Comparison of the Manners of Body Uses for Double-Leg Circles on Pommel Horse: Waist and Chest

Abstract

We have investigated one of the fundamental maneuvers on Pommel Horse gymnastics, “Double-Leg Circles.” On our studies, an optical motion-capture system and some devices obtain the motion information of human-wholebody. Based on this information, the inverse-dynamics simulations of the wholebody-musculoskeletal model and the analysis of this simulation can be obtained. In this paper, we showed the correlation between the score of the player’s motion skills from the coaches and the terms about the times of one circle, the joint angle trajectories of 5^th lumber vertebra and 12^th rib vertebra and the ration of double hand support time to one circle time. Also, we evaluated the synchronization level of moving waist and chest by correlation analysis and compared the motion skills of multi-players with the scores from the coaches and correlation analysis.
