Efeitos da suplementação aguda de aspartato de arginina na fadiga muscular em voluntários treinados

Abstract: A atividade física influi em mecanismos específicos responsáveis pela redução da produção de força e conseqüentemente à fadiga. A preocupação em melhorar o desempenho físico tem sido propostos; observamos que estudos dão atenção para reduzir acúmulos dos metabólitos que diminuem a fadiga durante o exercício físico intenso, usando aminoácidos conhecidos por induzir mudanças metabólicas, entre eles a arginina. O presente estudo teve como objetivo estudar o efeito da suplementação aguda de aspartato de arginina e… Show more

“…12 L-arginine is the precursor of important biological molecules and it is the substrate for different and important enzymes such as nitric oxide synthase (NOS), which catalyzes the formation of nitric oxide (NO). 13 On the other hand, NO is an unconventional neurotransmitter involved with synaptic plasticity during brain development, refinement of neural circuits in adults, as well as having an important role in regulating blood flow. 14,15 It has been documented that the administration of 300 mg/kg L-arginine during the period of fast brain development influences brain electrophysiology in rats.…”

“…This last idea takes grounding in the principle that first, the accumulation of lactate is an indication of the glycogen depletion, with high concentrations of lactate in the fatigue point (10)(11)(12) ; and second, the lactic acid is the great responsible for the muscular pain mentioned during exercise practice. Besides that, Yaspelkis and Ivy 1999 (13) affirm that arginine supplementation reduces the oxidation of post-exercise carbohydrate being able thus to increase the glucose availability for the reestablishment of muscular glycogen supplies during recovery.…”
