About this study

The purpose of this study is to further investigate any potential ergogenic effects offered by taurine, under specific conditions, namely that of acute supplementation, as opposed to the chronic supplementation protocols of many popular ergogenic aids, such as creatine and beta alanine. Exercise modes investigated include maximal isometric strength, maximal instantaneous power generation, and sustained maximal anaerobic power output, investigated via grip strength, vertical jump height, and the Wingate test, respectively.

Treatment and study plan

Taurine supplementation

Dietary Supplement

For the intervention trials participants consumed the following in randomized order: 50mg·kg -1 of taurine diluted in 500ml of a sugar-free lemonade drink or placebo which was a sugar-free lemonade drink with nothing added, 60 minutes before the exercise protocols. Participants wore a nose plug during consumption to confirm that no taste differences were discernible between trials.

Placebo

Dietary Supplement

Participants wore a nose plug during consumption to confirm that no taste differences were discernible between trials.
