Research On The Routine Choreography Of Men's Floor Exercise Complete Set During The Tokyo Olympic Period

Men's floor exercise is a traditional single event in gymnastics,which plays an active role and plays an important role in the development of competitive gymnastics.From 1980,"Prince of gymnastics" Li Ning,Li Yuejiu,Tong Fei,Lou Yun and Li Xiaopeng were born one after another,and then to London's "Hardware King" Zou Kai,all of which reflected the international status of China's competitive gymnastics.However,as a single event of competitive gymnastics,floor exercise has lost its previous superior position in the last two cycles,which shows that the advantages of floor exercise in China are gradually declining.By studying the arrangement characteristics of athletes' complete sets of movements in the finals of the three World Championships in the Tokyo Olympic cycle,this paper understands and discusses the development law of the complete sets of movements of floor exercise.In-depth understanding and research of the new rules and movement structure will provide theoretical support for the study of athletes' complete set of movement arrangement characteristics in the new cycle.Through the methods of literature review,video observation,mathematical statistics and comparative analysis,this paper analyzes the 25 sets of complete sets of movements in the individual finals of the 47th,48th and 49th World Gymnastics Championships in terms of type,structure,difficulty and completion quality,and draws the following conclusions:1.according to the new rules,the men's floor exercise group was merged and changed from 4 groups in the previous cycle to 3 groups now,and the original group iv was merged into group ii and group iii,and the score of each group was reduced from 2.5 to 2.0.In addition,the connection bonus can only be obtained twice in the complete set of actions,that is,the connection bonus is 0.2+0.2=0.4 at most2.There is a new development trend in the changes of D scores and the structural features of complete sets of movements of athletes in the new cycle.2.The opening action mainly adopts a single difficult action,and a few athletes adopt the form of action two connection.In the middle string,the connection of three skill strings,one non-skill and one single skill action are the main ones.The end movement is mainly 1080 degrees after the difficult movement in Group D,and a few athletes turn 360 degrees after two weeks3.With the improvement of "D" score in the new cycle,there is almost no room for improvement in action groups and connection bonus points,so it is necessary to work hard from the difficulty of a single technical action.In the three World Championships in the new cycle,the gap of D scores among athletes gradually narrowed,from 1.3 to 1.1 and then to 0.4,and the average value of D scores was from 6.350 to 6.133 and then to 6.263,showing a trend of first decreasing and then increasing,while the average value of E scores was gradually increasing.4.Non-skill movements are mainly to meet the needs of groups and enable athletes to quickly adjust their own state.Among them,the Russian-style stand-up swivel 1080 and the Japanese handstand 2s from the split leg sitting and pressing are hot selection actions;Forward skill movements are the main body of the whole set of movements.Among them,straight front 360,straight front 720 and straight front 900 are the first choice for connecting with other actions.Backward skill movements can observe one's body posture during somersault and swivel,which is convenient for athletes to master.Among them,straight back 1080,two-week rotation 720 is the standard for athletes,and straight back 1440 is the gold stroke.Because of the change of new rules,most athletes use 0.2+0.1 connection bonus points.5.In the new cycle,it is necessary for athletes to get excellent results not only from the D and E points,the innovation of complete sets of movements,the adaptation of new rules and the excellent scientific team support,but also as an indispensable part of the road to winning gold.6.Chinese athletes need to improve the difficulty score and the connection score in the complete set of movements,and continue to maintain the completion quality of the complete set of movements on the basis of strengthening the difficulty value of D score.
