摘　　要：采用成年雄性SD大鼠40只,随机分为安静对照组、小强度组、中等强度组和大强度组。测定骨骼肌中SOD活性、MDA的含量。试验结果是,小强度运动组较安静组比目鱼肌中SOD活性降低,MDA含量降低;中等强度运动组较安静组肱二头肌中SOD活性升高,MDA含量降低。通过比较不同强度持续运动对大鼠不同类型骨骼肌自由基代谢的影响,探讨合理的运动强度,为健康的健身运动提供科学方法与理论依据。40 adult male SD rats are randomly divided into sedentary control group,low intensity group,moderate-intensity group and the high intensity group.Their SOD activity and MDA contents in skeletal muscle are measured.The results show that： soleus muscle＇s SOD activity and MDA content in the low intensity group are lower than those in the quiet small group,biceps SOD activity in the moderate-intensity group are more than that in the quiet small group,but MDA content has decreased.By comparing the effects of different continuous exercises on different skeletal muscle free radicals metabolism,explores reasonable exercise intensity and provides scientific methods and theoretical basis for healthy exercise.
