The Effects of Chronic Arginine Supplementation on Muscle Strength and Hypertrophy Following Resistance Training

Abstract Details

2015, Honors Theses, Ohio Dominican University, Honors Theses.
Arginine is known to be the only precursor in the human body to stimulate nitric oxide (NO) production. NO induces vasodilation via smooth muscle relaxation allowing for increased blood flow and greater waste removal at the tissue. PURPOSE: The purpose of this study was to determine whether or not arginine supplementation increased muscle strength and hypertrophy when compared to a placebo group. METHODS: Nine male subjects were designated into one of three groups: 1) placebo, 2) Arginine supplementation 20 minutes prior to exercise, and 3) Arginine supplementation two hours post exercise. The experimental groups consumed 6g of arginine before or after each workout. The placebo group consumed 6g of capsulated powdered sugar 20 minutes prior to exercise. Three compound lifts (chest press, leg press, shoulder press) were performed three times per week for four total weeks. A 1 repetition maximum (1RM) was performed for all three lifts on the first day of training and the last day of training. Skin fold analysis was performed on the same days as the 1RM to account for body composition changes. RESULTS: Strength performance and muscle hypertrophy of participants in both experimental groups showed no significant increase compared to the placebo group (p>0.05). CONCLUSION: The results of this study showed all groups to increase in strength performance following a 4-week resistance training regime but it was found that the experimental groups showed no significant difference compared to the placebo group. Arginine administration failed to significantly increase strength performance and muscle hypertrophy.
