The purpose of this study was to investigate the postactivation potentiation effect after a heavy resistance stimulus (HRS) on running speed (RS). Fifteen amateur team game players (basketball, volleyball, handball, and soccer players), ages 18-23 years running the 30-m dash and the intermediate phase of 0-10 and 0-30 m sprints, were used to evaluate RS. Resistance training consisted of 10 single repetitions at 90% of 1 repetition maximum. The running tests were performed 3 times--(a) 3 minutes prior the HRS, (b) 3 minutes after the HRS, and (c) 5 minutes after the HRS--in separated training sessions. Results showed that RS was not affected 3 minutes after the resistance training, but it increased for both selected running phases (0-10 and 0-30 m) 5 minutes after the HRS (p < 0.05). These findings indicate that heavy resistance exercise improves 10- and 30-m sprint performance when performed 5 minutes after the exercise bout.
本研究的目的是调查重负荷阻力刺激（HRS）后对跑步速度（RS）的激活后增强效应。选取了15名年龄在18 - 23岁的业余团队项目运动员（篮球、排球、手球和足球运动员），通过30米短跑以及0至10米和0至30米短跑的中间阶段来评估跑步速度。阻力训练包括以1次最大重复量的90%进行10次单组重复。跑步测试分三次进行——（a）在重负荷阻力刺激前3分钟，（b）在重负荷阻力刺激后3分钟，以及（c）在重负荷阻力刺激后5分钟——在不同的训练时段。结果显示，阻力训练后3分钟跑步速度未受影响，但在重负荷阻力刺激后5分钟，选定的两个跑步阶段（0至10米和0至30米）的跑步速度均有所提高（p < 0.05）。这些发现表明，在运动 bout 后5分钟进行重负荷阻力训练可提高10米和30米短跑成绩。
