摘要

目的：本研究旨在觀察5 repetition of maximum（RM）半蹲運動誘發活化後增能作用（post-activation potentiation，PAP），對於隨後腳踏車運動的運動耐受性與攝氧動力學的影響。方法：12名大專甲組男性，採重複量數隨機平衡次序實驗設計。受試者於測驗中，進行PAP處理（4組5RM的半蹲，組間休息3分鐘）或控制（control，CON）處理，隨後進行高或激烈強度之腳踏車運動測驗。結果：高強度運動下，PAP處理的肺部攝氧動力學之平均反應時間（mean response time，MRT）顯著低於CON處理（PAP vs. CON，71±42 vs. 107±78秒，p＜.05，效果量〔effect size，ES〕＝.577）。激烈強度下，PAP處理的衰竭時間顯著優於CON處理（PAP vs. CON，261±94 vs. 192±39秒，p＜.05，ES＝.955）。結論：4組5 RM半蹲熱身，可以加速高強度運動之攝氧動力學，以及提升激烈強度下的運動耐受性。

Purpose: The aim of the study was to investigate the effects of post-activation potentiation (PAP) induced by 5 repetition of maximum (RM) squats on subsequent cycling exercise tolerance and oxygen kinetics. Methods: Twelve well-trained college male students were voluntarily recruited in this repeated measures and randomized crossover designed study. All participants performed PAP (4 sets of 5 RM squats with 3-minute rest intervals) or control (CON) treatments before heavy or severe cycling test. Results: During the heavy cycling test, the mean response time (MRT) in PAP condition was significantly faster than that in CON (PAP vs. CON, 71 ± 42 vs. 107 ± 78 s, p ＜ .05, effect size [ES] = .577). During the severe cycling test, the time to exhaustion in PAP was significantly higher than that in CON (PAP vs. CON, 261 ± 94 vs. 192 ± 39 s, p ＜ .05, ES = .955). Conclusion: PAP induced by 4 sets of 5 RM squats might enhance pulmonary oxygen uptake kinetics during heavy-intensity exercise, and might improve exercise tolerance during severe-intensity exercise.
