Pre-tournament Training And Technical Analysis Of Chinese Elite Woman Discus Athlete SU Xinyue

Women's discus is the earliest throwing event that joined the world's advanced ranks in China's track and field history.At the training time,the discus project is also a complex sports advantage in our province,and Su Xinyue is the leading figure in Hebei discus project.In recent years,the development of discus project in China has been greatly promoted and the gap between the development level of our discus project and the international level has been narrowed.Nowadays,with the increasing number of professional competitions,how to reasonably arrange the training cycle to ensure the athletes to keep a good competitive state under the condition of frequent participation is one of the hot spots in the field of sports training.^[1]Only in good state,can athletes get excellent achievement,so the pre-tournament training arrangement of training methods and the scientific nature and rationality of load is the important factors that affect athletes form and technical performance,therefore,to our country outstanding female discus athletes Su Xinyue pre-match training program analysis,and through the analysis of its national games discus technique,discusses the pre-match training arrangement of the rationality and scientific nature.Therefore,we did a careful research about the pre-tournament Training and the preparation for the 13th National Games of Su Xinyue,the Chinese outstanding female discus athlete by using document-data method,three dimensional video analysis method,interviewing method and comparative analysis method,striving to fully combines the movement rule of discus and project characteristics.It plays a significant and practical role in guiding the physical training of discus,providing certain reference basis for the coaches in training practice,as well as preparing Su Xinyue well for the 2017 National Games and had an amazing performance.1.Research objectives:Given the national significance of the domestic top comprehensive sports event,determines the achievements of discus in the national games has a strong representative,the athletes'grades technical performance has a direct relationship with the game,and its training,preparation,before the arrangement is scientific or not directly determines the performance athletes in the competition of technology,by studying the Su Xinyue national games before arrange training cycle,training means and load,and in the competition sports technical performance,summarizes Su Xinyue training experience,sports technology performance analysis of the problems existing in the training.2.Research objects:This study takes Su Xinyue,an excellent female discus thrower in China,as the research object.The pre-competition training mainly takes the related games around the national games as the node to carry on the related special technical analysis.At the same time,literature,interview,video analysis and case study are used to carry out related research.3.The research results:1)In the process of Su Xinyue thrown by shoulder hip twist Angle analysis,its biggest moment is placed in the pre shoulder hip Angle is 89.7°,his right foot off the ground moments of shoulder hip Angle is 46.6°,the amplitude change of 43.1°,that means Su Xinyue shoulder hip twist Angle increases obviously,better reflect the Su Xinyue rotation speed,the acceleration of the stability of the torso to keep the more obvious trend.At the same time,the control of the instrument is good,pulling Angle change range is small,instrument acceleration is very obvious.2)At the moment when Su Xinyue threw the instrument,the legs,hip,knee and ankle joints were extended sufficiently,and the"left support"was relatively stable.3)the legs support rotation stage,appropriate to increase the distance between the legs,try to maintain a smooth rotation of the body,keep the shoulder,pith rotation speed.4)By Su Xinyue throwing pull Angle analysis,in the process of its pull in pre set maximum instantaneous angular extent reached 125.2°,right foot off the ground instantly pull Angle is 152.9°,the amplitude change of 36.5°,suggesting that Su Xinyue gained by the maximum force distance increased,strengthen the training of the special power to action,improve the athlete's hand speed;Maintain good overarm movement,keeping the throwing arm behind the body as much as possible to improve the Angle of hand.4.The conclusions:1)Su Xinyue training to prepare for the annual national games of load characteristics:mainly USES large load and strength training program,including the run-up to strength training by the moderate intensity physical training,gradually transition to the special big load load intensity,so reasonable arrangements for the training load stable competitive level of play in the game has played a positive role.2)In the special technology,although Su Xinyue already very good,but the technology exists in the process of the rotating motion with fast,high center of gravity height and left-side strut instability problems,such as the coach for the above technical problems adopted a special resistance to stem the imitation and practice means such as rotating crank arm pull belt to be correct,and increase the proportion of the special technology in the training.
