DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body fat meter in which a pedometer is integrated, and which can be carried on a daily basis.

[0002]

2. Description of the Related Art It is necessary to maintain an appropriate amount of fat in the body in order to prevent adult illness and the like and to maintain a healthy state. Calories) and balance of basal metabolism, exercise, physical activity, and digestion and absorption of food. Exercise such as walking and running can be easily and routinely used as a means for consuming calories. Also,
There are devices that can know the relationship between these exercises and the amount of exercise and calorie consumption accompanying the exercise, and various devices that can know the amount of fat in the body.

[0003] Among these devices, there is a pedometer (generally referred to as a "pedometer") as a device which can easily know the amount of exercise and calorie consumption accompanying walking.
This pedometer is a device that counts the number of steps of walking or running by being attached to the waist of the body or the like, and is capable of estimating calorie consumption based on the number of steps and required personal data such as step length, weight, age and the like. There are some. Also,
In some cases, the time required for walking and running is measured to determine an average speed for a certain period of time, and calorie consumption is estimated based on the average speed.

On the other hand, there is a body fat meter as an instrument capable of measuring the body fat weight or body fat percentage of the body. This body fat meter
The body fat weight or body fat percentage can be obtained from bioelectrical impedance, which is the impedance of a human body measured by bringing an electrode into contact with a body part, and necessary personal data such as weight, height, and age.

Further, there is a training device using a bicycle ergometer. According to this device, a menu including exercise corresponding to a certain amount of exercise or calorie consumption is determined, and training is performed according to this menu. In addition, there is an apparatus in which an electrode is provided on a handle portion of such a training apparatus so that a body fat percentage can be measured.

[0006]

According to the above pedometer, it is possible to know the amount of exercise and calorie consumption based on the measured number of steps, and to perform exercise such as walking according to the target amount of exercise. You can, but you can't even know about the changes in body fat that accompany this.

Further, the conventional body fat meter can know the body fat percentage and the body fat weight, but cannot know the amount of exercise and the like, and cannot know the relationship between the body fat and the amount of exercise.

[0008] Further, even with a training device using a bicycle ergometer, it is not possible to know the relationship between the change in body fat due to exercise and the amount of exercise. Also,
This training device is installed and used in a sports center or the like, and cannot be easily carried and used by individuals on a daily basis.

Therefore, the present invention provides a body fat meter with a pedometer that can be easily carried and used on a daily basis and that can be used to know the relationship between changes in body fat due to exercise and the amount of exercise. The purpose is to do.

[0010]

In order to solve the above-mentioned problems, a body fat meter with a pedometer according to the present invention comprises an operation unit for inputting personal data including weight data of a subject; A pair of current path forming electrodes for forming a current path in the body of the subject, a pair of voltage measurement electrodes for measuring bioimpedance which is the impedance of the human body in the current path, a body fat percentage of the subject, etc. A display unit that displays data of the subject, a storage unit that stores data such as personal data and body fat percentage of the subject, and a calculation unit that calculates a body fat percentage based on the personal data and bioimpedance. A pedometer for measuring the number of steps accompanying exercise such as walking of the subject, the main body is formed portable, and configured to display at least data of the number of steps measured by the pedometer. Yes Section 1).

Thus, in the body fat meter with a pedometer according to the present invention, the body fat can be measured, and the amount of exercise such as the number of steps accompanying the exercise such as walking can be measured. Since the body fat meter with a pedometer according to the present invention is formed to be portable and can be carried on a daily basis, it is possible to easily measure body fat and the amount of exercise accompanying walking or the like at any time.
Then, by measuring body fat before and after walking, it is possible to easily know at any time a change in body fat with respect to exercise accompanying walking or the like.

The body fat meter with a pedometer can store the data of the number of steps, and the first body fat ratio and the pedometer after the first body fat ratio is measured. And a body fat change calculating means for calculating a change in body fat with respect to the data on the number of steps based on the number of steps measured by the step (2) and the second body fat percentage further measured thereafter (claim 2). The change in body fat determined from the first body fat percentage and the second body fat percentage before and after exercise such as walking is calculated as a change with respect to the amount of exercise grasped by data on the number of steps measured by a pedometer. , It becomes possible to evaluate. This makes it possible to more clearly understand the effect of exercising such as walking to consume body fat.

In calculating the change in body fat with respect to the data on the number of steps, a difference between the first body fat rate and the second body fat rate, that is, a body fat rate difference is obtained. Some find the difference ratio. In addition, other than calculating the amount of exercise such as walking distance from the step count data and calculating the ratio of the body fat percentage difference to the exercise amount, calculating the body fat amount corresponding to the body fat percentage difference, and calculating the calorie consumption from the step number data Such as the body fat mass ratio, such as the change in body fat before and after walking, determined from the difference between the first body fat percentage and the second body fat percentage, with respect to the amount of exercise determined based on the step count data Various calculations for evaluating changes in body fat are included.

[0014] Further, the body fat meter with a pedometer is provided with a body fat percentage measurement instructing means for instructing the measurement of the first body fat percentage and the second body fat percentage, and the termination of the measurement of the first body fat percentage. Is detected, when the end of the measurement of the number of steps is detected, the body fat percentage measurement instructing means is provided with a second step. Instruct the measurement of the body fat percentage, the body fat change calculation means,
The apparatus may be configured to determine the change in the body fat based on the measured first and second body fat percentages and the step count data (claim 3).

Thus, the measurement of the first body fat percentage before the start of the exercise such as walking, the measurement of the step count data associated with the walking and the like, and the measurement of the second body fat percentage after the exercise are performed. Since the measurement can be reliably performed without making a mistake or the like, it is possible to reliably measure the change in body fat during walking or the like.

The body fat change calculating means calculates calorie expenditure consumed by exercise such as walking of the subject based on the data on the number of steps, and calculates a change in body fat with respect to the data on the number of steps. It is possible to obtain a fat consumption rate as a change in body fat with respect to consumed calories (claim 4). Thus, since the calorie consumption is calculated as the amount of exercise accompanying the number of steps based on the data of the number of steps, a change in body fat with respect to the calorie consumption expressed as the energy amount can be grasped. This is convenient because the change in body fat can be clearly associated with the intake food or the like via the consumed calories.

The body fat change calculating means may calculate the calorie consumption based on the subject's stride, the number of steps, and the weight data input through the operation of the operation unit. (Claim 5). That is, from these data, the calorie consumption, which is the amount of exercise consumed by the subject walking a certain distance or the like, can be obtained. The fat consumption rate can also be determined from the calorie consumption and the change in body fat (claim 5).

The fat consumption rate can be stored, and the calorie consumption is estimated from the stored fat consumption rate and a change in body fat obtained based on the body fat rate. The calculation can be performed (claim 6), while the change in body fat can be estimated from the fat consumption rate and the calorie consumption calculated based on the measurement of the step count data (claim 7). ).

The fat consumption rate thus obtained represents the rate of consuming body fat for a certain amount of exercise converted into calories consumed, and is specific to the subject's personal constitution. . Once the fat consumption rate can be obtained, the body fat consumed can be estimated from the measured calorie consumption and the fat consumption rate by measuring the calorie consumption accompanying exercise. . On the other hand, by measuring changes in body fat due to consumption of body fat, it is possible to estimate calorie consumption from the measured changes in body fat and the fat consumption rate.

In addition, the body fat change calculating means requires the number of steps, required to consume a certain amount of a target body fat,
The walking distance and the calorie consumption can be obtained based on the step count data, the calorie consumption and the fat consumption rate (claim 8).

Thus, when the subject wants to consume a certain amount of body fat, if this is set as a target value, the number of steps, walking distance, and consumption required to consume a certain amount of the body fat are set. You can know calories. This is convenient because the number of steps and the like can be used as a measure of exercise such as walking.

Further, the body fat meter with a pedometer is configured to measure the time after the measurement of the number of steps by the pedometer is started, and the body fat change calculating means detects the time from the data of the number of steps and the stride. It is also possible to determine the average moving speed from the distance moved by the person, the moving distance and the time required for the movement, and to calculate the calorie consumption accompanying the movement based on the average moving speed. Item 9).

Also, the body fat meter with a pedometer can measure the body fat percentage at a certain time interval after the start of a specific type of exercise such as walking, so that the first body fat percentage and the constant To perform a sequential comparison with the measured body fat percentage, after the start of the specific type of exercise, the difference between the first body fat percentage and the body fat percentage measured at regular intervals is The time until detection can be measured as the fat burning start time, and the fat burning start time can be stored together with the specific exercise type, and after the fat burning start time is stored, After the fat burning start time has elapsed since the start of the specific type of exercise, a change in the body fat with respect to the data of the number of steps measured by the pedometer may be obtained. (Claim 0).

According to the body fat meter with a pedometer, it is possible to obtain a change in the body fat with respect to the exercise amount based on the step count data after the consumption of the body fat itself after the fat burning start time has elapsed. .

That is, the consumption of body fat of the human body does not start immediately after the start of exercise such as walking, but after a certain period of time has elapsed after the consumption of glycogen and the like stored in the human body has started. You. Therefore, when it is desired to know the number of steps and calorie consumption corresponding to the direct consumption of body fat itself, the number of steps and calorie consumption after the consumption of body fat itself is started by corresponding to the mechanism of the human body consumption. It is necessary to know etc. The certain time until the consumption of body fat itself starts is unique based on the type of exercise such as walking and running, the constitution of the subject, and the like.

According to the body fat meter with a pedometer, such a fixed time can be obtained as the fat burning start time. And once the fat burning start time is determined,
After that, it is possible to know the relationship between the consumption of body fat itself and the number of steps, calories consumed, etc., which correspond directly to this.

Then, the body fat meter with a pedometer is used to determine the calorie consumption based on the data of the number of steps after the fat burning start time has elapsed, and to calculate the amount of body fat with respect to the calorie consumption after the fat burning starting time has elapsed. It may be configured to obtain a modified fat consumption rate that is a change (claim 11). With such a corrected fat consumption rate, it is possible to know a change in body fat with respect to calorie consumption, which leads to direct consumption of body fat itself.

Further, the body fat change calculating means may be configured to calculate an average value of the fat consumption rate determined a plurality of times (claim 12). It is also possible to configure so as to obtain the cumulative value of the mass consumption rate (claim 13).

The modified fat consumption rate can also be configured to calculate an average value of the corrected fat consumption rate obtained a plurality of times (claim 14).
It is also possible to configure so as to obtain the accumulated value of the values obtained a plurality of times (claim 15).

Further, the fat consumption rate or the corrected fat consumption rate may be stored together with incidental conditions such as a measured time zone. Specific examples of such incidental conditions include the type of exercise such as walking and running, the time period during which the exercise is performed, the state before and after a meal before performing the exercise, and the like.

The display section can be used also for displaying the step count data (claim 17), and the storage section can also be used for storing the step count data (claim 18). In this way, by using the display unit and the storage unit for functioning as a body fat meter also for functioning as a pedometer, the members can be shared, so the body fat meter with a pedometer can be made more compact. It becomes possible to.

Further, the main body of the portable body fat meter with a pedometer, which is formed so as to be portable, can be formed in a form comprising a pair of front and back surfaces and an end surface surrounding the outer periphery of the front and back surfaces. Item 19).

When the main body composed of the pair of front and rear surfaces and the end surface surrounding the outer periphery of the front and rear surfaces is a card type (claim 20), the main body is more compact and portable. Can be more enhanced.

Further, with respect to the pair of current path forming electrodes and the pair of voltage measuring electrodes, one finger of one hand of a subject can be brought into contact with one of the current path forming electrodes. A finger other than the one finger of the one hand can be brought into contact with one of the electrodes, and one finger of the other hand of the subject is contacted with the other one of the current path forming electrodes. And the other electrode of the other hand can be arranged on the main body such that a finger other than the one finger of the other hand can contact the other one of the electrodes for voltage measurement.
1). Thus, the bioimpedance of the subject can be measured through bringing each finger into contact with each of the four electrodes.

Further, four electrodes comprising the pair of current path forming electrodes and the pair of voltage measuring electrodes may be provided on either the front surface or the back surface of the main body.
2), any two of the four electrodes including the pair of current path forming electrodes and the pair of voltage measuring electrodes are provided on one of the front surface and the back surface of the main body, and the other two of the four electrodes are mounted on the main body. (Claim 23).

Further, four electrodes consisting of the pair of current path forming electrodes and the pair of voltage measuring electrodes may be arranged on the end face of the main body.

A plurality of operation keys that can be touched by a finger are provided on an operation section for inputting the personal data, and four operation keys including the pair of current path forming electrodes and the pair of voltage measurement electrodes are provided. All or part of the two electrodes can be used also as all or part of the operation keys.
5). As described above, when all or a part of the four electrodes are also used as the operation keys, the main body can be made more compact, so that portability can be further improved.

FIG. 2 shows a block configuration of the body fat meter 10.

The arithmetic processing unit 20 shown in FIG. 2 calculates the body fat percentage based on the bioelectrical impedance and the personal data, and calculates the amount of exercise and calorie consumption accompanying exercise such as walking and running. In addition, calculation is performed on the change in body fat with respect to the amount of exercise and calorie consumption. The arithmetic processing unit 20 includes an arithmetic unit 21 including a CPU and the like and a storage unit 22.
And

The storage unit 22 stores the impedance measurement unit 1
2, the measured value of the bioelectrical impedance measured via the electrodes 3a and the like and the body fat percentage obtained based on the measured value are also stored. In addition, the storage unit 22 also stores personal data such as the weight, height, and stride of the subject input through the operation of the data input unit such as the operation keys 4a. In addition, the number of steps counted by the pedometer constituted by the step number sensor 13 and the step number measurement unit 14 is stored in the storage unit 22, and the time measured by the clock 23 is also stored in the storage unit 22. ing.

Further, the storage unit 22 stores a body fat change calculation control routine. When the body fat change calculation control routine is executed, as will be described later, an instruction to measure the body fat percentage is given to the user of the body fat meter 10,
An instruction to start the measurement of the number of steps is issued, and a calculation of a change amount of body fat due to consumption of body fat due to exercise such as walking is also performed.

When this body fat change calculation control routine is executed, the impedance measurement by the impedance measurement unit 12 via the electrodes 2a and the like, and the state of operation of the start / end key 9 are performed. Can be detected.

Next, an example of the operation of the body fat meter 10 will be described with reference to FIGS. 3 and 4 using an example of how to use the body fat change amount accompanying walking or the like. By operating the switching key 8, a mode in which the body fat meter and the pedometer are combined is selected. Thus, the body fat change calculation control routine shown in FIG. 3 is executed. First, required personal data such as height, weight, age, gender, and step length are input (S1). Next, measurement of the bioelectrical impedance related to the body fat percentage of the subject is instructed (S2). Then, based on the instruction (S2, Y), the impedance is measured and stored (S3). Then, the first body fat percentage is determined based on the impedance measured in S3, and the first body fat mass (BFM1) is also determined (S4). The first body fat percentage and the first body fat amount are stored and can be displayed on the display unit 7 (S4).

The body fat amount determined in S4 can be calculated based on the body fat percentage, for example, by using a well-known calculation formula shown in JP-A-7-79938. Then, it is instructed whether to end the impedance measurement (S5). When the impedance measurement is completed (S5, Y), it is instructed whether or not to start counting the number of steps (S6). Then, based on the instruction (S6, Y), the subject operates the start / end key 9 to put the pedometer into a countable state. Thereby, the number of steps accompanying the walking of the subject is counted (S7).

Then, it is instructed whether or not to end the measurement of the number of steps (S8), and when the subject operates the start / end key 9 to stop the pedometer (S8, Y), the counting of the number of steps is stopped. Is performed (S9). Then, the counted number of steps is stored as the number-of-steps data and can be displayed on the display unit 7 (S10). Further, the calorie consumption (K) in the body of the subject accompanying the exercise of the number of steps is calculated. The calculated calorie consumption is stored and can be displayed on the display unit 7 (S1).
0). The calorie consumption required in this S10 is
It is obtained as the product of the number of steps, the stride, the weight, and the unit calorie consumption (calories consumed per unit weight and unit walking distance).

Next, measurement of the bioelectrical impedance relating to the body fat percentage of the subject is instructed again (S11). Then, based on the instruction (S11, Y), the impedance is measured and stored (S12). Then, the second body fat percentage is calculated based on the impedance measured in S12, and the second body fat mass (BFM2) is also calculated (S13). The second body fat percentage and the second body fat mass can be stored and displayed on the display unit 7.

Next, the amount of change in body fat (ΔBFM) accompanying exercise such as walking is calculated by using BFM1 and BFM2 (S14). In addition, the amount of change in body fat can be stored and displayed on the display unit 7. Next, a fat mass consumption rate (ΔBFM / K) is calculated from the fluctuation amount (ΔBFM) of the body fat and the calorie consumption (K) (S15). This fat consumption rate is stored and can be displayed on the display unit 7 (S1).
5).

In the above description, as an example of obtaining a change in body fat before and after exercise, a method of obtaining the relationship between the calorie consumption calculated based on the step count data and the amount of change in body fat has been described. Other than this, it can be obtained as various data representing the relationship between the step count data and changes in body fat. For example, a relationship between the number of steps itself and a change in the body fat percentage before and after walking may be obtained. This is because it is possible to know how much the body fat percentage changes for a certain number of steps. Alternatively, the relationship between the number of steps and the amount of body fat may be obtained. That is,
It suffices if it is possible to know the relationship between the amount of exercise reflected in the data of the number of steps and the change in body fat based on the data.

In the body fat meter 10, the calorie consumption of the body can also be obtained from the walking speed (or running speed) which is the moving speed of the subject. S6 and subsequent steps S10 in the body fat change calculation control routine shown in FIG.
Is the procedure from S16 to S25 shown in FIG. 4, the calorie consumption of the body can be obtained from the walking speed. That is, it is instructed whether or not to start counting the number of steps (S16), and based on the instruction (S16,
Y), the pedometer can be counted by operating the start / end key 9 by the subject. Then, the counting of the walking time is started (S17), and the number of steps is counted (S18).

Next, it is instructed whether or not to end the measurement of the number of steps (S19). When the subject operates the start / end key 9 to stop the pedometer (Y in S19), the counting of the number of steps is started. The operation is stopped (S20). Then, the counted number of steps is stored as the number-of-steps data and can be displayed on the display unit 7 (S20). The counting of time is also stopped (S21). The counted time is the walking time required for the movement of the walking distance obtained later, and can be stored and displayed on the display unit 7 (S21).

Next, the walking distance, which is the moving distance of the subject, is determined (S22). This walking distance is calculated as the product of the number of steps and the step length. In addition, the average walking speed, which is the average moving speed, is calculated based on the walking distance obtained in S22 and the average walking speed.
21 is calculated from the walking time obtained in step 21 (S
23). Next, the energy consumption (unit calories (Kc
al / Kg / min)) is determined (S24). Next, calorie consumption is determined (S25). The calorie consumption is the unit calorie determined in S24, the walking time,
It is calculated as the product of the weight.

In storing the fat consumption rate in step S15, changes in body fat, such as the type of exercise such as walking or running, the time period during which the exercise was performed, and the state before and after eating before the exercise were performed. Can be stored together with the measured incidental conditions. The fat consumption rate may be displayed as a graph on the display unit 7 as a parameter under the incidental condition.

By storing the fat mass consumption rate in S15, the next time the measurement of the amount of change in body fat or the calorie consumption due to walking or the like is performed, one of them and the fat mass consumption rate are measured. , The other can be sought. Further, based on the fat consumption rate obtained in S15, the cumulative value of the fat consumption rate obtained in each measurement may be obtained, and the average value of the fat consumption rate measured a plurality of times may be obtained. May be obtained. Since the cumulative value of the fat consumption rate reflects the amount of body fat consumed cumulatively over a certain period of time, when planning a target of fat consumption over a certain period of time, the achievement of the target It is convenient for evaluating the degree. Further, since the average value of the fat consumption rate reflects the average fat consumption during a certain period, it is easy to grasp the average situation of fat consumption over a certain period.

Further, from the fat amount consumption rate stored in S15 and the number of steps and calorie consumption stored in S10, the number of steps, the walking distance, and the walking distance required for the target body fat consumption (target fat consumption) are calculated. The calorie consumption can also be calculated. Then, the target fat consumption can be set in advance before exercising such as walking, and the fact that the target fat consumption has been consumed by walking or the like is displayed on the display unit 7 or an alarm is issued by a buzzer. May be used.

In the above description, the body fat percentage is measured before and after the start of the measurement of the number of steps, and based on the two body fat percentages before and after walking and the step count data, the body fat percentage for walking and the like is measured. What is required for the change is explained. Here, the consumption of the body fat of the human body does not start immediately after the start of the exercise, but starts after a certain period of time has elapsed after the consumption of glycogen and the like stored in the human body has started.

Therefore, when it is desired to know the number of steps and calorie consumption corresponding to the direct consumption of body fat itself, the number of steps after the consumption of body fat itself has started since the body fat consumption mechanism has been started is determined in accordance with the mechanism of human body consumption. It is necessary to know the calorie consumption and the like. The relationship between the consumption of the body fat itself, the number of steps, the calorie consumption, and the like can be known by using, for example, the following procedure.

Before the measurement of the number of steps is started, the first body fat percentage is measured to determine the first body fat mass. Then, when the measurement of the number of steps associated with walking or the like is started, the body fat percentage is sequentially measured at fixed time intervals, and stored together with the time and the number of steps. The body fat percentage measured at such a fixed time interval and the first body fat percentage are sequentially compared until a difference is detected. When this difference is detected, the comparison is stopped. The detection of a difference from the first body fat percentage by the comparison means that the consumption of body fat has started. The time until such a difference is detected is the time required until the consumption of body fat after the start of walking or the like (referred to as “fat burning start time”).

The calorie consumption based on the number of steps measured after the lapse of the fat burning start time is directly linked to the consumption of body fat itself. From the second body fat mass, a corrected fat mass consumption rate with respect to the consumption of the body fat itself can be determined. Further, the fat burning start time can be stored together with the type of exercise such as walking or running. Then, when the measurement of the fat mass consumption rate is performed next time, the corrected fat mass consumption rate with respect to the consumption of the body fat itself may be obtained by using the fat burning start time according to the type of the exercise. Good.

As described above, since the body fat meter with a pedometer according to the present invention is portable, the body fat and the number of steps involved in exercise such as walking can be easily and routinely measured. . Then, it is possible to easily know the amount of body fat that has changed due to exercise such as walking, and the relationship between the amount of exercise and the amount of change in body fat.

In the body fat meter with a pedometer described above, various portable members other than those functioning as a pedometer and a body fat meter may be incorporated so as to be integrated. For example, a stopwatch, a night light lamp, a calculator, a lighter, a mechanical pencil, a tie pin, a thermometer, a range finder of a golf course, and the like may be incorporated, and thereby, it is possible to function as these incorporated members, which is convenient. It is. In addition, a portable pulse meter, blood pressure monitor, respirometer, thermometer, and the like can be integrated so as to be integrated with each other, and thereby it can be used as an exercise ability checker.
