The purpose of the present 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 three bench press protocols in random order consisting of 3 sets of up to 10 repetitions with 75% of one repetition-maximum (1RM) using either 1-, 2-, or 3-min RIs between sets. In the first cohort, twenty-two men and women were studied to investigate gender influence. In the second cohort, twenty-three 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-min (26.9 ± 4.4 vs. 21.1 ± 3.5), 2-min (29.0 ± 2.0 vs. 24.0 ± 4.5), and 3-min (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 women. Total number of repetitions performed was significantly greater in the low-1RM group than the high-1RM group at 1-min (21.6 ± 5.0 versus 18.1 ± 2.0) and 2-min RIs (24.2 ± 5.4 versus 21.3 ± 2.8). Significant negative correlations were observed between 1RM bench press and total number of repetitions completed for 1- and 2-min 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 shorter RIs may suffice in women in order to attain a specific volume.
