THE EFFECTS OF VARIED REST PERIODS BETWEEN SETS TO FAILURE USING THE BENCH PRESS IN RECREATIONALLY TRAINED MEN

The purpose of this study was to determine the rate of recovery for recreational weight trainers between 2 sets of bench press to volitional exhaustion. Twenty-eight men performed 2 sets of the bench press at 75% of their previously determined 1 repetition maximum (1RM) to volitional exhaustion. Rest periods of 1, 3, or 5 minutes between sets were utilized on the 3 separate testing days. There was a significant decrease in the number of repetitions performed between the second sets at all rest periods. There were no significant differences in work performed (repetitions × weight) during the second set with the 3- and 5-minute rest periods, but the total work with a 1-minute rest period (1,389.1 ± 529.9) was significantly less than both the 3- (1,494.9 ± 451.0) and 5-minute (1,711.4 ± 478.0) rest period. The data indicated that subjects were unable to fully recover between the first and second sets of maximal resistance exercise, regardless of the rest period. However, subjects were able to maintain a performance level of 8–12 repetitions and sustain the total work performed per set with as little as 3 minutes rest between sets.
