ABSTRACTTo examine the effect of an amino acid supplement (AAS), 15 elite athletes volunteered to perform a series of short-term anaerobic power tests. All dependent variables were measured prior to and after 14 days of daily ingestion of an AAS or a placebo in a double-blind, random-order crossover design. Dependent variables included 15 consecutive maximal vertical jumps, six 1O-sec Wingate tests, and a 60-sec Wingate test. Dietary records were analyzed for total calories, % protein calories, % fat calories, % carbohydrate calories, grams of protein, and individual amino acids. No significant difference of any variable examined in all Wingate tests or vertical jump test was found between the placebo or AAS treatments. Neither whole-blood lactate after the Wingate tests nor resting blood ATP differed significantly between the placebo or AAS treatments. Dietary records did not reveaI any significant difference between the placebo or AAS treatments.
