EFEITOS DA SUPLEMENTAÇÃO DE AMINOÁCIDOS DE CADEIA RAMIFICADA (AACR) E EXERCÍCIO FÍSICO: REVISÃO DE LITERATURA

The use of food supplements has grown exponentially, either to fill a gap left by food and / or, mainly as an ergogenic resource. Those classified as protein are among the main ones used, among them, BCAA (Branched Chain Amino Acids). Thus, the general objective of the present literature review was to deepen the knowledge regarding BCAA supplementation and its effects on physical exercise. The bibliographic survey was made operational by searching for complete articles indexed in the PubMed and ScieElo databases, published between the years 2005 to 2019 and which addressed BCAA supplementation in physical exercise. Reduced central fatigue, increased protein synthesis, reduced body fat, saved muscle glycogen stores, strengthened immune system, reduced muscle damage due to intense exercise are some effects suggested as benefits of BCAA supplementation, however the literature presents controversial data, with the majority of these effects not being properly clarified and proven, requiring a greater range of studies with a larger sample size and a longer period of execution.
