Effect of beta alanine on lactate level and Specific performance of elite male rowers

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 & 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. 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). It can be concluded that ingesting beta-alanine might delay lactate accumulation and increases time to exhaustion in rowing performance.
