运动对去卵巢大鼠的影响

目的:研究不同强度运动对去卵巢大鼠骨量以外的其它因素的影响.方法:以三月龄SD 大鼠去卵巢作为绝经妇女模型,采取不同强度跑台运动( 中等强度和大强度运动) 与正常对照组和去卵巢对照组进行比较,测定各组大鼠的体重、摄食量、小腿三头肌重量和体积、股骨长度和宽度,以了解不同强度运动对去卵巢大鼠的影响.结果:去卵巢大鼠体重明显增加,以中等强度组大鼠的增加最显著,各组大鼠体重的增加并不伴随摄食量的增加.中等强度和大强度的跑台运动均可增加肌肉重量,有利于股骨的长长,而大强度运动不能增加肌肉的体积,对股骨的长长无作用.两种强度的运动对去卵巢大鼠股骨的增宽均无作用.结论:中等强度运动对去卵巢大鼠产生积极性作用,大强度运动对去卵巢大鼠无明显作用.

Effect of exercise on ovariectomized rats

The effect of two speed treadmill running(moderate intensity : 20m/min, 60min/day, 5days/week , Run1 and high intensity : 30m/min,60min/day,5days/week, Run2) on body weight, muscle weight and volume of triceps surae, length and width of femoral shaft was investigated in 3 months old ovariectomized (OVX) rats compared with sedentary OVX and sedentary sham-operated rats. The results showed that weight gain were higher in three OVX groups especially in Run1 group. Comparing the OVX group, two training groups had significant effects on the muscle weight , but Run1 training had significant effects on the muscle volume. Comparing the sham-operated group, two training groups had no significant effects on the femoral shaft width, but EX-1 training had significant effects on the length. In conclusion that the moderate intensity treadmill running had active effect on ovariectomized rats and the high intensity running had no significant effects.
