摘要：

      摘要 目的：通过观察电针疗法对单纯性中度抗阻训练后肌肉损伤相关因子活性的影响,探究其对运动肌肉损伤可能的保护作用。 方法：30例男性志愿者（年龄20—25周岁）按随机数表法分为治疗组15例和对照组15例。两组受试者接受为期5d，每天3组，每组20次的腿举训练。训练前接受评估，使腿举重量为受试者最大腿举重量的70%。每次训练结束后治疗组给予30min的电针治疗，选择足三里-条口、承山-委中两组对穴；对照组不做特殊处理，嘱充分休息。训练前及每次治疗结束30min后抽取受试者血液样本以检测肌酸激酶（creatine kinase，CK）和乳酸脱氢酶（lactic dehydrogenase，LDH）活性。训练前后采用等速肌力测试系统检测膝关节屈伸肌峰力矩值（peak torque，PT）和平均功率（average power，AP）。 结果：首次训练后两组受试者血液样本中CK和LDH活性均显著提升（P<0.01），5d内对照组两项指标均高于治疗组（P<0.01），治疗组CK在第3天后开始下降；5d训练治疗后治疗组膝关节屈伸肌峰力矩值和平均功率高于对照组，较训练前也有所提高（P<0.05），对照组训练前后无明显改变（P>0.05）。 结论：中度的抗阻训练可以对肌肉组织产生一定的损伤，电针治疗能够降低相关因子的活性，促进损伤肌肉和运动能力的恢复，能够有效地运用到运动过后肌肉损伤的康复治疗中。

Abstract:

      Abstract Objective: By observing the effects of electro-acupuncture therapy on related factor activity in the skeletal muscle after moderate resistance training, to explore its possible protection effects against exercise muscle damage. Method: 30 male volunteers (age: 22—25) were divided into treatment group (15) and control group (15) according to random number table. Both two groups received the leg press training for 5 days and the training was performed for total 60 times per day that were divided into three times to complete. The press weight was 70% max ability of volunteers, which was evaluated before the training. The treatment group accepted the electro-acupuncture therapy 30 minutes after the training at two groups of acupoints（“Zu San Li-Tiao Kou,Cheng Shan-Wei Zhong”） and the control group was just asked to get enough rest. Before and 30minutes after every treatment, we tested the activity of creatine kinase and lactic dehydrogenase in the blood sample of volunteers . We also used the isokinetic muscle testing system to test the knee joint peak torque and average power before and 5 days after training. Result: The creatine kinase and lactic dehydrogenase increased significantly after first training in two groups (P<0.01). However, control group had significantly higher level than treatment group during the five days (P<0.01). The creatine kinase began to decrease after 3 days in the treatment group. There was a significant improvement of knee joint peak torque and average power in treatment group compared with itself before training (P<0.05) and the control group which had on change after training (P<0.05). Conclusion：Moderate resistance training can produce certain damage to muscle tissue. Electro-acupuncture therapy can reduce the activity of the related factors, promote the recovery of muscle injury and athletic ability and be applied to the rehabilitation treatment of muscle damage.
