Unexpected Performance Increments in Elite Wrestlers in Response to Well-Timed Arginine Supplementation: 5.8% Increased Time to Exhaustion, No Recution in O2 Cost!
Science is still wrestling with evidence in favor vs. against l-arginine |
Aside from the dosage, which would be on the higher side compared to the average arginine trial, there were no significant differences to study protocols you know.

There was one difference, however. The subjects were not allowed to start working out immediately after they'd washed down the arginine / placebo supplement. Instead, they had to wait for sixty minutes for the arginine peak in plasma (Gannon. 2002).
In that, it is quite astonishing that these improvements occurred in the absence of changes in VO2 consumption. A reduction in O2 cost, as it was reported by Bailey et al. (2009) would after all be the most obvious explanation of the ergogenic effects of arginine.
