Although endocrine effects of physical or psychological stress are well documented, it is not known to what extent adaptation to prolonged exertion occurs. We therefore investigated the impact of an 1100 km run of 20 days' duration on selected pituitary, testicular, adrenal and thyroid hormones. Blood samples were obtained from five male athletes prior to and after the day's run on the 1st, 5th, 9th, 14th and 19th day. Results show that adrenal and thyroid function soon adapt to the daily strain. Testosterone levels, however, were markedly decreased throughout the 20 days while LH levels remained unchanged. Thus it appears that the reproductive endocrine system is more susceptible to long-term stress effects than the more vital functions of the thyroid and adrenal glands.
虽然身体或心理压力的内分泌影响已有充分记录，但对于长期运动的适应程度尚不清楚。因此，我们研究了持续20天的1100公里跑步对选定的垂体、睾丸、肾上腺和甲状腺激素的影响。在第1、5、9、14和19天跑步当天前后，从五名男性运动员身上采集血样。结果表明，肾上腺和甲状腺功能很快适应了日常压力。然而，睾酮水平在整个20天内显著下降，而促黄体生成素水平保持不变。因此，生殖内分泌系统似乎比甲状腺和肾上腺等更重要的功能更容易受到长期压力的影响。
