Abstract

This study investigated the effects of acute oral taurine ingestion on: (1) the power–time relationship using the 3-min all-out test (3MAOT); (2) time to exhaustion (TTE) 5% > critical power (CP) and (3) the estimated time to complete (Tlim) a range of fixed target intensities. Twelve males compl...

Twelve males completed a baseline 3MAOT test on a cycle ergometer. Following this, a double-blind, randomised cross-over design was followed, where participants were allocated to one of four conditions, separated by 72 h: TTE&#x2009;+&#x2009;taurine; TTE&#x2009;+&#x2009;placebo; 3MAOT&#x2009;+&#x2009;taurine; 3MAOT&#x2009;+&#x2009;placebo. Taurine was provided at 50 mg kg&#x2212;1, whilst the placebo was 3 mg kg&#x2212;1 maltodextrin. CP was higher (P&#x2009;&lt;&#x2009;0.05) in taurine (212&#x2009;&#xB1;&#x2009;36 W) than baseline (197&#x2009;&#xB1;&#x2009;40 W) and placebo (193&#x2009;&#xB1;&#x2009;35 W).

Acute supplementation of 50 mg kg&#x2212;1 of taurine improved CP and estimated performance at a range of severe work intensities.
