Kinematics Analysis Of The Final Exertion Technique Of Some Young Female Shot Putters In Beijing-Tianjin Area

Women's shot put is a traditional competitive event in track and field in China.In the Tokyo Olympic Games in 2020,women's shot put was chosen as the gold medal event in China.In all previous world competitions,China's women's shot put has won more MEDALS than any other race walking event defending China's track and field honor.In promoting sports under the background of collaborative development of the beijing-tianjin-hebei region,give full play to women's shot put project in hebei province demonstration leading role in the training system,drive the beijing-tianjin region women's shot put project overall competitive level of ascension,promote women's shot put project and improve the beijing-tianjin region in the competitive landscape of our country's track and field events are relatively low.It is of great significance for China to maintain the sustainable development of women's shot put by strengthening the effective linkage of the coordinated development of reserve talents in women's shot put and improving the quantity and quality of reserve talents in women's shot put in Beijing and tianjin.Shot put is skills as the leading power project quickly,grasp the reasonable standard of shot put technique,and possess high competitive level to form unique technical style,depends in part on a teenager shot put technique training effect,but found that in the process of practice,because there are some errors in the coaches in the understanding of technology,caused many promising young players form a lot of difficult to improve technical error,thus the most promising to become a world-class elite athletes.In this regard,it is particularly important to strengthen the diagnosis and research on the shot-putting technique of reserve talents in the young women's shot-putting projects in Beijing and tianjin.In order to make the young athletes master the standard and reasonable technical movement structure and provide more technical and reasonable reserve talents for the shot put in China.This paper USES literature method,the three-dimensional video analytic method,and mathematical statistics in 2018,"Jordan cup" beijing-tianjin-hebei youth championships youth women's shot put final five athletes before the complete technology of backward slide of shot put as the research object of this paper,by studying the induces the shot-put athletes in the last several teenagers that exist in the technical aspects of action characteristics and technical deficiency,in order to help them better improve the theory of shot put training,guide the sports training practice,to climb the heights of shot put project competitive level lay a solid technical foundation.The results show that:1.In the transition stage,the phenomenon that the single support buffer time of the right leg is too long and the left leg is not positive when the leg is inserted;After landing on the left foot,it fails to form a good left braking and support,causing the left side of the body to move forward;During the transition to the last exertion stage,the right foot extension force is not positive;The phenomenon of premature trunk lifting is not conducive to the formation of a good beyond the instrument posture;2.During the transition from the transition stage to the final exertion stage,the athletes' bodies appeared to open too early;In the final exertion stage,the athletes' bottom-up power order is correct;The athletes' ankle joint kicks and extends well;3.In the final exertion stage,the braking and support effect on the left side of the juvenile athlete is not ideal;The throwing direction of the supporting leg is not enough for the positive inner buckle and the pushing force.In the last exertion stage,the technical movement is not coherent and lacks integrity,and the ideal man-ball integration state is not formed.4.The hand Angle of apparatus is relatively low for young athletes;In the hand speed of the equipment also need to have a greater improvement;In terms of shooting height,the best shooting Angle should be determined according to the technical characteristics and their own conditions.
