Abstract :The study aimed to investigate the effect of acutely consuming high-dose isolated 6 g of taurine 90 min before incremental treadmill-running time to exhaustion insert ignore into journalissuearticles values(TTE); performance on maximal oxygen uptake insert ignore into journalissuearticles values(VO2max);, maximal heart rate insert ignore into journalissuearticles values(HRmax);, TTE, and ratings of perceived exertion insert ignore into journalissuearticles values(RPE);. A total of ten well-trained, competitive male endurance insert ignore into journalissuearticles values(biathlon); athletes participated in this study. A double-blind, randomized crossover design was used in the study and consisted of three separate testing sessions. During the second and third sessions, 90 min before the exercise protocols, participants consumed ~500 ml of a sugar-free lemonade drink with either 6 g of taurine or nothing added insert ignore into journalissuearticles values(placebo);. The incremental treadmill-running TTE performance started at 6km·h-1, and the participants warmed up for 6 minutes at this constant speed. After a warm-up, the treadmill\`s speed was increased by 0.016km/h per second, and the slope of the treadmill was increased by 0.5% for each 60 seconds. Oxygen uptake insert ignore into journalissuearticles values(VO2); and HR were measured while the participant was running on the treadmill. RPE was measured immediately after each trial using the Borg Scale insert ignore into journalissuearticles values(6-20 points);. As a result, the acute ingestion of 6 g of taurine 90 min before incremental treadmill-running TTE performance did not enhance TTE, HRmax, and RPE but did result in a non-significant slight change in VO2max insert ignore into journalissuearticles values(2%);.
