For athletes using running-specific prostheses (RSPs), current Paralympic guidelines for track events are generally based on level of amputation, not side of amputation. Although 200- and 400-m sprint races are performed in a counterclockwise direction, little is known about the effects of amputation side on race performance in athletes with unilateral lower limb amputation. The study aim was to test whether athletes using RSPs on their left side have slower race times than those using RSPs on their right side.
Athletes with unilateral lower limb amputation (N = 59 in total) participating in elite-level 200-m races were analyzed from publicly available Internet broadcasts. These races included the 2008 Beijing and 2012 London Paralympics, and the International Paralympic Committee Athletics World Championships in 2011 and 2013. For each athlete the official race time and amputation side were determined. There was no significant difference in number of participants and race time between left and right side amputees in T42 men, T44 men, and T44 women.
The results of the present study suggest that sprint performance of athletes using RSPs is not affected by amputation side on a standard 400-m track.
对于使用特定跑步假肢（RSPs）的运动员，目前残奥会田径项目的指导方针通常基于截肢水平，而非截肢侧。尽管200米和400米短跑比赛是沿逆时针方向进行的，但对于单侧下肢截肢运动员而言，截肢侧对比赛成绩的影响却知之甚少。本研究的目的是测试使用左侧RSPs的运动员比赛用时是否比使用右侧RSPs的运动员更长。
通过公开的网络直播，对参加精英级200米比赛的单侧下肢截肢运动员（共59名）进行了分析。这些比赛包括2008年北京残奥会、2012年伦敦残奥会以及2011年和2013年国际残奥委会田径世界锦标赛。确定了每位运动员的官方比赛用时和截肢侧。在T42男子组、T44男子组和T44女子组中，左侧和右侧截肢运动员的参赛人数和比赛用时没有显著差异。
本研究结果表明，在标准400米跑道上，使用RSPs的运动员的短跑成绩不受截肢侧的影响。
