An object of the present invention is to provide a body composition measuring device used in arithmetically deriving an index indicative of body composition in accordance with the bioelectric impedance measuring method, in which a highly accurate calculation result can be obtained with the reduced effect from the fluctuation in a day while using a simple measuring method. Provided is a body composition measuring device in which the bioelectric impedance value is measured at each different frequency by applying the current at a plurality of different frequencies, for example, at a first frequency and a second frequency, to the living body, while concurrently correcting the measured bioelectric impedance value at the first frequency or at the second frequency by using the difference in the bioelectric impedance values between the first and the second frequencies to calculate the index indicative of the body composition based on the corrected bioelectric impedance value, or while concurrently calculating the index indicative of the body composition based on either one of the measured bioelectric impedance values at the first frequency or at the second frequency and then correcting the calculated index indicative of the body composition by using the difference between the bioelectric impedance values at the first and the second frequencies.

In a display section, a measured value of information of a living body is displayed on a measured data display section, and a figure representing a human body including body parts such as arm and leg is displayed on a body display section. For example, a percentage of muscle and a percentage of body fat measured 30 days ago and a current percentage of muscle and percentage of body fat are compared with each other, and respective increase / decrease values are displayed on the measured data display section as well as the measured values. Further, a color of illumination in the background of the body display section is changed depending on a degree of the increase / decrease value. For example, the background of the body display section is illuminated in red when the percentage of muscle is decreased by a % or more, blue when increased by a % or more, and green when a percentage of variation is less than a % in comparing current data with data measured 30 days ago.

A body composition measuring instrument includes a body composition calculating unit for calculating the body composition of a user by using a plurality of electrodes, a reference value storage region for storing information of a reference value related to the past body composition of the user, a display control unit for performing a control to display a position of the body composition during the time calculated by the body composition calculating unit in reference to a line showing the reference value on a predetermined graph, and a display section for providing a display corresponding to the output from the display control unit.

The invention provides a body composition measuring device (100A) having electrodes (131, 133) for a right hand, made to be in contact with the right hand of a subject, and also has electrodes (132, 134) for a left hand, made to be in contact with the left hand of the subject so to measure the body impedance of the subject. The device body has a rod-like grip portion (111) provided with the electrodes (131, 133) for a right hand, a rod-like grip portion (112) provided with the electrodes (132, 134) for a left hand, and a base portion (103) to which the grip portion (111) for a right hand and the grip portion (112) for a left hand are fixed. The grip portion (111) for a right hand is rotatablely fixed to the base portion (103), and the extending direction of the grip portion (111) for a right hand is differentiated from the extending direction of the rotating shaft thereof. Consequently, a small and thin portable body composition measuring device can be achieved.

There are provided a hold portion that can be held in a hand of a subject, a cable having one end connected to the hold portion, and a rest portion on which a foot of the subject can be rested. The rest portion includes a reel portion connected to the other end of the cable for winding the cable, a first detection unit for detecting a draw-out extent to which the cable is drawn out from the reel portion, and a second detection unit for detecting an angle formed by the rest portion and the cable. Based on the detected draw-out extent and angle, the part length of a body part of the subject is calculated.

A body composition measuring apparatus includes a right hand grip having electrodes to be contacted with the right hand of a subject, and a left hand grip having electrodes to be contacted with the left hand of the subject. The right hand grip and the left hand grip are disposed such that their respective axis lines overlap with each other on the same straight line. The left hand grip is coupled to the right hand grip in a freely movable manner such that the left hand grip can move in the axis line direction. This configuration allows a small-sized body composition measuring apparatus suitable for carrying along to be achieved.

A body composition measuring apparatus for calculating one or multiple types of body composition data is provided with a CPU configured to perform the following processes. The CPU sets second information indicating physical characteristics of a human subject. The CPU measures the bioelectrical impedance of the human subject by a voltage measurement circuit. The CPU obtains at least one piece of first information from each of at least one recording medium having recorded thereon the at least one piece of the first information necessary for calculating body composition data indicating a particular type of body composition, and calculates body composition data indicating a type of body composition corresponding to each of the at least one piece of the first information based on the at least one piece of the first information obtained by the information obtainer, the second information, and the bioelectrical impedance.

A CPU (134) of a body composition measuring apparatus (100) drives a navel position indicator (118) so that it emits light. The height of a frame (114) is adjusted so that a beam of light from navel position indicator (118) irradiates the navel of a human subject. Plural sensors (106) are mounted on the frame (114), and each sensor measures a distance from the sensor to a position to be measured, whereby the abdominal width (X) of the human subject is determined. Subsequently, CPU (134) obtains measured values of weight (W) and bioelectrical impedance (Z). CPU (134) then reads an equation for calculating the visceral fat area and estimates the visceral fat area (Y) based on the measured abdominal width (X), weight (W), bioelectrical impedance (Z), and the equation.
