运动与糖皮质激素

Exercise and Glucocorticoid

综述了有关运动与糖皮质激素的研究进展，１．运动与高原训练可引起血中糖皮质激素水平显著升高，并与运动强度有很大关系，而与运动总量和持续时间相关性较小；２．过量糖皮质激素可导致肌肉萎缩，对其发生的机制有新的认识，而运动能否有效预防和治疗该性质的肌肉萎缩，尚有争议；３．有关运动引起糖皮演激素分泌水平改变对机体免疫的影响及其机制。

his article reviewed some literattires about the studying progrese of exercise and glucocorticoid(GC)in a few aspects.First,blood GC significantly increased after exercise and altitude training.Somereports indicated that not the volume and duration but exercise intersity was the dominant factor whichinduced high blood GC level.Second,the high level of GC may induce muscle atrophy, but it was equivocal wheather exercise is capble of preventing and treating excess GC-induced muscle atrophy.Third,changes of GC execreation can suppress human immunity, howeve ,the action mechhanism of this hormone has not been fully established.
