摘要: Ornithine, arginine and citrulline, components of the urea cycle, have recently received attention as sports supplements. Supplementation these amino acids relates nitric oxide (NO) production, ammonia detoxification growth hormone (GH) secretion in body. NO is effective for vessel vasodilatation, which enhances O2 nutrients delivery to working muscle during exercise. Ammonia thought be one causes exercise-induced fatigue metabolized cycle liver. GH affects protein synthesis intake into cells; therefore, supplementation may induce skeletal hypertrophy. Some studies investigated effects humans other mammals. This review focuses on ornithine, citrulline performance considers potential
