游泳对小鼠肠动力功能的影响

Effect of swimming on the intestinal propulsive function in rats

目的:观察游泳对小鼠小肠推进运动的影响。方法:以昆明种小鼠为实验动物,随机分为2组:对照组,实验组;以小肠推进百分比为指标观察小鼠游泳前、20min游泳中、游泳后20min小肠推进运动的变化。结果:20min游泳运动中小鼠小肠推进百分比降低,对照组为(60±7)%,实验组为(37±5)%;游泳运动后20min小鼠小肠推进百分比提高,对照组为(61±4)%,实验组为(66±5)%,差异均有显著性意义(t=10.254,2.908,P=0.000,0.008)。结论:20min游泳运动中小鼠肠动力减弱;游泳运动后小鼠肠动力提高。

AIM:To study the effect of swimming on the intestinal propulsive movements in rats. METHODS:Kuming rats were selected as experimental animals,and were randomized into two groups:control group and swimming group.The intestinal propulsive movements were observed before swimming,20 minutes during swimming and 20 minutes after swimming with the index of intestinal propulsive movements percentage. RESULTS:The intestinal propulsive movements percentage was decreased 20 minutes during swimming,which was(60±7)%in the control group and(37±5)%in the experimental group;The intestinal propulsive movement percentage was improved,which was(61±4)%and(66±5)%for the two groups, respectively,which indicated significant difference(t=10.254,2.908,P=0.000,0.008).CONCLUSION:The intestinal motility lessens 20 minutes during swimming;while strengthens after swimming.
