Bolus L‐arginine supplementation in the fed state at rest and following resistance exercise does not effect bulk muscle blood flow

The release of nitric oxide from the vascular endothelium results in vasodilation, which in turn increases local blood flow. Although it is known that L‐arginine is the primary substrate for nitric oxide synthase (the enzyme responsible for nitric oxide production) the effect of a bolus oral dose of L‐arginine on blood flow has not previously been studied. The present study was designed to elucidate the effects of post‐exercise L‐arginine …
