The purpose of this study is to know the kinematical factors happening in 100m running phase. Represenfative 10 high school runners in Seoul are studied, using the maxmum speed phase and final phase. In addition, 3 factors such as time, speed, distanced, are analysed by comparison. 1. The average speed in maximum speed phase is 9.70m/s and the average speed in final phase is 8.37m/s, which is the 9.96% decrease of the speed. 2. The average support time in maximum speed phase is 0.11(s) and in final phase 0.13(s). This shows that the more the speed decreases the more the support time increases. This is an important factor in downing the record of 100m running. 3. When the speed comes down in 9.96% of the average speed from the maxmum speed phase to final phase, the stride frequency decreases by 7.8%. 4. Height has a very close relation with leg length, having 0.88 correlation of coefficient. Stride frequency has a anticorrelation coefficient. 5. There is little difference between the stride lenghts in the maxmum speed phase and finnal phase. 6. There is no significant differences between the flight time and the average speed.
