This study was designed to investigate the effects of β-alanine (BA) supplementation on peak power, power drop, and lactate response in elite male amateur boxers. Nineteen male Korean national team boxers were divided into groups with either BA (n=9) or placebo (PL, n=10) supplementation. BA consumed 4.9–5.4 g/day of BA with training for 10 weeks and PL took PL in a similar manner. Physical fitness and lactate changes in sparring were measured before and after the 10-week inter-vention. Significant interactions (P<0.05) were shown for lower body peak power (P=0.049) and upper body power drop (P=0.042). Positive effects for the BA group were shown for lower body peak power (Co-hen d=0.72; 95% confidence interval [CI], 0.09–1.35) and the mainte-nance of upper body power output (d=-0.91; 95% CI, -1.61 to -0.17). These findings suggest that Korean national amateur boxers who con-sumed BA demonstrated differential responses following a training in-tervention in specific physical fitness when compared to boxing ath-letes who consumed a PL.
