应用“ＧｎＲＨ类似物（Ｇ－Ａ）运动试验”观察女子运动员高强度训练后下丘脑的变化及其对垂体－性腺轴的影响。９名处于排卵后期的运动员参加了为期５天的试验。对照组（４名）极限负荷运动后ＬＨ、ＦＳＨ等无明显变化而Ｅ２和Ｅ２／Ｐ降低。Ｇ－Ａ组ＬＨ和ＦＳＨ剧烈增高，Ｅ２和Ｅ２／Ｐ明显升高而ＦｓＨ／ＬＨ降低，提示高强度运动主要抑制下丘脑而不是垂体和外周性腺。但在５天实验中未见这一现象的累积现象。Ｔ，Ｃ，ＡＣＴＨ和Ｔ／Ｃ均未见有规律的变化，提示以Ｔ／Ｃ比率改变评价女子运动员机能状态可能是不敏感的。
Applying “GnRH Analogue (G-A) Exercise Test” to observe the change of hypothalamus and its effect on pituitary-gonadal axis after high intensity training in female athletes. Nine late-ovulation athletes participated in a five-day trial. In the control group (4), LH and FSH did not change significantly but E2 and E2 / P decreased after the limit load exercise. LH and FSH increased significantly in G-A group, E2 and E2 / P increased significantly and FsH / LH decreased, suggesting that high-intensity exercise mainly inhibits the hypothalamus but not the pituitary gland and peripheral gonad. However, this phenomenon did not accumulate in the 5-day experiment. There was no regular change in T, C, ACTH and T / C, suggesting that changing the T / C ratio may not be sensitive to evaluating the performance of female athletes.
