Background and Objective: Dietary supplements are a common strategy used by athletes and adults to improve physical function and recovery, and muscle mass. Beta-alanine (βA) is an inessential amino acid that can improve the performance of athletes. βA is one of the dietary supplements involved in delaying or reducing fatigue and is of interest to athletes, coaches, and sports scientists. This study aimed to investigate the effect of 4-week βA supplementation on soccer athletes' onset of blood lactate accumulation (OBLA) in leg and chest press training volume and running time of 800 m. Materials and Methods: A total of 20 football athletes were randomly divided into two βA supplement and placebo groups. The supplement group (6.4 g of βA per day) and placebo group (6.4 g of starch per day) were eaten for 4 weeks after the briefing session and pretest on blood lactate concentration indices, leg and chest press volume training, and running time of 800 m. Functional evaluations and posttest blood samples were collected from the individuals on day 28. Results: The findings show that OBLA considerably rose right away following activity in both the supplement and placebo groups. It fell in both groups 15 min after activity, with the supplement group showing a significant difference (P ≥ 0.05). In either research group, as well as between pretest and posttest times, there was no statistically significant difference in the training volume of the chest press and leg press activity (P ≥ 0.05). There was a significant temporal interaction of 800 m between the supplement and placebo groups. Conclusion: Short-term βA supplementation reduced OBLA during the postexercise recovery period, while no effect on footballers' performance was observed in these tests.
