The purpose of this study was to investigate the acute effect of low,moderate, or high doses of taurine on anaerobic and physiologicalperformance in female rugby players. A total of 16 sub-elite femalerugby athletes (21.3 ± 1.5 yr, 168.0 ± 4.9 cm, 62.1 ± 3.5 kg mean ±SD) participated in this research. Following familiarization, partici-pants attended 4 successive tests separated by 72 h in a rando-mized, counter-balanced, crossover research design. Following anover night fast, participants completed a 5-min 60 Watt warm-upfollowed by a 30-s Wingate anaerobic test on a cycle ergometerafter ingestion of either 2 g taurine (LOWTAU), 4 g (MODTAU), 6 g(HIGHTAU) or placebo (PLA) 1 h before the test. Peak (PP) and meanpower (MP) along with heart rate (HR), rating of perceived exertion(RPE), capillary lactate and blood glucose were measured. LOWTAUdid not affect PP, MP, HR, lactate and glucose compared to PLA (p >0.05), while MODTAU improved MP and HIGHTAU improved PP andMP compared to PLA and LOWTAU (p < 0.05). MODTAU andHIGHTAU had little effect on HR, blood lactate and glucose (p >0.05). A single dose of taurine (MODTAU or HIGHTAU) 1 h prior tocompetition or training would provide an ergogenic effect on sub-sequent power output.ARTICLE HISTORYReceived 17 August 2022Accepted 21 March 2023KEYWORDSAnaerobic power; doseresponse; female athlete;rugby; supplementIntroductionDietary supplements, such as energy drinks, often consist of different ingredients that arethought to increase athletic performance (Astorino et al., 2009; Stellingwerff & Cox, 2014).However, the combination of various performance-enhancing stimulants and substancesin energy drinks makes it difficult to understand the real effects of some of them onathletes’ performance (Milioni et al., 2016). An example, taurine, a sulphur-containingnon-essential amino acid, is one of the main ingredients in many popular energy drinks(Warnock et al., 2017) and regulates intracellular Ca2+ utilization in skeletal muscle fibresCONTACT Zoran Milanović zoooro_85@yahoo.com Faculty of Sport and Physical Education, University of Niš,Čarnojevićeva 10a, Niš 18000, SerbiaRESEARCH IN SPORTS MEDICINE2024, VOL. 32, NO. 4, 621–630https://doi.org/10.1080/15438627.2023.2198129© 2023 Informa UK Limited, trading as Taylor & Francis Group
