Abstract
Aim: Recently, energy drink consumption by athletes has become increasingly popular. Athletes believe that energy drinks can be used to enhance their performance during training and competition due to their potentially ergogenic ingredients such as carbohydrates, caffeine, sodium and taurine, among others. Therefore, the purpose of this study was to determine the effectiveness of the acute ingestion of a taurine and caffeine-containing drink on Wingate cycle performance and blood lactate levels in active men.
Method: A sample of 19 active male students (age: 8/0±3/22years, height7/6±2/71: cm, weight: 4/5±9/175kg) from Mazandaran University were selected. This research was conducted on two separate sessions with four days rest in between. In the first session, all of the subjects participated in the Wingate test, after having a standard breakfast, and after the blood taking (before and 2 min after test) and hand muscle esterangth measurement. In the second session, subjects were randomly divided in three groups (taurine and caffeine-containing drink, placebo and no drink groups). Immediately after having breakfast (forty minutes prior to test beginning), each group received 6 ml/kg.bw of related beverages.
Results: In the taurine and caffeine-containing drink group, minimum (p=0/017) and mean (p=0/029) power was increased and blood lactate before (p=0/357) and after (p=0/920) the test, was unchanged
Conlusion: In conclusion a commercially-available taurine and caffeine-containing drink (Red Bull) enhances anaerobic power of active male.
