Oral taurine improves critical power and severe-intensity exercise tolerance
Open accessAbstract
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.

High bioavailability of nitric oxide increases release of calcium, improving contractile function of skeletal muscle and helping recovery of phosphocreatine reserves, preventing depletion during repeated efforts and improving release and reuptake of calcium in the sarcoplasmic reticulum.
“The high bioavailability of nitric oxide increases release of calcium (Ca 2+ ) improving contractile function of the skeletal muscle [42] and helping recovery of phosphocreatine reserves, which prevents depletion during repeated efforts and improves release and reuptake of calcium in the sarcoplasmic reticulum [43, 44].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
