Sarcopenia evaluation method, sarcopenia evaluation device, and non-transitory computer-readable recording medium in which sarcopenia evaluation program is recorded

A non-transitory computer-readable recording medium in which a sarcopenia evaluation program that evaluates sarcopenia based on a walking motion of a subject is recorded, wherein

• the non-transitory computer-readable recording medium causes a computer to function so as to acquire walking data related to walking of the subject,
• so as to detect, from the walking data, at least one of an angle of a knee joint of one leg in a stance phase of the one leg of the subject, an angle of the knee joint of the one leg in a swing phase of the one leg, a vertical displacement of a toe of one foot in the stance phase, a vertical displacement of the toe of the one foot in the swing phase, an angle of an ankle joint of the one foot in the stance phase, and an angle of the ankle joint of the one foot in the swing phase, and
• so as to determine whether or not the subject has sarcopenia using at least one of the angle of the knee joint in the stance phase, the angle of the knee joint in the swing phase, the vertical displacement of the toe in the stance phase, the vertical displacement of the toe in the swing phase, the angle of the ankle joint in the stance phase, and the angle of the ankle joint in the swing phase.
