标枪运动员论文：我国男子优秀标枪运动员最后用力阶段主要用力肌群表面肌电分析
【中文摘要】研究:本研究尝试将肌电图引入标枪投掷技术的研究当中,试图构建标枪最后用力阶段的肌电图模式,通过研究来检测肌肉用力的顺序、贡献率,从而有针对性的改进某些肌肉的训练方式和手段,从一个全新的角度来阐明标枪最后用力技术的科学合理性,为改进和合理化肌肉力量训练计划提供理论依据。研究方法:本研究运用芬兰产MuscleTesierME6000便携式8导肌电仪对9名一级及以上优秀标枪运动员的投掷动作进行信号采集,并运用处理系统中的分析软件进行主要肌肉活动状态的肌电分析。结论:1标枪运动员最后用力的准备部分:(1)最后用力准备部分各肌肉的开始放电顺序符合“大关节首先活动的原理”,但有些运动员在最后用力准备部分由于对标枪没有很好的控制导致桡肌首先发力;(2)腹外斜肌和股二头肌在整个最后用力阶段一直持续用力;(3)在最后用力的准备部分中,应缩短从单脚支撑过渡到双脚支撑所需的时间,提高水平速度利用率;(4)有些运动员在最后用力准备部分三角肌和斜方肌的贡献率偏高,说明在此部分三角肌和斜方肌过于紧张,整体的肌肉协调性较差,应对肌肉协调用力加强练习。2标枪运动员最后用力的加速部分:(1)最后用力加速部分所测运动员腹外斜肌都最先发力,在完成“满弓”动作时,腹外斜肌已经得到充分的拉伸,在最后用力加速部分开始时刻快速收缩用力,使躯干带动投掷臂向前,对标枪出手时的“鞭打”加
速起到积极的作用;(2)最后用力加速部分肌肉肌电活动结束的先后顺序中,前胫骨肌首先结束发力,其次是腹外斜肌和腓肠肌,桡肌和三角肌最后结束发力,符合由下至上发力,使动量由下肢传至躯干,再由躯干传至投掷臂;(3)结合同步录像可以看出,最后用力加速部分三角肌的贡献率偏小,可能与重心偏高上体偏直,“满弓”动作不充分,幅度偏小,“鞭打”动作未用全力等因素有关。
【英文摘要】Object: This research attempts to introduce Javelin Throw EMG studies were,Javelin stage of trying to build the EMG patterns, By studying the muscle in order to detect the contribution rate, Which targeted certain muscles to improve training methods and means, From a new angle to illustrate the javelin Technology rationality of science, To improve and rationalize the muscle strength training program provides a theoretical basis.Method: In this study, produced in Finland MuscleTesierME6000 8-lead portable EMG Of the nine outstanding athlete throwing the javelin for signal acquisition, Analysis software for the major muscle active EMG analysis.Conclusion:1 Javelin Thrower Final Exertion Preparation part:(1)The last strength prepare parts muscle began to discharge sequence in accord with “large joints, first activities, but some athletes principle in the last strength ready to part due to no good control cause javelin radial muscle first send force;(2)
Abdominal muscles and external oblique biceps throughout the last stage of shot-putting continued strength;(3)In the last strength preparation part, should shorten single-support transition from the time required to support both feet, raise the level of speed utilization rate;(4)Some athletes in the last strength ready to part deltoid muscle and trapezius muscle, the contribution that high in this part and deltoid muscle and trapezius muscle too nervous, whole muscle coordination is poorer, deal with muscle coordination force strengthen practice.2 Javelin Thrower Final Exertion Acceleration part:(1)The last strength accelerate part nine athlete abdomen is outside the oblique muscle in the strength, complete “full bow” action, abdomen has been fully outside oblique muscle tension, in the last strength accelerate section begins moment, make rapid contraction force driving throwing arm forward, the torso of the “thrash javelin moves when accelerating” play a positive role;(2)The last strength accelerate muscles muscle electrical activity in the end, the order of tibial muscle first before end sends force, followed by external oblique muscle and seated abdominal muscle and deltoid muscle, radial send force, accord with the closing bottom-up sends force by lower limbs, make momentum to the torso, again by throwing arm to the
torso;(3)With simultaneous video can see, the last strength accelerate the contribution of part deltoid muscle with smaller, its high center of gravity, probably, “partial straight full bow” action not fully, the amplitude slants small, “whip” action not related to such factors with all our strength.【关键词】标枪运动员 最后用力阶段 主要用力肌群 肌电分析 【英文关键词】Javelin Thrower Final Exertion Major muscle force EMG analysis 【目录】我国男子优秀标枪运动员最后用力阶段主要用力肌群表面肌电分析7-157摘要5-6
