足三里穴不同干预方法对运动性疲劳的影响

目的：观察足三里穴不同方法干预对运动性疲劳大鼠内环境的影响。方法：本实验通过四周递增游泳训练，建立慢性运动性疲劳大鼠模型，采用“逆针”在造模同时进行治疗，将大鼠随机分为温针灸组、电针组、普针组、模型组、空白组，每组各10只大鼠。在第4周末进行大鼠力竭游泳，观察大鼠血红蛋白、血乳酸、尿素氮、肌酸激酶的变化。结果：各治疗组均可提高血红蛋白水平，降低尿素氮、肌酸激酶、血乳酸水平（P＜0．05），具有显著性差异，其中温针灸组具有极显著性差异（P＜0．01）。结论：温针灸组、电针组、普针组均能够有效改善运动性疲劳大鼠生化指标，从而有效地改善大鼠疲劳程度，其中温针灸组效果最佳。

Effect of Different Acupuncture Methods at Zusanli Point on Exercise-induced Fatigue

Objective：To observe the effect of different acupuncture methods at Zusanli point on exercise-in-duced fatigue Methods：Create the rat models with exercise fatigue by 4-week incremental swimming exercise, and randomly divide the rats into 5 groups： blank group, model group, nomal-acupuncture group,electric-acupuncture group and needle warming moxibustion group.Adopt the method of“preventive acupuncture”.De-tect the changes of the whole blood lactate, creatine kinase, urea nitrogen, hemoglobin in rats after incremental swimming exercise.Results：All of the treatment groups could increase Hb level,and BUN,LA,CK were de-creased （P〈0.05）.The effect of needle warming moxibustion group was remarkable （P〈0.01）.Conclusion：Nomal-acupuncture group, electric-acupuncture group and needle warming moxibustion group can effectively improve the symptoms of exercise-induced fatigue of rats on biochemistry indexes and thus effectively alleviate the level of fatigue in rats.Among these groups, needle warming moxibustion group is the best.
