Tufano, JJ, Conlon, JA, Nimphius, S, Oliver, JM, Kreutzer, A, and Haff, GG. Different cluster sets result in similar metabolic, endocrine, and perceptual responses in trained men. J Strength Cond Res 33(2): 346-354, 2019-The purpose of this study was to compare the kinematic, metabolic, endocrine, and perceptual responses of 3 back squat protocols with equal loads, number of repetitions, and total rest duration. Eight strength-trained men performed 36 back squats using 75% 1 repetition maximum and 420 seconds of total rest during basic cluster sets of 4 (CS4), rest redistribution sets of 4 (RR4), and rest redistribution sets of 1 (RR1). Rating of perceived exertion (RPE), blood lactate (La), mean velocity maintenance (MVM), and mean velocity loss (MVL) were measured during exercise. Total testosterone (TT), growth hormone (GH), cortisol (C), and sex hormone-binding globulin (SHBG) were measured before exercise and 15, 30, and 60 minutes postexercise. There were no differences between protocols for MVM. However, MVL was less during RR1 compared with RR4 (p = 0.032), and neither protocol was different than CS4. All protocols resulted in similar increases in RPE and La, which remained elevated up to 30 minutes postexercise (p ≤ 0.05). In all protocols, GH increased and returned to baseline by 60 minutes postexercise (p ≤ 0.05). At 60 minutes postexercise, TT was less than all other time points (p ≤ 0.05). There were no main effects for time for SHBG or C. The data from this study show that different types of cluster set protocols can result in proanabolic physiological responses to resistance training. In addition, coaches can redistribute rest periods without affecting perceived effort or metabolic and hormonal changes if the external load, number of repetitions, and total rest time are equalized.
图法诺、JJ、康伦、JA、尼菲厄斯、S、奥利弗、JM、克鲁泽、A 和哈夫、GG。不同的集群设置导致训练有素的男性在代谢、内分泌和感知方面产生相似的反应。J 力量与调节研究 33(2):346-354，2019 年-本研究的目的是比较 3 种后深蹲方案的运动学、代谢、内分泌和感知反应，这些方案的负荷、重复次数和总休息时间相等。8 名力量训练男性使用 75%1 次最大重复次数和 420 秒总休息时间进行 36 次后深蹲，在基本集群设置 4 个（CS4）、重新分配休息设置 4 个（RR4）和重新分配休息设置 1 个（RR1）。运动期间测量了感觉用力等级（RPE）、血乳酸（La）、平均速度维持（MVM）和平均速度损失（MVL）。运动前和运动后 15、30 和 60 分钟测量总睾酮（TT）、生长激素（GH）、皮质醇（C）和性激素结合球蛋白（SHBG）。在 MVM 方面，方案之间没有差异。然而，RR1 时 MVL 低于 RR4（p=0.032），且与 CS4 无差异。所有方案均导致 RPE 和 La 相似增加，运动后 30 分钟仍保持升高（p≤0.05）。在所有方案中，GH 增加并在运动后 60 分钟恢复到基线（p≤0.05）。运动后 60 分钟时 TT 低于其他所有时间点（p≤0.05）。SHBG 或 C 无时间主效应。本研究数据表明，不同类型的集群设置方案可对抗阻训练产生促合成代谢的生理反应。此外，如果外部负荷、重复次数和总休息时间相等，教练可以重新分配休息时间，而不会影响感知用力或代谢和激素变化。
