Abstract

The aim of this study was to examine the acute metabolic response, neuromuscular activity, and mechanical performance of different set configurations in bench-press (BP). Twenty-two resistance-trained men performed three resistance exercise protocols consisting of 3 x 12 BP repetitions at 60% 1RM, with 4 minutes of rest between sets, but with different set configurations: (a) traditional set (TS), without rest within the set; (b) cluster-6 (CS6), with 30-second intraset rest after the sixth repetition in each set; and (c) cluster-2 (CS2), with 30-second intraset rest every two repetitions. Mean propulsive force (MPF), velocity (MPV), power (MPP), and electromyography (EMG) values were recorded for each repetition. Blood lactate, maximal voluntary isometric BP contraction, and dynamic strength in BP were assessed pre- and post-exercise. The CS2 protocol resulted in greater mechanical performance (i. e. MPF, MPV, and MPP) and lower alterations of EMG parameters (i. e. root mean square and median frequency) during the exercise compared to CS6 and TS (TS

对不同组的急性代谢反应、神经肌肉活动和机械性能。

本研究旨在考察卧推（BP）中不同组别配置的急性代谢反应、神经肌肉活动和机械性能。22 名阻力训练男子进行了三种阻力训练方案，包括以 60% 的 1RM 重复 3 x 12 次卧推，每组之间休息 4 分钟，但采用了不同的组套配置：（a）传统组套（TS），组内无休息；（b）组群-6（CS6），每组第六次重复后组内休息 30 秒；以及（c）组群-2（CS2），每两次重复后组内休息 30 秒。记录每次重复的平均推进力（MPF）、速度（MPV）、功率（MPP）和肌电图（EMG）值。对运动前后的血乳酸、最大自主等长 BP 收缩和 BP 动态强度进行了评估。与 CS6 和 TS 相比，CS2 方案在运动过程中产生了更高的机械性能（即 MPF、MPV 和 MPP）和更低的肌电图参数变化（即均方根和中位频率）（TS
