American scientists found out that the levels of the sex hormone in men increase with 30 % right after the end of a soccer match. Even hour after the game the levels of testosterone remain 15 % higher than the normal.
The amount of testosterone increases mostly in football players, who play in front positions, no matter their age, shows the research. Scientists have studied farmers from the far tribe area Tsimane in Bolivia, because men there usually have higher levels of testosterone. Native men keep stabile amount of the sex hormone during their whole life and they are not prone to gaining weight, heart diseases and other sicknesses related to aging.
Increasing the testosterone after a game of soccer is observed also in men, living in USA and other industrialized countries. Keeping high levels of testosterone damages the immune system. The discovery explains partly why so many famous footballers are involved in sex scandals.
The team of researchers organized a football tournament for eight teams from the Bolivian area. Increasing the levels of testosterone shows that increasing the hormone as a result of a game is a main aspect of human biology, which continues to exist, even if it increases also the danger from sickness or infection.
