Abstract: A biometric measurement system capable of measuring an immediate response of a living body to the intervention of a physical stimulus to the living body is provided. A biometric measurement system (210) capable of applying electrical muscle stimulation to a living body comprises: an electrode for bioelectrical impedance measurement (217a-217d) for measuring a bioelectrical impedance of a living body; and an electrode for electrical muscle stimulation (217e, 217f) for applying electrical muscle stimulation to the living body, wherein the electrode for bioelectrical impedance measurement (217a-217d) and the electrode for electrical muscle stimulation (217e, 217f) are arranged to contact the living body simultaneously.

Abstract: A muscle condition change determination apparatus includes a circuit. The circuit configures: a change information acquisition unit; and a type determination unit. The change information acquisition unit acquires change information indicating changes in a plurality of muscle indicators. The type determination unit determines the type of change in a muscle condition according to the change information.

Abstract: A body composition meter has a multi-frequency current application unit to apply an AC current of multiple frequencies to a body of a subject, an impedance measurement unit to measure bioelectrical impedances of the subject when the AC current is applied by the multi-frequency current application unit at the respective frequencies, a body composition measurement unit to obtain parameters on a body composition of the subject based on the bioelectrical impedances measured by the impedance measurement unit, a measured data Cole circle calculation unit to calculate a Cole circle of measured data using resistances and reactances in the bioelectrical impedances at the respective frequencies as measured by the impedance measurement unit, and a measurement anomaly determination unit to determine the presence or absence of an anomaly in the measurement of the bioelectrical impedance based on an amount of shift of the Cole circle (C1) of the measured data calculated by the measured data Cole circle measurement unit rel
