Track and field events have always been the largest in competitive sports,including 46 minor events.The development of track and field is of great significance to the development of competitive sports in China.It can be seen from the previous national track and field championships and national Games that there is an obvious gap between the triple jump results of men and the triple jump results of the United States track and field championships.After consulting the relevant videos and videos of the national Track and field championships and the National Games in recent years,it can be seen that the triple jump is a relatively slow performance improvement event in the national track and field events,and there are some problems and deficiencies in the training.So this thesis aims to triple jump national athletics championship final in2019 of the top three players,triple jump and the national athletics championship of the top three players to jump three comprehensive analysis technique,hope the comparative analysis of the results to improve the China men’s triple jump results provide enlightenment on the training and help.The significance of this paper is to deepen the understanding of the key parameters of men’s triple jump performance,clarify the direction of triple jump training,and provide technical and theoretical support for national men’s triple jump athletes to improve their performance.In this paper,the top three athletes in the men’s triple jump final of the 2019 National Track and Field Championships and the top three athletes in the men’s triple jump final of the United States Track and Field Championships were selected as research objects.Using the literature material law,survey method,experimental method,mathematical statistics methods,technical features of men’s triple jump athletes’ physical qualities,lower limbs explosive force and flexible coordination and various restricting the current factors of elite male triple jump competition performance,project in-depth comparative analysis research,give the rationalization suggestion for improvement of China’s men’s triple jump.By triple jump national athletics championship in 2019 before the triple jump three players,and the national athletics championship three members before the field of video technology analysis our country the players in the triple jump technology reflects the stude screws and takeoff Angle significantly lower than the United States,the third jump far degree is significantly lower than the American players,moments before and after takeoff speed is slightly lower than America’s level of players,the last four steps approach velocity and takeoff instantaneous velocity are lower than in the us players,three jump movement technical performance and fluency than American players,support the triple jump overall physical quality players,weak in our country.
