Cycle of Double-Leg Circle on a Pommel Horse and Its Kinematics

Abstract

We investigate the eight subjects of the double-leg circle on the pommel horse, and perform the kinematic analysis of the whole body. There was a strong positive correlation between the cycle of double-leg circle and the height / weight of the subject. We clarify the transition from the time series data about the controlling of the upper trunk and lower body. We analyze the motion of the skilled subjects and discuss their characteristics. Based on the analysis results, it was suggested that the flank out motion of the legs on the pommel are important for realizing fast circle motion.
