链球论文：我国男子高水平链球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:国内利用肌电技术对链球运动员最后用力阶段肌群方面的研究至今还未发现。本文旨在探讨利用表面肌电图对运动员投掷过程中最后用力阶段的主要肌群进行全程监测和肌电分析,以期通过数理统计、逻辑推理及表面肌电分析得到的数据能够有效地判断运动员的肌肉用力以及技术动作的差异性,帮助教练员了解运动员在技术训练中应注意的问题及侧重点。从而构建出我国链球运动员最后用力阶段表面肌电模式,为以后的研究提供理论依据。研究方法:本研究用芬兰MuscleTesierME6000便携式8导肌电遥测仪对十名高水平男子链球运动员的最后用力单支撑阶段和双支撑阶段进行了现场肌电测试描记,用Megawin软件并结合同步视频对选定的八块主要肌肉进行肌电分析。研究结果:1、在掷链球最后用力单支撑阶段右股二头肌、左前胫骨肌和左胸大肌在肌电图上它们显示放电较早,肌肉贡献率最大,均方根振幅平均值较大,肌肉放电的同步化比较高,肌肉持续的时间也比较长。在此阶段,以上几块肌肉在单支撑阶段不仅在发力时序上起着重要作用,而且在肌肉贡献率上也扮演着重要作用,在有关掷链球最后用力单支撑阶段动作的训练中,应特别加强以上几块肌肉的全面力量训练。2、在掷链球最后用力双支撑阶段右股二头肌和左胸大肌在肌电图上显示放电最早,左胸大肌、右腕关节屈肌群和右斜方肌在肌电图上它们显示肌肉肌电积分值贡献率较大,均方根振幅平均值也较大,肌肉持续的时间也比较长,其中左肱二头肌积分值贡献率和均方根振幅平均值最大。在此阶段,以上几块肌肉在最后用力双支撑阶段起着重要。这也提示我们,对于不同动作的力量训练,应有不同的侧重点,在有关掷链球最后用力双支撑阶段动作的训练中,应特别加强以上几块肌肉的全面力量训练。而对于肌肉发力的时序,应根据其发力顺序,建立合理的动作训练基础,着重训练各肌肉相互配合的协调性。
【英文摘要】: The research in which the domestic use muscle electrical technology to hammer athletes at the final stage of shot-putting muscle group has not yet been discovered. This article aims to explore using tables for the athletes throwing semg electric chart during the final stage of shot-putting major muscle groups for the whole monitoring and muscle power analysis. By the mathematical statistics, logic reasoning and table semg electric analysis data obtained, the author hope to judge effectively athletes of the muscle and technical movements, and help coaches understand the differences in technical training athletes problems to be noticed and emphases. Thus we construct our hammer athletes at the final stage of shot-putting table semg electric pattern, to offer a theoretical basis for future research. Methods: We studied by Finland MuscleTesierME6000 portable 8 guide flesh report telemetry apparatus on ten high level man hammer athletes last forcibly single support phase and the double support phase conducted on-site muscle electrical testing, with Megawin software and the synchronization video of selected eight main muscles for the muscle electric analysis. Results:1, single-support phase in the last hard right femoral biceps, left shin and left pectoralis major muscle EMG display them in the discharge of the first; average amplitudes greater synchronization of muscle discharge is relatively high; the duration of muscle also relatively long. At this stage, more than a few muscles in single-support phase in the development effort not only plays an important role in the timing and size of the force in the hair also plays an important role in force in the hammer throw final stage of single-action training support, should more than a few muscles in particular to strengthen the overall strength training.2, double-support phase in the final force the right and left pectoralis major muscle in the biceps femoris EMG discharge was first shown on the left pectoralis major muscle, wrist joint flexor group and right trapezius EMG display them in the muscle EMG integral value greater contribution, the average amplitude is large, the duration of the muscle is relatively long, of which the value of the left biceps contributed the most points. At this stage, more than a few muscles in the final phase of double support plays an important force. This suggested to us that, for different actions of strength training, the focus should be different, in the hammer throw final double support phase of the action force training, should be more than a few muscles in particular to strengthen the overall strength training. As for the timing of muscle development effort should be made according to their strength in order to establish a reasonable basis for the action training, focusing on training the muscle coordination with each other.
