| 摘 要： | 目的:探讨负重训练和补充大豆多肽干预大鼠骨骼肌衰老过程的作用效果.方法:56只雄性SD大鼠随机分为7组:成年组,模型组,D-半乳糖小负重组,D-半乳糖大负重组,D-半乳糖补肽组,D-半乳糖补肽小负重组,D-半乳糖补肽大负重组.6周后处死大鼠,制作冰冻切片,测试血清以及骨骼肌各项指标.结果:与成年组相比,模型组大鼠体重和每日摄食量分别呈现升高和下降的趋势,负重和补肽可以在一定程度上缓解两种趋势,但都无统计学意义;模型组大鼠骨骼肌细胞出现萎缩和退行性改变等衰老的迹象,负重和补肽可以在一定程度上减轻这种现象;模型组大鼠血清SOD、SOD/MDA比值和骨骼肌总蛋白含量显著低于成年组,血清MDA显著高于成年组,运动和营养干预各组显著逆转这种趋势,并有明显的交互作用;与成年组相比,模型组大鼠骨骼肌脂褐素含量显著升高,负重或补肽可以一定程度上缓解或逆转这种趋势,两种具有明显的交互作用.结论:负重训练或补充大豆多肽均可以有效的预防大鼠骨骼肌衰老过早的出现,两种方式联合运用效果更为明显.
