摘　　要：目的:探讨沙棘汁对大鼠骨骼肌自由基代谢和血液部分生化指标的影响。方法:30只SD大鼠随机分为安静组、训练组、沙棘训练组,6周训练和补充沙棘汁后,测定大鼠骨骼肌和血液的有关指标。结果:沙棘训练组与训练组相比,运动至力竭的时间明显延长;骨骼肌抗氧化酶活性明显升高,丙二醛(MDA)含量极为显著降低;血睾酮(T)和血红蛋白(Hb)均明显升高;肌酸激酶(CK)显著降低。结论:沙棘汁能增强大鼠骨骼肌抗氧化能力,提高血睾酮和血红蛋白水平,延缓疲劳出现,提高其有氧耐力运动的能力。Objective： To explore the effects of hippophae juice on free radical metabolism of rat skeletal muscle and partial biomarkers in blood. Methods： Randomly dividing the 30 SD rats into 3 groups（ n = 10） ： sedentary group, training group and hippophae training group. Measuring related indices of skeletal muscle and blood in rat after 6 week training and hippophae juice supplement. Results： Compared with training group, hippophae training group showed obviously longer exhaustive time, significantly increased antioxidant enzyme in skeletal nmscle, remarkably decreased malonaldehyde（MDA） content in skeletal muscle, obviously increased testosterone （T） and hemoglobin （Hb） content in blood, significantly decreased creatine kinase （CK）. Conclusion： Hippophae juice can impove the antioxidant ability of rat skeletal muscle, the level of T and Hb in blood, delay fatigue, therefore effectively enhance the aerobic stamina of rat.
