Boffey, D, Sokmen, B, Sollanek, K, Boda, W, and Winter, S. Effects of load on peak power output fatigue during the bench throw. J Strength Cond Res 33(2): 355-359, 2019-The ability to create power is an important variable for athletic success. No study to date has compared peak power output (PPO) fatigue across multiple sets and with different loads with the bench throw. This study aimed to begin the process of establishing empirical upper-body power training guidelines for moderately strong athletes by determining how load (30, 45, and 60% 1 repetition maximum [1RM]) affects PPO (Watts) dropoff during 3 sets of 10 repetitions of the bench throw. Ten resistance-trained male volunteers ([mean ± SD]: age 20.58 ± 1.36 years, height 176.05 ± 9.09 cm, body mass 78.65 ± 9.93 kg, bench press 1RM 99.79 ± 18.52 kg) performed 3 sets of 10 repetitions of the bench throw with one of the 3 loads during 3 weekly sessions. A Humac 360 device collected concentric phase PPO data during each repetition. The data were analyzed using one-way (treatment) and 2-way (treatment × time) repeated-measures analysis of variance. A significant decrease in PPO was observed during repetitions 5-7 at 30%, 3-4 at 45%, and 2-3 at 60% 1RM. Based on the results of this study, coaches who want to maximize power should potentially keep sets of upper-body plyometrics within these repetition ranges. The authors recommend that moderately strong athletes perform the bench throw on a Smith machine at 45% or 60% 1RM to produce high PPO over multiple sets.
博菲、索门、索伦克、博达和温特。负荷对卧推中峰值功率输出疲劳的影响。《体力研究杂志》33(2):355-359，2019 年——产生力量的能力是运动成功的一个重要变量。迄今为止，没有研究比较过多个负荷和不同负荷下的峰值功率输出（PPO）疲劳，而与卧推相比。本研究旨在通过确定负荷（30%、45%和 60%1 重复最大[1RM]）如何影响卧推 3 组 10 次重复中 PPO（瓦特）的下降，开始为中等强度运动员建立经验性的上体力量训练指南。10 名受过抗阻训练的男性志愿者（[均值±标准差]：年龄 20.58±1.36 岁，身高 176.05±9.09 厘米，体重 78.65±9.93 千克，卧推 1RM99.79±18.52 千克）在 3 周内的 3 次训练中分别用 3 种负荷中的 1 种完成 3 组 10 次卧推。Humac 360 设备在每次重复的向心阶段收集 PPO 数据。使用单向（处理）和 2 向（处理×时间）重复测量方差分析对数据进行分析。在 30%1RM 时，第 5-7 次重复时 PPO 明显下降，在 45%1RM 时第 3-4 次重复时，在 60%1RM 时第 2-3 次重复时明显下降。根据这项研究的结果，想要最大限度地提高力量的教练们可能需要将上体增强式训练的组数保持在这些重复范围内。作者建议，中等强度的运动员在史密斯机上以 45%或 60%1RM 进行卧推，以在多组中产生高 PPO。
