Abstract/OtherAbstract:
ABSTRACT: The purpose of the present study was to investigate the effects of manipulating rest interval (RI) length of the first upper body exercise in sequence on subsequent resistance exercise performance. Twenty-two men and women with at least 1 year of resistance training experience performed resistance exercise protocols on three occasions in random order. Each protocol consisted of performing four barbell upper-body exercises in the same sequence (bench press, incline bench press, shoulder press, and bent-over row) for 3 sets of up to 10 repetitions with 75% of one repetition-maximum (1RM). Bench press RI were 1, 2, or 3 min while other exercises were performed with a standard 2-min RI. The number of repetitions completed, average power, and velocity for each set of each exercise were recorded. Gender differences were observed during the bench press and incline press as women performed significantly (P ≤ 0.05) more repetitions than men during all RIs. The magnitude of decline in velocity and power over three sets of the bench press and incline press was significantly higher in men than women. Manipulation of RI length during the bench press did not affect performance of the remaining exercises in men. However, significantly more repetitions were performed by women during the first set of the incline press using 3RI than 1RI. In men and women, performance of the incline press and shoulder press was compromised compared to baseline performances. Manipulation of RI length of the first exercise affected performance of only the first set of one subsequent exercise in women. All RIs led to comparable levels of fatigue in men indicating that reductions in load are necessary for subsequent exercises performed in sequence that stress similar agonist muscle groups when ten repetitions are desired.
