It is unclear if a constant sprint-to-rest ratio allows full performance recovery between repeated sprints over different distances. This is important for the development of sprint-training programs. Additionally, there is conflicting evidence on whether active recovery enhances sprint performance. Three repeated sprint protocols were used (22 × 15, 13 × 30, and 8 × 50 m), with each having an active and passive recovery. Each trial was conducted with an initial sprint-to-rest ratio of 1:10. Repeated sprints were analyzed by comparing the first sprint to the last sprint. For the 15-m trials, there were no significant main effects for recovery or time and no significant interaction. For the 30-m trials, there was no main effect for recovery, but a main effect for time (F[1,10] = 15.995, p = 0.003; mean difference = 0.20 seconds, 95% confidence interval [CI] = 0.09-0.31 seconds, d = 1.4 [large effect]). There was no interaction of recovery and time in the 30-m trials. For the 50-m trials, there was no main effect for recovery, but a main effect for time (F[1,10] = 34.225, p = 0.0002; mean difference = 0.39 seconds, 95% CI = 0.24-0.55 seconds, d = 1.3 [large effect]). There was no interaction of recovery and time in the 50-m trials. The results demonstrate that a 1:10 sprint-to-rest ratio allows full performance recovery between 15-m sprints, but not between sprints of 30 or 50 m, and that recovery mode did not influence repeated sprint performance.
目前尚不清楚在不同距离的重复冲刺中，恒定的冲刺-休息比例是否允许充分的性能恢复。这对于短跑训练计划的制定很重要。此外，关于主动恢复是否能提高短跑成绩，也存在相互矛盾的证据。使用了三种重复冲刺协议（22×15、13×30 和 8×50 m），每个协议都有主动和被动恢复。每个试验都以初始冲刺-休息比例为 1:10 进行。通过比较第一次冲刺和最后一次冲刺来分析重复冲刺。对于 15 m 的试验，恢复或时间都没有显著的主效应，也没有显著的交互作用。对于 30 m 的试验，恢复没有主效应，但时间有主效应（F[1,10] = 15.995，p = 0.003；平均差异 = 0.20 秒，95%置信区间 [CI] = 0.09-0.31 秒，d = 1.4 [大效应]）。30 m 的试验中，恢复和时间之间没有交互作用。对于 50 m 的试验，恢复没有主效应，但时间有主效应（F[1,10] = 34.225，p = 0.0002；平均差异 = 0.39 秒，95%CI = 0.24-0.55 秒，d = 1.3 [大效应]）。50 m 的试验中，恢复和时间之间没有交互作用。结果表明，1:10 的冲刺-休息比例允许在 15 m 的冲刺之间完全恢复性能，但在 30 m 或 50 m 的冲刺之间则不行，而且恢复方式并不影响重复冲刺的性能。
