Nickerson, BS, Williams, TD, Snarr, RL, and Park, K-S. Individual and combined effect of inter-repetition rest and elastic bands on jumping potentiation in resistance-trained men. J Strength Cond Res 33(8): 2087-2093, 2019-The purpose of this study was to determine the individual and combined effects of cluster sets (CS) and elastic bands for jumping potentiation in resistance-trained men. Twelve resistance-trained men (age: 22 ± 3 years) participated in this study. In a random order, participants completed 1 set of 3 repetitions at 85% 1-repetition maximum for the parallel back squat: (a) traditional set with continuous repetitions; (b) continuous repetitions with elastic bands (BANDS); (c) CS with 30 seconds of rest between each repetition (CS30); and (d) CS with 30 seconds of rest between each repetition and elastic bands (CS + BANDS). Vertical jump height (JH) and peak power (PP) were measured before exercise (baseline) and at 1, 4, 7, and 10 minutes after exercise for each condition. Results revealed that PP at 10 minutes was significantly higher than 7 minutes for BANDS (p = 0.035) and that 4 and 7minutes were both significantly higher than baseline for CS + BANDS (p = 0.008 and 0.031, respectively). No other differences were observed. There were medium effect sizes (ESs) for PP with BANDS (ES = 0.58 at 10 minutes), CS30 (ES = 0.53 and 0.64 at 7 and 10 minutes, respectively), and CS + BANDS (ES = 0.64, 0.78, and 0.66 at 4, 7, and 10 minutes, respectively). All remaining ES for JH and PP were trivial to small. Based on the moderate magnitude of effect, BANDS, CS30, and CS + BANDS were effective at potentiating vertical jump power. CS + BANDS is a more practical approach to potentiate vertical jump power when athletes are under strict time restraints.
尼克森、BS、威廉姆斯、TD、斯纳、RL 和朴 K-S。在抗阻训练男性中，组间休息和弹性带对跳跃增强的单独和联合作用。《力量与体能研究杂志》33（8）：2087-2093，2019-本研究旨在确定在抗阻训练男性中，组内集中组（CS）和弹性带对跳跃增强的单独和联合作用。12 名抗阻训练男性（年龄：22±3 岁）参与了本研究。以随机顺序，参与者完成了 1 组 3 次重复，强度为 85%的 1 次重复最大的平行深蹲：（a）传统组，连续重复；（b）连续重复带弹性带（BANDS）；（c）每组间休息 30 秒的 CS（CS30）；和（d）每组间休息 30 秒并带弹性带的 CS（CS + BANDS）。在每个条件下，在运动前（基线）和运动后 1、4、7 和 10 分钟测量垂直跳跃高度（JH）和峰值功率（PP）。结果表明，BANDS 组在 10 分钟时的 PP 明显高于 7 分钟（p=0.035），CS + BANDS 组的 4 分钟和 7 分钟均明显高于基线（p=0.008 和 0.031）。没有观察到其他差异。PP 与 BANDS（ES=0.58 在 10 分钟时）、CS30（ES=0.53 和 0.64 在 7 和 10 分钟时）和 CS + BANDS（ES=0.64、0.78 和 0.66 在 4、7 和 10 分钟时）的 ES 为中等。JH 和 PP 的所有剩余 ES 均为微小至小。基于适度的效应大小，BANDS、CS30 和 CS + BANDS 对增强垂直跳跃力量有效。当运动员受到严格时间限制时，CS + BANDS 是增强垂直跳跃力量的更实用方法。
