L-Arginine @5g/Day Reduces Lactate Levels in Male Athletes
While the NO-hype of the last years unquestionably is/was a scam, l-arginine, the amino acid that does not build muscle via increased NO-production, transpires to be ergogenic via very different mechanisms. Scientists from Iran ( Mozezzaneh. 2010 ) have now found that 5g of supplemental l-arginine significantly decreased the blood lactate levels of athletes (N=30) in the course of a 3 week supplementation period, but failed to induce consecutive or concurrent increases in VO2 max (a direct marker of exercise capacity): Blood lactate level was significantly decreased in the L-arginine group compared to the placebo one. There was no significant difference between the two groups in VO2max at anaerobic threshold. Only in the L-arginine group, VO2 max at anaerobic threshold was significantly increased. In addition, there was no significant difference in VO2 max at anaerobic threshold for the placebo group. If you remember the previous news on arginine , you may understand that I will r...
