中文摘要：

临床研究表明,雌激素缺乏是导致绝经后妇女骨质疏松的一个危险因素。适宜运动可以增加体内雌激素的分泌,但剧烈运动、大强度训练可影响下丘脑-垂体-性腺轴,使体内雌激素水平降低,对骨代谢产生负面影响。当雌激素缺乏时,运动员骨细胞对负荷的适应性可能导致骨的转运和吸收加速,反之,对骨代谢的成骨作用刺激减弱。运动-雌激素-骨代谢三者间的密切相关性,提示科学保护竞技运动员,尤其是女性专职运动员、教练员骨组织健康的必要性与重要意义。

英文摘要：

Clinical research has shown that the lack of estrogen in postmenopausal women with osteoporosis is a leading risk factors.Appropriate exercises can increase the level of estrogen secretion,but vigorous exercises,high-intensity training can affect thehypothalamus-pituitary-gonadal axis,to reduce the level of estrogen in vivo,have a negative impact on bone metabolism.When estrogen,bone cells adaptability to load ransfer and absorption may lead to accelerated bone,contrary to the bone to stimulate the weakened bone metabolism Exericses-Estrogen-Bone＇s close relation suggests the need and significance of scientific protection to bone health of Athletes,in particular,full-time female athletes and coaches.
