Abstract：
BACKGROUND: Various studies have used different exercise protocols as post-activation performance enhancement (PAPE) stimulus; however, little attention has been given to the effects of exercise range of motion on the PAPE effect and subsequent performance enhancement. This study aimed to compare the PAPE responses induced by the bench press performed with different ranges of motion on subsequent bench press throw performance.
METHODS: Ten resistance-trained males (age: 26 ± 3 years; body mass: 93.2 ± 9.4 kg; height: 181 ± 6 cm; experience in resistance training: 6.3 ± 2.4 years; relative bench press one-repetition maximum (1RM) 1.54 ± 0.2 kg/body mass) performed four experimental sessions consisting of a single set of the bench press at 80%1RM until mean barbell velocity dropped by 10% as the conditioning activity (CA) with a (1) standard, (2) cambered, (3) and reversed cambered barbell or a control condition in which the participants did not perform any CA. To assess the PAPE effect, single-sets of 2 repetitions of the bench press throw at 30%1RM were performed before and after the CA at the following time points: 2, 4, 6, 8, 10 min.
RESULTS: The two-way ANOVA (4 conditions × 2time points) showed a significant interaction for peak power (p < 0.001; η2 = 0.556) and peak velocity (p = 0.001; η2 = 0.457). The standard barbell bench press CA led to the greatest performance enhancement in peak power (p = 0.001; ES = 0.54) and in peak velocity (p = 0.002; ES = 0.71) within the examined conditions.
CONCLUSIONS: The results of this study indicate that the range of motion of the CA has a significant impact on the magnitude of the PAPE response, and the greatest effect can be reached when the range of motion of the CA and the subsequent explosive task is similar.

摘要：
背景：各种研究都使用不同的运动方案作为激活后表现增强（PAPE）刺激；但是，很少注意运动范围对PAPE效果和随后的性能增强的影响。这项研究旨在比较不同运动范围的卧推对后续卧推投掷性能的PAPE反应。
方法：10名受阻力训练的男性（年龄：26±3岁；体重：93.2±9.4kg；身高：181±6cm；阻力训练经验：6.3±2.4年；相对卧床一次重复最大（1RM）1.54±0.2kg/体重）进行了四次实验，其中包括一组卧床在80％1RM下，直到平均杠铃速度下降10％（CA作为标准活动（(2)拱形，（3）和反向弯曲杠铃或参与者未执行任何CA的对照条件。为了评估PAPE效应，在CA之前和之后，在以下时间点进行单组2次重复的卧推投掷30％1RM：2、4、6、8、10分钟。
结果：双向方差分析（4个条件×2个时间点）显示出峰功率（p<0.001；η2=0.556）和峰速度（p=0.001；η2=0.457）的显着相互作用。在检查条件下，标准杠铃台式压力机CA可最大程度地提高峰值功率（p=0.001；ES=0.54）和峰值速度（p=0.002；ES=0.71）的性能。
结论：这项研究的结果表明，CA的运动范围对PAPE响应的幅度有重大影响，当CA的运动范围与随后的爆炸任务相似时，可以达到最大的效果。
