When it is hot, athletes perform better with taurine
When the mercury in the thermometers rises eerily high, athletes perform better if they take 4 grams of taurine 2 hours before their training or competition. British researchers at St Mary's University write about this in the European Journal of Sport Science. Taurine enhances the body's ability to keep its temperature low.
On two different occasions, the researchers got 11 male students to cycle at a challenging speed until they were unable to maintain this pace. This happened in a room with a temperature of 35 degrees Celsius and a relative humidity of 40 percent.
On one occasion the test subjects took placebo capsules 2 hours before the test, and the other on capsules containing taurine.
The researchers gave the subjects 50 milligrams of taurine per kilogram of body weight. If you weigh ninety kilos, that means 4.5 grams. That is more than is in energy drinks. A 250 milliliter can of energy drink usually contains one gram of taurine.
The researchers made their taurine capsules themselves. They bought the taurine from MyProtein. [myprotein.com]
Taurine supplementation ensured that the subjects continued their exercise trial about 10 percent longer than was possible with a placebo.
The above shows how taurine improved performance. Taurine limited the rise in body temperature. This was because taurine stimulated the production of sweat. In physiological jargon: taurine has a sudomotor effect.

In physiological jargon: taurine has a sudomotor effect. And because of this sudomotor effect, the athletes experienced the trial as less exhausting.
"This is the first study to examine the effect oral taurine ingestion on thermoregulation during cycling in the heat", the researchers write. "Therefore, this study also provides the first evidence of taurine's role in thermoregulatory processes. Notably, the profound influence of taurine on sudomotor function was an important finding of the current study and indicates a potential central mechanism, as previously described in animal models."
"Based on our findings, a single dose of taurine 2 hours prior to training or competition would provide an ergogenic and thermoregulatory effect."
"Given that this is the first study to report on this topic, future research should attempt to corroborate our findings across different populations and investigate the potential explanatory mechanisms."
