PURPOSE The purpose of this study was to determine the effect of glycine-arginine-alpha-ketoisocaproic acid (GAKIC) supplementation on repeated bouts of anaerobic cycling performance. METHODS Ten men completed a randomized, double-blinded, placebo-controlled exercise protocol of two sessions separated by 7 d. Plasma lactate was analyzed in blood collected 45 min before exercise (REST) and 5 min postexercise (POST). Subjects consumed either 11.2-g GAKIC or placebo (PLC) during a 45-min period… CONTINUE READING
