Description

Description: TECHNICAL FIELD The present invention relates to a physical fitness diagnostic device for diagnosing physical fitness equivalent to endurance and potential by load exercise.

(Prior art) Conventionally, physical strength measurement that incorporates multiple items such as back muscle strength and grip strength measurement with a muscle strength measuring instrument and running time measurement such as 50 m running with stopwatch has been generally performed at schools. It is being appreciated.

(Problems to be Solved by the Invention) However, such a conventional physical strength measurement is mainly for accumulating measurement data, and attempts to examine the physical strength characteristics of the subject in more detail based on these measurement data. Since it was not a thing, it was difficult to give life guidance to maintain or improve its physical strength in the future.

In addition, it takes a lot of physical strength to measure physical fitness, which is too heavy for adapting to middle-aged and elderly people.

(Means for Solving Problems) The present invention has been made for the purpose of solving the problems as described above. To achieve this object, the present invention provides a plurality of different exercise load increasing rates. The input unit for inputting the time required for the subject's pulse to reach a preset pulse for each exercise, and the work load of each exercise is calculated from the exercise load increase rate and the required time, and all exercises are performed. Is calculated as the endurance, and that value is included in the slope, and time t = in a straight line passing through the measurement result point (time, work amount) of the exercise having the largest exercise load increase rate among the above exercises. The calculation processing unit calculates the value of the work amount p of 0 as the potential, and the output unit that outputs both or one of the endurance and the potential.

(Working) With the above configuration, the endurance is calculated by averaging each exercise based on the values of the required time and the amount of work obtained by performing multiple exercises with different exercise load increase rates. The potential was calculated by weighting the exercise with the largest increase rate.

(Examples) Examples of the present invention will be described in detail below with reference to the drawings.

First, the structure of the embodiment shown in FIGS. 1 to 6 will be described.

As shown in FIG. 1, an apparatus for diagnosing physical fitness of the present embodiment has an ergometer 10 which also serves as a measuring device and an input device, a microcomputer 20 as an arithmetic processing device, a screen display device 30 and a printer 40 as output devices. And are equipped with.

The ergometer 10 is a bicycle-type load trainer that is a gradually increasing load type in which a constant load gradually increases with time regardless of the rotation speed of the pedal, and the initial work rate and the gradually increasing rate are set arbitrarily. It is possible.

Here, as shown in the graph in Figure 2,
W ₀ without changing the so subject performed a light load exercise and weight bearing exercise by varying the increasing rate, the load time was required until the pulse of the subject reaches the set number pulse for movement t _1, Measure t ₂ .

In addition, the set pulse rate is 60% VO ₂ max of the subject from Table 1, for example.
Determine (60% of bottom oxygen uptake) and set.

Further, a recording device is connected to the ergometer 10, and if an IC card is set in the recording device during measurement, the required time for each load exercise, that is, the light load required time t ₁ and the heavy load required time The mechanism is that t ₂ is converted into an electric signal and data is automatically input to the IC card.

The microcomputer 20 performs arithmetic processing based on input data input to the IC card and outputs the arithmetic processing result.

Regarding the contents of the arithmetic processing, first, the light load required time t ₁ and the heavy load required time t ₂ are respectively applied to the following equations to calculate the light load work amount P ₁ and the heavy load work amount P ₂ .

W ₀ ; Work rate at the start of light / heavy load exercise W ₁ ; Work rate at the end of light load exercise W ₂ ; Work rate at the end of heavy load exercise Next, these light load work P ₁ and heavy load work and P _2, calculates the endurance a by applying a light load required time t ₁ and a heavy load duration t ₂ in the following equation.

Further, as shown in FIG. 3, the coordinate is plotted with time on the horizontal axis and work on the vertical axis, and the slope is endurance a and the coordinate point (t ₂ , P
Draw a straight line through ₂ ), read the intersection with the vertical axis, that is, the intercept, and calculate the value as the potential b.

The potential b indicates the so-called reserve power that the subject has not yet demonstrated and has hidden, and this potential b is a straight line passing through the coordinate points (t ₂ , P ₂ ) obtained by heavy load exercise. Since it was calculated from, it was evaluated by taking into consideration not only endurance but also muscle strength such as leg strength.

The potential b may be calculated by applying it to the equation b = P ₂ −at ₂ instead of calculating it by graphing it as described above.

The screen display device 30 displays the calculation result of the microcomputer 20 in the form of a graph while comparing it with the standard value as shown in FIG. 4, and the printer 40 prints it out. .

As described above, in the physical fitness diagnostic apparatus of the present embodiment, since the endurance that represents aeropower and the potential that represents reserve power are output, it is easy for the subject to understand for maintaining physical strength or improving physical strength. Information can be provided.

For example, it is understood that the person (a) who obtained the result as shown by the solid line in FIG. 4 is a person who has poor endurance and potential. , As a first step, it turns out that it is better to teach so that it is parallel to the standard line shown by the dotted line.

Also, the person (b) who obtained the result as shown by the alternate long and short dash line in FIG. 4 is a person who has excellent potential but inferior endurance. It can be seen that there is plenty of room for improvement by incorporating exercises that enhance power.

Moreover, since the light load required time and the heavy load required time to reach the set pulse are used as input data, the measurement time can be shortened and the set pulse can be reasonably set according to each subject. Since it can be set, the effect is that it can be widely adapted to middle-aged and elderly people with peace of mind.

Here, in order to clarify the reliability of this physical fitness diagnostic apparatus, the following two experimental results will be described.

In each experiment, as shown in Fig. 5, the work rate at the start of exercise was set to 50 W / min, from which there was a light load exercise in which the load gradually increased at a rate of 12.5 W / min, and a rate of 25 W / min. This is the result obtained by performing heavy load exercise in which the load gradually increases.

(Experiment 1) Five test subjects as shown in Table 2 were subjected to light load exercise and heavy load exercise until they could withstand the load exercise, and the time required for each load exercise and VO ₂ max (maximum oxygen uptake). Amount) and was measured. Table 3 shows the measurement results.

Next, for each subject, the work load and endurance were calculated from the light load exercise time and the heavy load exercise time until reaching 80% VO ₂ max, and the endurance as the calculation result and the VO as the measurement result were calculated. _In contrast to ₂ max, as shown in FIG. 6, the correlation between VO ₂ max, which is a measure of endurance, and endurance was significant in the 5% rate test.

(Experiment 2) An upper limit pulse rate was set to 60% VO ₂ max, and an experiment in which light load exercise and heavy load exercise were performed until the set pulse rate was reached was performed once for subject A before jogging into the daily routine. Then, after putting it in, it was performed twice, a total of three times. Table 4 shows the measurement results and calculation results.

From this result, it was found that the subject A came to be able to put his / her jogging into the daily routine so that the potential could be exerted and the endurance was improved.

Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and even if there are design changes and the like within the scope not departing from the gist of the present invention, it is included in the present invention. Be done.

For example, in the embodiment, the endurance and the potential were calculated based on the measurement results of the light load exercise and the heavy load exercise performed by changing the load in two stages, but the load was further changed in three stages or four stages. The load exercise may be performed, and the endurance and the potential may be calculated based on the result.

Further, a floppy disk may be used instead of the IC card, and a person may input data to these with a keyboard.

Further, in the embodiment, the screen display device and the printer are arranged to display the arithmetic processing result of the microcomputer in a graph, but they may be displayed in a table. As the output device, only one of the screen display device and the printer may be used, or another output device may be used.

(Effects of the Invention) As described above, in the physical fitness diagnostic apparatus of the present invention, the accuracy of endurance measurement can be improved, and at the same time, the potential of the subject is also output, so that the physical strength of the subject can be maintained or improved. Can provide useful information for prescribing exercise.

Moreover, since the light load required time and the heavy light load required time until reaching the set pulse are used as the input data, the measurement time can be shortened and the set pulse can be set according to each subject. Therefore, it is possible to obtain the effect that it can be widely adapted to middle-aged and elderly people with peace of mind.
