The purpose of this study was to investigate the effects of rest interval (RI) length on bench press performance in subjects with disparity in maximum strength. Two cohorts of subjects performed 3 bench press protocols in random order consisting of 3 sets of up to 10 repetitions with 75% of 1-repetition maximum (1RM) using either 1-, 2-, or 3-minute RIs between sets. In the first cohort, 22 men and women were studied to investigate gender influence. In the second cohort, 23 men were tested for 1RM bench press strength and placed into a low 1RM (mean = 80.7 ± 7.5 kg) or high 1RM (mean = 140.6 ± 11.9 kg) experimental group. The number of successful repetitions completed, average power, and velocity for each set were recorded. Women performed significantly more repetitions than men with 1-minute (26.9 ± 4.4 vs. 21.1 ± 3.5), 2-minute (29.0 ± 2.0 vs. 24.0 ± 4.5), and 3-minute (29.7 ± 1.8 vs. 25.8 ± 5.1) RIs. The magnitude of decline in average velocity and power was significantly higher in men than in women. Total number of repetitions performed was significantly greater in the low 1RM group than in the high 1RM group at 1-minute (21.6 ± 5.0 vs. 18.1 ± 2.0) and 2-minute RIs (24.2 ± 5.4 vs. 21.3 ± 2.8). Significant negative correlations were observed between 1RM bench press and total number of repetitions completed for 1- and 2-minute RIs (r = -0.558 and -0.490, respectively). These data indicate that maximal strength plays a role in bench press performance with varying RIs and suggest that shorter RIs may suffice in women to attain a specific volume.
这项研究的目的是探讨休息间隔（RI）长度对最大力量差异的受试者卧推表现的影响。两组受试者以随机顺序进行 3 项卧推方案，每组 3 组，每组 10 次，使用 75%的 1 次重复最大重量（1RM），组间休息时间分别为 1 分钟、2 分钟或 3 分钟。在第一组中，研究了 22 名男性和女性，以调查性别影响。在第二组中，23 名男性进行了 1RM 卧推强度测试，并分为低 1RM（平均值=80.7±7.5kg）或高 1RM（平均值=140.6±11.9kg）实验组。记录了每组完成的成功重复次数、平均功率和速度。女性完成的重复次数明显多于男性，1 分钟（26.9±4.4 比 21.1±3.5）、2 分钟（29.0±2.0 比 24.0±4.5）和 3 分钟（29.7±1.8 比 25.8±5.1）RI。男性的平均速度和功率下降幅度明显高于女性。低 1RM 组的总重复次数明显高于高 1RM 组，1 分钟（21.6±5.0 比 18.1±2.0）和 2 分钟 RI（24.2±5.4 比 21.3±2.8）。1RM 卧推与 1 分钟和 2 分钟 RI 完成的总重复次数之间观察到显著的负相关（r=-0.558 和-0.490）。这些数据表明，最大力量在不同 RI 的卧推表现中起作用，并表明较短的 RI 可能足以使女性达到特定的容量。
