Researchers found that the winners in wrestling competitions have an all-time high level of testosterone compared to losers, reports The Times of India.

This discovery is directly related to research focused on the correlation of changes in testosterone levels depending on aggressive or competitive behavior in males. In this connection, a theory is being put forward concerning the "social superiority" caused by hormones, which contributes to the future success.

Experts collected samples of blood before and after the competition among members of the university team of wrestlers. Scientists turned their attention to testosterone and other hormones, including cortisol and adrenaline, in winners and losers. So, all the hormones, except for testosterone, did not differ significantly from the winners and losers. Meanwhile, changes in adrenaline levels were strongly associated with changes in testosterone levels in winners, but not in losers.

Commented the author of the study Emdryu S. Fry of the University of Kansas: "The findings suggest that the winning wrestlers compared to the losers can use some unique mechanism of response to testosterone. By the way, previous studies have shown that such differences can be detected not only among athletes, athletes, but also in chess players. This suggests that a high level of testosterone may in principle be related to the issue of "survival".
