Research On Part Technical And Technical Training Characteristics Of Chinese Excellent Female Javelin Athlete Lv Huihui

Research purposes: China’s outstanding female javelin athlete Lv Huihui participate in the competition on behalf of the country many times and set new Asian records many times,becoming the leading figure in the new era of female javelin athletes.In order to understand Lv Huihui’s javelin throwing technique and technical training features more deeply,this article studies Lv Huihui’s technical moves and technical training features,tries to find out the advantages and disadvantages of Lv Huihui’s throwing technique,and explores the technology how training promotes the development of technology and thus achieves excellent athletic performance.It can also provide technical reference and theoretical basis for the training of high-level javelin athletes and javelin reserve talents;thus,to a certain extent,improve the competitive level of javelin athletes in China.Research methods and objects: This article uses literature data method,case analysis method,expert interview method,experiment method,mathematical statistics method to analyze some of the technical movements of China’s outstanding female javelin athlete Lv Huihui participating in the National Grand Prix Huangshi Station,and then through tracking The observation method summarizes the technical training features of Lv Huihui in 2018-2019.The research results and conclusions are as follows:1 Our country’s outstanding female javelin athlete Lv Huihui meets the internationally recognized standards for the last two steps and the step time,showing a "long-short" pattern;the torso angle of the torso of the last two steps shows a gradually increasing trend,but only The sixth shot reached 21.76 ° on the left foot,and the other few shots did not reach the optimal back-tilt angle of 20 °-25 °.Lv Huihui made five trial shots at the penultimate step when the left foot hits the ground—the last step when the right foot touches the ground—the last step when the left foot touches the ground.The trend is beneficial to increase the turning torque and increase the elastic potential energy of the trunk muscles.Lv Huihui’s angle between the last two steps of the hip axis and the throwing direction changes a lot,and has a better rotation,which is conducive to the final force of the javelin.2 China’s outstanding female javelin athlete Lv Huihui will have a good left leg braking ability in the final exertion stage;while the right elbow and pull angles are smaller in the final exertion stage,it is not conducive to the formation of "full bow" movements,which affect the order of the final force.The shooting parameters that affect the throwing performance are the shooting speed,the shooting height,the shooting angle,and the distance lost during the shooting.The shooting speed is the main reason that affects Lv Huihui’s throwing performance.3 Our outstanding female javelin athlete Lv Huihui has used a double-cycle training plan during 2018-2019 training.It divided into two preparation periods,two competition periods and two recovery periods,technical training runs throughout the annual training program.4 During the technical training of our outstanding female javelin athlete Lv Huihui,she paid more attention to the size of the last two steps,the big turning technique,cultivate the correct final exertion order and attach importance to combined technical training and other physical fitness training.
