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.
