Abstract

Purpose: One of the strategies used by athletes to improve performance in many sports is to take supplements before the main competition. The purpose of this research is to compare the effect of a period of beta-alanine and sodium bicarbonate supplementation on pH, blood lactate and anaerobic capacity of elite taekwondo men.
Method: 20 elite taekwondo players were divided into two groups of 10 people. Taekwondo athletes consumed 3.2 grams of beta-alanine and 0.3 grams of sodium bicarbonate by weight during 6 weeks. Blood samples and anaerobic capacity were evaluated in two stages, before and 24 hours after the end of 6 weeks of training. For statistical description The mean and standard deviation of the data were used, and the correlated t test was used for the inferential analysis of the data. A significance level of P≤0.05 was considered.
Findings: Taking beta-alanine and sodium bicarbonate supplements together with taekwondo exercises prevented the increase in pH and lactate levels and subsequently increased anaerobic power. Beta-alanine supplement with a daily dose of 2.3 grams compared to sodium bicarbonate supplement with a dose of 0.3 grams can probably be equally effective in preventing fatigue and increasing strength in athletes, and probably beta-alanine supplementation with a dose of more than 2.3 grams Compared to the daily dose of 0.3 grams of sodium bicarbonate, it can have a greater effect in preventing fatigue and increasing energy.
Conclusion: Taekwondo sports activity, along with beta-alanine and sodium bicarbonate supplements, prevents the increase of blood pH and blood lactate. It also improves anaerobic power performance.
