Various methods such as an underwater weight method, a heavy water dilution method, and a caliper (skin thickness gauge) method are provided. The underwater weight method is to obtain the body density from the weight when diving underwater in the state of maximum exhalation and the weight in the air, and to estimate the body fat percentage by the so-called Archimedes principle. This is "body fat percentage (%) =
(4.570 / body density-4.142) × 100 ”, which is the most commonly used method for accurately determining the body fat percentage.

正確に求める手法として一般的に用いられている。The heavy water dilution method is a method of obtaining the body fat content and the body fat percentage by utilizing the fact that the proportion of the body water content in the lean body mass is almost constant. This heavy water dilution method uses heavy water (D 2 O) as a tracer and weighs 1 kg.
Per 1 g of heavy water diluted to 20% or less with drinking water is orally administered, and the body water content is estimated from the heavy water concentration in urine several hours after the administration. The body fat percentage is calculated by using the percentage (%) of water content in the body weight as “body fat percentage (%) = 1
00-water content (%) / 0.732 ". This heavy water dilution method is also commonly used as a method for accurately obtaining the body fat percentage, similar to the underwater weight method.

For this reason, the subject a is going to be placed in a resting state such as a supine position or a sitting position to eliminate the influence of the measurement. For this reason, the conventional body fat mass measuring device A
Requires that the input unit 3 for the physical data such as height, weight, age, and sex required for calculation and the display unit 4 for the measured value be placed in a position that is difficult for the subject to handle. In addition to b, a measurer was needed. However, anthropometric measurements such as body fat mass and weight belong to the privacy of individuals and are values that one does not want to be known by some people. It is a psychological burden. Further, in the conventional measurement method, the presence of a measurer is a prerequisite, so it is difficult to easily measure the body fat percentage, which hinders the use of the body fat amount for daily health management. .

すれば人体のインピーダンスを正確に測定できる。The electrodes for impedance measurement are composed of four electrodes, one set for current application and the other for voltage measurement, and the electrodes for current application and voltage measurement are spaced from each other by about 3 cm or more. ing. The impedance measurement of the human body in the present invention is performed using the so-called four-electrode method.
This four-electrode method uses four electrodes, and a constant current application electrode and a voltage detection electrode are used as one set to measure impedance, and the impedance is measured at both ends of a human body measurement site. The current applying electrode is placed outside and the voltage detecting electrode is placed inside, and then a high frequency of about 50 KHz is applied to the constant current applying electrode.
An impedance value is obtained by applying a constant current of about 00 μA and detecting the potential difference from the voltage detection electrode. Based on the measured impedance value and the height, weight, age and sex as the body data input by the input unit 3, the body fat percentage is estimated by the calculation unit 8 and displayed on the display unit 4. Here, if the input impedance of the amplifier when measuring the potential difference is made sufficiently large, the impedance of the human body can be accurately measured.

式から推定する。The estimation of the body fat mass from the impedance value is based on the following principle. Since the impedance is proportional to the length of the conductor and inversely proportional to the cross-sectional area of the conductor, it can be expressed by equation (1). Z = ρL / a …………………………………… (1) where Z is impedance (Ω) ρ is conductivity (Ωcm) L is conductor length (cm) a is cross-sectional area (cm) 2 ) From equation (1), Z = ρL 2 / aL = ρL 2 / V ……………… (2) V is the conductor capacitance From equation (2), V = ρL 2 / Z ………………………… (3) From equation (3), the biocapacity V is proportional to the square of the length of the conductor,
It will be inversely proportional to the impedance. Therefore,
The biocapacity can be estimated by knowing the conductor length and impedance. Impedance is the sum of the resistance and reactance vectors. However, the reactance in the living tissue is very small compared to the resistance value, and the correlation with the impedance is also low, so that the impedance can be replaced with the resistance. Therefore, the body water content or the body fat content as the body composition is estimated from the relational expression that it is proportional to the square of the height which is the length of the conductor and is inversely proportional to the bioelectrical resistance value (resistance), that is, the impedance.
