The aim of this study was to examine the effect of supra-maximal exercise on circulating concentrations of salivary testosterone, salivary cortisol, and salivary immunoglobulin A in female adolescents. Nineteen apparently healthy females aged 15–16 years participated in this study. All participants completed 6 × 8 s sprints, interspersed with 30 s recovery intervals on a cycle ergometer. Salivary testosterone, cortisol, and immunoglobulin A samples were taken before and 5 min after exercise. Experimental procedures continued over two mornings, at least 3 h after a light breakfast. Participants refrained from performing any strenuous physical activity for at least 24 h prior to the exercise test. None of the participants were engaged in a structured training programme. The group mean ( ± s) for peak power output was 562 ± 113.0 W. Female adolescents recruited for this study showed no changes in salivary testosterone, cortisol or immunoglobulin A following repeated bouts of supra-maximal cycling (P > 0.05). To date, there has been a paucity of information concerning adolescents' hormonal and mucosal immune function responses to supra-maximal exercise. Our data provide further guidance with regard to physical activities and sports prescription for female adolescents. Further research, on a larger sample of females, is required to elucidate the physiological significance of these findings.

AMPK inactivation in mononuclear cells: a potential intracellular mechanism for exercise-induced immunosuppression Moir, Hannah; Butcher, Lee; Jones, Ken; Hughes, Michael G.; Neale, Huw; Jia, Huidong; Al-Ismaily, Zuleikha; Webb, Richard (NRC Research Press, 2008)There is much evidence that prolonged intense exercise suppresses the immune system. However, the intracellular biochemical mechanisms linking exercise and immunosuppression remain obscure. The purpose of this study was ...
