摘　　要：目的:运用表面肌电分析拨法及揉法缓解肱二头肌运动性疲劳的作用,从肌肉层面揭示推拿作用机制。方法:以30名男性大学生为受试对象,随机分为休息组,拨法组,揉法组,首先以60%最大随意收缩力(MVC)为负重,使肱二头肌静力收缩至力竭以建立疲劳模型,并获取收缩时长(T),中值频率(MF)变化率,MF变化百分比,平均功率频率(MPF)变化率,MPF变化百分比,其次进行干预或休息,随后再进行静力收缩至力竭,再次获取表面肌电值,最后统计分析。结果:各组干预前后T、MF变化率、MPF变化率等比较均有统计学意义(P<0.05),拨法组及揉法组与休息组的干预后T、MF变化率和MPF变化率等比较有统计学意义(P<0.05),拨法组与揉法组之间比较无统计学意义。结论:拨法和揉法缓解肌肉疲劳的效果优于休息,两手法均能缓解肌肉疲劳,效果没有明显差异。Objective： Analyzing the effect of massage in alleviating muscle fatigue by sEMG to reveal the action mechanism of massage from muscle-level. Methods： Thirty Male volunteers from college were randomly divided into 3 groups, included rest group （control group）, plucking manipulation group （group A）, and rubbing manipulation group （group B）. Then volunteers were asked to contract their biceps isometrically to exhaustion in order to collect data： the contraction duration, MF slope, and MPF slope. Then the subjects were allowed to rest, received plucking manipulation treatment or rubbing method treatment. After the intervention, another 60%MVC isometric bleep contraction to exhaustion were carried out again, and sEMG data was collected again. Results： In comparison among groups, there was difference before and after intervention in the contraction duration, MF slope and MPF slope （P〈0.05）. After intervention, group A and group B were better than control group in contraction duration, MF slope, MPF slope （P〈0.05）. There was no difference between group A and group B. Conclusion： Both plucking manipulation and rubbing manipulation had better efficacy in alleviating exercise-induced bicep fatigue than rest. But there was no significant difference between plucking manipulation and rubbing manipulation in alleviating exereise-induced bicep fatigue.
