Aerobic Difficulty Analysis Through 14^th And 15^th WCH Routine Elements Comparative Guided By Code Of Point

The Code of Point are the direction of competitive sports,which not only restricts the trend of sports technology,but also promotes the development of sports.Difficult Element are the core factors for winning the hard-to-be-competitive group competition,and are the most quantified scoring part of the complete set of movements for the aerobics competition.According to the opponent’s strength and preliminaries,their own set of difficulty adjustments are considered,so that the athlete’s own performance system during the competition process shows a three-dimensional,open,wave,and multi-variable complex control system.How to choose a high score in this complex system Actions and effective avoidance of completion risks through creative skills are the core factors of winning the game.The aerobics competition has 5 individual items for Individual men,Individual women,Mixed Pair,Trio and Group.The rules require different types of difficulty for each individual item to be consistent and different,in order to adapt to other Olympics with the International Sports Federation According to the requirements for the coordinated development of the project,the 2017-2020 Code of Point have made major revisions to the difficulty content.This paper mainly studies the difficulty of 80 sets of actions in the top 8 of each individual final in the fourteen^thand fifteen^thWorld Aerobics Championships under the guidance of the rules of literature,expert interviews,video analysis and mathematical statistics.Perform a statistical analysis of the movements,analyze the characteristics and common characteristics of the individual difficulty movements,and look forward to providing a practical reference for the national team to participate in the final set of difficulty in the final World Championships.Analysis conclusion:1.Two groups of C,A,D,and B of 5 Categories difficulty sets in the two World Aerobics Championships have a decreasing trend in sequence.Among them,the number of difficulty choices in group C（Jumps and Leaps Elements）tends to 5,which is the highest proportion compared with other groups;group A（Dynamic Strength Elements）and group D（Balance and Flexibility Elements）choose to halve;group B（Static Strength Elements）The selection is the least.The minimum difficulty of each individual group B in the fourteen^thsession is basically selected as one.Due to the change in the requirements for group difficulty in the rules,nearly half of the fifteen^thsession did not choose to change the difficulty of the group.2.According to the statistical analysis of the selection of the naming of the difficulty roots of Group C,it is found that the high proportions of the individual items in the two competitions are the three types of scissor jump,flexion and split leg jumping and flexion jumping.Long-legged jump and flexed leg jumps were selected at a high proportion in the fourteen^thWorld Championships.Due to the reduction in the number of difficulty sets for regular Mixed Pair,Trio and Group,nearly half of the fifteen^throunds did not choose this category Difficulty.In the two World Championships,the number of turns of each individual C group difficulty action showed an increasing half-week trend.Due to the change in the requirements of the landing method,the proportion types of the two action spaces（jump type B-C-B and jump type B-C-A）appeared Position(the majority of the fourteen^thWorld Championships are based on the type of jumping station B-C-B).3.In the statistical analysis of the selection of the naming of the difficulty roots of groups A and D,it is found that the two groups of individual A groups have a high proportion of difficulty in push-ups,the middle proportion uses the swing legs,and the support is in the The high proportion of the fifteen^thWorld Championships is selected.Due to the improvement of the scores of the supporting and rising categories by the rules,it is the reason for the increase in the number of complete sets of difficulty.The foot swivel category is selected in a high proportion in the fourteen^thWorld Championships and in the fifteen^thWorld Championships.The rule reduces the difficulty score of the single-foot swivel category.4.The overall selection of the fourteen^thdifficulty combination mainly uses C+A and C+C,two connection types;the overall selection of the fifteen^thindividual difficulty combination type mainly uses two connections C+A and C+C Mainly,the three connections are mainly C+C+A,and the number of difficulty combination types with skill intervention is small;the highest score difficulty combination,the fourteen^thsession is the C+A connection type;the fifteen^thsession is selected C+C+A three connection types.5.The selection of the high score difficulty for the two sessions shows the regular characteristics that Individual men are higher than Individual women and singles are higher than collectives.Among them,Individual men are the highest,followed by Trio and Individual women singles,Mixed Pair and Group are the lowest;The distribution of high-score difficulty actions in the complete set of paragraphs,each single item is the first 1/3 sets,higher than the middle 1/3 sets,and higher than the latter 1/3.The fifteen^thsession of high difficulty score is more reasonable than the fourteen^thsession.Based on the statistical analysis of the 14th Wch and 15th Wch individual difficult movement characteristics,and put forward some suggestions based on the research conclusions obtained in the thesis,I hope that this article can provide practical help to coaches and athletes and provide competitive aerobics for our country.Provide a reference for leading the world.
