Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a device for measuring the motor function (motor ability) of a living body.

PRIOR ART In general, the range of fluctuations in the operating state of the circulatory system that occurs in response to exercise is larger in people with high circulatory function than in people with poor circulatory function. In addition, the changes over time show various types depending on the superiority or inferiority of the circulatory function. For this reason, for example, the pulse rate is measured before and after a certain exercise, immediately after a certain exercise, and after a certain period of time has elapsed, and motor function is determined based on the comparison of these pulse rate changes with standard values. Ta.

Problems to be Solved by the Invention However, according to the conventional method of understanding motor function, the pulse rate is measured before and after exercise, immediately after exercise, and after a certain period of time has elapsed.
It is troublesome to use a table to select values indicating motor function corresponding to changes in pulse rate, and it is particularly difficult for inexperienced users to understand motor function by themselves.

Means for Solving the Problems The present invention has been made against the background of the above circumstances, and its gist is (1) an exertion intensity detection means for detecting the exertion intensity of a living body due to exercise;
(2) a target exertion intensity setting means for presetting a certain target exertion intensity; and (3) a means for setting an actual total amount of work performed by the living body until the exertion intensity of the living body reaches the target exertion intensity. and (4) a display means for displaying a value representing the motor function of the living body based on the total amount of work detected by the total amount of work detection means. be.

Effects and Effects of the Invention In this way, the actual total amount of work performed by the living body until the exertion intensity of the living body reaches the target exertion intensity is detected by the total work amount detection means, and A value representing the motor function of the living body is displayed on the display means based on the amount of work. Therefore, the motor function of the living body can be measured very easily and quantitatively.

Here, the exertion intensity is the magnitude of the load on an individual living organism (internal exercise load), and is the amount that appears on the living organism in response to its exercise, for example,
The heart rate (pulse rate) of the living body, blood pressure value, PRP (product of heart rate and blood pressure value), etc. may be used. Further, the target exertion intensity may be a constant value, but is preferably a value obtained by increasing the value by a predetermined ratio based on the value when the living body is at rest or not exercising. The ratio is appropriately selected depending on the age, sex, weight, athletic ability level, etc. of the living body.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail based on the drawings.

In FIG. 1, numeral 10 is an ergometer that applies an exercise load to the subject by making him or her exercise, and is equipped with a loader for applying rotational resistance. Although a generator, an eddy current type electromagnetic brake, etc. can be used as the load device, a generator is used in this embodiment. As the ergometer 10 rotates, power from the generator is consumed by resistors and the like, and the microcomputer 12
The power consumption is adjusted by the ergometer 10, and the load (rotational resistance) of the ergometer 10 is controlled. The ergometer 10 is provided with a wattmeter 13 for detecting the total amount of work of the person to be measured, and the amount of power generated by the generator (power consumption of the resistor) is then transmitted to the microcomputer 12. ing.

The pulse sensor 14 constitutes the exertion intensity detection means of this embodiment and detects the pulse of the subject. We are prepared. The optical sensor detects a change in blood volume in the earlobe, that is, the pulse, and a pulse signal SM representing the pulse is supplied to the I/O port 16 of the microcomputer 12.

Name, age, sex, weight, pulse rate, motor function level, previously measured motor function data, measurement date and time, etc. are stored in the memory card 18 that each person to be measured owns. The card reader 20 reads the information stored in the memory card 18. When the memory card 18 is inserted into the card reader 20, a signal indicating the start of motor function measurement is output and the information in the memory card 18 is read. The data is transmitted to the microcomputer 12. The clock circuit 22 also transmits time data representing the current date and time to the microcomputer 12.

The microcomputer 12 has a CPU 24 and a ROM 2 connected to each other by a data bus line.
6. Equipped with 28 RAM. The CPU 24 is
ROM2 while using the primary storage function of RAM28
The input signal is processed according to a program stored in advance in the ergometer 6 to control the load on the ergometer 10, and the display 3 is a display means of this embodiment.
0, the time course curve 32 of the value representing the detected exertion intensity and the amount of work are displayed, and at the same time, when the exertion intensity reaches the target exertion intensity, a value representing the motor function, such as the total amount of exertion up to that point or the amount thereof, is displayed. Display the value calculated separately based on the above.

As shown in FIG. 2, the display 30 is equipped with an image display device such as a cathode ray tube or LCD that can display images using a large number of pixels, and the display screen 38 is placed at a position where it can be easily seen by the person being measured. will be established. On the display screen 38, in Cartesian coordinates including a time axis 40 and an axis 42 for indicating a value representing the exertion intensity (pulse rate in this embodiment), the time course curve 32 and a line 34 indicating the target exertion intensity are displayed. In addition, in a display place 50 provided below the orthogonal coordinates, values indicating past motor functions and values measured this time are displayed in analog form in parallel with the axis 44 for indicating motor functions. ,
And the digital value is displayed at the display location 52 on the right side thereof. In addition, the display 30
It may be a plotter or a dot printer, or it may be a simple one that displays only values indicating motor function.

The operation of this embodiment will be explained below with reference to the flowchart of FIG.

First, in step S1, the memory card 18
It is determined whether or not the card is attached to the card reader 20, and if it is not attached, the execution of step S1 is repeated. When the memory card 18 is inserted, step S2 is executed and the memory card 1 is inserted.
As the information stored in 8 is read,
Step S3 is executed and the target exertion intensity (target pulse rate in this embodiment) is determined from the plurality of values stored in advance in the ROM 26, including the age, gender, weight, and pulse rate of the subject stored in the memory card 18. , is selected and automatically set according to the motor function level. This target exertion intensity is determined by increasing the resting pulse rate by a percentage (for example, 50% to
100%). Furthermore, step S4 is executed, and a line 34 representing the selected target exertion intensity is displayed parallel to the time axis 40, and a value representing the motor function previously measured and stored in the memory card 18 is displayed. A graph is displayed in a display location 50 on the screen 38 in parallel with the axis 44 . Bar 46 in FIG. 2 displays the previously measured value.

Then, by executing the subsequent step S5, a message to the subject, for example, "Please rotate the ergometer until the end instruction is given" is displayed in the voice or on the display screen 38. In the following step S6, it is determined whether or not the subject has started rotating the ergometer 10 in accordance with this rotation instruction. If the ergometer 10 has not started rotating, step S6 is repeatedly executed. When it is determined that the rotation has started, steps S7 and subsequent steps are executed. That is, by executing step S7, the timer is reset and time measurement is started, and by executing the following step S8, the load of the ergometer 10, that is, the rotational resistance, is adjusted to the preset load curve. controlled to follow.

In the load control process of the ergometer 10 after step S8 is executed, execution of the interrupt routine shown in FIG. 4 is permitted each time the pulse signal SM is supplied to the I/O port 16. In this interrupt routine, the pulse cycle is detected by executing step SW1. And the next steps
By executing SW2, the pulse rate (instantaneous value) is determined based on the period of the pulse, and the determined pulse rate is stored in the RAM 28 together with time data representing the elapsed time or current time, and the determined pulse rate is Display screen 3 with number display 30
8. Therefore, by repeatedly executing this interrupt routine, the pulse rate is determined one after another, and the display screen 38 shows the response of the subject due to the external exercise load and the internal exercise load. A time-lapse curve 32 representing (exertion intensity) is displayed while expanding. FIG. 2 shows the display state when the actual pulse rate reaches the target pulse rate (target exertion intensity).

In the step S9, the pulse rate determined by executing the interrupt routine is read, and in the following step S10, it is determined whether a predetermined time set in the timer has expired.
If it has not expired yet, proceed to the next step S11.
is executed, but if it expires, the below-mentioned step S12 is executed. If the external load placed on the subject is too light, the actual pulse rate will not reach the target pulse rate and motor function will not be measured. The time is set on a timer.

In step S11, it is determined whether the actual pulse rate has reached the target pulse rate. If the point has not yet been reached, steps S8 and subsequent steps are repeated; however, if it is determined that the point has been reached, step S12 is executed.
is executed, and a message such as "Please stop the rotation of the ergometer" is displayed audibly or on the display screen 38. Therefore, the subject stops the rotation of the ergometer 10 in accordance with the stop instruction. Then, step S13 is executed and the load control of the ergometer 10 is ended.

Next, step S14 is executed to determine a quantity representing the motor function. The quantity representing this motor function is based on the total amount of exertion of the person to be measured, that is, the total generated power (watts/time) of the generator in the ergometer 10 detected by the wattmeter 13, or such a value. It is determined by finding simple numerical values or values classified into levels. And step S
15 is executed, numerical values indicating the motor function are displayed in a graph as shown by the bar 48 at a display location 50 on the display screen 38, and are numerically displayed at a display location 52. Note that the step S1
If it is determined at 0 that the timer has expired, that fact is displayed in step S15, and the numerical value representing the motor function is not displayed.

As described above, according to this embodiment, the ergometer is the amount of work performed by the person to be measured until the pulse rate, which is a reaction caused in the person to exercise and represents the exercise intensity, reaches the target exertion intensity. The power generated by the generators in the generator 10 is determined, and based on this, a value representing the motor function is displayed on the display 30. Therefore, the motor function of the subject is automatically and quantitatively measured.

Further, according to this embodiment, since the value indicating the new motor function is displayed in a graph in parallel with the previous measured value at the display location 50, by comparing the two, changes in the motor function can be easily understood. There are advantages. Further, according to this embodiment, since the time course curve 32 gradually expands during the exercise process of the subject, this provides encouragement to the subject and has the advantage of alleviating pain caused by monotony. However, the display at the display location 50 and the time course curve 3
Display 2 is not necessarily necessary for measuring motor function.

Although one embodiment of the present invention has been described above, the present invention can also be applied to other aspects.

For example, in the above-mentioned embodiment, pulse rate was used as a quantity representing the exertion intensity of the subject.
Instead, heart rate, blood pressure value, PRP (product of heart rate and blood pressure value), etc. may be used. This is because all of them correspond to myocardial oxygen consumption, are reactions that occur in a living body due to exercise, and reflect the internal exercise load of that living body. In such a case, the axis 42 becomes an axis indicating any of the heart rate, blood pressure value, PRP, etc., and the pulse sensor 1
Instead of 4, a heart rate sensor, blood pressure measuring device, or
It is necessary to provide a means for calculating PRP.

Further, the total workload of the person to be measured may be the total number of rotations of the ergometer 10 as long as the rotational resistance of the ergometer 10 is controlled to be constant. For example, if a treadmill is used, the distance traveled by the belt may be used.

Furthermore, since the total amount of work of the subject corresponds to the amount of oxygen consumed in the body, the total amount of oxygen consumed until the pulse rate reaches the target value is detected using a known oxygen consumption measuring device, This total oxygen consumption Y〓O ₂ (ml)
Alternatively, the amount representing the motor function of the subject may be determined based on the total oxygen consumption per unit body weight (ml/Kg) determined based on this.

Further, in the above-described embodiment, data such as the age of the subject was inputted using the card reader 20, but data of the subject or target pulse rate may be input using other input means such as a keyboard. You may also do so. In this case, the keyboard serves as the means for setting the target exertion intensity.

The above-mentioned embodiment is merely one embodiment of the present invention, and various modifications may be made to the present invention without departing from the spirit thereof.
