SCJ 45.2 Effect of Taurine Supplement on Aerobic and Anaerobic Outcomes: Meta-Analysis of Randomized Controlled Trials

Quiz CATD 0.2

Taurine is a well-known free amino acid that has gained prominence in recent years despite its little or no role in protein formation. Few studies on the ergogenic effect of taurine exist with inconsistent results. The answer to the question of whether performance markers demonstrate the benefit of taurine remains unclear. This study aimed to reach a consensus about whether taurine supplementation is effective on aerobic (time to exhaustion [TTE], maximal oxygen uptake [V̇O2max], and rating of perceived exertion) and anaerobic (power outputs, fatigue index, jumping, and blood lactate level) performance outputs. Google Scholar, PubMed databases, clinical trial websites, and gray literature were reviewed until November 2021. Mean differences (MDs) were pooled using random or fixed-effects models according to the heterogeneity degree of the related output. Although 18 studies were detected for the meta-analysis between 2001 and 2021, 16 studies were grouped. Only randomized controlled trials (single or double-blind) were considered. Taurine supplementation had a significant effect on vertical (MD 5 3.60; 95% confidence interval [CI] [2.32 to 4.89], p , 0.00001) and countermovement (MD 5 8.50; 95% CI [4.78 to 12.22], p , 0.00001) jump performance when compared with a placebo group. Taurine supplementation had no significant effect on the V̇O2max level and rate of perceived exertion (respectively, MD 5 20.54 mL/kg/min; 95% CI [26.84 to 5.75], p 5 0.87; MD 5 20.24; 95% CI [20.74 to 0.27], p 5 0.35) when compared with a placebo group. Overall, it looks to be effective for jumping performance and TTE. Taurine supplementation may be useful for people who want to improve these performance outputs.
