The purpose of this study was to find an efficient starting movement of men’s 100m sprint. Total of 10 Korea elite 100m sprinters participated in this study. They were divided into two groups which NG and UG. NG included current member of Korea National Team and UG included meber of second level Korea National Team. Three-dimensional motion analysis was performed with 7 infrared cameras and 1 force plate in sampling frequency as 200Hz and 2000Hz, respectively. The biomechanical variables such as the stride length, the stride velocity, the take-off angle, and horizontal and vertical ground reaction forces were analyzed. After this experiment following results are found. 1) In comparison with UG, the significantly less step length and non significantly fast velocity was found for NG at the first step after take-off. 2) NG revealed significantly higher take-off angle than that of UG. 3) In the ground reaction forces, less breaking forces and greater propulsive forces were found in NG compared with those of UG.

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.
