A popular method to improve athletic performance and lower body power is to train with wearable resistance (WR), for example, weighted vests. However, it is currently unknown what training effect this loading method has on full-body explosive movements such as the power clean. The purpose of this study was to determine what effects WR equivalent to 12% body mass (BM) had on the power clean and countermovement jump (CMJ) performance. Sixteen male subjects (age: 23.2 ± 2.7 years; BM: 90.5 ± 10.3 kg) were randomly assigned to five weeks of traditional (TR) power clean training or training with 12% BM redistributed from the bar to the body using WR. Variables of interest included pre and post CMJ height, power clean one repetition maximum (1RM), peak ground reaction force, power output (PO), and several bar path kinematic variables across loads at 50%, 70%, and 90% of 1RM. The main findings were that WR training: (1) increased CMJ height (8.7%; ES = 0.53) and 1RM power clean (4.2%; ES = 0.2) as compared to the TR group (CMJ height = -1.4%; 1RM power clean = 1.8%); (2) increased PO across all 1RM loads (ES = 0.33-0.62); (3) increased barbell velocity at 90% 1RM (3.5%; ES = 0.74) as compared to the TR group (-4.3%); and (4) several bar path kinematic variables improved at 70% and 90% 1RM loads. WR power clean training with 12% BM can positively influence power clean ability and CMJ performance, as well as improve technique factors.
一种提高运动表现和下肢力量的常用方法是进行可穿戴阻力（WR）训练，例如使用负重背心。然而，目前尚不清楚这种负荷训练方法对诸如高翻等全身爆发性动作有何训练效果。本研究的目的是确定相当于体重（BM）12%的可穿戴阻力对高翻和反向纵跳（CMJ）表现有何影响。16名男性受试者（年龄：23.2±2.7岁；体重：90.5±10.3千克）被随机分配到为期五周的传统（TR）高翻训练组，或使用可穿戴阻力将相当于12%体重的负荷从杠铃重新分配到身体上进行训练的组。感兴趣的变量包括CMJ高度前后、高翻一次重复最大值（1RM）、峰值地面反作用力、功率输出（PO），以及在1RM的50%、70%和90%负荷下的几个杠铃路径运动学变量。主要研究结果表明：与TR组相比，可穿戴阻力训练：（1）提高了CMJ高度（8.7%；效应量=0.53）和高翻1RM（4.2%；效应量=0.2）（CMJ高度=-1.4%；高翻1RM=1.8%）；（2）在所有1RM负荷下提高了功率输出（效应量=0.33 - 0.62）；（3）与TR组相比（-4.3%），在90% 1RM时杠铃速度提高了（3.5%；效应量=0.74）；（4）在70%和90% 1RM负荷下，几个杠铃路径运动学变量得到改善。使用相当于12%体重的可穿戴阻力进行高翻训练可以对高翻能力和CMJ表现产生积极影响，并改善技术因素。
