| Abstract: | A study of the effect of the impulse, generated during the support-time of asingle step on the speed, stride length and stride frequency is presented. This isdone through a mathematical analysis of the technical index data of the runnersat different trainning levels. The running speed depends not only on the amountof the force, but also on the time duration that the force lasts. Therefore, toimprove the speed, a player must decrease support-time, especially leg drive-time.The key is to increase leg driving power. |
