不同运动量训练对大鼠血睾酮及相关指标的影响

The effect of different exercise loads on rats' serum testosterone and correlative indexes

为探讨运动量与血睾酮及相关指标的关系 ,对大鼠进行小运动量和大运动量两种训练 ,观察不同运动量对大鼠血清总睾酮 (TT)、游离睾酮 (FT)和皮质酮 (C)浓度的影响。结果显示 :小运动量组大鼠血清TT、FT和C均未出现明显下降 ;大运动量组大鼠血清TT、FT和C均出现显著性降低 ,并且TT/C值下降幅度达40 2 2 %。因此认为 ,过度训练引起运动性低血睾酮 ,适度的运动量训练可以避免低血睾酮 ;血清游离睾酮的极度低下是引起低血睾酮的直接因素 ;血清皮质酮浓度降低反映机体应激能力低下 ;

Rats were trained in different exercise loads in order to study the relationship between exercise loads and serum testosterone and correlative indexes.The concentrations of serum total testosterone,free testosterone and corticosterone were observed.results showed that the serum TT,FT and C of the low exercise load rats were not lowered statistically,while that of the heavy exercise rats decreased remarkably and their TT/C dropped by 40.22%.The results suggest that:1)excessive training causes low serum testosterone,but proper exercise can keep serum testosterone from reducing;2)the extreme decreasing of FT is a direct factor of low serum testosterone;3)the decreasing of C reflects a lower stress ability;4)the rate of TT/C can be a reference to estimate the excessive training.
