An apparatus for analyzing body composition based on biolectrical impedance analysis, and a method therefor are disclosed. The method for analyzing body composition includes the step of providing eight electrodes E1-E8 for being contacted to a right palm, a right thumb, a left palm, a left thumb, a right front sole, a right rear sole, a left front sole and a left rear sole. A switch (10) is selected by a command of a micro-processor (14) so as to form a current path. A current is made to flow through said selected electrodes and through a human body to an impedance measuring instrument (11). A switch (10) is selected by a command of said micro-processor (14) so as to form voltage electrodes. Impedances for respective body segments are measured by means of the impedance measuring instrument (11) on the basis of the current and voltage of the impedance measuring instrument (11). Then the body composition is analyzed from the measured impedances.

Appareil pour l'analyse de la composition du corps à partir d'une analyse de l'impédance bioélectrique, et procédé correspondant. Ce procédé d'analyse de la composition du corps consiste à prévoir huit électrodes (E1 à E8) destinées respectivement à être mises au contact de la paume droite, du pouce droit, de la paume gauche, du pouce gauche, de la partie antérieure de la plante du pied droit, de la partie postérieure de la plante du pied droit, de la partie antérieure de la plante du pied gauche et de la partie postérieure de la plante du pied gauche. Un commutateur (10) est commandé par un microprocesseur (14) de manière à former un chemin parcouru par un courant. On fait passer un courant au travers desdites électrodes et du corps du sujet jusqu'à un instrument (11) de mesure de l'impédance. Le commutateur (10) est commandé par le microprocesseur (14) de manière à former des électrodes de tension. On mesure les impédances pour les parties respectives du corps au moyen de l'instrument (11) de mesure de l'impédance et en fonction du courant et de la tension de celui-ci. Ensuite, on analyse la composition du corps à partir des impédances mesurées.
