Randomized Controlled TrialSexual dimorphism in exercise-induced response on steroid hormones to a 24-week supervised concurrent training intervention.
Steroid hormones are key mediators of adaptative responses to exercise, a stimulus that may concurrently affect their blood concentrations. However, the chronic endocrine adaptations and whether these potential changes are dependent on exercise intensity remain undetermined. Moreover, it is also unknown if the exercise-induced effects on steroid hormonal status are related to the participant' sex. ⋯ Our 24-week supervised concurrent training intervention showed no significant changes in steroid hormone levels. However, a significant decrement of T/C ratio was observed only in women, indicating a sexual dimorphism in the effect on T/C ratio.
