Abstract

A theoretical analysis of the long jump take-off is presented, with the conclusion that elastic effects are important. Measured data from the literature for groups of top athletes and average performers in the long jump confirm this conclusion and lead to an estimate of elastic energy conversion efficiency, which is very low (between 0.2 and 0.3), in contrast with much higher conversion efficiencies for the running stride.

摘要

本文对跳远起跳进行了理论分析，得出弹性效应很重要的结论。从文献中获取的顶级运动员和普通跳远运动员群体的测量数据证实了这一结论，并得出了弹性能量转换效率的估计值，该值非常低（在0.2到0.3之间），这与跑步跨步时高得多的转换效率形成对比。
