Pendulum 11 pivotally supported by 5 and biased by a torsion spring 14
And a reed switch 13 and a magnet 12 attached to the pendulum 11 for applying a magnetic field to the reed switch 13 are used.

計算している。In such a pedometer, the pendulum 11 swings due to the movement (for example, walking) of the person to be measured wearing the pedometer, and the reed switch 13 is turned on / off by the magnet 12 attached to the pendulum 11. By counting the number of times this on / off is performed by a counting means (not shown), the number of steps of the person to be measured is measured, the strength of exercise is estimated by the number of steps per unit time, and the calorie consumption is calculated from this strength of exercise. are doing.

いう問題がある。In the pedometer, however, there is a person to be measured irrespective of the magnitude of the pedometer shake (that is, the swing of the pendulum 11) associated with the person's motion (eg, walking, jogging, etc.). Since each swing of the pendulum 11 caused by the motion is counted as one step, the consumed calorie calculated based on the number of steps measured by the pedometer has a problem that the error is large.

In such a motion calorimeter, when the person to be measured exercises, the weight 23 causes the piezo ceramics 24 to move.
A force is applied to the piezoelectric ceramics 24, and the voltage generated in the piezoelectric ceramics 24 is detected via the lead wire 22. Therefore, not only the number of steps but also the intensity of exercise can be detected by detecting the change in acceleration accompanying the exercise of the person to be measured as the analog output of the voltage, and the calorie consumption is calculated from the number of steps and the intensity of exercise. can do. The number of steps during walking is obtained from the frequency of the output voltage from the acceleration sensor, and the moving distance is calculated from the product of the stride and the number of steps. Here, the stride may be made by inputting a measured value of the stride of the subject measured in advance, or calculated by an equation such as, for example, stride (cm) = height (cm) -100 (cm).

１００拍／分であるとされている。To obtain the calorie consumption from the acceleration, refer to FIG.
As shown in, the property that the calorie consumption is proportional to the output voltage from the acceleration sensor is used. However, the exercise calorimeter does not consider an exercise form (for example, going up a hill, going down a hill, etc.) which is an important factor related to the calorie consumption. Therefore, there has been proposed a calorie consumption meter capable of measuring the calorie consumption regardless of the exercise form of the person to be measured. This calorie consumption meter calculates calorie consumption from the heart rate of the person to be measured, and normally utilizes the property that human oxygen intake is proportional to the heart rate or pulse rate. Figure 2 shows the VO 2 / HR (oxygen uptake / heart rate) method (Hashimoto et al., Research on the state of decrease in physical activity of Japanese people and measures to improve it, Report of National Institute of Nutrition, 32, 53-6.
0, 1983) shows the relationship between heart rate and calories consumed. In this VO 2 / HR method, the proportional relationship between the calorie consumption and the heart rate in the inactive state is defined as the regression line A in view of the different proportional relationship between the calorie consumption and the heart rate when the physical activity is different. Assuming that the proportional relationship between the calorie consumption and the heart rate in the active state is the regression line B, the calorie consumption is calculated from the heart rate. Here, the regression line A is determined from the relationship between the heart rate and calorie consumption of sleep metabolism, basal metabolism, and rest metabolism, and the regression line B is gradually increased by a load-variable exercise device such as a bicycle ergometer. It is determined from the relationship between the heart rate and calories consumed. Also,
The heart rate at the intersection of the regression line A and the regression line B is approximately 90-
It is said to be 100 beats / minute.

る。The detection of the heart rate is performed by RR of an electrocardiogram waveform obtained from an electrode attached on the body surface like a normal electrocardiogram.
It may be calculated from the interval, or may be calculated from the pulse rate by detecting the pulse wave with an optical sensor attached to the ear, fingertip, or wrist. Therefore, in the case of calculating the calorie consumption from the heart rate, there is a great advantage that the measurement can be performed not only in walking or jogging but also in driving a bicycle or a boat.

確に判断できないという問題があった）。However, when the calorie consumption is calculated from the acceleration, the acceleration may increase even if the person to be measured is not exercising (for example, due to vibration in a vehicle such as a train). Since the acceleration increases, the measured calorie consumption may be larger than the actual calorie consumption (ie,
There was a problem that it was not possible to accurately determine whether or not the fluctuation in acceleration affects calorie consumption).

いという問題があった）。Further, the calorie consumption meter for calculating the calorie consumption from the heart rate has an advantage that the calorie consumption can be measured irrespective of the exercise form, but the calorie consumption at the resting heart rate is likely to be psychologically affected. Therefore, when the heart rate rises due to tension or anxiety, for example, even though the person is not exercising, the calorie consumption may be larger than the actual calorie consumption (that is, heart rate variability). There was a problem that it is not possible to determine whether or not it affects the consumption calorie).

The calorie consumption is calculated by one of the above formulas according to the judgment result of the degree judgment means. The physical activity level determination means compares the heart rate detected by the heart rate detector 2 with the reference heart rate (here, 95 beats / minute), and if the heart rate is equal to or higher than the reference heart rate, the heart rate is determined. It is determined that the number is “large”, the heart rate is “small” when the heart rate is less than the reference heart rate, and the acceleration detected by the acceleration detection unit 1 is compared with the reference acceleration. When the acceleration is equal to or higher than the reference acceleration, it is determined that the acceleration is “large”, and when the acceleration is less than the reference acceleration, the acceleration is determined to be “small”.

There is a physical activity level judging means for judging the magnitude of physical activity level based on the acceleration detected by the acceleration detecting section 1, and either the regression line A or the regression line B is decided according to the judgment result of the physical activity level judging means. This is different from the first embodiment in that this is selected and the calorie consumption is calculated from the heart rate.

ある。When the heart rate is less than 95 beats / minute, the calculating unit 3 of the calorie consumption meter determines that the person to be measured is inactive regardless of the judgment result of the physical activity judging means, and the regression line A Based on the heart rate, calculate the calorie consumption. On the other hand, when the heart rate is 95 beats / minute or more, when the determination result of the physical activity level determination means is “large”, it is determined that the person to be measured is in an active state, and the calorie consumption is calculated from the heart rate based on the regression line B. When the determination result of the physical activity level determination means is “small”, the calorie consumption is calculated from the heart rate based on the regression line A, assuming that the person to be measured is inactive. Therefore, in this calorie consumption meter, the calorie consumption is calculated from the heart rate based on the regression line A in a state where the heart rate is high even though the body is hardly moved, for example, in an excessively tense state or anxiety state. The error from the calorie consumption can be reduced.

もよい。In the calorie consumption meter according to the first embodiment, it is necessary to grasp two accurate calibration curves of the proportional relationship between the heart rate and the calorie consumption and the proportional relationship between the acceleration and the calorie consumption.
In this calorie consumption meter, an accurate calibration curve needs only one proportional relationship between the heart rate and the calorie consumption. In addition, the acceleration sensor in the calorie consumption meter of the first embodiment is preferably attached to the waist or the like in order to accurately measure the strength of exercise, but the acceleration sensor in the calorie consumption meter of the present embodiment can measure physical activity of a small or large level. It suffices if it can be discriminated and it is not necessary to wear it on the waist. Therefore, the consumption calorimeter should be shaped like the wristwatch shown in FIG. Is possible. Here, the display unit 4 displays the consumption calories and the like calculated by the calculation unit 3. In this case, the pulse rate may be obtained by detecting the pulse wave by providing an optical sensor or the like for detecting the pulse group of the person being measured in the calorie consumption meter, and the heart rate may be obtained from the pulse rate. .

カロリとの誤差を小さくすることができるのである。When the acceleration detected by the acceleration detection unit 1 is smaller than a predetermined value, the calculation unit 3 of the calorie consumption meter calculates the consumed calorie from the acceleration regardless of the determination result of the physical activity level determination means. On the other hand, when the acceleration detected by the acceleration detecting unit 1 is larger than a predetermined value, the calorie consumption is calculated from the acceleration when the judgment result of the physical activity level judgment means is “large”, and the judgment result of the physical activity level judgment means. When is “small”, the calorie consumption is calculated from the acceleration value in the preset inactive state, not the acceleration detected by the acceleration detection unit 1. Therefore, in the present calorimeter, the acceleration detection unit 1 detects the heart rate when the acceleration is large even though the heart rate is almost unchanged, for example, when the vehicle gets on a vehicle such as a train and the acceleration is increased due to the vibration of the vehicle. Since the calorie consumption is calculated using the acceleration value smaller than the acceleration, the error from the actual calorie consumption can be reduced.

際の消費カロリとの誤差が大きくなってしまう。In this calorie consumption meter, since it is sufficient that the heart rate can determine the magnitude of physical activity, it is not necessary to constantly measure the heart rate, and intermittent measurement may be performed. (Embodiment 4) By the way, in the calorie consumption meter according to Embodiment 2, when the physical activity level is judged from the acceleration by the physical activity level determination means, if the acceleration fluctuates significantly even with a temporary body movement, the physical activity level is calculated. It may be judged as “large”. For example, when the subject stands up from the sitting position or sits down from the standing position, the acceleration fluctuates greatly even though the calorie consumption is low due to temporary body movements. The degree is judged to be “large”, and the calorie consumption is calculated from the heart rate based on the regression line B. However, in the case of such body movement, since the physical activity is not such that energy metabolism (calorie consumption) is affected, the calorie consumption calculated from the heart rate based on the regression line B is the actual calorie consumption. The error between and becomes large.

リとの誤差を小さくすることができるのである。The calorie consumption meter according to the present embodiment is intended to reduce the error of the calorie consumption due to the above-mentioned cause, and its basic structure is substantially the same as that of the second embodiment. Therefore, only the characteristic points will be described. The physical activity level determination means of the calculation unit 3 of the calorie consumption meter determines the physical activity level to be one of two levels, large and small, based on the magnitude of the acceleration detected by the acceleration detection unit 1. Here, the calculation unit 3 has a time measuring means, and determines that the physical activity level is “high” only when the acceleration continuously exceeds the predetermined value for a predetermined time (for example, 10 seconds) or more. However, even if the acceleration is greater than the predetermined value and the duration is less than the predetermined time, it is determined that the physical activity level is “small”. In other words, with this calorie consumption meter, the physical activity level is judged to be "small" in the case of temporary physical movement such as standing up from the sitting position or sitting from the standing position, so an error from the actual calorie consumption is calculated. It can be made smaller.

This is not the case, as and cannot be compared directly. When the physical activity determined by the physical activity determination means is “small”, the calorie consumption is calculated from the proportional relationship between the heart rate and the calorie as shown by the regression line A, and when the physical activity is “large” Calculates the calorie consumption from the proportional relationship between the heart rate and the calorie consumption as shown by the regression line B.

Since it is not necessary to wear it on the waist, it becomes possible to wear the consumption calorimeter main body on the arm of the person to be measured with the band 1 having a shape like the wristwatch shown in FIG. . Here, the heart rate is measured by the heart rate detection unit 2 including electrodes attached to the chest, and the acceleration is detected by the acceleration detection unit 1 in the wristwatch type calorimeter body.
The heart rate data measured by the heart rate detection unit 2 is sent to the wristwatch type calorie consumption meter main body by wire, and the calorie consumption is calculated by the calculation unit 3 in the calorie consumption main body and displayed on the display unit 4. . The heart rate data measured by the heart rate detector 2 may be wirelessly transmitted to the calculator 3 of the calorimeter main body. Moreover, if the pulse rate is obtained by detecting the pulse wave by providing an optical sensor for detecting the pulse group of the person to be measured on the main body of the calorimeter, it is possible to obtain the heart rate from the pulse rate. The function of can be accommodated in the wristwatch type calorie consumption meter main body, and the wearing, carrying, display confirmation and the like become easier.

しまうことがあった。(Embodiment 5) By the way, in the calorie consumption meter of Embodiment 2, when the physical activity level determining means determines the physical activity level from the acceleration, it does not matter whether the user is exercising and the physical activity level is high. Instead, the physical activity may be judged as "small". For example, in the case of pedaling exercise on a bicycle, even though the physical activity is large, the heart rate fluctuation and the calorie consumption are large, the acceleration is small due to the nature of the pedaling exercise, so the physical activity is “small”. Since the calorie consumption is determined from the heart rate based on the determined regression line A, the error from the actual calorie consumption may increase.

ロリとの比例関係から算出される。The basic structure of the calorie consumption meter of this embodiment is substantially the same as that of the second embodiment, and is characterized in that it is difficult to detect acceleration according to physical activity, and it is possible to accurately determine the magnitude of physical activity. The point is that a dedicated mode for obtaining the calorie consumption at the time of exercise that cannot be performed and a mode selection unit for selecting this dedicated mode are provided. With this calorie consumption meter, the dedicated mode should be selected in advance when pedaling the bicycle. When this dedicated mode is selected, the acceleration detection unit 1 stops detecting the acceleration, and the physical activity determination means fixes the physical activity at “large”,
The calorie consumption is calculated from the proportional relationship between the heart rate and the calorie consumption when the physical activity is “high”.
