초록

The purpose of this study was to evaluate the success factors of the Double Salto Backward Piked Dismount in the parallel bar in gymnastics. For this study, 3 national male-gymnasts participated in this experiment. The two digital video cameras(Sony, PD-150) were used to record motions. Kwon3D 2.1 was used to process data and analyze for factors. The results were as follows: First, at down swing, a rapid vertical, horizontal velocity and angular velocity of hip joint made swing and vertical motion large, and then they were helpful to acquire a rotation effect and airborne height efficiently. At release, whip-swing was strong and rapid because at maximum hip extension small scapular angle cause them to swing down near body, that is, hip joint sustained large extension. Second, because a large scapular angle and a rapid angular velocity of hip joint by means of rapid vertical velocity made position high and whip-swing strong at release, they made the salto high and rotation efficient. Third, long spent time and a high vertical height of hip joint made room to rotate the Double Salto Backward Piked Dismount during airborne phase. A small angle of hip joint and a rapid vertical velocity made stable landing efficiently. In conclusion, success factors of the Double Salto Backward Piked Dismount were a small horizontal displacement, a high vertical displacement, the rapid velocity of rotation and the high vertical position during landing. Therefore, they produced stable airborne and landing motions.
