Changes in plasma cortisol, androstenedione, testosterone and luteinizing hormone (LH) were measured in five young male sprinters after maximal short-term running and in five young male long-distance runners after moderate (90 min, 4.3 min/km) and intense (45 min, 3.3 min/km) long-term running. Short-term running increased mean plasma cortisol (27%) and androstenedione (19%) significantly; no appreciable changes were found in mean plasma testosterone or LH levels. Intense long-term running caused considerable increases in mean plasma cortisol (43%) and androstenedione (53%). Immediately after the long-term runs mean plasma testosterone and LH did not show nay significant changes, but half an hour later mean plasma LH was found to have dropped significantly below the preceding level, by 42% after the moderate run and by 45% after the intense run. At this time the intense long-term run caused a significant decrease in mean plasma testosterone, which remained depressed up to 3 h after the end of the exercise. This study implies that the changes in plasma hormone levels depend more on the intensity of the exercise than on its duration. The activity of the pituitary-adrenocortical system appears to be a good indicator of the effort expended during the exercise. In the pituitary-testicular system, in contrast, the effort expended may be more accurately reflected by changes during the recovery period.
对5名年轻男性短跑运动员进行最大强度短期跑步后，以及对5名年轻男性长跑运动员进行中等强度（90分钟，4.3分钟/公里）和高强度（45分钟，3.3分钟/公里）长期跑步后，测量了他们血浆皮质醇、雄烯二酮、睾酮和促黄体生成素（LH）的变化。短期跑步使血浆皮质醇均值显著增加（27%），雄烯二酮均值显著增加（19%）；血浆睾酮或LH水平均值未发现明显变化。高强度长期跑步导致血浆皮质醇均值大幅增加（43%），雄烯二酮均值大幅增加（53%）。长期跑步结束后即刻，血浆睾酮和LH均值未显示出任何显著变化，但半小时后发现血浆LH均值显著低于之前水平，中等强度跑步后降低了42%，高强度跑步后降低了45%。此时，高强度长期跑步导致血浆睾酮均值显著下降，直至运动结束后3小时仍处于较低水平。这项研究表明，血浆激素水平的变化更多地取决于运动强度而非运动持续时间。垂体 - 肾上腺皮质系统的活动似乎是运动中所消耗努力的一个良好指标。相比之下，在垂体 - 睾丸系统中，运动中所消耗的努力可能在恢复期的变化中得到更准确的反映。
