Abstract

Introduction: Beta-Alanine is an effective supplement on lactate level which seems to promote the athletic performance. Due to its role on Lactate levels, the aim of this study was to investigate the role of Beta Alanine Supplementation on Lactate level and performance of elite rower. Materials and 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 without-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 rowing machine performance. For analyzing the outputs, ANOVA with bonferroni correction was utilized in 0. 05 level. Results: Lactate was significantly decreased after 6 min test with 90% of vRmax in Beta Alanine Supplementation (P = 0. 00). Also significant increases were shown in average power output (P = 0. 00) TvRmax (P = 0. 04) and vRmax (P = 0. 00) in Post-test between beta-alanine and placebo or control. Conclusion: It seems that ingesting beta-alanine delays lactate accumulation which might promote the aerobic capacity and increases the Time to exhaustion in rowing performance.
