我国运动员在比赛的过程中因为踏跳的失误而影响比赛成绩的情况比较普遍。这种现象严重的制约了我国跳远的发展与运动员的成绩。应该如何正确地通过调整助跑以及后阶段的步长来保证踏跳的准确性呢?以及后阶段的助跑步长对踏跳的准确性有何影响。本文通过研究国内外优秀运动员的相关数据得出后四步的步长对踏跳准确性的影响最大,并且步长间的波动愈小,踏跳的准确性越高。
It is quite common for athletes in our country to influence the performance of the competition due to errors in jumping during the competition. This phenomenon severely restricts the development of long jump and the performance of athletes in our country. How to correctly ensure the accuracy of the jump by adjusting the run-up and the step of the next step? And how does the run-length of the next step affect the accuracy of the jump? In this paper, by studying the relevant data of elite athletes at home and abroad, it is concluded that the last four steps have the greatest impact on the accuracy of jump, and the smaller the fluctuations between steps, the higher the accuracy of jumping.
