Abstract: At least two electrodes are disposed at a predetermined interval on a living body surface, a first voltage V1 generated when a first external resistor is connected in parallel between the two electrodes, and a second voltage V2 generated when a second external resistor is connected in parallel between the two electrode are measured, a bioimpedance between the two electrodes at a muscle site under the living body surface is calculated based on a voltage ratio V1/V2 between the first voltage V1 and the second voltage V2, and local muscle fatigue at the muscle site is evaluated based on a change over time in the calculated bioimpedance.
