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 ( T lim ) a range of fixed target intensities. 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 + taurine; TTE + placebo; 3MAOT + taurine; 3MAOT + placebo. Taurine was provided at 50 mg kg −1 , whilst the placebo was 3 mg kg −1 maltodextrin. CP was higher ( P < 0.05) in taurine (212 ± 36 W) than baseline (197 ± 40 W) and placebo (193 ± 35 W). Work end power was not affected by supplement ( P > 0.05), yet TTE 5% > CP increased ( P < 0.05) by 1.7 min after taurine (17.7 min) compared to placebo (16.0 min) and there were higher ( P < 0.001) estimated T lim across all work targets. Acute supplementation of 50 mg kg −1 of taurine improved CP and estimated performance at a range of severe work intensities. Oral taurine can be taken prior to exercise to enhance endurance performance.
