| 摘 要： | 论文对20年来男子短跑成绩演变和1997年田径世锦赛男子400 m成绩数据(400 m各个阶段的跑速、步长、步频、步数)进行了深入的分析,认为:世界男子400 m短跑成绩近20年稳步提高,且围绕奥运会周期呈现波动规律;世界男子400 m短跑运动员平均最高速度的产生段落在50～150 m之间,速度明显下降发生在300 m处;在300～350 m所有选手步长降至最低,冲刺阶段略有回升,大部分运动员步频在50～100 m段落增大至最高水平,然后逐渐下降;步频和步长高度的负相关,年龄与步长高度正相关,最高速度和速度耐力在很大程度上决定着400 m成绩.

| Abstract: | The data of the performance for men's 400-meter running in 1997 world championship are deeply analyzed in this paper. The following conclusions are drawn: the performance of 400 meters running for man has been increased steadily but have been up and down regularly in the Olympiad; generally, the fastest speed appears from 50 meters to 150 meters, the decrease of speed appears at 300 meter; the stride length gets to the shortest from 300 meters to 350 meters, and then longer a little during the sprint phase; for most of the athletes, stride frequency gets to the top level from 50 meters to 100 meters and then decrease step by step. Correlativity between stride frequency and stride length is negative, but correlativity between age and stride length is positive, top speed and stamina are determinant for 400meter. |
