【摘要】 目的探讨高脂肪食物的摄入和运动对骨骼肌的脂类及糖类代谢的影响特点。方法采用44只体重在60~80g的Wistar雄性小鼠为实验对象,将它们分为标准食物的对照组(N),食高脂肪食物组(F),非运动组(S)和运动组(T)四组。每组各11只小鼠,饲养五周,然后将解剖取出副睾丸脂肪组织,肝藏,比目鱼肌,外侧包括的肌肉,肌腱和血液。进行血液性状,脂肪分辨力,糖原含量,酶的活性进行测定。结果高脂肪食物的摄入和耐力运动训练对ep-itrochlearis肌肉中肌糖原的影响具有显著性(P<0·05,P<0·001)高脂肪食物和耐力训练对副睾丸脂肪组织的脂肪分解表现出显著性差异(P<0·001,P<0·001)。摄入高脂肪食物和耐力训练对epitrochlearis肌肉中氧化酶cs的活性也具有显著性影响(P<0·05,P<0·001);对脂肪酶氧化酶3-HAD活性的影响非常显著(P<0·001)。结论高脂肪食物摄入虽然使骨骼肌肉内糖原含量降低,但可使氧化酶的活性增强,运动训练可使脂肪酸氧化酶的活性显著提高。更多还原

【Abstract】 Objective To investigate the influence of food rich in fat and exercise on skeletal muscle and the metabolism of sugar. Methods 44 wistar male mice weighing between 60～80 g are used as subjects. They are classified into four groups:comparative group of standard food(N), group of food rich in fat(F), non-exercise group(S) and exercise group(T), with 11 mice in each group for a feeding period of 5 weeks. By the end of fifth week, the mice are intersected for the removal of such organs as fat tissue of secondary testicles, liver, flatfish muscle, the muscular fiber of out-stretch muscle, tendon and blood. Then measurement is taken of the blood property, fat resolution capacity, the amount of glycogen, the activity of enzyme. Results The in-take of food rich in fat and stamina training has demonstrated a strong influence on muscular glycogen of epitrochleanis muscle(P<0.05, P<0.001), the in-take of food rich in fat and stamina training has displayed a differentiation in the resolution of fat of secondary testicles(P<0.01, P<0.001). the in-take of food rich in fat and stamina training have an obvious impact on the activity of oxidized enzyme(cs) of epitrochleanis muscle(P<0.05, P<0.001). It also showed a strong influence on the activity of the oxidized enzyme of fatty acid(P<0.05, P<0.001). Conclusion Although the in-take of food rich in fat has reduced the amount of glycogen in the skeletal muscle, it increased the activity of oxidized enzyme. Exercise has obviously increased the activity of oxidized enzyme of fatty acid.更多还原
