DOMINGUEZ, Raúl; LOUGEDO, Juan H.; MATE-MUNOZ, José Luis  and  GARNACHO-CASTANO, Manuel Vicente. Effects of ß-alanine supplementation on athletic performance. Nutr. Hosp. [online]. 2015, vol.31, n.1, pp.155-169. ISSN 1699-5198.

Carnosine, dipeptide formed by amino acids ß-alanine and L-histidine, has important physiological functions among which its antioxidant and related memory and learning. However, in connection with the exercise, the most important functions would be associated with muscle contractility, improving calcium sensitivity in muscle fibers, and the regulatory function of pH. Thus, it is proposed that carnosine is the major intracellular buffer, but could contribute to 7-10% in buffer or buffer capacity. Since carnosine synthesis seems to be limited by the availability of ß-alanine supplementation with this compound has been gaining increasing popularity among the athlete population. Therefore, the objective of this study literature review was to examine all those research works have shown the effect of ß-alanine supplementation on athletic performance. Moreover, it also has attempted to establish a specific dosage that maximizing the potential benefits, minimize paresthesia, the main side effect presented in response to supplementation.

Keywords : Amino acid; Beta alanine; Carnosine; Paresthesia; Sports supplementation.
