研究人员对 20 名优秀女子手球或排球运动员进行了为期 4 个月的训练后唾液中皮质醇、雄烯二酮和脱氢表雄酮的反应评估。在训练计划开始时 (W-1) 以及第 7 周 (W-7) 和第 16 周 (W-16)。在醒来时（上午 8 点；静息样本）以及下午 6 点进行的 2 小时锻炼（模拟比赛）之前 (t(o)) 和结束时 (t(120)) 测量激素浓度。训练计划增加了两组受试者静息唾液中肾上腺雄激素的浓度（P < 0.05），而皮质醇浓度没有变化。相比之下，排球运动员中，训练量增加所产生的压力刺激并不影响运动过程中的肾上腺皮质代谢。事实上，模拟排球比赛导致唾液皮质醇（P < 0.05）和雄激素浓度（P < 0.05）下降，而不考虑测试调查选择的周数。相比之下，模拟手球比赛仅在 WI 时导致皮质醇浓度增加（P < 0.05），而在训练计划的任何一周内，肾上腺雄激素浓度都没有变化。在运动期间和训练计划过程中，这些激素的调节剂似乎是不同的。
In a group of 20 elite female handball or volleyball players, an evaluation was made of the response to a 4-month training period of cortisol, androstenedione and dehydroepiandrosterone in the saliva. At the beginning of the training programme (W-1) and at the 7th (W-7) and 16th weeks (W-16). hormone concentrations were measured on awakening (8 a.m.; resting samples), and also before (t(o)) and at the end (t(120)) of a 2-h exercise session (simulated match) which took place at 6 p.m. The training programme increased the concentrations of adrenal androgens in the saliva at rest (P < 0.05) for both groups of subjects, with no change being noted in cortisol concentrations. In contrast, amongst the volleyball players, stressful stimuli produced by an increase in the amount of training did not affect adrenocortical metabolism during exercise. Indeed, a simulated volleyball match resulted in a decrease in salivary cortisol (P < 0.05) and androgen concentrations (P < 0.05) without regard for the week chosen for the test investigations. In contrast, a simulated handball match caused an increase in cortisol concentrations at WI only (P < 0.05), with no change in the adrenal androgens concentration in any week of the training programme. The regulators of these hormones during a period of exercise and during the course of a training programme would seem to be different.
