The purpose of this study was to evaluate a dietary supplementation containing arginine, which is one of the latest ergogenic aids for enhancing strength, power, and muscle recovery combined with resistance training. Sixteen young resistance-trained women (age, 22.7 ± 0.6 yrs, BMI, 22.0 ± 2.09 kg·d-1) were randomly assigned to the Supplementation Group (N = 8, 7 days, 0.1 g·kg-1·BW-1) or the Placebo Group (N = 8, Rice flour with capsules of same size and shape). The subjects performed a similar resistance exercise (bench press and leg press exercises, 3 sets × 10-repetition maximum) in both groups before and after 7 days. The findings indicate that the concentration of lactate after 7 days of arginine supplementation was lower than the concentration of lactate in the Placebo Group (P = 0.01). The decrease in lactate production after resistance exercise is the most important finding of this study. However, while increasing the production of lactate in high intensity resistance exercise is a reasonable finding, the profound effect of arginine may be the result of NO-mediated glycolysis inhibition, especially in the female subjects. On the other hand, the inconsistency of other metabolites with lactate may have been related to the time of blood sampling, because it seems there were more latent responses to blood rather than lactate.
