Vibration exercise (VbX) has gained popularity as a warm-up modality to enhance performance in golf, baseball, and sprint cycling, but little is known about the efficacy of using VbX as a warm-up before resistance exercise, such as deadlifting. The aim of this study was to compare the effects of a deadlift (DL)-specific warm-up, VbX warm-up, and Control on DL power output (PO). The DL warm-up (DL-WU) included 10, 8, and 5 repetitions performed at 30, 40, and 50% 1-repetition maximum (1RM), respectively, where the number of repetitions was matched by body-weight squats performed with vibration and without vibration (Control). The warm-up conditions were randomized and performed at least 2 days apart. Peak power (PP), mean power, rate of force development (RFD), and electromyography (EMG) were measured during the concentric phase of 2 consecutive DLs (75% 1RM) at 30 seconds and 2:30 minutes after the warm-up conditions. There was no significant (p > 0.05) main effect or interaction effect between the DL-WU, VbX warm-up, and Control for PP, mean power, RFD, and EMG. Vibration exercise warm-up did not exhibit an ergogenic effect to potentiate muscle activity more than the specific DL-WU and Control. Therefore, DL PO is affected to a similar extent, irrespective of the type of stimuli, when the warm-up is not focused on raising muscle temperature.
振动训练（VbX）作为一种热身方式已越来越受欢迎，可提高高尔夫、棒球和短跑自行车项目的运动表现，但对于将VbX用作诸如硬拉等抗阻训练前的热身效果却知之甚少。本研究的目的是比较特定硬拉热身、VbX热身和对照组对硬拉功率输出（PO）的影响。硬拉热身（DL-WU）分别包括以1次重复最大值（1RM）的30%、40%和50%进行10次、8次和5次重复，其中重复次数与有振动和无振动（对照组）的体重深蹲相匹配。热身条件随机安排，且至少间隔2天进行。在热身条件结束后30秒和2分30秒时，在连续两次硬拉（75% 1RM）的向心阶段测量峰值功率（PP）、平均功率、力量发展速率（RFD）和肌电图（EMG）。对于PP、平均功率、RFD和EMG，硬拉热身、VbX热身和对照组之间没有显著的（p>0.05）主效应或交互效应。与特定的硬拉热身和对照组相比，振动训练热身并未表现出增强肌肉活动的促力效应。因此，当热身不专注于提高肌肉温度时，无论刺激类型如何，硬拉功率输出受到的影响程度相似。
