膏摩对运动后肌肉疲劳恢复的机理研究

摘要

Objective To observe the curative effect of ointment-massage on post-exercise muscular fatigue in SD rat models and to explore the possible mechanism. Methods Thirty-two male SD rats had been randomly divided into four groups:normal group, model group, ointment-massage group, and massage group. The rats in all the groups except normal group were designed to run regularly to establish models, and each group was treated with corresponding treatment. Three weeks later, each rat’ s left rectus femoris would be separated to observe the activity of SOD to measure the content of MDA. Results It turned out that the difference of the results of SOD/MDA between model group ( 36. 485 ± 3. 455 ) and normal group(57. 204±2. 852) was statistically significant (P<0. 01), the differences of SOD/MDA among model group, ointment-massage group and massage group were statistically significant (P<0. 01). Also, the results of SOD/MDA turned out that ointment-massage group (49. 103±2. 786)is higher than massage group(42. 938±3. 278). Conclusion The ointment-massage can produce a curative effect on post-exercise muscular fatigue and accelerate metabolisms of free radicals.%目的：观察膏摩对运动后肌肉疲劳大鼠的恢复疗效并探讨发挥作用的可能机制。方法将正常SD雄性大鼠32只按体质量均衡和随机的原则分为正常组、模型组、膏摩组、按摩组。对模型组、膏摩组、按摩组进行运动疲劳造模,并对膏摩组使用膏摩处理,对按摩组使用按摩处理,3周后,取出左腿股直肌测量其过氧化物歧化酶( superoxide dismutase,SOD)活性与丙二醛(malonaldehyde,MDA)含量。结果正常组大鼠的 SOD/MDA 比值(57.204±2.852)与模型组(36.485±3.455)比较差异有统计学意义(P<0.01),模型组、膏摩组、按摩组3组SOD/MDA比值两两比较均有统计学意义(P<0.01),且膏摩组 SOD/MDA 比值(49.103±2.786)高于按摩组(42.938±3.278)。结论膏摩对于运动后肌肉疲劳有缓解作用,并可加速自由基的代谢。
