Abstract

Aims: Understanding the effects of sports supplements that can modulate lactate concentrations during intense anaerobic activities is important for athletes. Therefore, the aim of this study was to determine the effect of beta-alanine supplementation on lactate concentration following the Wingate anaerobic test in male athletes.
Methods: The present study was an experimental, randomized, double-blind, placebo-controlled study. The statistical population consisted of semi-professional track and field athletes, of whom 20 male volunteer athletes (age: 22.6±2.5, height: 187.6±2.9, body fat percentage: 12.7±1.58) were randomly assigned to two groups: beta-alanine supplementation (28 days, four doses of 1.6 g/day) and placebo (maltodextrin, 28 days, four doses of 1.6 g/day). Blood samples were collected in three sessions before and after supplementation (before the first test, immediately after the second test, and the third Wingate test).
Results: In the post-supplementation session, lactate levels in the two supplement and placebo groups were significantly different before the first test and after the third test, and its values in the supplement group were lower than in the placebo group (p<0.05).
Conclusion: The findings of this study showed that a 28-day period of beta-alanine supplementation can reduce blood lactate levels during the recovery period in semi-professional track and field athletes.
