The aim of this study was to investigate the acute effects of 16 different combinations to cause the postactivation potentiation (PAP) in elite young soccer players. Squat exercise in 4 different intensities (40%, 60%, 80%, and 100% one-repetition maximum [1RM]) was performed and its effects were evaluated in the performance of countermovement jump (CMJ), after 4 different recovery times (1, 3, 5, and 10 min). For this purpose, 25 young soccer players, underwent five experimental sessions. At the first session the control to determine 1RM in half-squat was carried out. The following four experimental sessions were comprised of four intensity combinations with four different recovery intervals in order to perform the CMJ test later, randomly determined and with 30-min interval between each combination. The conditions were compared using an analysis of variance with repeated measurements, followed by Bonferroni test, using 5% significance level (<0.05). The different intensities investigated did not provide significant increases in CMJ height, but significant differences were noted in recovery time, where, at CMJ maximum height, 1-min interval was better than after 3 min (<0.05), 5, and 10 min (<0.001). On the average jump performances, 1-min interval resulted in better results (<0.001) compared to other intervals. The 10-min recovery resulted in poorer performances compared to the other intervals (<0.001). Our results indicate that regardless the intensity used in the half-squat exercise with elite young soccer players, the 1-min recovery time was more appropriate to promote an increase in vertical jump.
本研究的目的是调查16种不同组合对精英青年足球运动员产生激活后增强效应（PAP）的急性影响。进行了4种不同强度（40%、60%、80%和100%的一次重复最大值[1RM]）的深蹲练习，并在4种不同恢复时间（1、3、5和10分钟）后，评估其对纵跳（CMJ）表现的影响。为此，25名青年足球运动员参加了五次实验课程。在第一次课程中，进行了确定半蹲1RM的对照测试。接下来的四次实验课程由四种强度组合和四个不同的恢复间隔组成，以便稍后进行CMJ测试，这些组合是随机确定的，且每种组合之间间隔30分钟。使用重复测量方差分析进行条件比较，随后进行Bonferroni检验，显著性水平为5%（<0.05）。所研究的不同强度并未使CMJ高度显著增加，但在恢复时间上存在显著差异，在CMJ最大高度时，1分钟的间隔优于3分钟（<0.05）、5分钟和10分钟（<0.001）。在平均跳跃表现方面，与其他间隔相比，1分钟的间隔产生了更好 的结果（<0.001）。与其他间隔相比，恢复10分钟导致的表现较差（<0.001）。我们的结果表明，对于精英青年足球运动员的半蹲练习，无论使用何种强度，1分钟的恢复时间更适合促进垂直跳跃的增加。
