Description

  The present invention relates to an activity amount measuring apparatus that measures usefulness such as walking and exercise of a living body using an acceleration sensor or the like and provides useful information.

  As a conventional device for measuring the amount of activity, there is a device that detects walking and movement mainly using a multi-axis acceleration sensor and calculates energy consumption and accumulated energy consumption at that time.

  In such an activity amount measuring device, the configuration has been improved so that walking and movement can be detected with high accuracy, and one of them is taking into account fluctuations in the pulse rate and accurately consuming energy. There is a device for calculation (for example, Patent Document 1).

  Also, to maintain motivation for walking and exercise, provide time-series graphs, suggest target values and achieve them (for example, Patent Document 2), or provide music to enjoy the exercise itself. There are some (for example, Patent Document 3).

In addition, an apparatus that determines and displays whether or not the current activity amount is in an appropriate range for the user has been proposed (for example, Patent Document 4).
JP-A-9-294727 JP 2003-180665 A JP 2003-305146 A JP2003-210439

  As described above, there are many devices that detect walking and movement and calculate the energy consumption from the total amount of activity as described above. However, what has been proposed in the past is mainly consumption improvement during activities by improving the sensor. Many are intended to be able to measure energy with high accuracy.

  Alternatively, it is intended to promote walking and exercise for the user by displaying graphs of useful information, for example, daily changes in energy consumption, from the results of the measured amount of activity and energy consumption.

  In this way, with the conventional activity amount measuring device, the aim is to improve the accuracy of the amount of activity and energy consumption, or simply perform changes in the measured activity amount and energy consumption as a visually distinctive display. is there.

  However, even if the daily energy consumption is displayed in a graph, such a device simply knows how much energy is consumed as a result of walking and exercising, and keeps the user interested for a long time. It may be neglected to measure and manage gait and movement with an activity measuring device.

  By the way, each human activity is not independent of each other, but each activity is a part of continuous operation. In other words, the activity at a certain point of time is influenced by the physical condition of the previous activity, especially if the activity (exercise) exceeds a certain level, even if the activity is suspended, the energy consumption will continue for a while. It was said that the state of increasing hyperactivity continued, and it was said that the energy consumption was high even when resting after exercise.

  However, it has been vaguely known in the past that such a situation may occur, but such characteristics are not particularly used, and the conventional activity measuring device has no activity amount / energy consumption. They were all aimed at increasing the accuracy of calculations.

  For people who need to manage energy consumption, such as dieting, it is not possible to understand at what point it is desirable to actively work in a long time of the day. There was no specific activity, and he concentrated on his free time. Such activities and exercises are not efficient because they require time for energy consumption, and miss the opportunity to consume energy efficiently in normal life. It was.

  The present invention has been made in view of these problems, and in an apparatus for detecting activities such as walking and exercising and calculating the energy consumption thereof, informs whether the energy can be efficiently consumed. This is to encourage the user to actively walk and exercise.

In the activity amount measuring apparatus of the present invention, an activity detection means for detecting a biological activity,
Activity amount calculating means for calculating the amount of activity of the living body based on the signal obtained from the activity detecting means;
Activity time measuring means for measuring the activity time of the living body based on the signal obtained from the activity detecting means;
Activity level determination means for determining the level of the calculated activity,
Energy consumption that determines whether the energy consumption in the next activity increases during the period when energy consumption in the next activity increases when activity below a certain level is detected for a certain period of time after an activity of a certain level or more has been continuously performed for a certain period of time An enhancement period determination means;
Informing means for notifying that it is in the energy consumption enhancement period is provided to inform the user that energy can be efficiently consumed.

  Further, in the activity amount measuring apparatus of the present invention, the content related to the energy consumption enhancement period notified by the notification means is the remaining time of the period, and allows the user to grasp the time during which the energy consumption enhancement state continues. To do.

  Further, the activity amount measuring apparatus of the present invention further includes energy consumption calculating means for calculating energy consumption based on the calculated activity amount, and notifies the user of the energy consumption.

  In the activity amount measuring apparatus of the present invention, the consumed energy calculated by the consumed energy calculating means is calculated so as to be higher than the consumed energy calculated in a normal state during the consumed energy promotion period. Is calculated accurately.

  Moreover, the activity amount measuring apparatus of the present invention further comprises body data acquisition means for acquiring the user's body data used for calculating the energy consumption from an external measuring instrument, thereby simplifying and accurately inputting the body data. The energy consumption is calculated.

  Further, in the activity amount measuring apparatus of the present invention, the energy consumption enhancement period determination means further changes the duration of the energy consumption enhancement period according to the time when the energy consumption enhancement period is reached, and the energy efficiency is improved. Accurately determine how long it can be consumed.

  The activity amount measuring apparatus according to the present invention is configured to notify the user that the energy consumption is in an increased state when it is determined that the conditions of a certain activity level and activity time are satisfied. Energy can be consumed efficiently in activities.

  In addition, if the activity amount measuring device of the present invention is used to manage energy consumption, it is not necessary to provide time for special exercise to consume energy, and it is efficient even in everyday life. It becomes possible to consume energy.

  Moreover, if it is the user who is managing the diet using the active mass measuring device of the present invention, the user can continue to be interested in the diet that requires continuous exercise and continue the diet. It becomes possible.

  The present inventor considers that if an activity of a certain level or more is performed for a certain period of time, even if the subsequent activity is weak, the energy consumption increases due to a state in which the basal metabolic rate is increased, and different activities are performed in advance. A total of four adult men and women conducted an experiment to measure energy consumption in subsequent activities.

  FIG. 1 is a graph showing a difference in energy consumption in activity intensity, and uses an average value of measurement data for all measurers.

  As the experiment contents, different activities (preceding loads) were performed for a certain period of time, and after resting temporarily after that, energy consumption was measured when the activities (subsequent loads) were performed under the same conditions. As a method for measuring energy consumption, breath collection was performed by the breath-by-breath method, and the measurement values were measured average values for the last three minutes in each measurement state. This is because the measured value is more stable after several minutes than when the activity was started.

  In the first measurement (during control conditions), the sitting position was maintained for 6 minutes without any special activity as the preceding load before the measurement, and an ergometer exercise with a load intensity of 60 W and RPM 60 (rotation / min) was performed as the subsequent load. . The value obtained by subtracting the amount of energy consumed per minute when the sitting position is resting, which is the preceding load, from the amount of energy consumed per minute at the time of starting load is a bar graph shown on the left side of FIG.

  Next, in the second measurement (in the middle strength condition), a medium strength load is given as a preceding load before the measurement. Here, using an ergometer, an exercise with a load intensity of 60 W and an RPM of 60 (rotation / min) was performed for 10 minutes. Thereafter, a 3-minute break (sitting position rest) was sandwiched, and an ergometer exercise of 60 W, RPM 60 (rotation / min) was performed as a subsequent load in the same manner as in the first measurement. A value obtained by subtracting the amount of energy consumed per minute during medium-intensity exercise, which is a preceding load, from the amount of energy consumed per minute during the subsequent load is the bar graph shown in the middle of FIG.

  Next, in the third measurement (during high strength conditions), a high strength load is applied as a preceding load before the measurement. Here, using an ergometer, a load intensity of 110 W and an RPM of 60 (rotation / min) were performed for 10 minutes. Thereafter, a 3-minute break (sitting position rest) was sandwiched, and an ergometer exercise of 60 W, RPM 60 (rotation / min) was performed as a subsequent load in the same manner as in the first measurement. The value obtained by subtracting the amount of energy consumed per minute during high-intensity exercise, which is the preceding load, from the amount of energy consumed per minute during the subsequent load is the bar graph shown on the right side of FIG.

  From FIG. 1, it can be seen that the energy consumption under the medium strength condition and the energy consumption under the high strength condition are higher than the energy consumption during the control condition (rest before measurement). Further, when the energy consumption under the medium strength condition is compared with the energy consumption under the high strength condition, the energy consumption under the high strength condition is higher. That is, from these results, it can be said that the amount of energy consumed in a certain activity situation is influenced by the previous activity, and the higher the previous amount of activity, the higher the amount of energy consumed in the subsequent activity.

  As described above, the present inventor has described the relationship between the energy consumption in a certain state and the effect of the previous activity from the experimental results of several subjects, but this has also been confirmed in other subjects. It is considered universally applicable to the general public. Also academically, it is known that certain activities affect resting metabolism in subsequent activities. Therefore, if a certain level or more of exercise is performed before a certain activity, the resting metabolic rate after that increases, and it is considered that the energy consumption increases due to the influence.

  In relation to the above, even if the subsequent activity has the same activity intensity and activity time as the previous activity, the energy consumed during the subsequent activity is the previous (preceding) if the time interval from the previous activity is within a certain time. More energy is consumed by the product of the energy consumption of the activity (load). Therefore, the period during which the effect of energy consumption due to the preceding load remains is set as a diet recommended period, and the information is provided to the user.

  Therefore, in the present invention, when an activity of a certain intensity and a certain period of time is carried out, and then the activity amount is low, an increased state in which the amount of energy consumption increases only by slightly increasing the activity amount ( By notifying the user that there is a diet chance), it is possible to increase energy consumption, and to have an interest in exercise and diet. As a result, as long as a user takes care of a certain activity pattern, the user can efficiently consume energy with a smaller activity intensity and activity time.

  In the activity amount measuring apparatus according to the present invention, the activity of the living body is detected, the current activity state is determined, and the subsequent desired activity is instructed based on the previous activity state. As a result, the calculation of the energy consumption in the activity is not an independent entity but a series of activities, and it is possible to estimate the energy consumption more suited to life.

  An embodiment of the present invention will be described with reference to the drawings. FIG. 2 is an external view of the activity amount measuring apparatus 1 of the present invention.

  The activity amount measuring apparatus 1 includes an input device 3 including a display device 2 as notification means, an up switch 3a, a down switch 3b, a determination switch 3c, and a power switch 3d as input means. The activity amount measuring apparatus 1 is carried by a user in a pocket or bag of clothes.

  FIG. 3 is a block diagram showing an internal connection state of the activity amount measuring apparatus 1.

  A signal from the acceleration sensor 5 which is an activity detection means for detecting the activity of the living body is amplified by the amplifier 6 and converted from an analog signal to a digital signal by the A / D converter 7.

  The A / D converter 7 is connected to the arithmetic and control unit 10. The arithmetic control device 10 performs various calculations relating to control of each element and data, and includes an activity amount calculating means, an activity time measuring means, an activity amount level determining means, an energy consumption acceleration period determining means, and an energy consumption calculating means. It is.

  A display device 2 for displaying various information such as input information and measurement results, an input device 3 comprising an up switch 3a, a down switch 3b, a decision switch 3c, and a power switch 3d, a power supply device 11 for supplying power to each element, A storage device 12 that stores various types of measurement data and a data reception unit 13 that is a body data acquisition unit that transmits and receives various types of measurement data to an external device are also connected to the arithmetic and control unit 10.

  Next, operation | movement of the active mass measuring device 1 of this invention is demonstrated using the flowchart shown in FIGS.

  When the power switch 3d is pressed, the activity amount measuring apparatus 1 is turned on, and each block in the apparatus is initialized (step S1).

  Here, a message for confirming whether personal information has already been registered is displayed on the display device 2. When the user registers personal information, the user selects a registration item using the up switch 3a and the down switch 3b on the selection screen displayed on the display device 2, and presses the decision switch 3c to select the personal information. Registration mode (step S2).

  When registering personal information, the user uses the up switch 3a and the down switch 3b to change the item items and numerical values displayed on the display device 2, and determines / registers the information with the determination switch 3c. To go. The user's sex, age, and height are input by such an input method (steps S3 to S5).

  When the registration of personal information is completed, a list of input items is displayed on the display device 2. If re-input is selected here, the process returns to step S3 and personal information is registered again (step S6).

  When the registration of the personal information is completed, the body composition index is received, and the display device 2 displays that data is received from the external measuring instrument (step S7).

  The user measures body composition such as body fat percentage, muscle mass, lean mass, and basal metabolic rate with a body composition meter 20 shown in FIG. 9 provided separately from the activity amount measuring apparatus 1. The body composition meter 20 includes current supply electrodes 21a and 21b and voltage measurement electrodes 22a and 22b on the upper surface, and a measurement switch 23 on the side surface.

  The user presses the measurement switch 23 to bring the right foot into contact with the current supply electrode 21a and the voltage measurement electrode 22a and bring the left foot into contact with the current supply electrode 21b and the voltage measurement electrode 22b. The body composition meter 20 measures body weight and bioelectrical impedance, and calculates body composition such as body fat percentage, muscle mass, and lean mass. Note that calculation of body composition such as body fat percentage, muscle mass, lean mass, and basal metabolic rate by the bioelectrical impedance measurement method is a known technique and will not be described.

  On the display device 2 of the activity amount measuring apparatus 1, a display instructing that the activity amount measuring apparatus 1 and the body composition meter 20 are brought close to each other and the decision switch 3c is pressed is displayed. When the user presses the decision switch 3c according to the instruction, the body composition data is received by infrared communication (step S8).

  A data transmitter 24 is provided on the front side of the body composition meter 20, and an issue diode is provided inside the data transmitter 24. The body composition data measured from here is transmitted by an infrared signal. A photodiode is provided inside the data receiving unit 13 of the active mass measuring apparatus 1 to receive the transmitted infrared signal of the body composition data.

  When the body composition data is normally received, the completion of the reception is displayed on the display device 2, and the activity detection by the acceleration sensor 5 is started (step S9). At this time, measurement of a certain time is started using a timer in the arithmetic and control unit 10. Here, two seconds are measured as an interval (step S10). In the activity amount measuring apparatus according to the present embodiment, the activity amount at the time interval when 2 seconds is set as a certain time is calculated. That is, the calculated amount of activity is a value every 2 seconds.

  When 2 seconds have elapsed, the timer is reset (step S11), and it is determined whether the current state is a state where energy consumption is promoted (hereinafter, this state is referred to as a diet time) ( Step S12).

  If it is not during the diet time, normal calorie consumption calculation is performed (step S13), and if it is during the diet time, calorie consumption peculiar to that period is calculated (step S14).

  After the calorie consumption calculation is performed in step S13, it is determined whether the diet time is reached (step S15).

  When the display switching is determined (step S16) and the power switch 3d is pressed, the power is turned off (step S17). Otherwise, the process returns to the detection of the activity amount by the acceleration sensor 5 in step S9. The detection of the amount of activity will continue.

Next, the energy consumption calculation routine in step S13 will be described.
The items calculated here are as follows.
・ Instant life activity intensity (step S21)
-Instantaneous energy consumption (step S22)
-Cumulative life activity intensity (step S23)
・ Cumulative energy consumption (step S24)

1-1) Instantaneous life activity intensity (instantaneous PAL: Physical Activity Level)
Although the activity data from the acceleration sensor 5 is sequentially stored in the storage device 12, the instantaneous PAL is calculated from the activity data for the current 2 seconds.
Instantaneous PAL = a ₁ × (sum of absolute values of acceleration per 2 seconds) + b ₁ × (body composition data) + c ₁
Here, a ₁ and b ₁ are coefficients, and c ₁ is a constant. The body composition data is a value calculated from data such as body fat percentage, lean mass, muscle mass, sex, and age, and uses data that is input and measured in advance. As a result, the activity intensity for 2 seconds is calculated based on the user's physique.

1-2) Instantaneous energy consumption (instantaneous EE: Energy Expenditure)
The instantaneous PAL calculated in step S21 is used to calculate based on the following formula.
Instantaneous EE = basal metabolic value × instantaneous PAL + c ₂
Here _{c 2} is a constant. The basal metabolism value uses data measured by the body composition meter 20.

従ってここで算出される累積ＰＡＬとは、測定している全期間における平均の瞬時ＰＡＬの値である。 1-3) Cumulative life activity intensity (Cumulative PAL: Physical Activity Level)
The current instantaneous PAL calculated in step S21 and the current instantaneous PAL stored in the storage device 12 are calculated based on the following equation.

Therefore, the cumulative PAL calculated here is the value of the average instantaneous PAL over the entire period being measured.

1-4) Cumulative energy consumption (Cumulative EE: Energy Expenditure)
Using the instantaneous energy consumption calculated in step S22 and the accumulated energy consumption up to that day stored in the storage device 12, the calculation is based on the following equation.
Cumulative EE = Σ Instantaneous EE
Therefore, the cumulative EE calculated here is a value of the sum of instantaneous EEs over the entire period being measured.

Next, the energy consumption calculation routine in step S14 will be described.
This is different from the calculation of energy consumption in step S13 described above, and is the calculation of energy consumption in a state where the efficiency of energy consumption is increased by the preceding activity.
The items calculated here are as follows.
・ Instant life activity intensity (step S31)
-Instantaneous energy consumption (step S32)
-Cumulative life activity intensity (step S33)
・ Cumulative energy consumption (step S34)

2-1) Instantaneous life activity intensity (instantaneous PAL: Physical Activity Level)
Although the activity data from the acceleration sensor 5 is sequentially stored in the storage device 12, the instantaneous PAL is calculated from the activity data for the current 2 seconds.
Instantaneous PAL = a ₃ × (sum of absolute values of acceleration per second) + b ₃ × (body composition data) + c ₃
Here, a ₃ and b ₃ are coefficients, and c ₃ is a constant. The body composition data is a value calculated from data such as body fat percentage, lean mass, muscle mass, sex, and age, and uses data that is input and measured in advance. As a result, the activity intensity for 2 seconds is calculated based on the user's physique.

2-2) Instantaneous energy consumption (instantaneous EE: Energy Expenditure)
The instantaneous PAL calculated in step S31 is used to calculate based on the following equation.
Instantaneous EE = (basal metabolic value x instantaneous PAL)
+ B ₄ × (average instantaneous PAL during preceding activity × preceding activity time) + c ₄
Here, b ₄ and c ₄ are constants. The basal metabolism value uses data measured by the body composition meter 20. The instantaneous EE calculated here is different from the instantaneous EE calculated in step S22, and energy consumption is added by the influence of the preceding activities.

従ってここで算出される累積ＰＡＬとは、測定している全期間における平均の瞬時ＰＡＬの値である。 2-3) Cumulative life activity intensity (Cumulative PAL: Physical Activity Level)
The current instantaneous PAL calculated in step S31 and the current instantaneous PAL stored in the storage device 12 are calculated based on the following equation.

Therefore, the cumulative PAL calculated here is the value of the average instantaneous PAL over the entire period being measured.

2-4) Cumulative energy consumption (Cumulative EE: Energy Expenditure)
The instantaneous consumption energy calculated in step S32 and the accumulated consumption energy up to that day stored in the storage device 12 are used to calculate based on the following equation.
Cumulative EE = Σ Instantaneous EE
Therefore, the cumulative EE calculated here is a value of the sum of instantaneous EEs over the entire period being measured.

  Next, the diet time determination routine in step S15 will be described. Note that the activity elapsed timer and the activity pause timer described later are provided in the arithmetic and control unit 10.

  In the diet time determination routine, a determination is made as to whether or not the energy consumption increase period is reached. This determination is an energy consumption acceleration period (diet time) when the amount of preceding activity is above a certain level, the amount of activity lasts for a certain amount of time, and then a low amount of activity continues for a certain amount of time. It is determined that

  In order to detect whether or not an activity of a certain level or more is being performed, the arithmetic and control unit 10 determines whether or not the current acceleration data obtained from the acceleration sensor 5 exceeds a predetermined value (first threshold) (step) S41).

  Here, if the first threshold value is exceeded, it is checked whether or not the activity pause timer that counts the time when the activity of a certain level or more is paused, and the continuous check count number is incremented by 1 (step) S42). Here, it is checked whether the activity count of a certain level or more is being performed while the activity stop timer is activated, whether the check count number exceeds a certain number, or here exceeds five times (step S43). If it is exceeded, the activity inactivity timer is cleared because the activity inactivity has occurred for a moment and the activity inactivity timer is cleared (step S44).

  Next, it is determined whether or not the activity continuation timer that measures the duration of the activity of a certain level or more is activated (step S45). If the activity continuation timer is not activated, the activity of a certain level or more is determined. Counting is started to measure the duration time (step S46).

Next, it is determined whether the activity above a certain level is higher than the higher level (second threshold) (step S47). This is because the activity of a certain level or more is determined as a condition of the preceding activity, but the duration of the energy consumption enhancement period in the subsequent activity changes depending on the amount of activity, although it is above a certain level. Therefore, if it is less than or equal to the second threshold, the energy consumption increase period is short and the diet time is + t ₁ second (step S48). If the second threshold is exceeded, the energy consumption increase period becomes longer. The diet time is set to + t ₂ seconds (step S49). Here, of course, t ₁ <t ₂ .

  Next, it is checked whether or not the state where the activity level, which is a condition for reaching the diet time, has exceeded a certain value has passed the minimum necessary time (step S50). Here, it is checked whether 5 minutes have elapsed since the activation of the activity continuation timer. When the activity continuation timer has passed 5 minutes, it is determined that the condition for the preceding activity continuation time is satisfied (step S51).

If the acceleration data does not exceed the first threshold value in step S41, it is checked whether or not the activity of a certain level or more has ended and the activity has been paused for a certain time. Here, the determination is made based on whether the inactivity timer has reached a certain time or more.
First, it is checked whether or not the preceding activity duration condition is satisfied (step S52).

  Here, when the preceding activity duration condition is satisfied, the time after the end of the activity of a certain level or more is checked. It is checked whether the inactivity timer is activated (step S53). If it is not activated, the activity inactivity timer is activated (step S54).

  If the inactivity timer is activated in step S53, it is checked whether the inactivity timer has passed a certain time. Here, it is checked whether 3 minutes have passed (step S55). When 3 minutes have elapsed, that is, when YES is determined in step S53, it is a case where the duration of the preceding activity of a certain level or higher is satisfied, and the state where the activity level has subsequently decreased has elapsed for a certain time. This state is a state where energy consumption in the subsequent activities can be increased. In other words, it can be said that the diet time is reached.

  If the diet time condition is satisfied, the activity continuation timer and the activity suspension timer are once cleared (step S56).

Further, as a calculation of the diet time, it is checked using the clock function in the arithmetic and control unit 10 whether the current time is in the afternoon (step S57). Here is the current time in the case of the afternoon, adding the t ₃ seconds to diet time (step S58). This is usually said that the body's resting metabolic rate is higher in the afternoon than in the morning. For this reason, it is thought that the afternoon is also more effective during the energy consumption enhancement period of the present invention. Therefore, in this embodiment, when the time determined to be the diet time is afternoon, + t3 seconds is added to the diet time.

Next, the diet time is calculated. The calculation of the diet time is a total value of the times t ₁ and t ₂ added in steps S48 and S49 and the time t ₃ when it is determined to be added in step S58 (step S59).

  The calculated diet time is displayed on the display device 2, and the countdown starts (step S60).

  Next, the display switching routine in step S16 will be described.

  FIG. 8 is a flowchart showing a display switching routine. FIG. 10 is a diagram showing a display state of the display device 2. In the activity amount measuring apparatus 1 in this embodiment, the display device 2 is divided into an upper main display section and a lower sub display section for display. The display content of the main display unit can be switched to three types of instantaneous consumption energy, accumulated energy consumption, and accumulated life activity intensity, and the instantaneous PAL and diet time are displayed on the sub display unit.

  FIG. 10A shows the instantaneous energy consumption, FIG. 10B shows the accumulated energy consumption, and FIG. 10C shows the accumulated daily activity intensity. FIG. 10D shows a state where the remaining time is 3 minutes as the diet time.

  It is checked whether the display content of the main display is instantaneous energy consumption (step S61). If the display content is instantaneous energy consumption, it is checked whether the down switch 3b is pressed (step S61). S62). If the button is not pressed here, the display of instantaneous energy consumption is continued (step S63). If the button is pressed, the display is switched to the display of accumulated energy consumption (step S64).

  In step S61, when it is determined that the display content of the main display unit is not instantaneous energy consumption, it is determined whether the display content is cumulative energy consumption (step S65). If the display content is not cumulative display energy, the cumulative life activity intensity is displayed on the main display unit.

  If the accumulated energy is displayed on the main display unit in step S65, it is checked whether the down switch 3b is pressed (step S66). If it is not pressed here, the display of the accumulated energy consumption is continued (step S67), and if it is pressed, the display is switched to the display of the accumulated life activity intensity (step S68).

  If the accumulated energy consumption is not displayed on the main display unit in step S67, the accumulated life activity intensity is displayed. Here, it is checked whether the down switch 3b is pressed (step S69). . If it is not pressed here, the display of the accumulated life activity intensity is continued (step S70), and if it is pressed, the display is switched to the display of instantaneous energy consumption (step S71).

  Therefore, in this display switching routine, every time the down switch 3b is pressed, the display content of the main display unit is switched in the order of instantaneous energy consumption, cumulative energy consumption, and cumulative life activity intensity.

  In the above, one embodiment of the present invention has been described. Here, an index of body composition such as body fat percentage and basal metabolic rate is measured by an external measuring instrument called a body composition meter 20, and consumption is obtained by receiving the measurement data. Although the configuration is such that data used for energy calculation is acquired, a configuration in which data is directly input by switch input may be employed.

  Alternatively, the communication method is not limited to infrared, and communication using radio waves or wired data communication may be used.

  Although not shown in the embodiment of the present invention, the activity amount measuring device is provided with a buzzer and an LED, and when it is in the energy consumption enhancement period, the buzzer is sounded or the LED blinks. If it is the structure which notifies that, it will become easy for a user to understand that it is in the state, and to be easy to use.

  Further, in the activity amount measuring apparatus in the present embodiment, the current time is checked using a clock function, and in the afternoon, the duration of the energy consumption enhancement period is added. It is good also as a structure which divides | segments into such a time slot | zone and changes the duration according to the time slot | zone determined as the consumption energy enhancement period. Alternatively, in addition to the distinction between morning and afternoon and the change according to the time zone, if the configuration is such that the duration of the energy consumption enhancement period is changed according to the elapsed time from the wake-up time, the determination becomes more suitable for the life of the user. .

  Further, in this embodiment, when it is in the consumption energy promotion period, the remaining time of the period is displayed, but what kind of activity should actually be performed in the consumption energy promotion period, For example, if it is configured to show activity contents such as walking, running, and stair climbing, it will be easy for the user to use.

  In addition to the calculation algorithm of energy consumption by the activity amount measuring apparatus shown in the present embodiment, it may be calculated as follows.

Information on physical characteristics of energy consumed during each activity (gender, age, height, weight, body fat percentage, basal metabolic rate, resting heart rate, etc., all of which are collectively referred to as Character: C), It is expressed by a function of activity intensity (Intensity: I), activity time (Duration: D), activity time (Time of Day: TD), and energy consumption (Energy Expenditure: EE) is calculated by the following equation.
EE = a * C + b * I + c * D + d + TD * e
(However, a, b, c, d, and e are constants.)

This formula itself is not different from the formula generally used to calculate energy consumption. However, as described above, the calorie consumption at a certain point in time is affected by the previous activity, and the consumption during the subsequent activity is calculated. For energy (Post Energy Expenditure: PEE), activity intensity, activity time, time interval between previous activities (Interval Time: IT), activity intensity in later activities (Post Intensity: Po_I), activities Considering time (Post Duration: Po_D) activity time (Post Time of Day: Po_TD), it is expressed by the following equation.
PEE = f × C + g × EE + h × IT
+ I * Po_I + j * Po_D + k * Po_TD + l
