Scope: According to the role of beta-alanine in buffering, this study aimed to investigate the effects of chronic beta-alanine ingestion on rowing performance.Materials & Methods: Twenty-four elite male rowers (age:23.4 ±3.3 years, height: 186.1± 7.9 cm, body fat percentage: 8.9 ± 2.1) randomly divided into beta-alanine (40 milligrams. Kilogram-1 body weight per day), placebo (dextrose) or no-supplement for 21 days (n=8). After evaluating Volume of O2 maximum (VO2max) and velocity in VO2max (vVO2max), test of 6 min rowing ergometer for assessing mean power output, mean velocity in 6 minutes rowing maximum (vRmax) and Time at vRmax (TvRmax), and test of 6min ergo rowing with 90% of vRmax were executed in a pre- posttest procedure Power output (P), time to exhaustion (TvRmax), lactate concentration (LA) and heart rate (HR) were recorded from ergo rowing. For analysisng the outputs, ANOVA was utilized. Findings: Significant differences were shown in power output in 6 min@24str, vRmax (p= 0.00), TvRmax and LA in Post-test between beta-alanine and placebo or control (P= 0.00 and P= 0.04 respectively). Conclusion: It can be concluded that ingesting beta-alanine might delay lactate accumulation and increases time to exhaustion in rowing performance.
