볼링 스윙동작시 신체중심과 볼 이동궤도의 편차에 관한 연구

Abstract

The purpose of this study was to compare between success and failure in bowling throw motions. For the data analysis, it was utilized by the method of three dimensional motion analysis and obtained kinematical parameters of stride, COG position, ball position and relative position of ball toward the C.O.G through the address and release motion. The subjects of this study were three female bowling players, and obtained conclusions were as follows; Displacements of stride were not significance of success events, 4th and 5th phase stride were longer than failure. COG variation for height were less than failure, but there were not significance between success and failure. The ball position of 3 th phase was lowest than other phases, and throw motions were stable by the small variations for upward and downward. Success events of Relative positions of ball were more regulated than failure in whole swing phases.
