Jagim, AR, Wright, GA, Brice, AG, and Doberstein, ST. Effects of beta-alanine supplementation on sprint endurance. J Strength Cond Res 27 (2): 526–532, 2013—Recent research has shown that beta-alanine (BA) supplementation can increase intramuscular carnosine levels. Carnosine is an intramuscular buffer, and it has been linked to improvements in performance, specifically during bouts of high-intensity exercise that are likely limited by muscle acidosis. Therefore, the purpose of this study was to examine the effect of BA supplementation on sprint endurance at 2 different supramaximal intensities. Twenty-one anaerobically trained (rugby players [n= 4], wrestlers [n= 11], and recreationally strength trained athletes [n= 6]) college-aged men participated in a double-blind, placebo controlled study. The subjects performed an incremental V [Combining Dot Above] O 2 max test and 2 sprint to exhaustion tests set at …
