- Abstract
The purpose of this study was to compare the influence of different rest interval lengths in multi-joint and single-joint resistance exercises on repetition performance, rating of perceived exertion, and blood lactate. Twelve trained men participated in this study. First, they performed test and retest for 10 repetition maximum in a multi-joint exercise (bench press, BP) and a single-joint exercise (machine chest fly, MCF). Then, all subjects completed four different training sessions. In each session, 5 sets of one exercise were performed with 10 repetition maximum load until fatigue with 1- or 3-min rest interval between sets in a counterbalance crossover design. The 3-min rest interval promoted a greater total number of repetitions in BP and MCF when compared to 1-min rest interval. As to rating of perceived exertion, progressive elevations occurred after the 3rd set in all conditions tested. For blood lactate concentration differences between intervals occurred at the MCF with higher elevations presented at the shorter intervals. Both exercises showed similar patterns on the repetitions performance, but multi-joint exercises led to greater fatigue with longer rest interval.
