“…A physiological dose of dietary taurine combined with caffeine significantly increased muscle power output and time to fatigue, but there was no difference compared to the effect of caffeine alone, suggesting that larger amounts of taurine are needed to derive a significant ergogenic benefit. The combination of taurine and fish oil improved the GLUT4 distribution in the plasma membrane of muscle tissue, reduced serum free fatty acids, and increased the activity of acyl‐CoA oxidase (ACO), which is the rate‐limiting enzyme of peroxisomal β‐oxidation.…”

Energy metabolism is a basic and general process, by which the body acquires and uses energy to maintain normal function, and taurine plays a vital role in energy metabolism. Taurine deficiency may cause a weak energy metabolism and energy metabolism dysfunction. Taurine biosynthetic ability is limited, and its supplementation in the diet can strengthen energy metabolism in muscle performance, cardiac function, liver activity, and adipose tissue. Combining taurine with other drugs may have a superior effect in energy metabolism. In many metabolic disorders, taurine, or the combination of taurine with other drugs, also functions as a repair treatment for damaged tissues, and acts as a promoter for the balance of energy metabolism. The present study discusses the potential roles of taurine in energy metabolism.

“…the power that we predict would have been obtained at each time point if the muscle remained in standard Krebs solution). The difference between the recorded 'caffeine-treated' power and the predicted 'control' power was used to determine a treatment effect (James et al, 2005;Tallis et al, 2012Tallis et al, , 2014aTallis et al, , 2017c. Using this corrected data, a paired t-test was performed to assess difference in work loop power output between the pre-treatment control and post-treatment washout for each muscle.…”

This study aimed to examine the effects of exercise-induced increases in skeletal muscle contractile performance on isolated skeletal muscle caffeine sensitivity in mice. CD1 mice (n=28; 30 weeks old) either served as controls or underwent 8 weeks of voluntary wheel running. Following the treatment intervention, whole soleus (SOL) or a section of the costal diaphragm (DIA) was isolated from each mouse and tested to determine the effect of 70 µmol l −1 caffeine on work loop power output. Although caffeine elicited a significant increase in power of both the SOL and the DIA relative to levels in a non-caffeine-treated control, the effect was not different between the experimental groups, despite the muscles of the trained group producing significantly greater muscle power. There was no significant relationship between training volume or baseline work loop power and the caffeine response. These results indicate that an exercise-induced increase in muscle performance did not influence the performance-enhancing effects of caffeine.

“…To set the ecological validity of the experimental design, we selected a commercially available energy drink that contained caffeine, taurine, sodium bicarbonate, l -carnitine and maltodextrin, although these components were included in the same proportion in the placebo drink. Interestingly, with the exception of carbohydrates, there is a lack of evidence to substantiate claims that components of energy drinks, other than caffeine, contribute to the enhancement of physical ( 58 , 59 ) or cognitive performance ( 58 , 60 ) . Furthermore, the amount of carbohydrate provided with the beverages in the experimental trials (2 g) was not enough to produce the purported benefits obtained with carbohydrate ingestion during exercise.…”

The use of energy drinks in sport: perceived ergogenicity and side effects in male and female athletes

et al. 2014

The use of caffeine containing energy drinks has dramatically increased in the last few years, especially in the sport context because of its reported ergogenic effect. The ingestion of low to moderate doses of caffeinated energy drinks has been associated with adverse side effects such as insomnia or increased nervousness. The aim of the present study was to assess psycho-physiological changes and the prevalence of side effects resulting from the ingestion of 3 mg caffeine/kg body mass in the form of an energy drink. In a double-blind and placebo controlled experimental design, ninety experienced and low-caffeine-consuming athletes (fifty-three male and thirty-seven female) in two different sessions were provided with an energy drink that contained 3 mg/kg of caffeine or the same decaffeinated energy drink (placebo; 0 mg/kg). At 60 min after the ingestion of the energy drink, participants completed a training session. The effects of ingestion of these beverages on psycho-physiological variables during exercise and the rate of adverse side effects were measured using questionnaires. The caffeinated energy drink increased self-perceived muscle power during exercise compared with the placebo beverage (6·41 (SD 1·7) v. 5·66 (SD 1·51); P¼ 0·001). Moreover, the energy drink produced a higher prevalence of side effects such as insomnia (31·2 v. 10·4 %; P,0·001), nervousness (13·2 v. 0 %; P¼0·002) and activeness (16·9 v. 3·9 %; P¼ 0·007) than the placebo energy drink. There were no sex differences in the incidence of side effects (P. 0·05). The ingestion of an energy drink with 3 mg/kg of caffeine increased the prevalence of side effects. The presence of these side effects was similar between male and female participants.
