摘　　要：通过分析大强度耐力运动训练大鼠(♂)部分自由基指标的变化来探讨补充茜草提取物抗氧化、提高机体抗疲劳能力的可能机制。方法:通过建立大鼠递增大强度耐力跑台训练实验模型,测定了大鼠肾脏组织某些生化指标和抗氧化酶活性影响。结果:茜草可增加耐力运动后力竭即刻状态下谷胱甘肽过氧化物酶(GSH-Px)、还原性谷胱甘肽(GSH)、过氧化氢酶(CAT),降低丙二醛(MDA)以及活性氧(active oxygen)含量。结论:补充茜草提取物可显著提高大鼠肾脏组织抗氧化酶的活性,减轻大强度耐力训练对大鼠肾脏组织造成的脂质过氧化损伤,具有明显的抵抗脂质过氧化的功能,对大鼠运动能力的提高有良好的作用。By using the experiment model of training rats on the endurance running-platform to test the changes of the biochemistry indexes and the antioxidant activities of antioxidant enzymes in their kidney,this article analyses their alterations of partial free radicals after high-intensity endurance training,probes into the potential mechanisms of supplementing gamene extractive to antioxidation and develop anti-fa-tigue ability of organism;and gets the result that supplementing gamene extractive could significantly de-velop the antioxidant activities of antioxidant enzyme;there is fine function for rats＇ sports ability.
