The purpose of this study was to analyze the acute effect of static stretching on the performance of multiple sets in the bench press (BP) exercise. Fifteen men (26.2 ± 0.7 years, 72.4 ± 1.3 kg, 1.78 ± 0.1 m, 22.8 ± 0.3 kg·m) performed 4 sets of the BP exercise at 80% of 1 repetition maximum until concentric failure, both in the stretching condition (SC) and control condition (CC). The rate of force decline between the first and the fourth set was used as fatigue index. A randomized, counterbalanced, crossover design was performed with 48 hours between each session. Two static stretching exercises (pectoral and triceps brachii muscles) were performed in a single set before BP in SC, whereas in CC, subjects remained at rest for 150 seconds. For each stretching exercise, the muscle was held at the maximal stretched position for 30 seconds. No significant difference (p > 0.05) was identified for total repetitions performed in 4 sets (SC, 21.3 ± 0.7% vs. CC, 20.5 ± 0.7%) and in the fatigue index (SC, 75.5 ± 1.3% vs. CC, 73.2 ± 1.9%). The results suggest that the performance of multiple sets in the BP exercise does not seem to be influenced by previous static stretching.
本研究旨在分析静态伸展对卧推（BP）练习多组运动表现的急性影响。15 名男性（26.2±0.7 岁，72.4±1.3kg，1.78±0.1m，22.8±0.3kg·m）在伸展条件（SC）和对照条件（CC）下，以 1 次最大重复的 80%进行 4 组 BP 练习，直至达到向心失败。第一组和第四组之间的力下降率被用作疲劳指数。采用随机、平衡、交叉设计，两次测试之间间隔 48 小时。在 SC 中，在 BP 前进行一次单组的两种静态伸展运动（胸肌和肱三头肌），而在 CC 中，受试者保持静止 150 秒。对于每一次伸展运动，肌肉保持在最大伸展位置 30 秒。在 4 组的总重复次数（SC，21.3±0.7%对 CC，20.5±0.7%）和疲劳指数（SC，75.5±1.3%对 CC，73.2±1.9%）方面，没有显著差异（p＞0.05）。结果表明，先前的静态伸展似乎不会影响 BP 练习的多组运动表现。
