Abstract：
UNASSIGNED: Prior work regarding post-activation performance enhancement (PAPE) has shown that various resistance training methods and conditioning activities may induce a PAPE effect such as free weight resistance, accommodating resistance or isoinertial resistance. However, the accommodating resistance and other types of resistance have rarely been directly compared. Thus, the aim of this study was to compare the effects of two different conditioning activities (CA) - a trap bar deadlift with (FW + AR condition) or without (FW condition) accommodating resistance - on subsequent squat jump (SJ) performance after a short rest interval of 90s.
UNASSIGNED: The study had a cross-over design and fifteen strength trained males (mean age: 22.9 ± 2.1 years; mean relative strength level 2.01 ± 0.27 kg/body mass) participated in one familiarization, two experimental and one control session (CNTR condition). Two CAs were implemented throughout the study - a single set of 3 repetitions of a trap bar deadlift at 80 % of 1RM using solely free weight resistance or with the addition of approximately 15 % of 1RM elastic band tension. The SJ measurements were performed at the baseline and 90s after CAs.
UNASSIGNED: The FW + AR condition significantly improved subsequent SJ performance (p < 0.05, effect size 0.34) whereas the FW and CNTR conditions were found to be ineffective to acutely enhance performance.
UNASSIGNED: Our results suggest that the addition of accommodating resistance is superior to free weight resistance in order to acutely improve jump performance after a 90s rest interval. To observe the performance enhancement effect with solely free weight resistance it should be considered to introduce alteration in loading strategies or possibly lengthening the rest interval.

摘要：
■关于激活后表现增强（PAPE）的先前工作表明，各种阻力训练方法和调节活动可能会引起PAPE效应，例如自由体重阻力，适应阻力或等惯性阻力。然而,容纳阻力和其他类型的阻力很少直接比较。因此，这项研究的目的是比较两种不同的条件活动（CA）-具有（FWAR条件）或不具有（FW条件）适应阻力的陷阱杆硬拉-对随后的下蹲跳跃（SJ）性能的影响短暂休息间隔90。
■该研究进行了交叉设计，15名经过力量训练的男性（平均年龄：22.9±2.1岁；平均相对力量水平为2.01±0.27kg/体重）参加了一次熟悉，两个实验和一个控制会话(CNTR条件)。在整个研究过程中实施了两个CA-在1RM的80％下，仅使用自由重量阻力或添加约15％的1RM弹性带张力，进行了3次重复的陷阱杆硬拉。SJ测量在基线和CA后90s进行。
■FW+AR条件显著改善了随后的SJ性能(p<0.05,效应大小为0.34),而发现FW和CNTR条件对急剧增强性能无效。
■我们的结果表明，增加调节阻力优于自由重量阻力，以便在90年代的休息间隔后急剧提高跳跃性能。为了观察仅具有自由重量阻力的性能增强效果，应考虑改变加载策略或可能延长休息间隔。
