The Arrangement Characteristics Of The Preliminary Contest Of The Excellent Female Trampoline Athlete In The Four Factors

The trampoline project was officially established by the IOC in 1997 and became the official competition for the 27 th Sydney Olympics in 2000.There are two individual gold medals for men and women online.There are two individual gold medals for men and women online.The choreography of an integrated set of actions must accord with variations in the scoring regulations with the cyclical variation of the scoring rules of the competitive trampoline project.The trampoline competition preliminaries consist of two sets of moves.Their performance determines whether the athletes can enter the semi-finals or the finals.At the same time,the preliminaries also determine the qualifications of each unit group and individual competition.Therefore,the arrangement of the two sets of pre-qualifying games is highly valued by coaches and athletes.The IIF stipulates that if there are two players in a country who access the top eight at the World Championships at the same time,and one of them must enter the top four,they can get two seats in the Olympic Games the next year,so the preliminaries are particularly crucial and important.Therefore,it is the lumping significance to indicate the arrangement characteristics of the pre-match action of the outstanding female trampoline in China in light of the variations in the scoring regulations at the initiating of the fresh Olympic cycle.In this paper,four scoring factors and distribution of the Preliminary Action were analyzed through the method of literature,expert interview,video analysis,mathematics and physical statistics,comparative analysis with the change of the international trampoline rules from 2017 to 2020 and the women’s preliminaries action(292 sets)of the three trampoline competitions in 2017 are researched.So as to fully understand the arrangement features of the pre-match action of the brillant female trampoline athlete in the four factors,to find out the factors that influence the choreography of the preliminaries and put forward some reasonable suggestions.The aim is to improve the layout of our women’s trampoline athletes so that they are not controversial in their arrangement.These are the theoretical basis for the women’s trampoline athletes in a complete set of choreography of preliminary and improve the level of the women’s trampoline athletes.The conclusions are as follows:(1)There are two major changes in trampoline scoring rules from 2017 to 2020,firstly,based on the original scoring system(three assessment factors),the horizontal displacement score(10 points)was increased,at the same time,the quality of actions score of the complete set was reduced from 30 points to 20 points;secondly,it doubled the number of difficult movements in the first set of the heats,gaining the hardness value of the previous two actions to the hardness worth of the four actions.Therefore,it is necessary to make corresponding adjustments in the layout of the complete set of actions.(2)It was found that the average of the first eight difficulty values of the preliminaries was 2.775 before the new rules are implemented,the average of the eight previous trials was 4.633 after the new rules are implemented by comparing the preliminaries performance of the first eight athletes of women in the trampoline competition before and after the implementation of the new rules of 2017~2020,although the number of hardness moves doubled,the hardness value didn’t increase.This shows that the first set of actions is still to survive with quality,and in the arrangement of the first set of actions,we cannot blindly pursue high difficulty.(3)The technical scores,difficulty scores,height scores and horizontal displacement scores of the first set of preliminaries should be competitive after 17.7,4.8,16.690 and 9.6.There are two modes for the choreography of the first set of the preliminaries of the excellent female trampoline in China,one pattern is the choreography of the elastic movement of the belly and backside and the other pattern is the choreography without the elastic movement of the abdomen and back.There are three types of the choreography of the elastic movement of the abdomen and back: The first one is to arrange the elastic movement of the abdomen and backside to finish actions and the center and end positions are arranged with two difficulty actions;The second is to arrange the abdominal movements at the beginning of the complete set of movements,and to finish the four movements that are difficult to make calculations at the end position,and to arrange a one-week overturn movement at the remaining positions.Thirdly,four difficulty movements are arranged in the starting position of the complete set to calculate the difficulty value of the complete set of movements,the elastic action of the belly and backside is placed at the end.There are two patterns of arrangement without elastic movement of the abdomen and back.First,arrange 4 difficult movements at the beginning and the end of a single week action.At the beginning and the end of the complete set of actions,two hardness actions are arranged to count the hardness value,arrange a one-week flip in the middle.These two species of arrangement types have their own characteristics and should be selected according to the characteristics of Chinese women trampoline athletes.(4)The technical points,difficulty points,height points and horizontal displacement points of the second set of preliminaries should be competitive after 16.0,14.4,15.895 and 9.5.There are two types of choreography of the second set of preliminary,one is to arrange the difficult three weeks of somersaults in the starting position of the complete set of movements,two weeks of somersaults in the middle,the back flip of the straight body is two weeks of the degree of transformation is large at the end(822 /).The difficult three-week flip in the first and third position of the complete set of actions,to choreograph two weeks of somersaults in other positions,the back flip of the straight body is two weeks of the degree of transformation is large at the end(822 /).Suggestion: In the preparation of the first set of action in the preliminary game,the quality of the action should be taken as the main focus,and high-quality movements with a certain degree of difficulty should be arranged to ensure the stability of the movement so as to smoothly enter the finals. In order to reduce the demerit points of the first set of moves in the preliminaries or keep them at a higher level,the views may be remarked in the course of the actions: 30 /,50 O,40 O,40 <,40 / deduction points less action,and our athletes have a higher level of mastery,should be used in the first set of actions;front flip over one turn in 180 ° movement 41 O,41 /.There is a demerit point,which should be selected and used according to the type and characteristics of the athlete’s skill;in our country,athletes turn and turn 180° in front of a squat body,and 41 < points are more deducted.It is recommended that they be avoided in the first set of moves.In the second set of preliminaries,China’s women’s trampoline athletes need to achieve a balanced development in terms of quality,difficulty,high altitude and horizontal displacement.The arrangement of the complete set of moves must meet the technical characteristics of the athletes in order to better display their personal advantages.
