摘 要：Aim:Arginine has been classified as a semi-essential or conditionally essential amino *** characterization alludes to the fact that arginine has to be extracted from the diet as a supplement to the endogenous synthesis in growing mammals and in adult animals or humans during disease or trauma;however,arginine can be synthezised in sufficient quantity in the healthy *** aim of this study was to investigate the effect of long term arginine supplementation on Nitric oxide in intermittent anaerobic exercise and the underlying mechanism in well-trained male ***:30 elite male bodybuilder athletes recruited from The clubs of bodybuilding of Tehran participated in this *** subjects were 21.5±0.3 years *** height were 1.71±0.06 *** body weight in arginine(ARG) and control(CON) trials were 69.4±3.8 and 71.3±1.0 kg,*** study used a randomized cross-over,placebo controlled *** subject was randomly assigned to ARG or CON trial *** trial consumed 12 g/day arginine tablets for 6 ***:No significant difference was found between the 2 trials at any time *** both trials,NOx concentration was significantly higher during and 6 min after exercise comparing to the basal *** study suggested that the long-term supplementation of arginine had no effect on plasma NO in intermittent anaerobic tests in well-trained male *** use of arginine supplementation to increase NO production,reduce metabolites accumulation and improve exercise performance in athletes should be critically reevaluated even though it may have beneficial effect in certain patients and general population.
