Resumo


The Taekwondo (TKD) is a martial art of high intensity with rapid and repeated blows that require a rapid energy demand. Supplementation of vitamin B6 can be used aiding the release of glucose and its acute effects on fighters are still scarce. The aim of this study was to investigate the effect of supplementation with vitamin B6 in the performance of athletes during the Taekwondo kicks Bandal Tchagui protocol. The study included five Taekwondo athletes, and they received vitamin B6 or placebo. After 30 minutes, these athletes passed by a protocol of kicks Bandal Tchagui comprising two rounds with 1 minute. We analyzed the amount of kicks, minute ventilation, blood glucose levels and cardiovascular responses. Results are expressed as mean and standard deviation. We used the Student t test for independent samples, considering a significant difference when p<0.05. There was an increase of chutes (15 kicks, 6%) in the minute ventilation (9.6 ml/kg/min, 9%) and blood glucose (16 mg/dL, 15%) supplemented with the situation vitamin B6. The data from this study suggest that vitamin B6 might be assisting in both the performance of athletes of TKD and the availability of glucose for energy compensation for the year, and thus aid in performance.
