中文摘要：

目的观察不同低氧浓度环境训练后大鼠血清睾酮（testosterone,T）、皮质酮（corticosterone,C）的浓度及T/C的变化,为确立适宜的低氧训练模式提供实验依据。方法 SD大鼠60只,随机分为安静对照组（C）、常氧运动组（E）、15%氧浓度对照组（15C）、15%氧浓度运动组（15E）、11%氧浓度对照组（11C）和11%氧浓度运动组（11E）,每组10只,运动方式为跑台运动。采用ELISA方法检测大鼠血清中T和C的浓度。结果 （1）11C组T浓度低于C组（P〈0.05）;11E组T浓度低于E组（P〈0.01）;（2）E组大鼠血清C浓度高于C组（P〈0.05）;11E组C浓度低于E组（P〈0.01）;15E组C浓度低于E组（P〈0.05）;（3）11C组T/C值低于C组（P〈0.05）。结论 11%氧浓度对T/C的平衡可能带来负面影响,但运动可一定程度代偿低氧带来的不利影响;15%氧浓度未对大鼠T/C的平衡产生影响。

英文摘要：

Objective To observe the changes of serum testosterone（T）,corticosterone（C）,and testosterone/corticosterone（T/C） values in SD rats trained under different hypoxic conditions,so as to provide an experimental evidence for correct hypoxia training.Methods A total of 60 SD rats（8-week-old） were randomly divided into 6 groups： normal control（C）,normal exercise（E）,15% oxygen control（15C）,15% oxygen exercise（15E）,11% oxygen control（11C）,and 11% oxygen exercise（11E） groups.The animals received treadmill running for exercise,and the levels of serum T and C were examined by ELISA.Results（1） Testosterone level in group 11C was significantly lower than that in group C（P0.05）;testosterone level in group 11E was significantly lower than that in group E（P0.01）.（2） Corticosterone level in group E was significantly higher than that in group C（P0.05）;corticosterone levels in group 11E and 15E were significantly lower than that in group E（P0.05）.（3） The ratio of T/C in group 11C was significantly lower than that in group C（P0.05）.Conclusion The 11% oxygen may cause negative effects on the T/C balance,but exercise may compensate the negative effect to some extent;the 15% oxygen causes no noticeable influence to T/C balance.
