Research On The Development Of Difficult Movements Of Competitive Aerobics Under The Rule Of FIG

With the vigorous development of competitive aerobics,the differences in the sports level among top players in the world are declining,and the competitiveness is becoming fiercer;while competition is intensifying and moving forward in the direction of "difficulty,novelty,beauty,stability and accuracy".In order to enhance the competition ability of the players,choosing difficult pattern to get high score is the key to win the game.Therefore,the contestants have to increase difficulty in competition routines,create connection points and expand the difficult choice of wide variety,balance,creativity,continue to challenge the limits so that they can obtain excellent results and higher score within the competition rules scope.From the first issued edition of FIG rules in 1994 till now,there are 6 versions of the FIG rules and each version of the rules will be modified on the difficulty of action to a higher demand,affecting the players and coaches to create routines select patterns,thus affecting the development of difficult moves.By reviewing the literature,it is found that the problems related to the rules and difficulties of competitive aerobics have always been the focus of the field of competitive aerobics.However,the relevant research is mainly about the comparison of old and new rules and the analysis of difficulty itself.Research on difficult action development is rare which an urgent problem to explore.This paper compares and expounds the rules of 2009 and 2013 from the aspects of number,group,change of scores,difficulty connection and so on through the literature,interview,video observation,mathematical statistics and comparative analysis,and combined the four world championships in the first five rounds of the difficulty use to summarize the calculation under the period within the two rules.Gathering the difficulty selection of routines from full range of high-level players and then comparing advantages and gaps exist among our country and other countries in the choice of difficulty is aimed to find out the reasons and solutions for the promotion of China's technical standards and the pursuit of world power while put up constructive comments.The research shows that:1.Difficult pattern is the essence of competitive aerobics.With the continuous revision of the rules,enhancement of athletes from physical quality to technical level,higher scores with difficulty are in great numbers;our players on the scope of 0.8-0.9 score of difficulty have to continue the strength training.2.Classification of Difficulty is becoming more standard,appropriate,clear,resulting in a standardized system of difficulty.Single group in the use of difficulty are mainly based on the C group,which is the strength of our athletes and need to continue to adhere to;and B group difficulty is the weak link of all athletes;A group of difficulty is weakness in our country and must be targeted to adjust and strengthen the training;D group is the trend of difficulty development while male players have to be strengthened on flexibility and balance.3.The current contestants use single difficulty of connecting and many teams re-use the same difficulty to connect which lack innovation and hard to get high marks in competition.The use of difficulty connection challenges coaches and athletes to create a new combination of difficulties both encourages them boldly attempt to new difficult connection to promote the difficulty toward the direction of hardness and beauty.4.The new revised rule is about to be introduced and it will produce a series of new changes on the difficulty of action based on the development of current situation.So coaches and athletes should carefully study the old rules and predict practical application before new event,so as to adjust the training arrangements for athletes and avoid lose their head after great changes launched in the new version of the rule.In view of the above conclusions,suggestions are as follows:1.Deeply understand and master the rules,use rules in the maximum scope;2.Continuously strengthen the physical fitness of athletes and special skills training;3.Focus on the innovation of connection difficulty.
