마루운동 손짚고 앞돌아 몸펴 앞공중 1회 비틀기동작 시 상지의 운동학적 분석

초록

The purposes of this study were to analyze event and phase of handspring salto forward stretched with turn to investigate the difference of biomechanical variables between two groups as movements skill. All subjects were divided into 3 national gymnasts( skilled group) and 3 college gymnasts ( less skilled group). For this purpose, during each trial 4 high-speed video camera were used to measure movements by Kwon 3D program applied for calculation of 3-D coordinate and body joint central point. The conclusions of this study were as follows.　In terms of angular velocity, the elbow joint in the left had the lower limbs accelerate the speed to take lift. The rapid velocity of elbow joints rotated handspring rapidly and helped body be right at the takeoff. The angular velocity of elbow joints was influenced more than that of shoulder joints at twisting. And the angular velocity of trunk with body upward sufficiently made contribution to the balance for twist. The powerful movement of arms made body be high off the ground and be twisted safely.
