运动性血睾酮降低过程中大鼠组织形态变化的观察

在大鼠以5%体重的负重的进行间歇游泳训练五周(TA组)(游泳5 min-休息1分钟,6组/日,6次/周)后,停训一周(TC组),继续训练一周:负荷不变(TD组)、负荷量加倍(5%体重的负重,2组/日,TE组)或强度增加(6%体重的负重,1组/日,TF组),观察各组大鼠心、肝、肾等脏器组织形态学的变化,并与同龄血睾酮正常的不训练大鼠(Sc组)或以5%体重的负重的进行间歇游泳训练一周大鼠(TG组)进行比较.结果显示随着训练时间、训练负荷和训练强度的增加,大鼠血睾酮降低的程度加剧,伴随有重要脏器的病理性变化的运动性血睾酮降低,应属病理性的变化.

The viscera histomorphologic changes of the rats following the decrease of serum testoserone

After the five-week intermittent anaerobic swimming training(exercising 5 minutes with a rest of 1 minute,6 groups per day and 6 times a week) for 5 weeks with a load equivalent to 5% of their body weight.(TA group),a group of the rats(TC group) stopped training for one week,while the other groups were forced to continue training.The TD group trained with the same load.The load of the TE group was doubled,that is bearing a weight of 5% of their body weight and the rats trained 2 times per day.The intensity of the TF group was increased and the rats trained once a day with the load of 6% of their body weight.The histomorphologic changes of the heart,liver,and kidney of each group rats were observed.By comparing with the sedentary rats of the same age(Sc group) or those of the rats trained once a day with the load of 5% of their body weight for one week(TG group),it was found that the decrease of serum testosterone due to exercise accompanying with pathological changes in some organs belongs to pathological character.
