be increased stepwise is determined based on the straight line.
When setting the load value, a predetermined initial load value is first set, the pulse rate at the initial load value is measured, and the value is statistically obtained at the initial load value on the load value-pulse rate characteristic line. By comparing with the pulse rate, it is determined whether the athlete is a high physical fitness person or a low physical fitness person, and the load value of the second stage is statistically determined accordingly. Are set based on the respective load value-pulse rate characteristic straight lines, and the pulse rate at the load value is measured. Similarly, the pulse rate at the load value in the third stage is measured, and the load value-pulse rate characteristic is obtained based on the three load values and the pulse rate.

FIG. 12 and FIG. 13 show examples. FIG.
2 shows examples of changes in the load value and the pulse rate at each stage for the four types of exercisers. FIG. 13 shows a procedure for setting a load value at each stage. First, the first
The load value was set to 25 W in the step, and the pulse rate HR at that time was measured.
Set watts, second for those with HR over 90
Set 50 watts in stages. Subsequently, the pulse rate HR in the second step is measured, and for a person whose pulse rate HR is 110 or less when a load value of 65 W is set in the second step, 1 is set in the third step.
05W is set, and for a person whose HR exceeds 110, 80W is set in the third stage. In the second stage, the load value 5
If the pulse rate HR of a person who sets 0 W is 120 or less,
The load value is set to 75 W in the stage, and the person whose HR exceeds 120 sets the load value to 65 W in the third stage. Then, a load value-pulse rate characteristic as shown in FIG. 12 is obtained based on the load value and the pulse rate at each stage.

In a conventional training apparatus having a physical strength measurement function, a load value of the third stage is set by dividing the load values of the first and second stages into three classes, respectively. Was. An example is shown in FIG. In the figure, the horizontal axis indicates the load value (torque value), and the vertical axis indicates the pulse rate. First, the load value is set to 1.0 kg in the first step, and the load in the second step is determined according to the pulse rate at that time. Value 1.2
kg, 1.8 kg, or 2.5 kg, and the load values in the third stage are individually set according to the pulse rate classification in the second stage.

[0007]

However, in such a conventional exercise load (hereinafter simply referred to as load) setting method, the load in the next stage is determined only from the absolute value of the pulse rate measured in each stage. The relative change (history) between the load and the pulse rate obtained up to the previous stage is not considered at all. For example, a person with a larger relative change (increase) in the pulse rate when the load is increased from a relatively low load state is generally considered to be a low fitness person. The absolute value of the pulse rate under the load state alone cannot reliably discriminate between the low physical strength person and the high physical strength person. For example, in FIG. 15, the load value-pulse rate characteristic line L1
In the case of the exerciser indicated by, the pulse rate in the first stage (load value 25 W) falls into the class of the low-strength person side, but the pulse rate rise value from the first stage to the second stage (load value 50 W) Despite the fact that he entered the class for the low-strength person in the first stage despite the fact that he was small (considered to be relatively physically strong), the load value was set to 50 W in the second stage and the load was Value is 75
W is set. For this reason, a load value-pulse rate characteristic straight line is obtained at three points in which the load value is biased to a small value despite the fact that the exerciser has relatively physical strength.
A reliable load value-pulse rate characteristic cannot be obtained. In this case, if some of the load values shown in the figure are used, a three-stage load as indicated by a triangle should be given. Also,
In the case of an exerciser having a load value-pulse rate characteristic indicated by L2,
The pulse rate in the first stage (load value 25 W) falls into the class of the high-strength person side, but from the first stage to the second stage (load value 65 W)
Despite a large increase in the pulse rate to the person (considered to be relatively infirm), he entered the class of the high fitness person in the first stage, so the load value was set to 65 W in the second stage Then, the load value is set to 80 W in the third stage. For this reason, even though the exerciser has relatively little physical strength, an excessively large load is applied unnecessarily, which places a burden on the exerciser. In this case, if some of the load values shown in the figure are used, the three-stage load indicated by the squares should be given.

[0008] In the conventional exercise load setting method,
Resting pulse rate and rise from resting pulse rate are not considered at all. For example, in the case of the exerciser indicated by the load value-pulse rate characteristic line L1 in FIG. 15, the pulse rate at rest (the pulse rate at no load) is relatively high, but the pulse rate at the load value of 25W in the first stage is relatively high. In spite of the small increase in the number (it is considered to be relatively strong), the pulse rate in the first stage falls into the class of the low fitness person side, so the load value is set to 50 W in the second stage. You. Therefore, a straight line of the load value-pulse rate characteristic is obtained at a point where the load value is biased toward a small value. In the case of an exerciser having a load value-pulse rate characteristic indicated by L2, the pulse rate at rest is small, but the rate of increase up to the pulse rate in the first stage is high (for those who are classified as low physical fitness persons). Despite this, the pulse rate in the first stage is divided into smaller ones, and the load value is set to 65 W in the second stage. Therefore, a large load is suddenly applied to the exerciser even though the exerciser has relatively little physical strength.

An object of the present invention is to take into account the relative changes (history) between the exercise load and the pulse rate when the exercise load changes, when measuring the physical strength of the exerciser while changing the exercise load in a plurality of stages. An object of the present invention is to provide a physical strength measuring device and a physical strength measuring method which solve the above-mentioned problems.

[0010]

A physical strength measuring device and a physical strength measuring method according to the present invention detect a pulse of an exerciser with a pulse sensor, and measure a pulse rate of the exerciser based on an output of the pulse sensor. Estimate the load value of the exerciser-pulse rate characteristics based on the pulse load measured at the exercise load value of each stage and each exercise load value, set the exercise load value at any stage according to the estimation result, An exercise load corresponding to the exercise load value is given to the exerciser. As described above, after estimating the exercise load-pulse rate characteristics of the exerciser based on the pulse rate at a plurality of stages with different exercise loads, the exercise load value at any other stage is set. Unlike the case where the load of the next stage is determined based on the absolute value of the pulse rate at each load stage as described above, an appropriate load more suitable for the physical strength of the exerciser can be given.

Further, the physical strength measuring device and the physical strength measuring method of the present invention determine a target pulse rate to be reached at a predetermined stage from at least physical data of the exerciser, and obtain a target exercise load value corresponding to the target pulse rate. The load value-pulse rate characteristic is estimated from the exercise load values of the two stages having relatively small exercise load values and the pulse rate at each exercise load value, and the relative exercise load value is estimated in accordance with the estimation result. Exercise load values of an extremely large stage are set to be substantially equally spaced within the target exercise load value. Thus, the load value-pulse rate characteristic can be obtained with higher accuracy without biasing the distribution of points on the straight line indicating the load value-pulse rate characteristic.

[0012] Moreover, even if the physical strength of the exerciser is different,
Since the load is always applied only to the load corresponding to the target pulse rate, the physical strength can be measured under the same exercise intensity for each exerciser regardless of the exerciser.

Further, the physical strength measuring apparatus and the physical strength measuring method of the present invention set one of the exercise load values of the two stages having relatively small exercise load values to no load, that is, the resting pulse rate is also reduced. By using this, a change in the pulse rate can be recognized when the load is first applied, and the load value in the subsequent stages can be set accurately.

In the physical strength measuring apparatus and the physical strength measuring method according to the present invention, the exercise load values in two stages, which are relatively small, are determined based on the physical data of the exerciser. For example, first, the resting pulse rate is measured, and when the load is gradually increased from a light load, the first load applied to the exerciser is determined based on the physical data of the exerciser. Thus, at the stage where the load value-pulse rate characteristic has not yet been determined, by determining the load value based on the physical data of the exerciser, the pulse rate at rest and the pulse rate at rest with this load applied are determined. Is obtained appropriately.

Further, the physical strength measuring device and the physical strength measuring method of the present invention detect the pulse rate in the exercise load state at that time based on the pulse sensor output before a predetermined time when the exercise load changes. Thereby, the pulse rate in a state where the pulse is stabilized after the exercise load is changed and before the next exercise load is changed can be reliably obtained.

Also, the motorcycle training apparatus of the present invention includes the physical strength measuring device and a foot pedal, and the exercise load means applies the exercise load set by the exercise load setting means to the foot pedal. This makes it possible to easily measure physical strength using the motorcycle training device.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A configuration of a training apparatus having a physical strength measuring function according to an embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is an external view of a motorcycle training apparatus (hereinafter simply referred to as a "training apparatus"). This device partially imitates the form of a bicycle (motorbike), and includes a saddle 10, a foot pedal 11, a handle 12
Are connected in a substantially V-shape, and the exerciser is seated on the saddle 10,
Training and physical strength measurement can be performed by holding the handle 12 with the hand and rotating the foot pedal 11 with the foot. The load applied to the pedal 11 changes during execution of the physical strength measurement mode.

The operation panel 1 is located between the left and right handles 12.
3 is provided so that the operation panel 13 can be easily seen while the exerciser is exercising.

FIG. 2 is a plan view of the operation panel 13.
The operation panel 13 has a display section 20 at the center in the front of the panel, a program input switch section 30 for selecting and inputting a training program on the right side, a personal data input switch section 40 for inputting personal data on the left side, and an exerciser. The exercise operation switch unit 50 which can be operated during the exercise is located in front of the user.

The program input switch section 30 includes switches for selecting and inputting each of the training programs of the physical strength measurement 31, weight loss 32, physical strength increase 33, manual 34, exercise lack elimination 35, and game 36. The personal data input switch section 40 has a personal number 41 and an age of 4.
2, a switch for inputting personal data of weight 43 and men and women 44 is provided. Among them, the switches of age 42, weight 43, and sex 44 are switches for inputting physical data. The exercise operation switch unit 50 arranged below the display unit 20 sequentially includes a pitch sound 51, a load increase / decrease 52, a start / stop 53, a calorie / distance / upper limit pulse rate from the left side when facing the operation panel 13. Display switching 54
Includes each switch. The switch of the pitch sound 51 is operated when the pitch sound is turned on or off during exercise, and the switch of the load increase / decrease 52 is operated when the exercise load is increased or decreased during training. The switch of the display changeover 54 switches the data displayed on the display unit 20 into calories, distance,
This switch is operated when switching to any of the upper limit pulse rates. The switch of the start / stop 53 is a switch operated when starting and stopping training and physical strength measurement. The power switch 60 is arranged on the upper left side of the operation panel 12.

FIG. 3 is a block diagram showing the configuration of the control unit of the training apparatus. In FIG.
0 is a CPU 111, a key switch 112, an LCD 11
3. It comprises a pulse measurement circuit 114, a buzzer 115 and a power supply circuit 116. The motorcycle unit 120 includes a pedal rotation speed detection sensor 121 and a load control unit 122. The photoelectric pulse sensor 102 is connected to the pulse measuring circuit 114 via a lead wire. The CPU 111 includes an arithmetic unit, a ROM in which a program is written, a RAM for storing various data when the program is executed, and an I / O port for inputting and outputting signals to and from an external circuit. As will be described later, the CPU 111
Is read, a display signal is output to the LCD 113, and a control signal is output to the load control unit 122. The CPU 111 reads the output signal of the pulse measurement circuit 114 to detect the pulse rate, and reads the output signal of the pedal rotation speed detection sensor 121 to detect the rotation speed of the pedal. The photoelectric pulse sensor 102 detects a photoelectric pulse wave across the earlobe, and the pulse measuring circuit 114 processes the detected signal, converts the signal into a logical level signal, and provides the logical level signal to the CPU 111. The buzzer 115 generates a pitch sound and various notification sounds. The power supply circuit 116 is a circuit for making a constant voltage using a dry battery as a power supply, and supplies a power supply voltage to each unit.

The pedal rotation speed detection sensor 121 is composed of, for example, a rotary encoder, and supplies a binary level signal, which changes with the rotation of the pedal, to the CPU 111. C
The PU 111 measures the rotation speed of the pedal by reading this signal at a predetermined cycle. The load control unit 122 is a device that controls the distance between the magnet arranged along the outer peripheral surface of the magnetic wheel that rotates with the rotation of the pedal and the outer peripheral surface of the wheel. An eddy current is generated in the wheel by the opposition of the magnet and the wheel, and a force acts in a direction that hinders the rotation of the wheel by the action of the magnetic force of the magnet. The distance between the magnet and the outer peripheral surface of the wheel is controlled by a pulse motor or a servomotor. The CPU 111 determines a distance between the magnet and the wheel by giving a control signal to the motor,
This controls the torque applied to the pedal when the pedal is at a predetermined rotation speed, and determines the exercise load (hereinafter simply referred to as “load”) applied to the exerciser.

FIG. 4 is a diagram showing the relationship between the exercise load and the pulse rate at each stage in the physical strength measurement mode, and FIG. 5 is a flowchart showing the processing procedure. First, age, weight, and gender are input as personal data, and a pulse rate measured in a resting state before pedaling is obtained as a resting pulse rate HR0 as shown in FIG. A load value W1 (fixed value) is set, and the pulse rate HR1 at that time is measured. When the load applied to the exerciser changes, the pulse rate gradually changes. As will be described later, the pulse rate (steady pulse rate) when the pulse rate of the exerciser stabilizes after the load on the exerciser changes. Measure.

Next, age and resting pulse rate (HR0)
, The target maximum pulse rate HR3 ′ in the final stage (third stage) is calculated. This means that the maximum pulse rate HRmax estimated from the age is obtained, and the target pulse rate HR3 'is set to HR
It is obtained as a ratio to max. Here, HR3 'is set to a value of 50% of HRmax. This maximum pulse rate HRm
ax is the maximum pulse rate for each individual, and is the pulse rate for the maximum oxygen uptake. This maximum pulse rate HRmax
Can be simply obtained at 220-age. Then, the target pulse rate HR of the third stage obtained in this manner is obtained.
3 ′ and the intermediate value (HR) between the steady pulse rate HR1 in the first stage.
A load value W2 corresponding to 2 ′) is obtained. That is, as shown in FIG. 4A, a straight line of a load value-pulse rate characteristic determined by the resting pulse rate HR0, the load value W1 in the first stage, and the steady pulse rate HR1 is obtained, and the equation of the straight line and HR2 are obtained. 'Is calculated from W ′. This means that the load value (W3) corresponding to HR3 'is obtained from a load value-pulse rate characteristic straight line, and
This is the same as obtaining an intermediate value between 1 and (W3) as W2.

Subsequently, the load value in the second stage is set to W2, and the actual steady pulse rate HR2 at that time is measured. Then, a regression line is obtained by the least squares method from the three-point load values and the pulse rate at rest and in the first and second stages, and a third regression line is obtained from the straight line and the pulse rate HR3 'to be targeted in the third stage. The stage load value W3 is calculated. Then, the load value is set to W3, and the actual steady pulse rate HR3 in that state is measured.
Then, as shown in FIG. 4C, the first, second, and third
A regression line is obtained again from each of the three load values and the steady pulse rate. This straight line is information representing the load value-pulse rate characteristics of the exerciser. Thereafter, if necessary, the maximum exercise load Wmax for the maximum pulse rate HRmax is calculated, and the maximum oxygen uptake VO ₂ max [ml / m
in].

[0027]

## EQU1 ## Wmax = (((VO ₂ max * 0.23) /0.01433)
* 5.047) / 1000 In the above example, the target pulse rate HR3 'is set to HRma
x, but the resting pulse rate HR0 and HRm
a value of a predetermined ratio with respect to ax may be obtained as the target pulse rate HR3 '. The equation for the case where the above predetermined ratio is 50% is as follows.

HR3 '= (HRmax-HR0) * 0.
5 + HR0 When the target pulse rate is determined in this manner, the ratio of W1 to W3 in the range from W1 to Wmax is constant regardless of the resting pulse rate, and the regression is performed with constant accuracy regardless of the individual difference of the exerciser. A straight line (load value-pulse rate characteristic straight line) is obtained.

FIG. 6 is a flowchart showing a procedure for measuring the pulse rate at rest. First, the rotation speed and pulse rate of the pedal are measured, and the passage of time is counted (n21). Subsequently, it is determined whether or not the measured pulse rate exceeds a predetermined upper limit pulse rate (n22). If the pulse rate does not exceed the predetermined upper limit pulse rate, an average pedal rotation speed Ravg is calculated. At the same time, it is determined whether the elapsed time exceeds 30 seconds and is 45 seconds or less (n23 → n24 → n25).
→ n26). If the elapsed time exceeds 30 seconds and is 45 seconds or less, it is determined whether the pulse rate is a predetermined abnormal pulse rate (n27). If the pulse rate is not abnormal, the average value of the pulse rate in 15 seconds from 30 seconds to 45 seconds is calculated as the resting pulse rate HR0 (n28). The pulse rate up to 30 seconds after the start of the measurement is not used as the measured value. As a result, the athlete straddles the saddle of the training device, puts his foot on the pedal, operates the operation panel, and waits for the user to be actually at rest.
Also, after the elapse of 45 seconds, the pulse rate tends to increase due to the sense of tension and sense of expectation that the setting of the load value in the first stage is performed. Do not use. If for any reason, for example,
When the driver suddenly steps on the pedal and the pulse rate increases, such as when the pulse rate exceeds a predetermined upper limit pulse rate, a notification sound is output to notify the user of the fact that the pulse rate has increased, and the pulse rate display section blinks. (N22 → n30 → n31). Also,
If the state of exceeding the upper limit pulse rate continues for 30 seconds or more, an error notification sound is output, an error display indicating that is displayed, and the physical strength measurement is terminated as it is. (N23 → n32
→ n33).

After 60 seconds have elapsed since the start of the measurement,
It is determined whether or not the average rotation speed Ravg of the pedal until then does not exceed 5 rpm. (N34). Ravg
Is less than or equal to 5 rpm, the resting pulse rate measurement is terminated normally, but if Ravg exceeds 5 rpm, an error notification sound is output and an error display to that effect is performed (n34 → n35 → n36). ). This prevents subsequent erroneous measurements due to the use of HR0 obtained during the non-resting state as the resting pulse rate.

FIG. 7 is a flowchart showing a processing procedure of pulse rate measurement in a state where a load is applied to the exerciser in each of the first, second and third stages. First, the rotational speed and pulse rate of the pedal are measured, and the elapsed time is counted. (N41). Subsequently, it is determined whether or not the measured pulse rate exceeds a predetermined upper limit pulse rate (n42). If the pulse rate does not exceed the predetermined upper limit pulse rate, an average rotation speed Ravg of the pedal is calculated. And the elapsed time is 2
It is determined whether it is longer than 30 minutes and not longer than 2 minutes 45 seconds (n43 → n44 → n45 → n46). When the elapsed time exceeds 2 minutes 30 seconds and is not longer than 2 minutes 45 seconds, it is determined whether the pulse rate is a predetermined abnormal pulse rate (n4).
7). If the pulse rate is not abnormal, the average value of the pulse rate for 15 seconds from the elapsed time of 2 minutes 30 seconds to 2 minutes 45 seconds is calculated as the pulse rate at that load (n48). In the first stage, this pulse rate is HR1, and in the second stage, this pulse rate is HR1.
In the second and third stages, this pulse rate becomes HR3. By using the pulse rate after a lapse of 2 minutes and 30 seconds after the load change as described above, the exerciser waits for the pulse rate to become stable under the new load. Also, the first
Each of the second and third stages is 3 minutes, and after 2 minutes and 45 seconds, the pulse of the next stage is given due to the feeling of tension or expectation that the load of the next stage will be given or that the physical strength measurement is completed. Since the number tends to increase, that period is also not used to measure the pulse rate. If the pulse rate exceeds the predetermined upper limit pulse rate for some reason, a notification sound is output to notify the user of the fact, and the pulse rate display section blinks (n42 → n50 → n51). If the state of exceeding the upper limit pulse rate continues for 30 seconds or more, an error notification sound is output, an error display indicating that is displayed, and the physical strength measurement is terminated as it is. (N43 → n52 → n53). If three minutes have elapsed since the start of measurement at each stage, the process at that stage is terminated (n49 → RET).

In the above-described embodiment, the first-stage load value W
Although 1 is a fixed value, this value W1 may be determined from the physical data of the exerciser and the pulse rate at rest. An example will be described with reference to FIG. For example, HRmax and a corresponding load value Wmax are obtained from statistical data from the age and gender of the exerciser. On the other hand, before setting W1, the resting pulse rate HR0 is measured. Therefore, a straight line connecting these two points is defined as a load value-pulse rate characteristic straight line, and W1 is obtained from this straight line and HR1 '. HR1 'is 3 between HR3' and HR0.
The equally divided increment is added to HR0 to obtain the same. As described above, HR3 'is obtained from the relationship between HRmax and HR0, or at a predetermined ratio to HRmax. In this way, if the physical data such as the age and gender of the exerciser and W1 from the resting pulse rate HR0 are obtained, the increase in the pulse rate from the resting pulse rate when the lightest load is first applied is calculated. It can be obtained moderately regardless of individual differences of athletes.

In the above example, the age and gender of the exerciser are used as the body data, but generally the HRmax, W
The parameter of the statistical data for obtaining max may be body data. For example, when using a relational expression or a table for obtaining Wmax using weight as a parameter in addition to age and gender, weight is also one of the body data.

In the above-described embodiment, an example has been shown in which the load value-pulse rate characteristic is obtained by setting the load value in the first, second, and third stages, and the maximum oxygen intake is calculated. This step may be two steps. In the case of two stages, the load value W1 is set in the first stage and the steady pulse rate HR1 is measured. In the second stage, the load value for the target pulse rate is set, and the actual steady pulse rate at that time is measured. A regression line may be obtained from the first and second load values and the steady pulse rate. Note that a regression line may be obtained at three points including the resting load value (= 0) and the resting pulse rate HR0. However, in general, the linearity of the load value-pulse rate characteristic in a low load region near resting. Should be taken into account.

The number of steps for changing the load value may be four or more. In general, a load value that divides the load value at a certain stage and the target exercise load value equally by the remaining number of stages is set as What is necessary is just to set the load value of the next stage so that it may become.

FIG. 9 shows an example of four stages. First, FIG.
(A), the load between the HR1 and the HR4 'is divided into three equal parts, and the load value corresponding to the pulse rate HR2' increased from HR1 by one third of the pulse rate is calculated in the second stage. Load value W
Set as 2. This means that the load value (W4) corresponding to HR4 'is determined from the load value-pulse rate characteristic straight line, and
By dividing the interval between 1 and (W4) into three equal parts, an increase in the load value is obtained,
This is the same as obtaining a value obtained by adding the increment to W1 as W2. Next, as shown in (B), the actual pulse rate HR2 at the load value W2 is measured, and a regression line is obtained from three points at rest and in the first and second stages, and the relationship between HR2 and HR4 'is obtained. A load value corresponding to the pulse rate HR3 'obtained by dividing the interval into two equal parts is set as the load value W3 of the third stage. This means that HR
This is the same as obtaining the load value (W4) corresponding to 4 'from the load value-pulse rate characteristic straight line, and obtaining the load value obtained by equally dividing W2 and (W4) into W3. Next, as shown in (C), a load value corresponding to the target pulse rate HR4 'is set as the load value W4 of the fourth stage, and the actual pulse rate HR4
Is measured. Then, a regression line is obtained from the four points in the first to fourth stages, and the load value Wm corresponding to the maximum pulse rate HRmax is obtained.
Find ax.

In the above-described embodiment, the resting pulse rate is measured and used to set the load value in the second stage. However, if the stable pulse rate is unknown, A load value-pulse rate characteristic line may be obtained from two load values having different values and the pulse rate at that time, and the load value at each subsequent stage may be set. An example is shown in FIG. First, a load value-pulse rate characteristic straight line is obtained from the two points W1, W2, HR1, and HR2 in the first and second stages, and a load value W3 for an intermediate value HR3 'between HR2 and HR4' is set. Is set as the load value of the third step, the actual pulse rate HR3 is measured, a load value-pulse rate characteristic straight line is obtained at the first, second, and third points, and four steps are obtained from the straight line and HR4 '. Eye load value W4
Should be obtained.

In the configuration of the training apparatus shown in FIG. 3, the program is written in the ROM inside the CPU 111 in advance. However, the program to be executed by the CPU may be provided from an external device via a recording medium. For example, as shown in FIG. 11, by writing a program in advance on an IC card 118 and attaching it to an IC card interface (reader) 117,
The CPU 111 sequentially reads out the programs in the IC card 118 and executes the above-described predetermined processing. Alternatively, such a program recording medium does not need to be a semiconductor memory, and may be a floppy disk or another recording medium.
The program may be loaded into the internal RAM of the CPU 111 or written into a writable ROM, so that the program may be executed once loaded therein.

[0039]

According to the first, seventh and ninth aspects of the present invention, the exercise load-pulse rate characteristic of the exerciser is estimated on the basis of the pulse rate in a plurality of stages of different exercise loads, and then the other characteristics are estimated. Because the exercise load value at any stage is set,
Unlike the conventional case where the load in the next stage is determined based on the absolute value of the pulse rate in each load stage, an accurate load more suitable for the physical strength of the exerciser can be given.

According to the second, eighth, and tenth aspects of the present invention, the load value-pulse rate characteristic can be obtained more accurately without biasing the distribution of points on a straight line or a curve representing the load value-pulse rate characteristic. be able to. In addition, even if the physical strengths of the exercisers are different, since the load is always applied only to the load corresponding to the target pulse rate, the physical strength can be measured under the same exercise intensity for each exerciser regardless of the exerciser.

According to the third aspect of the present invention, the change in the pulse rate can be recognized at the time when the load is first applied, and the load value in the subsequent stages can be set accurately.

According to the fourth aspect of the present invention, the difference between the pulse rate at the time of applying a load and the pulse rate at rest can be obtained appropriately.

According to the fifth aspect of the present invention, the pulse rate in a state where the pulse is stabilized after the exercise load is changed and before the next exercise load is changed can be reliably obtained.

According to the sixth aspect of the present invention, the physical strength can be easily measured using the motorcycle training apparatus.
