本研究的目的是调查单侧胫骨截肢的优秀、亚精英和非优秀短跑运动员在100米短跑中的时空参数的差异。使用公开的互联网广播，我们分析了来自30名优秀短跑运动员、12名非优秀短跑运动员和22名非优秀短跑运动员的125、19和33项记录。对于每个短跑运动员的跑步，平均速度、步频和步长是使用步数和官方比赛时间来计算的。平均速度以优秀运动员最高(8.71±0.32m/S)，其次为亚优秀运动员(8.09±0.06m/S)和非优秀运动员(7.72±0.27m/S)。虽然三组间平均步频差异有统计学意义，但效应大小较小，三组间的相对差异为3.1%。统计分析还显示，优秀短跑运动员的平均步长最长，其次是亚精英和非精英群体。这些结果表明，三组短跑成绩的差异主要是由于平均步长而不是步频。
The aim of this study was to investigate differences of the spatiotemporal parameters in a 100-m sprint among elite, sub-elite, and non-elite sprinters with a unilateral transtibial amputation. Using publicly available Internet broadcasts, we analyzed 125, 19, and 33 records from 30 elite, 12 sub-elite, and 22 non-elite sprinters, respectively. For each sprinter’s run, the average velocity, step frequency, and step length were calculated using the number of steps in conjunction with the official race time. Average velocity was greatest in elite sprinters (8.71±0.32 m/s), followed by the sub-elite (8.09±0.06 m/s) and non-elite groups (7.72±0.27 m/s). Although there was a significant difference in average step frequency between the three groups, the effect size was small and the relative difference among the three groups was 3.1%. Statistical analysis also revealed that the average step length was longest in elite sprinters, followed by the sub-elite and non-elite groups. These results suggest that the differences in sprint performance between the three groups is mainly due to the average step length rather than step frequency.
