L-arginine Improves Exercise Performance in Cyclists

Chen et al. (2010) J Int Soc Sports Nutr. 7:13.

Study: A randomized double-blinded and placebo-controlled trial. Sixteen male cyclists were randomized to receive either L-arginine supplement or a placebo powder. Exercise parameters were assessed by maximal incremental exercise testing performed on a stationary cycle ergometer using breath-by-breath analysis at baseline, week one and week three.

Results: The anaerobic threshold for the supplement groups was significantly higher than that of placebo group at week 1 and week 3.

Conclusion: L-arginine supplement increased the anaerobic threshold at both week one and week three in cyclists.
