2g Arginine /Day Induce Vasolidation and Increase VO2Max in Male Soccer Players
Regular readers of the SuppVersity will know that - despite the recent bashing of arginine by the some supplement producers - I like this universal amino acid AND studies supporting the notion of athletes being able to benefit from arginine supplementation keep coming. The most recent one was done by Kamil et al. ( Kamil. 2010 ) and investigated the effect of 2g pure l-arginine on vasolidation and VO2Max in soccer players. Their findings were as follows: Oral supplementation of L-arginine significantly (p<0.01) decreased blood pressure indices and increased VO 2 max (p<0.01), blood flow (p<0.05), femoral artery diameter (p<0.05) and urea levels (p<0.05). There was no change in blood lipid levels (p<0.05). No significant changes were noted in the placebo and control groups. The increase in VO2Max, as shown in Table 1 was relatively low, though. Yet, it's statistical significance stands out of question. L-Arginine Placebo Control ...
