滑行速度是滑行速度和步频的乘积。运动员只有在适当的长度和频率比下才能达到最大速度，任何长度或频率上的显著差异都会导致速度的降低。对25名（男15名，女10名）高水平短跑运动员进行了研究。每一个都被重复地在60和100米之间的距离上跑了许多次，在跑之间有适当的休息时间。在每次运行中改变硅烷长度，并将数据绘制在图中。在理论上，两个尖齿的交点用来表示lhc运动员应该走的距离和步数。他能够实现。给出了提高性能的有效训练方法的实例。
^ V Rttnning speed is the producl of siride lenglh and stride fretpiency. Athleles achieve their maximum speed only by adtipiing ti specific ratio between lenglh and freiptency of siride anil any significant alieralion in the length or the frequency will cause u reduclion in speed. .A study was inaiie of 25 (15 male and 10 female) high level spriniers. Each one was reiptiretl to run a number of times over disiances vatying between 60 and 100m, wiih adetpiaie resl periods between the runs. Siride length was changed al each run anil dala were plotted in a graph. A point at which two tines meet was used to indicate the lime and the number of strides that lhc athlele should, in iheory. he able to achieve. .Samples of effeclive training methods to improve performance are given.
