휠체어 농구 자유투 동작 시 상체분절의 운동학적 요인 분석

Abstract

The purpose of this study was to analysis the kinematical variables of one-hand free throw in wheelchair basketball. The subjects of this study were four male wheelchair players registrated in wheelchair basketball athletes. Free throw motions were taken by three video cameras. Three-dimensional coordinates was processed by DLT. The variables were the time duration, displacement, velocity, angle, angular velocity during performing the free throw motion. The result of analysis is summarized as follow.In performing the free throw motion. the time duration of backward motion showed longer than its of forward motion, and most subjects used forearm for extending the elbow joint than hand and upperarm segment. Therefore for improving free throw motion skill in wheelchair basketball players it should be trained the increase of wrist snap motion.
