体院学生100m成绩与步长步频变化规律及特点分析

步长、步频是决定跑速的两个主要因素。体院学生 10 0m跑步长、步频在短跑教学后发生了怎样的变化 ?笔者就此进行了初步研究 ,结果表明 ,通过短跑教学后 ,绝大多数学生的步长、步频得到了改善和提高 ,步长和步频两个参数产生了新的组合 ,使 10 0m跑成绩得到了提高。在步长和步频两个因素中 ,男生表现为步长提高率大于步频提高率 ,而女生则表现为步频提高率大于步长提高率。

Analysis on P.E Students' Sprint Performance and Characteristics of Changes in Stride Length and Stride Frequency

WT5”,6BZ]Stride length and stride frequency are the main factors determine running velocity, what changes do happen in P.E institute students′ stride length and stride frequency after sprint teaching? What can the changes offer to help improve sprint perform ance and sprint teaching and training? this paper make a initial research to the changes,the result of research shows: after sprint teaching, most students′ stride length and frequency are improved, a new combination of stride length and stride frequency, as for the two factors--stride length and stride frequency, male students make more improvement in stride length than stride frequency, while, female students make more improvement in stride frequency than in stride length.
