The purpose of this study was to compare kinematic factors between two groups (a skilled vs. an unskilled group) for Yamawaki in horizontal bar. Eight national man gymnasts participated in this study, and eight Oqus-300(200Hz), infrared cameras were used to capture motions for three dimensional analysis. The results were as follows: First, skilled men made a swing with them upward and horizontal at release, but unskilled men with them vertical near horizontal bar. Second, skilled men had a low vertical position at release but a high during aero flight and a high vertical position at landing. On the contrary, unskilled men had a high vertical position at release but a low during aero flight and a low vertical position at landing. Unskilled men's low horizontal velocity during upward swing made a high vertical position at release. Third, after skilled men threw themselves backward by means of a rapid horizontal velocity at release, they erected their upper bodies inversely with them pulling the horizontal bar. But it was difficult that unskilled men erected their upper bodies by means of throwing themselves upward from rapid vertical velocities at release. Fourth, skilled men made large shoulder joint angles, but unskilled men made large hip joint angles at landing. Also, at landing, unskilled men’s small shoulder joint angles and large hip joint angles made a landing near the horizontal bar and a performance by means of hip joint flexing excessively.

현대사회에 있어서 신체활동 연구의 주요 탐구과제는 ‘신체활동을 통한 교육’으로부터 ‘인간의 기본적인 움직임’을 목표로 하는 스포츠적인 움직임을 중심으로 한 생명 활동의 개념으로 급속히 변화되고 있는 추세이다. 이러한 환경변화에 대응하기 위하여 본학회는 ‘체육’적인 요소에서 ‘스포츠’적인 요소를 중심으로 한 학문적 정체성을 견고히 하고, 정기적인 학술지 발간과 학술활동을 통해 한국스포츠츠 문화의 발전과 학문적인 발전에 기여하는데 그 목적이 있다.
