Abstract
Abstract
Background: Beta-alanine and caffeine supplements are well established as energizing supplements in a wide range of sports. However, their use together in martial arts, especially karate, has been less investigated. Beta-alanine supplementation improves high-intensity exercise performance by increasing muscle carnosine content, thereby increasing the intracellular proton buffer. Caffeine is a central nervous system stimulant that increases alertness and decreases perceived exertion. Therefore, the aim of this study is the chronic use of beta-alanine supplement separately or together with caffeine supplement on the specific performance of professional karate practitioners.
Methodology: The current research is of a developmental type and its method is semi-experimental and double-blind with the aim of investigating the effect of 4 weeks of beta-alanine supplementation and placebo in parallel groups. 30 athletes trained in karate at the level of the country's league were randomly placed in three parallel groups and for 4 weeks they consumed 6.4 grams of beta-alanine supplement or placebo and 6 mg per kilogram of body weight. The specific performance of the athletes was measured using a progressive aerobic test for karate before and after four weeks of project implementation.
Results: There is a significant difference in the karate aerobic test in the beta-alanine supplement group (P=0.042) and beta-alanine + caffeine (P=0.032) in the pre-test compared to the post-test of the subjects. While there is no significant difference in the pre-test compared to the post-test in the placebo group (P=0.078) of subjects.
Conclusion: Taking beta-alanine and caffeine supplements can improve the physical performance of karate practitioners.
