Fifteen amateur weightlifters, between the ages of 21 and 35 years, volunteered to participate in a study to determine the effect of an amino acid supplement on muscle size, muscle strength, body composition, and body weight. A blind protocol was followed in which eight of the participants were administered the amino acid supplement and seven received a placebo. Each subject was tested before and immediately after the ten week experimental period for height, weight, skinfolds, hydrostatic weighing, body circumferences, static strength, and dynamic strength; Post supplementation, independent T tests indicated that the differences in percent body fat, weight, circumference measurements, static strength, and dynamic strength between the amino acid group and the control group were not significant. It was, therefore, concluded that the amino acid supplement administered in this study had no measured effect on percent body fat, body weight, muscle size, and muscle strength of the participating subjects.
