Effects of victory and defeat on testosterone and cortisol response to competition: evidence for same response patterns in men and women.

In this study, we report evidence from sport competition that is consistent with the biosocial model of status and dominance. Results show that testosterone levels rise and drop following victory and defeat in badminton players of both sexes, although at lower circulating levels in women. After losing the match, peak cortisol levels are observed in both sexes and correlational analyses indicate that defeat leads to rises in cortisol as well as to drops in testosterone, the percent change in hormone levels being almost identical in both sexes. In conclusion, results show the same pattern of hormonal responses to victory and defeat in men and women.
