Abstract

Between set rest intervals (RI) are one of the most important variables in resistance training; however, no known research has investigated the effects of RIs greater than 5-min during strength training (>85% of 1RM). The purpose of this research was to examine the effects of three different RIs (2, 5, and 8-minute) on training volume (kg, sets x reps x resistance) and repetition sustainability during a high-intensity bench press exercise (> 85% of 1RM). Fifteen resistance trained males (mean+sd, age = 26+5 yr, height = 161+6 cm, body mass = 79+6 kg, bench press 1RM ratio = 1.39+0.1) completed 3 experimental sessions, during which 4 sets of the bench press were performed with 85% of a 1RM load. During experimental sessions, the bench press was performed with a 2, 5, or 8-minute RI in a random counterbalanced design. Data was analyzed using both a one and two-way ANOVA with repeated measures. As sets progressed, repetitions were significantly different (p < 0.05) between all RIs and only the 8-min RI (p < 0.05) allowed for the complete sustainability of repetitions over four consecutive sets. Greater training volume (p < 0.05) was attained when subjects used an 8-min RI between sets compared to a 2 or 5-min RI. Resistance trained males, with the goal of greater volume during strength training, would benefit from longer RIs; specifically, using an 8-min RI between 4 consecutive sets of a bench press exercise.
