Abstract
Purpose: This study determined the effects of 8 weeks of heavy resistance training combined with branched-chain amino acid (BCAA) supplementation on body composition and muscle performance. Methods: Resistance training was performed by 19 non-resistance-trained males (three sets of 8–10 repetitions) four times/week, for 8 weeks, while also ingesting 9 g/day of BCAA or 9 g/day of placebo (PLAC) on the exercise days only (one-half of total dose 30 min before and after exercise). Data were analyzed with separate 2 × 2 analysis of variance (ANOVA) (p < 0.05). Results: For total body mass, neither group significantly increased with training (p = 0.593) and also, there were no significant changes in total body water (p = 0.517). In addition, no training- or supplement-induced (p = 0.783) changes occurred with fat mass or fat-free mass (p = 0.907). Upper-body (p = 0.047) and lower-body strength (p = 0.044) and upper- (p = 0.001) and lower-body muscle endurance (p = 0.013) increased with training; however, these ...
Highlights
This study determined the effects of eight weeks of heavy resistance training combined with branched-chain amino acid (BCAA) supplementation on body composition and muscle performance
When combined with heavy resistance training for eight weeks, 9 g/day of BCAA supplementation, half given 30 min before and after exercise, had no preferential effects on body composition and muscle performance
For total body mass, neither group significantly increased with training (p = 0.593), and there were no significant changes in total body water (p = 0.517)
