与健全的短跑运动员类似，历届残奥会和IPC田径世界锦标赛的100米短跑奖牌大多由西非（WA）和高加索（CC）截肢短跑运动员主导，而不是亚洲（AS）短跑运动员。尽管这些结果表明短跑表现因种族而存在差异，但对于截肢短跑运动员的 100 米短跑的种族和时空参数知之甚少。本研究的目的是调查双侧和单侧胫骨截肢的 WA、CC 和 AS 短跑运动员在 100 米短跑期间的时空参数差异。我们从公开的互联网广播中分析了 6 名 WA、28 名 CC 和 10 名 AS 截肢短跑运动员。对于每位短跑运动员的跑步，平均速度、平均步长和步频是通过步数与官方比赛时间相结合来计算的。 WA 组和 CC 组的 100 米冲刺时空参数没有发现显着差异。另一方面，AS组由于100米冲刺的步长较短，平均速度明显较低。结果表明，WA 和 CC 短跑运动员在 100 米短跑中表现相似，但 AS 短跑运动员则不然。本文的在线版本 (doi:10.1186/s40064-016-1983-1) 包含补充材料，可供授权用户使用。
Similar to able-bodied sprinters, most of the medals for the 100-m sprint in past Paralympic Games and IPC Athletics World Championships were dominated by West African (WA) and Caucasian (CC) amputee sprinters, not Asian (AS) sprinters. Although these results indicate differences in sprint performance due to ethnicity, little is known about the ethnicity and spatiotemporal parameters of the 100-m sprint for amputee sprinters. The purpose of this study was to investigate the differences in the spatiotemporal parameters of WA, CC and AS sprinters with bilateral and unilateral transtibial amputations during a 100-m sprint. We analyzed 6 WA, 28 CC, and 10 AS amputee sprinters from publicly available Internet broadcasts. For each sprinter’s run, the average speed, average step length, and step frequency were calculated by using the number of steps in conjunction with the official race time. No significant differences were found in the spatiotemporal parameters of the 100-m sprint for the WA and CC groups. On the other hand, the average speed of the AS group was significantly lower because of its shorter step length during the 100-m sprint. The results suggest that WA and CC sprinters would perform similarly during a 100-m sprint, but AS sprinters would not.
