Effect of Acute Supplementation (taurine) on Maximal Strength and Anaerobic Power

March 13, 2025 updated by: Kyriaki Antoniou, University of Central Lancashire Cyprus
This crossover-design study examines the acute effect of taurine on trained individuals aged 18-40 on strength and power outputs.

Detailed Description

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Taurine supplementation
Participants consumed 50mg·kg -1 of taurine diluted in 500ml of a sugar-free lemonade drink.
Dietary supplement: Taurine supplementation
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 Comparator: Placebo
Placebo was a 500ml sugar-free lemonade drink with nothing added
Dietary supplement: Placebo
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.
