摘要
甲状腺功能紊乱主要影响机体运动的耐受性,从而导致机体剧烈运动能力的降低。另一方面,运动本身也可直接或间接影响甲状腺功能,或者引起下丘脑-垂体-甲状腺轴功能的急剧改变,或者导致运动员甲状腺功能的长期改变。运动员甲状腺功能的改变是一种耐受能力的适应性机制,这种适应性机制可使能量的摄取和消耗趋于平衡。女运动员过度减重常常出现"低T3综合症",从而导致运动性闭经以及其它下丘脑-垂体-甲状腺轴功能的紊乱。
Thyroid dysfunction affects exercise tolerance and results in reduced performance of strenuous activities. On the other hand, exercise itself may have direct or indirect effects on the function of thyroid, or cause acute changes in the function of the pituitary-thyroid axis, or cause the lasting changes of athlete＇s thyroid function. The changes of athlete＇s thyroid function might be viewed as an adaptive mechanism associated with tolerance ability. This mechanism provides better balance between energy intake and consumption. The excessive weight loss of the female athletes may induce a ＂Low T3 Syndrome＂ accompanied by amenorrhea as well as other alterations of pituitary function.
