Comparison of Repetition Number between Uni-Joint and Multi-Joint Exercises with 1-Min and 2-Min Rest Intervals. JEPonline 2014;17(4):93-101. The aim of this study was to compare the maximum number of repetitions performed using uni-joint and multi-joint exercises with either a 1-min or a 2-min rest interval. Eighteen male subjects subjected to two types of resistance exercise: peck deck fly and bench press. Four tests were performed in random order (exercise x recovery interval): Peck deck fly and bench press with either a 1-min or a 2-min rest interval between sets. The tests consisted of 3 sets with a load equal to the individual’s 10 repetition maximum (10 RM), each set performed to failure. The amount of work performed for all sets was significantly higher for the 2-min recovery intervals when compared to the 1-min recovery intervals. The maximum number of repetitions with the 1-min interval was statistically higher for the peck deck fly and bench press 94 compared to the 2nd and 3rd sets. However, a greater absolute number of repetitions tended to be performed during the 1st set of peck deck fly as compared to the 2nd and 3rd sets. With the 2-min recovery, no differences were found between the number of repetitions achieved between the peck deck fly and bench press exercises. However, the trend remained for a higher number of repetitions for the peck deck fly than the bench press. It was concluded that the 2-min interval was more effective for the multi-joint exercises because it minimizes the drop in the total number of repetitions performed.
