Description

  The present invention relates to an exercise amount estimation method and apparatus for estimating a state related to an exercise amount such as glycogen consumption in the body using a heartbeat.

  Glycogen is stored in the liver and muscles and is used as energy during exercise. In various sports, it is known that exercise capacity is significantly reduced when glycogen is depleted (see Non-Patent Document 1). For this reason, it is important for the maintenance of exercise capacity to measure the state related to the amount of exercise such as exercise capacity by measuring the amount of glycogen consumption in the body.

FIG. 1 is a configuration diagram showing a configuration of a momentum estimation device according to an embodiment of the present invention. FIG. 2 is a characteristic diagram showing the relationship between the RQ obtained by experiment and the heart rate. FIG. 3 is a flow chart for explaining a momentum estimation method according to the embodiment of the present invention. FIG. 4 is a flowchart for explaining another method of estimating momentum according to the embodiment of the present invention. FIG. 5 is a block diagram showing the hardware configuration of the momentum estimating device according to the present invention.

  Hereinafter, a momentum estimating device according to an embodiment of the present invention will be described with reference to FIG. This apparatus includes a measurement unit 101, a first calculation unit 102, a second calculation unit 103, a third calculation unit 104, an estimation unit 105, a storage unit 106, and a display unit 107.

  The measurement unit 101 measures the number of heartbeats (pulses) of the subject. The first calculator 102 calculates the exercise intensity of the subject at the time of measuring the heart rate from the heart rate measured by the measuring unit 101. For example, the measured heart rate is temporarily stored in the storage unit 106, and the first calculation unit 102 measures exercise intensity using the heart rate stored in the storage unit 106. For example, the first calculation unit 102 calculates exercise intensity according to (measured heart rate-resting heart rate of subject) / (maximum heart rate of subject-resting heart rate) (see Non-Patent Document 2) ). The maximum heart rate of the subject may be 220 minus the age of the subject. In addition, the resting heart rate of the subject may be 60. Also, the maximum heart rate of the subject and the resting heart rate of the subject may be measured in advance. These constants may be stored in the storage unit 106.

  The second calculator 103 calculates the consumed calories of the subject at the time of measuring the heart rate from the exercise intensity calculated by the first calculator 102. For example, the second calculation unit 103 calculates consumed calories by “maximum oxygen intake of subject / 3.5 × exercise intensity × 1.05 × weight of subject (kg) × measurement time (h) (non- In this case, the total calorie consumption (kcal) consumed within the measurement time is calculated, and the maximum oxygen uptake of the subject / 3.5 × exercise intensity × 1.05 × subject The calorie consumption may be calculated by “body weight (kg) × 1/3600 (s)”. In this case, the calorie consumption (kcal / s) per unit time (s) is determined. The weight of the subject and each constant may be stored in the storage unit 106.

  The third calculator 104 calculates, from the heart rate measured by the measurement unit 101, the rate of anoxic exercise and the rate of an aerobic exercise of the subject at the time of measuring the heart rate. The third calculation unit 104 calculates, for example, the rate of anoxia exercise based on the contribution rate of the anoxia exercise for each heart rate calculated in advance in the subject, and is obtained in advance in the subject Calculate the proportion of aerobic exercise based on the contribution rate of aerobic exercise for each heart rate.

  Hereinafter, aerobic exercise and anaerobic exercise will be described. Calorie consumption is divided into calories consumed by aerobic exercise and calories consumed by anaerobic exercise. The proportion of anoxic exercise in consumed calories can be determined by measuring the contribution rates of aerobic exercise and anoxic exercise in advance for each heart rate.

  When respiratory quotient (RQ) is 1, oxygen consumption by anaerobic exercise is 100%, and when RQ is 0.7 (≒ 102/145), oxygen consumption by aerobic exercise is 100%. Become. For this reason, if RQ is calculated, the oxygen consumption ratio of anoxic exercise and aerobic exercise can be known. For example, the rate of anoxic exercise can be determined by “rate of anoxic exercise = (RQ−0.7) / (1−0.7)”. The respiratory quotient (RQ) is a volume ratio of carbon dioxide output to oxygen consumption until nutrients are decomposed in the living body at a certain time and converted to energy.

  An example of the relationship between RQ obtained by experiment and heart rate is shown in FIG. From this graph, the heart rate and the rate of anoxic exercise (oxygen consumption conversion) can be found. The heart rate is the ratio of the heart rate at that time to the maximum heart rate.

  The estimation unit 105 estimates the muscle glycogen consumption of the subject from the consumed calories calculated by the second calculation unit 103, the rate of anoxic exercise calculated by the third calculation unit 104, and the rate of aerobic exercise. .

  For example, the estimation unit 105 first calculates “the consumed calorie calculated by the second calculation unit 103 × (5.046 × the ratio of anoxia exercise calculated by the third calculation unit 104) / (4.686 × third calculation unit Based on the ratio of aerobic exercise calculated in 104 + 5.046 × the ratio of anoxic exercise calculated in the third calculation unit 104 ”, consumed calories of glycogen in the subject at the time of heart rate measurement are calculated. The calories consumed by the anoxic exercise become the consumed calories of glycogen.

  Further, the estimation unit 105 calculates the consumption amount of glycogen in the subject at the time of heart rate measurement, based on “calculated calorie consumption of glycogen / 4”. The calories that can be generated per gram of glycogen is 4 kcal.

  Further, the estimation unit 105 estimates the muscle glycogen consumption of the subject based on “(the amount of glycogen stored in the body of the subject−consumed amount of glycogen calculated) / consumed amount of glycogen calculated”. The amount of glycogen that can be stored in the human body is said to be about 300 to 500 g for muscle and about 100 g for liver (see Non-Patent Document 4). Each constant may be stored in the storage unit 106. Further, the calculated consumption amount of muscle glycogen is displayed on the display unit 107.

In the second step S102, exercise intensity is calculated according to (measured heart rate-subject's resting heart rate) / (subject's maximum heart rate-resting heart rate).

  Next, in a third step S103, the second calculator 103 calculates the calorie consumption of the subject at the time of heart rate measurement from the calculated exercise intensity. In the third step S103, “maximum oxygen intake of subject / 3.5 × exercise intensity × 1.05 × weight of subject (kg) × measurement time (h), or maximum oxygen uptake of subject / 3” .5 × exercise intensity × 1.05 × weight of the subject (kg) × 1/3600 (s) "to calculate the calorie consumption.

  Next, in a fourth step S104, the third calculating unit 104 calculates the rate of anoxic exercise and the rate of aerobic exercise of the subject at the time of measuring the heart rate from the measured heart rate. In the fourth step S104, the rate of anoxic exercise is calculated based on the contribution rate of anoxic exercise for each heart rate determined in advance in the subject, and the heart rate determined in advance in the subject Calculate the proportion of aerobic exercise based on the contribution rate of calories consumed by aerobic exercise.

  Next, in a fifth step S105, the estimation unit 105 estimates the muscle glycogen consumption of the subject from the calculated consumed calories, the calculated ratio of anoxic exercise, and the ratio of aerobic exercise.

  In the fifth step S105, first, "the consumed calories calculated in the third step x (5.046 x the ratio of the anoxic exercise calculated in the fourth step) / (4.686 x the aerobic exercise calculated in the fourth step) The calorie consumption of glycogen in the subject is calculated by “ratio of 5.046 × ratio of anoxic activity calculated in the fourth step)”. Subsequently, the consumption amount of glycogen is calculated by “calculated calorie consumption of glycogen / 4”. Subsequently, the muscle glycogen consumption of the subject is estimated by “(the amount of glycogen stored in the body of the subject−consumed amount of glycogen) / consumed amount of glycogen calculated”.

  The estimation unit 105 may estimate the exercise allowance of the subject by dividing the estimated consumption of muscle glycogen by the amount of muscle glycogen stored in the body of the subject.

Next, in a fourth step S104, the third calculating unit 104 calculates the rate of anoxic exercise and the rate of aerobic exercise of the subject at the time of measuring the heart rate from the measured heart rate.

  Next, in a fifth step S105, the estimation unit 105 estimates the muscle glycogen consumption of the subject from the calculated consumed calories, the calculated ratio of anoxic exercise, and the ratio of aerobic exercise.

  Each step mentioned above is the same as that of the momentum estimation method explained using FIG. In addition to this, in the sixth step S106, the estimation unit 105 divides the estimated muscle glycogen consumption by the amount of muscle glycogen stored in the subject's body to estimate the subject's exercise allowance.
