ABSTRACT:
A method and apparatus for determining body composition of a subject is provided. The composition determinations can include total body fat, lean body mass, total body water, inter-cellular fluid and/or extra-cellular fluid. The subject's body is treated as a plurality of segmented conductors, each of the body segments having a relatively uniform cross-sectional area. By determining the composition of one or more exemplary body segments, the total body composition can be determined. The method in accordance with the present invention selects one or more body segments and introduces a uniform current flow through the body segments. The impedance which each of the body segments presents to the current flow is measured by a pair of voltage sensing electrodes positioned at each end of the body segments. Preferred body segments include the subject's thigh, trunk, and upper arm. The length of the body segment and its cross sectional area are used, as well as the gender of the subject, in combination with the bioelectrical impedance of the body segment to determine the body composition.
