PROBLEM TO BE SOLVED: To obtain information on muscle fatigue grade or the like of a human body by easy measurement through a noninvasive measurement device. SOLUTION: The muscle fatigue grade measurement device has a weight measurement means for measuring body weight, a vibration means for imparting vibration to a part of a body, a detection means for detecting the vibration transmitted through the body at the other parts of the body, and an analysis means for analyzing and informing characteristics of muscle of the body from detected vibration and measured body weight. The vibration is imparted to the heel of one foot of the body and is detected at the heel of the other foot. The analysis means comprises a first operation part for carrying out Fourier analysis of a vibration signal detected by the detection means, and a second operation part for analyzing hardness of the muscle from the result of the operation and weight signal measured by the weight measurement means. The relation of the result of Fourier analysis, the weight signal and the hardness of the muscle is determined by regression analysis, and the relation is referred to from the result of Fourier analysis through the measured vibration and the weight signal and the hardness of the muscle is obtained in the second operation part.
