The present study aimed to investigate the effects of post-activation performance enhancement (PAPE) after three warm-up protocols on back squat performance in trained men.
Fourteen resistance-trained men performed conditioning activity (CA) with high-load (HL-CA), low-load (LL-CA), or usual specific warm-up as a control (CON). HL-CA consisted of one set of three repetitions with 90% of one repetition maximum (RM); LL-CA consisted of one set of six repetitions with 45% of 1 RM performed at maximal velocity; CON involved eight repetitions with 45% of 1 RM at controlled velocity. The participant's performance was measured using the total number of repetitions and volume load (reps × load × sets).
There were no significant differences between warm-up for the total number of repetitions ( = 0.17) or total volume load ( = 0.15). There was no difference between conditions for the number of repetitions (main condition effect; = 0.17); however, participants achieved a significantly higher volume load after HL-PAPE than after CON for the first set ( = 0.04).
High or low equated-load CA used as warm-up strategies did not potentiate subsequent performance enhancement in multiple-set back squat exercise performed until muscle failure in comparison with usual warm-up.
本研究旨在探讨三种热身方案后的后激活性能增强（PAPE）对有训练的男性深蹲表现的影响。
14 名有抗阻训练经验的男性进行了条件活动（CA），包括高负荷（HL-CA）、低负荷（LL-CA）或通常的特定热身作为对照（CON）。HL-CA 由一组三个重复，使用 90%的一次重复最大重量（RM）组成；LL-CA 由一组六个重复，使用 45%的 1 RM 以最大速度进行；CON 涉及 8 次重复，使用 45%的 1 RM 以受控速度进行。参与者的表现通过总重复次数和总负荷量（重复次数×负荷×组数）来衡量。
在总重复次数（ = 0.17）或总负荷量（ = 0.15）方面，热身之间没有显著差异。在重复次数方面，条件之间没有差异（主要条件效应； = 0.17）；然而，与 CON 相比，HL-PAPE 后，参与者在第一组中实现了显著更高的负荷量（ = 0.04）。
与通常的热身相比，高负荷或低负荷的等负荷 CA 作为热身策略，在多组深蹲练习中，直到肌肉疲劳，并没有增强随后的性能增强。
