【摘要】：近几年以来,烟台市李维宾教练带领的铁饼投掷队员,在全国大赛中取得了优异的比赛成绩,其中他的队员冯彬更是其中的佼佼者,她的技术在一定程度上代表了李维宾铁饼队运动员旋转动作的特征。本研究采用文献资料法、运动现场拍摄法、数理统计法、对比分析法,对他的铁饼运动员冯彬的旋转技术动作进行分析,找到其技术动作的特性,从而更加全面、客观的认识其旋转技术,并通过比对国内的优秀运动员,找到其技术进一步优化应注意的问题。对冯彬研究结果表明,(1)旋转加速技术属于后速型,其完整技术用时也与世界水平存在一定的差距,旋转不同阶段的用时比例反映出动作技术具有合理的节奏。(2)“人-饼”系统在旋转过程的前两个阶段表现了良好的加速趋势,由于腾空和过渡阶段的“人--饼”系统整体变化的复杂性和难控制性,速度变化曲线呈现下降的趋势,中间重心短暂的加减速与铁饼速度变化不协同,造成了铁饼加速方面出现延迟。(3)在高速旋转的基础上,做到良好的身体重心位移距离,同时身体重心高度变化不大,保证了身体平稳的移动。(4)不同技术环节表现出的肩轴与髋轴形成的扭转角以及投掷臂与肩轴形成的拉引角数据,反映出她对身体及器械的良好控制状态。通过对冯彬旋转技术的分析可以看出李维宾铁饼队运动员旋转动作的特征,有助于其他运动员根据其技术风格,全面分析和诊断自己的技术,有针对性的吸收优点,从而达到提高其技术水平的目的。
[Abstract]:In recent years, the iron-cake-throwing team led by the coach of the Yantai city, Li Weibin, has achieved excellent performance in the national competition. By means of the literature, the field shooting, the mathematical statistics and the comparative analysis, the paper analyzes the rotating technology of Feng Bin, the discus athlete, and finds the characteristic of its technical action, so as to realize the rotation technology more comprehensively and objectively. And through comparison with the excellent athletes in the country, the problem that the technology is further optimized should be found. The results of Feng-bin's research show that (1) the rotation acceleration technology belongs to the post-speed type, and the whole technology time is also different from the world level, and the proportion of the time at different stages of rotation reflects the reasonable rhythm of the motion technique. (2) The "man-cake" system shows a good acceleration tendency during the first two stages of the rotation process, and the speed change curve exhibits a downward trend due to the complexity and difficulty of the overall variation of the "man-cake" system in the empty and transitional phases, The transient acceleration and deceleration of the center of gravity did not work with the change of the speed of the discus, resulting in a delay in the acceleration of the discus. And (3) on the basis of high-speed rotation, a good body center-of-gravity displacement distance is achieved, and at the same time, the height of the center of gravity of the body is not changed greatly, and the movement of the body is ensured. And (4) the torsion angle formed by the shoulder shaft and the hip shaft and the pull angle data formed by the throwing arm and the shoulder shaft are reflected in different technical links, so that the good control state of the body and the device is reflected. Through the analysis of Feng Bin's rotating technology, it can be seen that the characteristics of the rotating action of the athletes of the Li Weibin are helpful to the other athletes to analyze and diagnose their own technology comprehensively according to their technical style, so as to achieve the purpose of raising the technical level.
