已知很多因素可干扰正常人的月经周期。近来有人指出,剧烈运动对于升高卵巢激素在血液中的浓度是一强有力的刺激,可使血中孕酮水平升高,而且变化的大小明显地受训练强度的影响。剧烈运动也能显著地缩短黄体期,而缩短的程度与总代谢能量的消耗也成比例。亦有人认为,参加运动可减轻痛经。由于月经周期受黄体生成素(LH)、促卵泡素(FSH)、雌二醇(E_2)、孕酮(P)和催乳素(HPr)之间复杂的相互关系的调节,因此运动引起的月经改变可能伴有一种或多种上述激素的异常。本文对三组妇女在一个完整的月经周期内每人每天采血连续测定血中LH、FSH、E_2、P 和HPr 的浓度。实验组为15～19岁的四位游泳运动
Many factors are known to interfere with the normal menstrual cycle. Recently, it has been pointed out that strenuous exercise is a powerful stimulus for raising the concentration of ovarian hormones in the blood, which can increase the level of progesterone in the blood, and the magnitude of the change is obviously affected by the training intensity. Strenuous exercise can also significantly shorten the luteal phase, and the degree of shortening is proportional to the total metabolic energy expenditure. Some people think that participating in sports can reduce dysmenorrhea. Because the menstrual cycle is regulated by the complex interrelationships between the soma LH, FSH, E2, progesterone (P) and prolactin (HPr), it is possible that exercise-induced menstrual changes may Abnormalities associated with one or more of these hormones. In this paper, three groups of women in a complete menstrual cycle per person daily blood samples for continuous determination of LH, FSH, E_2, P and HPr concentration. Experimental group of 15 to 19-year-old four swimming
