The aim of this study was to compare the effects of rest redistribution (RR) on kinetics and kinematics during the hang pull (HP). Twenty-one male athletes (age 29.5 ± 4.3 years, height 1.78 ± 0.07 m, body mass 75.17 ± 11.11 kg, relative one repetition maximum [1RM] power clean [PC] 1.17 ± 0.14 kg.kg-1) performed the HP using 140% of 1RM PC with 3 traditional sets of 6 repetitions (TS), 9 sets of 2 repetitions with RR [45s rest after 2 repetitions] (RR45) and 6 sets of 3 repetitions with RR [72s rest after 3 repetitions] (RR72). Peak velocity (PV) was higher during RR72 (1.18 ± 0.11 m.s-1) compared to RR45 (1.14 ± 0.11 m.s-1) for the average of 18 repetitions (p = 0.025, g = 0.36). There was a main effect for set configuration with greater peak force (PF) (p < 0.001, g = 0.14) during RR72 compared to RR45, with greater PV and impulse (p < 0.001, g = 0.19-0.36) during RR72 compared to RR45. There was also greater peak velocity maintenance (PVM) (p = 0.042, g = 0.44) for RR72 compared to RR45. There were no significant or meaningful differences (p > 0.05, g = 0.00-0.59) between configurations for any other variables. Rest redistribution protocols did not result in significantly or meaningfully greater kinetics or kinematics during the HP when compared to a TS protocol; although performing RR72 resulted in higher PF, PV, and impulse, with improved PVM compared to RR45.
本研究旨在比较休息重新分配(RR)对悬垂拉起(HP)过程中动力学和运动学的影响。21 名男性运动员(年龄 29.5±4.3 岁,身高 1.78±0.07m,体重 75.17±11.11kg,相对 1 次重复最大力量[1RM]清洁[PC]的功率 1.17±0.14kg.kg-1)使用 1RM PC 的 140%进行 HP,共进行 3 组传统的 6 次重复(TS)、9 组 RR[每 2 次重复后休息 45s](RR45)和 6 组 RR[每 3 次重复后休息 72s](RR72)的 2 次重复。与 RR45(1.14±0.11m.s-1)相比,RR72(1.18±0.11m.s-1)在 18 次重复的平均值中具有更高的峰值速度(PV)(p=0.025,g=0.36)。RR72 与 RR45 相比,在设置配置方面存在主要影响,RR72 的峰值力(PF)(p<0.001,g=0.14)更大,RR72 的 PV 和冲量(p<0.001,g=0.19-0.36)也更大。RR72 与 RR45 相比,峰值速度保持(PVM)(p=0.042,g=0.44)更高。与 TS 方案相比,RR72 和 RR45 之间在任何其他变量上都没有显著或有意义的差异(p>0.05,g=0.00-0.59)。RR 方案在 HP 期间并未导致动力学或运动学显著或有意义地增加,与 TS 方案相比;尽管 RR72 的 PF、PV 和冲量较高,与 RR45 相比,PVM 得到改善。
