Problems solved by technology

[0009] ① The data obtained by using the device and method for determining the degree of exercise can only be used in purely physiological training and determining the degree of exercise in sports, and cannot be effectively used
[0010] ②The setting of exercise intensity is not suitable for the exercise ability of various people, and the exercise effect as the purpose cannot be fully achieved
[0011] ③ As the exercise intensity suitable for the exercise ability of various people, AT is generally considered to be the most suitable, but a large device such as an inspiratory gas analyzer is required for measurement, and it cannot be mounted on a high-speed measurement and practical exercise equipment
[0012] ④ AT, which demonstrates aerobic exercise capacity as an important method of physical strength, cannot be judged and displayed on exercise equipment for the reason of ③ above.

Embodiment 1

[0054] figure 1 It is a block diagram showing the circuit configuration of a bicycle ergometer as an example of the exercise equipment according to the first embodiment of the present invention. The dynamometer includes: ECG sensor 1, which is used to detect ECG signals; preamplifier 2, which is used to amplify the output signal of sensor 1; filter 3, which is used to filter out noise; amplifier 4, which is used to To further amplify the electrocardiographic signal to an appropriate level; A / D converter 5; CPU6, which is used to perform various processing; keyboard input device 7; display 8; load device (rotational load) 9.

[0055] figure 2 It is an external oblique view of the bicycle ergometer of this embodiment. refer to figure 2 , The bicycle ergometer comprises: a saddle 11, a handle 12, an operating part 13, a pedal 14, a front frame 15, and a rear frame 16. Operating part 13 comprises: keyboard input device 7, display 8 (referring to figure 1 ). In this ergomet...

Embodiment 2

[0083] Embodiment 2 of the present invention will be described below. In Example 2, the anaerobic exercise threshold was estimated using the power of the heartbeat interval fluctuation. In Example 2, the bicycle ergometer used and the data obtained from the test subjects were the same as in Example 1.

[0084] Figure 18 It is a flowchart showing the processing contents of the electrocardiographic signal processing in the second embodiment. refer to Figure 18 , in this embodiment, the detection of the electrocardiogram signal at rest is first performed (ST51). Next, the calibration operation is performed, the start of measurement is displayed, and the control of the load is started (ST52 to ST54). The operations up to this point are the same as in the first embodiment.

[0085] In Example 2, peak detection of the electrocardiographic signal from the electrocardiographic sensor 1 is performed, and RR interval data (one cycle of heartbeat) is calculated. Then, the power (...

Embodiment 3

[0091] Embodiment 3 of the present invention will be described below. The oxygen intake can be calculated from the load when the anaerobic exercise threshold value detected by the method of one of the above-mentioned embodiments 1 or 2 appears, and the exercise load can be controlled by it. In the calculation of this oxygen uptake, the oxygen uptake (VO2) is calculated from the load when AT appears by the conversion formula, and VO2 per 1 kg of body weight is calculated|required.

[0092] For example, when a person with a body weight of 70 kg exhibits AT at 100 W of bicycle ergometer exercise, the oxygen intake amount is calculated using the following equation (4).

[0093] VO2 (ml / kg / min) = load (W) ÷ 0.232 × 14.3 ÷ 5.0 ÷ body weight (kg)

[0094] ...(4)

[0095] Here, 0.232 indicates that the exercise efficiency of the bicycle ergometer is 23.2%, 14.3 is a conversion factor of 1 watt = 14.3 cal / min, and 5.0 is a conversion factor of ...

Abstract

In an exercise machine, when a measurement starts, an electrocardiographic signal is detected by an electrocardiographic sensor (1) (ST33), a load drive is started (ST4), and heartbeat rate intervals of the electrocardiographic signal are sequentially obtained. A fluctuation of heartbeat rate intervals PI(n)% is obtained from a calculation formula in which the RR interval RR(n+1) of the current heartbeat is subtracted from the RR interval RR(n) of the previous heartbeat, which is then divided by RR(n) and multiplied by 100% (ST5). Entropy is calculated from 128 pieces of such PI (ST6). From the change of the entropy under the gradually increasing load (ST8), a minimum point of the entropy is obtained, which point is designated as an anaerobic threshold point (ST7). The load of the exercise machine is controlled employing this anaerobic threshold.

Description

technical field [0001] The present invention relates to sports equipment such as a bicycle ergometer, a stationary treadmill, and a rowing ergometer, a physical strength evaluation method, and a pulsometer. Background technique [0002] Interesting in the present invention, the device and method for determining the degree of exercise are disclosed in, for example, International Publication No. WO96 / 20640. According to the same publication, it is disclosed that the heart rate of a person engaged in training is monitored, the heart rate is calculated by measuring, for example, a QRS complex waveform from the electrocardiogram signal, and the exercise degree of the person in training is determined from the power of the spectrum derived from the heart rate. [0003] Conventionally, other muscular endurance measuring devices and muscular endurance measuring methods for exercising humans are disclosed in, for example, Japanese Patent Publication No. 7-38885. If this bulletin is a...
