Endogenous testosterone and competition: the effect of "fasting".
Salivary testosterone was measured among male college wrestlers (n = 12), some of whom fasted before their matches while others did not. Nonfasting wrestlers had increasing testosterone on the day of their match, whereas fasting wrestlers had decreasing testosterone. Apparently, fasting perturbs the normal pattern of testosterone fluctuation associated with competition. As used here, the term "fasting" does not necessarily imply 100% abstinence from nourishment.
