Abstract :
Introduction: Rowing is one of the oldest sports and its competition has been held every four years at the Olympic games and is considered as one of the greatest world championship. The aim of this study is to investigate the effect of acute beta-alanine supplementation on the Tmax, record of 6 minutes on rowing ergo-meter and Vo2max and blood lactate responses in the Iranian national team members of rowing. Materials and Methods: 15 elite male rowers (age: 22.5 ± 4.9, Height: 186.8 ±8.3cm, weight: 80.3 ± 4.9 kg body fat: 8.8± 2.7 percent) voluntarily participated in this study. Rowers were in training camp and preparing for competetion. The subjects were randomly divided into two groups: placebo (control) and supplement groups (experimental). Subjects were supplemented every 4 hours, 3 hours and 2 hours with10 mg per kg of body weight with betaalanine or placebo (glucose) in a cross-over design before the 6-minute and Tmax test on rowing ergo-meter with free rhythm. Tests concerned with rowing ergometer and Tmax and blood lactate before and after 6 minutes test were carried out. Independent t-test and SPANOVA were used for statistical analyses. Results: The results did not show differences among the groups for all the variables (p>0.05), except, Tmax that increased significantly in beta-alanine group. This study showed that acute beta-alanine administration could increase Tmax significantly. Conclusion: According to the results, beta-alanine supplementation could improve rower’s record and postpone their fatigue and improve rower’s stamina to increase the time for exhaustion.
