The Comparative Study Of The Difficulty And Arrangement Of Chinese And Foreign Excellent Male Athlete's Movement In The Thirty-first Olympic Games Trampoline Competition

The competitive level of the men's individual trampoline project in China is in a leading position in the world,however,foreign players' competitive level is also rising,we must know ourselves and make an innovation if China wants to continue to maintain and expand the superiority of our trampoline project.This paper uses the method of literature,interview,video observation,mathematical statistics and comparative analysis to compare the difficulty selection and arrangement of the excellent male and Chinese athletes in the 31 st Olympic Games during the trampoline competition.To improve the competitive level of Chinese men 's trampoline athletes to provide theoretical reference.The results show that:1.The complete difficulty and movements of preliminary provisions: just count two difficult movements in a complete series of movements,the other eight movement are single circle,the range of the complete difficulty was between 3.1and 3.5,Gao Lei and Dong Dong in our country were 3.4 and 3.3,bellowing Andrey YUDIN in Russian and Japanese Masaki ITO with 3.5 in difficulty,however,Gao Lei in our country won the championship with high score of accomplishment and high.The result of complete difficulty and movements of preliminary provisions shows that Chinese athletes and other foreign athletes all select to complete the ninth and tenth movements the provisions set arrangement,in addition to the two Russian athletes select the first two movements of the first computational difficulty of choreography in the preliminary round of the provisions and select the second computational difficulty of choreography in last movement.It can be seen,the first set of preliminaries set the trend of the arrangement is difficult to move on both ends of the action,the most difficult action on the set of the last action more.2.The complete difficulty and movements of the final: the range of the complete difficulty value is between 16.7and 18.4,Gao Lei in our country was 18.4 in difficult points higher than other countries,Ginga MUNETOMO in Japan and Dong Dong in our country were in the second and third,the difficult points of the remaining players had little difference.Because of the trampoline competition is not only judge according to the difficulty,so GaoLei did not win although he had the highest difficult points,but Belarus athlete Uladzislau HANCHAROU won with higher points in completion and high.The final free complete arrangement shows that the curve graph of the free complete arrangement was shape as U in the whole,the difficult points value at the beginning of it is most difficult.In the 10 arrangement of movement,Dong Dong in China in the 5 position of 1,2,3,4,10 which are the higher difficulty,while Gao Lei was in the 6 position of 1,2,3,4,5,10,other foreigners in the 4 positions of 1,2,3 and 10.Gao Lei's movement is more difficult and has some flaws in the completion and connection of complete sets of movements.3.Difficulty and layout of somersault: the difficulty of the somersault in preliminary provisions is moderate,single difficulty of the somersault distribute in 1-1.6,complete sets of somersault difficulty distribute in 2-2.6,the difficulty of the somersault of two athletes in China and Uladzislau HANCHAROU in Belarus,Andrey YUDIN in Russia were all 2.6higher than athletes in other countries;the difficulty of the somersault in the final was moderate,single difficulty of the somersault distribute in 1-1.6,complete sets of somersault difficulty distribute in 11.8-13.6,the difficulty of the somersault of Gao Lei in China was the highest,Dong Dong in China and Ginga MUNETOMO in Japan were the second,the difficulty of the somersault of athletes in other countries was lower.The results show that the arrangement of somersault elite trampoline athletes are to choose the front flip,flip(5:5)alternate arrangement;in flip weeks excellent male athletes at home and abroad are mostly in three week and two weeks ago in action,in action after the order of a few athletes between the three week of action with two weeks of action as a buffer,the Chinese athletes flip weeks athletes more than other countries.4.Difficulty and arrangement of rotation: the difficulty of the swivel in preliminary provisions is moderate,single difficulty of the swivel distribute in 0.1-0.8,complete sets of swivel difficulty distribute in 0.3-1.1,the difficulty of the swivel of Japan,Russia and New Zealand athletes was the highest,the difficulty of the swivel of Chinese athletes was lower;the difficulty of the swivel in the final is moderate,single difficulty of the swivel distribute in 0.1-0.6,complete sets of swivel difficulty distribute in 2.5-3.1,the difficulty of the swivel of Gao Lei in China,Belarus athletes and two Japan athletes were the highest,the difficulty of the swivel of Dong Dong in China was lower.The swivel arrangement results show that most of Chinese and foreign elite athletes is 540 degrees,360 degrees and 180 degrees in front,and 720 degrees,900 degrees and 1080 degrees in the order of a few athletes in the last three sets of 180 or 360 degrees of rotation.Thedegree of twist arrangement varies little from country to country,and the choices are similar.5.Difficulty and arrangement of body posture: the difficulty of body posture in preliminary provision is moderate,the difficulty of single movement body posture is distribute in 0.2-0.3,complete sets of posture and difficulty distribute in 0.2-0.5,the difficulty of single movement body posture of Gao Lei in our country and Belarus athletes was the highest,followed by Japan and New Zealand athletes,while the difficulty of single movement body posture of the Russian athletes and Dong Dong in our country was lower;the final free posture and difficulty of body is moderate,the difficulty of single movement body posture is distribute in 0-0.3,complete sets of posture and difficulty distribute in 1.7-2.3,posture difficulty of Masaki ITO in Japan was the highest,and the proportion of the pike position was higher than other countries,while in China,Belarus Russia and New Zealand,the posture difficulty were lower.The results show that the body posture arrangement of elite athletes and mostly choose pike position in front,body or pike position in the straight position in the order of a few athletes in complete selection body postures.Body posture was not significantly different among countries.
