To evaluate the effect of variations in physical activity on selected hormone concentrations in male versus female athletes, fasting serum concentrations of cortisol (C), total-testosterone, free-testosterone, non sex hormone binding globulin (SHBG) bound testosterone, dehydroepiandrosterone, 4-androstene-3,17-dione and SHBG were studied. The tests were performed in nine male and seven female elite endurance athletes during the off-season (test 1), early in the competition season (test 2) and at the end of the competition season (test 3). The C concentration increased significantly during the competition season in women but not in men. Further, the mean C concentrations at test 3 as well as the mean level during the whole observation period (tests 1, 2, 3) were significantly higher in women than in men. No significant changes were found in androgen concentrations or androgen:cortisol ratios within the two groups. The differences between the sexes in C response may indicate different adaptive mechanisms to similar physical stress.
为评估体力活动变化对男性和女性运动员特定激素浓度的影响，研究了空腹血清中皮质醇（C）、总睾酮、游离睾酮、非性激素结合球蛋白（SHBG）结合睾酮、脱氢表雄酮、4-雄烯-3,17-二酮和SHBG的浓度。对9名男性和7名女性优秀耐力运动员在休赛期（测试1）、比赛季初期（测试2）和比赛季末期（测试3）进行了检测。女性在比赛季期间C浓度显著升高，而男性未出现此情况。此外，测试3时的平均C浓度以及整个观察期（测试1、2、3）内的平均水平，女性均显著高于男性。两组内雄激素浓度或雄激素与皮质醇的比值均未发现显著变化。两性在C反应上的差异可能表明对相似身体应激的不同适应性机制。
