At this time, the pressure sensor 142 obtains data and transmits it to the display 201, and the dominant leg is measured during measurement. After that, the subjects are evaluated based on their age, gender, weight, height, etc., and their own data are compared to determine the muscle condition of the subjects and predict the risk of sarcopenia.
