Abstract: Carnosine is a dipeptideof beta-alanine and histidine amino acids, being found in most of the muscle tissue. Its synthesis occurs through carnosine synthase enzyme having the beta alanine as a limiting precursor. The most recent works have shown that increased levels of carnosine improves sports performance due to reducing of decrease in pH intramuscular during exercise, providing greater buffering capacity of hydrogen ions (H +). The aim of this review was to analyze works related to the effects of chronic beta-alanine supplementation on exercise performance recent years. The search strategy was done through consultation with PubMed and Trip Database data using the combined descriptors “carnosine”, “beta-alanine” and “exercise” in articles published between January 2007 and December 2013. We included in this analysis just original articles and articles that evaluated unhealthy sample, beta-alanine supplementation associated with other substances, as well as these, dissertations and reviews were excluded. Based on information meeting, we believe that beta-alanine supplementation can be considered an effective strategy in increasing carnosine levels, reflecting improved performance through increased time to exhaustion and delayed on neuromuscular fatigue threshold, presenting better effects in high intensity activities.
