Recent research suggests that cortisol (C) level moderates testosterone (T) reactivity to the Trier Social Stress Test (TSST) in men. The extent to which C moderates T reactivity in other circumstances and in women is not known. In this retrospective study, before- and after-competition salivary levels of C and T from 97 intercollegiate women athletes competing in one of four different sports (soccer, volleyball, softball, tennis) were used to evaluate the influence of before-competition C level on T reactivity in women's athletic competition. Athletic competition was associated with a substantial increase in salivary levels of C and Tin the vast majority of athletes. Before-competition level of C significantly moderated testosterone reactivity to athletic competition - women with relatively low levels of C showed larger increases in T to competition than women with higher levels of C. Clearly, the moderating effect of C on T reactivity is not limited to laboratory settings intended to increase social stress, but is also seen in (as we show here) the context of athletic competition.
