| Abstract: | In this paper, the authors make a comprehensive analysis on some kinematic data, which include the projectile veloctity, projectile angle and so on collected from 21 elite long jumpers both in and out of China, and the optimum projectile angle and the effect of projectile angle on jump distance are explored by the mathematic means. Therefore, the authors point out that an increase in projectile angle is an efficient technical measure to raise fundamentally utilization ratio of approach velocity and increase jump distance. |
