Popis: Effects of oral L-arginine supplementation on vasodilation and O2max in male soccer players Study aim: To determine the effects of oral L-arginine supplementation on vasodilation, blood flow and maximum oxygen uptake (O2max) in soccer players. Material and methods: A group of 24 healthy male soccer players aged 20 - 26 years volunteered to participate in the study. The subjects were randomly assigned into 3 groups: experimental, placebo and control. Experimental group was given L-arginine (6 g orally) and the placebo group - starch (6 g orally) daily for a week; subjects from the control group remained untreated. Before the test and at the end of the week blood samples were collected, and systemic blood pressures, blood flows and maximal oxygen uptake (O2max, by Queens College step test) were recorded. Blood samples were assayed for HDL, LDL, triglyceride and urea concentrations. The study was conducted in a randomised, single-blinded, placebo-controlled fashion consisting of 7-day treatment periods. Results: Oral supplementation of L-arginine significantly (p2max (p Conclusions: Oral supplementation of L-arginine may have beneficial effect on vasodilation and O2max, therefore may increase the exercise capacity of soccer players.
