摘　　要：为从积分肌电、贡献率、时序、时程等角度识别跆拳道横踢技术的肌肉用力特征,以横踢技术动作(右腿)为技术标准,通过Noraxon表面肌电遥测系统对选取的7名跆拳道队运动员进行测试,结果表明:(1)在发力时序上,在各个阶段中都表现出左侧肌群优先用力的动作特征;(2)左竖脊肌的放电量、贡献率和肌电持续时间都相对较长.研究得出结论:(1)左侧肌群虽然不是横踢技术过程的主要做功肌群,但作为支撑发力肌群,对控制身体平衡和发力具有重要作用.(2)在左侧肌群中,左竖脊肌在整个肌群中都发挥着重要作用,且应重视左侧肌群的支撑训练.(3)左竖脊肌、左胫骨前肌等左侧肌群和右半腱半膜肌、右股二头肌等右侧肌群的协调用力是完成动作的重要保障.The research objective is to identify the muscle force characteristics of taekwondo horizontal kick technique from the perspectives of integral myoelectric,contribution rate,time sequence,and time course.Using the horizontal kick technique(right leg)as the technical standard,the Noraxon surface EMG telemetry system was used to test the selected 7 taekwondo team athletes.Results show that(1)In the timing of force generation,the action characteristics of the left muscle group preferential force were shown in each stage;(2)The discharge amount,contribution rate and electromyo electric duration of the left erector spinal muscle are relatively long.Conclusion:(1)Although the left muscle group is not the main work muscle group in the process of horizontal kicking technique,it plays an important role in controlling the balance and force of the body as a supporting mus-cle group.(2)In the left muscle group,the left erector spinal muscle plays an important role in the entire muscle group,and the support training of the left muscle group should be paid attention to.(3)The coordinated force of the left muscle group such as the left erector spinal muscle and the left tibial anterior muscle and the right muscle group such as the right tendon and half membranous muscle and the right biceps muscle is an important guaran-tee for completing the action.
