Effects of a Low-Dose Amino Acid Supplement on Adaptations to Cycling Training in Untrained Individuals
The purpose of this study was to determine if amino acid supplementation influences blood and muscle lactate response to exercise and the time course of the metabolic adaptations to training. Two groups of untrained males (n=7 each) were given (double-blind) a daily supplement (2.9 g ⋅ ) containing a mixture of leucine, isoleucine, valine, glutamine. and carnitine (EXP) or 3 g ⋅ of lactose (CON). Following 7 days of supplementation there was no significant change in VO,peak, time to exhaustion (TTX)at 120% . or muscle and blood lactate in either EXP or CON. Subjects then initiated 6 weeks of combined aerobic and anaerobic training on a Monark cycle ergometer. It was found that amino acid supplementation had no effect on either blood or muscle lactate accumulation during exercise, while supplementation resulted in a faster adaptation in buffer capacity. Performance during intense exercise was not improved with amino acid supplementation.
