Research On The Technique Of Running And Jumping Of Elite Male Pole Vaulter In China

Modern pole vaulting technology,has been widely recognized by all walks of life,centered on the “human-pole” system,.The study on May 17,2017,the national track and field championships and national games in jinan trials before the men's pole vault final four athletes and held in tianjin on September 7,2017 the 13 th national games men's pole vault final top five athletes(grades)in 5.30 m or more run-up and take-off phase of the technical parameters as the main research object,based on the present situation of our men's pole vault movement,to the present stage our country outstanding man pole vaulter run-up and take-off technology are analyzed.From its key technology link rod run-up and take-off technology,the key factor of the gap with looking for high level athletes in the world and the shortage of individual expects to find out in the run-up and take-off technology restricting our men's pole vault grades improve the universality of the problem,fill the men's pole vault technology in China in recent years gap analysis,for the future of the key technical improvement of training practice provide empirical basis,in order to promote our country to further improve the men's pole vault score,and gradually close to the world level.The research results show that:1.The average number of steps for Chinese elite male pole vaulter to run with the rod is 17,and the length of the last three steps is gradually shortened,which is in line with the characteristics of the long regulation period of the pole vault.The difference of the length of the last three steps is small,which is obviously different from the average of the world excellent athletes.2.A rod run-up process,the speed of rising gradually,previous run-up speed is relatively stable,the last three steps speed change is most obvious,of which the most obvious change is at the speed of the last step,Xue Changrui glaring,an athlete pour step the average speed of up to 10.26 m/s,higher than the international level of existing data,other athletes run-up average speed are relatively low levels of excellent athletes in the world.3.Athlete's stride length that increases with the decrease of the pole,plug pole jump falls before step 2 to step between the reduction of the pole is the largest,the last two steps run down pole pole amplitude average 19.155 °,Xue Changrui and younglab sail two athletes andexcellent athletes in the world,numerical low or large than other athletes.4.The overall application effect of "free jumping" technology of elite male pole vaulter in China is relatively poor,which is reflected in the high loss rate of instantaneous horizontal speed from the ground,small center of gravity closing speed,and large starting Angle.5.The average distance between the projective point of the hand-holding point and the starting point is 18.25 cm,which is higher than the normal value on the whole,and the individual difference is large.In this study,there is no obvious correlation between the distance between the projective point of the hand-holding point and the distance between the jumping point and the athletic performance.
