Preparing For The Rio Olympics Women's National Team Shot Of Shotting Technique Kinematics And Dynamics Research

In this paper,we prepared and participated in the throwing technology of the elite women's shot put team in the 2016 Olympic Games.Some of the team members reached the A standard of the Rio Olympic Games and participated in the Grand Prix of the Rio Olympic Games,especially Gong Lijiao In 2015,Beijing track and field world championships shot finals made 20.30 m good results.In this paper,the author uses the methods of literature,expert interview,biomechanical test and biomechanical analysis to study the characteristics and technical performance of the main muscle of the shot shot of the women's shot put in the Rio Olympic Games.Through the analysis and diagnosis of the queuing technique of the team members,the main reasons for the technical characteristics and problems of the trainees are found,which are used to guide the training practice in the preparation period,and provide good results for the team members in the 2016 Rio Olympic Games.Technical support,the main conclusions are as follows:1 The right speed of the three main joints on the right side of the lower limb is as follows: right ankle> right knee> right hip,this rule is in line with the principle of "short,flat and fast" in the sliding step;Stage sliding distance is shorter;Gong LiJiao should be in the existing basic and special awareness of the appropriate increase in sliding distance.2 Gong Lijiao sliding stage with a longer time,sliding distance is short,pendulum technology is relatively smooth technical characteristics;Bian Ka sliding stage upper body lift earlier,the right hip force too early,the last hard effect is not ideal;And the formation of Guo Tianxi beyond the formation of the instrument posture,resulting in the speed of the sliding step in the final force stage has a certain degree of decline;sliding step trunk forelimate angle size and body mass center velocity changes were positively correlated.3 Transition stage from single support to double support in the process,Bian Ka on the shot of the acceleration is relatively better,but the end of the sliding stage into the transition phase,the Bian Ka to throw the direction of the body too early;Gao Yang and Guo tianxi 2 trainees from the right foot to the left foot to the moment the shot did not rise but did not rise,resulting in sliding step to get the shot speed has not been fully utilized.4 The last hard phase Gong LiJiao's shot speed is more ideal,but the four team members shot speed and my country before the outstanding women's shot player Li Meisu,Huang Zhihong compared to the existence of a certain gap,shot angle still need to improve,but the shot angle is not bigger it is good.5 Muscle strength test results show that the four team members in the best Gong Lijiao,knee flexion,extension of the power is not the largest;knee to do the same speed knee and knee,Bian Ka,Gao Yang,Guo Tianxi Than the Gong LiJiao knee flexion andextension force is not weak,which also reflects the side of the three team members shot the skills of the shortcomings of the shot;Chinese Women's shot put team want to make the ideal results in the Rio Olympic Games,coach team It should be in the training team under the premise of technical stability,increasing the strength of the four team members knee flexion and extension action for the team members to better form the side of the bow before the bow and anti-bow force to provide strong support to achieve as much as possible to make up The Goal of the Qualities of Elite Female Shot Putters in Foreign Countries.
