摘　　要：论文对 2 0年来男子短跑成绩演变和 1 997年田径世锦赛男子百米成绩数据 (1 0 0m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 1 0 0m短跑成绩近 2 0年稳步提高 ;世界男子 1 0 0m短跑运动员平均最高速度的产生段落在 5 0～ 70m之间 ,速度下降发生在 90～ 1 0 0m ,下降幅度达 4 .72± 1 .2 3% ;在冲刺阶段 ,大部分运动员步幅增大至最高水平 ,步频和步长高度的负相关 ,年龄与步长高度正相关 。The evolution of world men's 100 meter dashing performance and the statistics of man's 100 meter dashing in 1997 World Athletics Championship (speed, stride length, stride frequency and stride number) are carefully analyzed. It's held that the performance of world man's 100 meter dashing has been improved steadily during the past 20 years; generally, prestissimo appears from 50 meters to 70 meters; the decrease of speed appears from 90 meters to 100 meters; the range of decrease is 4.72±1.23%; during the sprint phase, stride length gets to the highest level, and the correlativity between stride frequency and stride length is negative. But the correlativity between age and stride length is positive and top speed is determined by the 100 meter performance.
