A squat is an exercise in which the knee is repeatedly flexed and extended from an upright position. It has been reported that a decrease in the velocity of the center of gravity of the body is one of the causes of falls during standing up motion in the elderly. Clarifying the contribution of each muscle to exercise speed during squatting requires quantification of the relationship between exercise speed and lower limb muscle forces, which is useful for evaluating motor function. Therefore, in this study, we construct a squat model that estimates the velocity of the center of gravity using lower limb muscle forces that contribute to hip and knee flexion and extension, and ankle dorsiflexion and plantarflexion. Furthermore, by applying the proposed method to squats with different stance widths, we verify the contribution of each muscle to the motion velocity.
