Research On The Element Combinations In Complete Sets Of Gymnastics Aerobics Collective Project

The appearance of difficulty combination makes competitive aerobics develop towards high difficulty and high art.As the world competitive aerobics competition is becoming more and more intense,the difficulty combination has become a magic weapon for each country to improve its competitiveness.It has become an indispensable part of the competition.From the present research content of competitive aerobics,the world is about the world.There is less research on the difficulty combination,so it has certain significance for the study of the difficulty combination in the world competition.This paper,based on the "study of the combined movements of the collective action of the competitive aerobics group,",through the literature,interview,video analysis and mathematical statistics,takes the first eight in the 2014 World Championships and the 2016 World Championships,and the 2017 World Games aerobics events of six.The difficulty combination used in the complete set of teams is the research object,and the type of difficulty combination,the name of the root,the change of space,the value of the risk,and the degree of risk are studied to provide the theoretical basis for the more scientific application of difficulty combination in our country's collective projects in the future.Research conclusions1.The number of double difficulty combination in the three world competition shows a trend of growth and decline.In 2016,the difficulty combination of the world championships increased obviously.The use of the three connection made the number of the 2017 world games less difficult than the 2016 World Championships.2.The ratios of C-A combination and C-C combination in 2014 and 2016 tournaments were 66.7% and 33.3% respectively,and the difficulty combination of the world games in 2017 was three connected to C-C-A,and all the skill movements were backhanded.3.The difficulty combination of the three world competition group C group is the most difficult to use,the A group difficulty to lift the buttock class,the cutting class in the Trio use the most,the overall three collective projects,the difficulty combination of the difficulty of the use of a small difference.4.The degree of degree of saturation of difficulty combination in the three world competition shows a trend of decline and growth of three items.Among the different collective projects,the degree of saturation of the difficulty combination of Trio is obviously higher than that of the Group and the Mixed Pair.The degree of saturation of the difficulty combination of the Group is slightly higher than that of the Mixed Pair exercise,and the two items are more all.The situation of the balance.5.The proportion of the three world competition difficulty combinations in the front,the middle and the rear sections of the complete set of movements is 60.9%,29.3%,and 9.8%,showing the characteristics of the difficult combination,which is more obvious in 2017 than the first two games.6.The difficulty combination of the two World Championships in 2014 and 2016 was dominated by the difficulty combination of jumping + pushing up the class and the difficulty of jumping and jumping class.In 2017,the difficulty combination of the World Games was dominated by jumping,jumping and pushing.7.The average of the risk degree of the single difficulty combination of the three projects is the lowest of the Mixed Pairs exercise,and the three exercise is the same as the Group.The risk degree of the combination of the Mixed Pair exercises is smaller than that of the two difficulty combination.The first difficulty combination is slightly lower than the second difficulty combination,and the difference of the risk degree of the two difficulty combination of the three and the Group are quite different.The risk score of the first difficulty combination is significantly higher than the risk score of the second difficulty combination.
