Abstract

A muscular volume balance measuring apparatus that measures the balance of the muscular volume in a specific part is provided. At least two sets of current applying, devices for inserting a specific part of the body and applying current to living bodies, or a voltmeter, which measures voltage, are provided. A bioelectricity impedance measuring device which measures bioelectricity impedance of a measured region from applied current and measured voltage is also provided. A muscular volume calculating device which computes muscular volume from measured bioelectricity impedance is also provided. Further, balance of muscular volume of the inserted part is calculated from each set of the computed muscular volume. In addition, there is a feature of being able to expand and contract for the longitudinal width, which is the distance which inserts a specific part, and breadth, which is the distance between current applying device or between the voltmeter.
