For this reason, it is important for health to prevent and eliminate obesity, and it is necessary to appropriately control the daily amount of exercise according to the degree of obesity to maintain a proper balance between calorie consumption and calorie intake. For that purpose, it is necessary to understand not only the body weight but also the body fat percentage, which is a barometer of obesity, and the amount of daily exercise.

[0003] From such a viewpoint, a portable fitness measuring instrument having both a body fat meter and an exercise amount meter has been commercialized. In these products, daily measurement data can be viewed. For example, it was not possible to record for a period, see changes in monthly or yearly units, or analyze the relationship between the amount of exercise and body fat percentage with a computer to obtain advice on an appropriate exercise method. In addition, the measurement data could not be exchanged with various people just by looking at the data, and the data could not be compared with other people. For this reason, it is difficult to maintain interest for a long time, and these products are rarely used effectively for a long time.

Accordingly, the present invention provides a conventional portable fitness measuring instrument by adding a portable / PHS communication function to exchange measurement data with various people or to transmit measurement data to a computer for a long period of time. It is intended to be able to provide support through recording and analysis programs.

The power / selection key K1 is used to turn on / off the power by long on for about 2 seconds and to switch input data and display data. The down key K2 inputs a number by decrementing the number by one each time the key is pressed. Each time the key is pressed, the up key K3 increases the number by one and inputs the number. When personal data such as gender, age (birth date), height, and weight are input, default values are displayed, and data input is performed while correcting the numerical values with the down key K2 and the up key K3. The confirmation key K4 confirms the input data, and when the confirmation key 4 is pressed, the flow shifts to the next input.

When measuring human body impedance, both arms are straightened at shoulder level, and as shown in FIG. 3, the power supply side electrodes E1, E1 and the detection side electrodes E2, E2 of the mobile momentum meter 1 are connected to the left and right sides. Tuck between your index finger and thumb. Thus, an AC voltage is generated between the left and right detection electrodes E2, E2, and the human body impedance between both hands is measured.

The AC voltage generated at the detection-side electrodes E2, E2 is applied to a changeover switch 23A, a bandpass filter 24, and a rectifier circuit 2.

7. Input to the CPU 14 via the I / O interface 16.

Before measuring the human body impedance, the output characteristics of the detection-side circuit are calibrated in advance in order to correct measurement errors due to aging and temperature characteristics of the elements constituting the human body impedance measurement circuit 2. That is, the two variables, that is, the human body impedance Z and the

FIG. 5 shows a block diagram of a momentum measuring circuit embodying the present invention. The exercise amount measuring circuit 3 includes a human body impedance measuring means 110 for measuring human body impedance via electrodes, and a personal data input means 120 for operating personal keys to input personal data of gender, age, height, and weight.
Body fat percentage calculating means 130 for calculating body fat percentage based on human body impedance and personal data; basal metabolic rate calculating means 140 for calculating basal metabolic rate based on personal data and body fat percentage; Exercise amount measuring means 15
It is composed of calorie expenditure calculating means 160 for calculating calorie expenditure for exercise based on 0 and the measured amount of exercise and basal metabolism.

FIG. 6 is a schematic diagram of a momentum meter of the momentum measuring means 150. The momentum meter 30 is a semiconductor pressure sensor 3
The pendulum 32 is swingably inserted into the first pressure port 31a. The pendulum 32 has a weight 32b attached to a distal end of a flexible elastic wire 32a, and a base end fixed to the silicon diaphragm 31b of the semiconductor pressure sensor 31. The weight 32b is
Due to the operation, the silicon diaphragm 31b swings in the 360 ° direction and is deformed to generate distortion. As a result, a resistance change occurs due to the piezoresistive effect in the strain gauge of the silicon diaphragm 31b, and a pulse-like bridge voltage whose amplitude changes according to the acceleration of the operation is generated. This pulse-like bridge voltage is amplified by a high gain amplifier to measure the acceleration and the number of times of the body movement. The momentum meter 30 detects a relative displacement of a weight attached to a spring with a strain gauge, detects a charge generated in proportion to the displacement of the weight by using a piezoelectric element instead of a spring, or detects a magnetic field. The induced electromotive force generated when the coil fixed inside the weight moves may be used to measure the acceleration and the number of body movements.

The basal metabolic rate calculating means 140 calculates the basal metabolic rate by the following formula based on the personal data and the body fat percentage. Basal metabolic rate = C0 x body weight x (100-body fat percentage) / 10
0 + C1 C0 = 24.0349 Women under 40 21.951 Women 40 and over 27.717 Men under 40 25.333 Men 40 and over C1 = 427.64 Women under 40 424.38 Women 40 and over 188.21 Men under 40 years old 243.28 Men over 40 years old If the exercise amount measurement circuit 3 is not provided with the human body impedance measuring means 110 and the body fat percentage calculating means 130, the body surface area is determined from the relationship between height and weight, and Alternatively, the basal metabolic rate may be determined by multiplying the reference basal metabolic rate per 1 m ^{2 of} the body surface area set for each age.

The calorie expenditure calculating means 160 calculates the average daily exercise intensity including the resting time based on the acceleration and the number of body movements measured by the kinetic meter 30 and the basal metabolic rate, and calculates the number of minutes for 24 hours. Multiply the number of calories consumed per day. Daily calorie consumption (kcal) = Average exercise intensity (kc)
al / min) × 1440 (min) The exercise intensity indicates the calorie consumption per minute consumed during exercise, and is calculated by the following formula. Exercise intensity (kcal / min) = (energy metabolic rate x basal metabolic rate + metabolic rate at rest) (kcal) / 1440
(Minutes) The energy metabolism rate indicates how many calories the basal metabolic rate consumes depending on the exercise intensity. For example, 2.0 when the exercise intensity is about a walk, and 3 when the exercise intensity is about a walk. .
The correlation between exercise intensity and energy metabolic rate is determined by actual measurement, such as 0, 5.0 for fast feet, and 7.0 for canters. The intensity of the exercise is proportional to the acceleration of the body movement measured by the kinetic meter 30, so that the value is estimated. When the momentum meter 30 does not detect a body motion, it is determined that the subject is at rest, and the energy metabolic rate at this time is calculated as zero. The metabolic rate at rest is 1.2 times the basal metabolic rate.

The mobile exercise meter according to the present invention is configured as described above. When measuring body fat, the power / selection key K1, the down key K2, the up key K3, and the enter key 4 are first operated. Enter personal data such as gender, age, height and weight. When entering personal data,
Each default value is displayed, and data is entered while modifying those values. The personal data is input only for the first time, and the previously input data is corrected only when the data value such as weight changes. Next, start / end key K5
After pressing, the body fat measurement is started by sandwiching the power supply electrodes E1, E1 and the detection electrodes E2, E2 provided on the upper and lower side surfaces of the mobile momentum meter 1 between the left and right index fingers and the thumb. Some time after the start of the measurement, the body fat percentage is displayed on the display unit D, and then when the power / selection key K1 is pressed, the basal metabolism is displayed.

To measure the amount of exercise, the mobile exercise meter 1 is attached to the arm or waist, and the measurement of the amount of exercise is started by pressing the start / end key K5. When the exercise amount measurement is started, the screen is switched each time the power / selection key K1 is pressed, and the average exercise intensity, the number of exercises, and the calorie consumption are displayed in order. The exercise amount measurement may be automatically started at a predetermined time every day.
