Hereinafter, the exercise amount measuring device of the present invention will be described based on embodiments.

FIG. 1 is a block diagram showing the overall configuration of the exercise amount measuring device according to one embodiment. This exercise amount measuring device is basically the same as a conventional one except for various arithmetic functions and display forms. An acceleration sensor 1 which is attached to a human body and detects body movement, and a signal detected by the acceleration sensor 1 Amplifying circuit 2 for amplifying, A / D converting circuit 3 for converting the amplified signal into a digital signal, function of calculating exercise amount based on the input digital signal, estimated calorie consumption for a predetermined period (for example, one day) , A target target calorie calculation function for calculating a remaining target calorie, a target exercise amount calculation function for calculating a target exercise amount desired for the human body to consume for a predetermined period (one day), and a life activity index from the actually measured exercise amount. MPU 4 having a function of calculating a life activity index, a display (display unit) 5 for displaying gender, age, exercise amount, life activity intensity, etc., a power ON / OFF switch, and a display type Comprising a select switch, a switch 6 comprising a switch for inputting a gender, age, etc., and a power supply circuit 7 to select.

In this exercise amount measuring device, the amount of exercise, the intensity of daily activity, and the like are calculated by various arithmetic functions. The calculation requires a basal metabolic rate, and there are various methods for obtaining the basal metabolic rate. ). That is, the basal metabolic rate B is
B = B _S × S (1)
B _S : Basal metabolic standard value per 1 m ^{2 of} body surface area (kcal / m ² / hour)
S: Body surface area (m ² )
= (Weight / kg) ^0.444 x (height / cm) ^0.663 x 0.008883
Is required. However, the equation (1) is limited to age of 6 years, also B _S represents the different values by sex, age, a "dietary requirements of the Japanese (5th Revision)" It can be determined from Table II-1 [see FIG. 2 (table of basal metabolic reference values depending on gender and age) and FIG. 3 (graph showing relationship between age and basal metabolic reference values)].

On the other hand, the calculation of the life activity index is performed as follows. The total daily energy metabolism (A) is the energy consumed by exercise and the like (B · 基礎), the basal metabolism (B), and the metabolism by the specific dynamic action (0.1 · A; (Energy required to decompose and absorb) is given by the following equation (2). (However, χ indicates the life activity index)
A = B · χ + B + (1/10) A (2)
Transforming this equation,
χ = [(9/10) × (A / B)]-1 (3)
Therefore, it is sufficient to use the exercise amount actually measured as the total energy metabolism A and the basal metabolism calculated by calculation as the basal metabolism B.

The calculated life activity index is classified into, for example, four levels according to the life activity intensity as shown in FIG. 4, so that it is possible to know the level of exercise. In the ranking of FIG. 4, the living activity intensity I is small and the living activity intensity IV is large. Of course, the ranking need not be limited to four levels, but may be three or less, or five or more.

On the other hand, the target exercise amount is calculated with the above-mentioned life activity index 目標 as a target. In this case, the life activity index χ is set to 0.5 as an appropriate value, and the above equation (2) is used. That is, the target exercise amount A is
A = B · χ + B + (1/10) A
Therefore, A = (10/9) · (1 + χ) · B
And χ = 0.5,
A = 1.67 × B (4)
And the target exercise amount A can be calculated.

Next, the display mode of the display screen of the display 5 will be described. First, in the example shown in FIG. 5, the display screen is divided into an upper part 10 and a lower part 11, and the amount of exercise (total calorie consumption, kcal) is displayed in numerical values in the upper part 10, and the average of the past week and one week is displayed in the lower part 11. Is displayed as a bar graph. The activity intensity is divided into three stages of I (light), II (moderate), and III (slightly heavy), and II (moderate) is set as the target level. In this display mode, the amount of daily activity (total calorie consumption) and activity intensity are calculated at the end of the day and are automatically displayed. Also, the calorie consumption of each day and the activity intensity of each day in the past week (7 days), the average calorie consumption of 7 days and the average activity intensity are displayed. In order to record the calorie consumption and activity intensity for one week, for example, an automatic memory function may be provided. According to this display mode, the tendency of exercise for the past week can be understood at a glance.

FIG. 6 shows a modification of the display mode shown in FIG. This display mode displays the total calorie consumption and the three-step activity intensity in the same manner as shown in FIG. 5, but the total calorie consumption is displayed on the right part 12 of the drawing, and the activity intensity is displayed on the left part 13 of the drawing. Each stage is represented by a different picture. For example, in FIG. 6A, the activity amount of the previous day's life is displayed, and the activity intensity of this activity amount is indicated as I (light). In FIG. 6B, the average total calorie consumption for 7 days is displayed, and it can be seen that the activity intensity is II (moderate). The record of the calorie consumption and the activity intensity for the past seven days can be called up every day by operating the switch 6 or the like.

FIG. 7 shows another display mode. In this display format, when you enter your gender, age, height, and weight, the target calorie expenditure that suits you is automatically set and displayed, and the achievement rate of the target calorie expenditure is displayed as a bar graph and picture. You. Here, the target calorie consumption and the total calorie consumption are displayed on the upper part 14 of the display screen, and the target achievement degree is displayed on the lower part 15. For example, if the target calorie consumption is 2400 kcal in FIG. 7, and if the calorie consumption is 2400 kcal as shown in FIG. 8A, the target achievement degree is 100%, and the bar graph and the picture are as shown in FIG. Is displayed. On the other hand, as shown in FIG. 8B, when the calorie consumption is 1528 kcal, the degree of achievement of the target is about 65%, so that the bar graph and the picture are displayed accordingly.

FIG. 9 shows still another display form. In this display mode, the target calorie consumption and the total calorie consumption are displayed in the upper part 16 of the display screen, and the exercise time required to reach the target calorie consumption is displayed in the lower part 17. Here, if gender, age, height, and weight are input, a target calorie consumption suitable for each person is set and displayed. In FIG. 9 (a), when the calorie consumption is 1928 kcal, exercise is performed for 106 minutes for "walking", 35 minutes for "running", and 59 minutes for "swimming" until the target calorie consumption is consumed. What should be done is displayed. After such exercise, calories are further consumed. When the calorie consumption reaches 2028 kcal as shown in FIG. 9 (b), "walk" and "run" until the target calorie consumption reaches the target calorie consumption. Indicates that it is sufficient to exercise for 25 minutes, and "swim" for 43 minutes. Thus, as the calories are consumed, the exercise time required to reach the target calorie consumption decreases, so that it is easy to know how much more exercise should be performed. In the example shown in FIG. 9, three types of exercise, “walk”, “run”, and “swim”, are shown. However, the present invention is not limited to this, and is shown with more types of exercise. Is also good. For example, ball games such as bicycles, tennis, soccer, and baseball may be added as appropriate.

Next, an example of the overall operation of the above-described exercise amount measuring device will be described with reference to the flowcharts of FIGS. First, the power of the apparatus is turned on [step (hereinafter, referred to as ST) 1], and the sex, age, height, and weight of the subject are input (ST2). Then, the basal metabolic rate B is calculated by, for example, the above formula (1) (ST3), and the target exercise amount _AN is calculated from the obtained basal metabolic rate B by using the above formula (4) (ST4). The specified target momentum A _N is displayed on the display 5 as described above (ST5). Here, it is determined whether or not the start switch for starting the measurement is pressed (ST6). If NO, the process is in a standby state until the start switch is pressed, and if YES, the measurement is started (ST7). It goes without saying that the device is attached to the person to be measured before the measurement.

When the measurement is started, initial measurement is performed (ST8), and the acceleration sensor 1 captures data on the body movement of the subject (ST9). Next, it is determined whether or not the acquired data has been accumulated for 10 seconds (ST10). If NO, the data acquisition by the acceleration sensor 1 is continued, and if YES, the exercise amount A is calculated using the equation (2). (ST11), and the obtained amount of exercise A is displayed (ST12).

Subsequently, the difference (A _N -A) between the target momentum A _N and the actually measured momentum A is calculated and displayed (ST13), (A _N -A) / α ₁ is calculated, and the result is displayed. Is performed (ST14). Here, α ₁ is a constant 3.5 kcal / min when walking. That is, by calculating (A _N −A) / α ₁ , it is determined how much walking exercise should be performed until the target exercise amount is reached. When walking, the difference between the target exercise amount A _N and the measured exercise amount A is calculated. You just have to divide by 3.5 kcal / min. Then, in the next ST15, it is determined whether or not the select switch has been pressed, and if pressed, the calculation and display of (A _N -A) / α ₂ are performed (ST16). This α ₂ is a constant of 5 kcal / min when running, and it is required to determine how much exercise should be performed when running.

In ST17, it is determined whether 24 hours (1 day) has elapsed from the start of the measurement, and if not, the processing from ST9 to ST17 is continued. After 24 hours have passed, a life activity index χ is calculated from the above equation (3) (ST18), and the life activity index is determined by, for example, a life activity index and a life activity intensity set in advance as shown in FIG. (ST19). Subsequently, the data for 24 hours is updated, and the total exercise amount (total calorie consumption) and the daily activity intensity (activity intensity) for 24 hours are displayed (ST20). Then, the process returns to the initial measurement in ST8, Data acquisition for the next 24 hours is started. Of course, data for 24 hours is recorded in the memory.
