Design and methods: Fifteen karate men were chosen to participate in this study (age of 22/3 ± 2/1 years; height 172/6 ± 3/6 cm; weight 67/8 ± 5/2 kg). All subjects performed 7 sessions of squat & bench press with 48 h intervals. At the first session, IRM was measured. During the rest 6 sessions, athletes performed 4 times squat & bench press with 90% (IRM) at each session, one of three different rest intervals (60, 180, 225 seconds) were used randomly between sets. Number of repetitions performed & repetition sustainability between different rest intervals were recorded. Results with Boneferoni method showed that each three different rest intervals caused decline in repetitions in squat &bench press. The repetition decline was significant in the bench press and squat. Repetition sustainability in 225 s in compare to 60 & 180 s was more significant. Repetition sustainability also was higher in 180 s in compare to 60 s. On basis of findings from this study, we can recommend for best performance in bench press & squat, rest intervals of 225 s, to maintain consecutive repetitions.展开更多
