An Action Research Of Collective Item Difficulty Under The Rules Of Competitive Aerobics Competition Of FIG 2013-2016 Version

Competitive Aerobics project originated in traditional aerobic exercise,Is in the accompaniment of music,Able to demonstrate continuous, complex, high-intensity sets of action sports ability.With the competitive aerobics exercise project development and continuously improve the technical level of athletes,Competitive aerobics competition rules to update a cycle every four years,Competition Rules Changes and adjustments directly to shape the direction of the project.Competitive Aerobics difficulty movement is an important part of a complete set,It is also an important factor to obtain the outstanding game scores and display of Athletic Competitive Ability.Aerobics collective project has high ornamental and competitive,From 2006 the ninth session of the World Sports Aerobics Championships in2012 twelfth session of the World Sports Aerobics Championships,China's competitive aerobics collective project with complete selection of high difficulty and high quality has been in a leading position in the world,But in 2014 the thirteenth session of the World Sports Aerobics Championships in our collective project only gained third.The new rules of Competitive Aerobics difficulty movement in a new direction,Through the change of the competitive aerobics competition rules as well as the research of nearly two World Aerobics difficulty movement collective project Championship,To find out the advantages and disadvantages of Aerobics difficulty movement collective project in our country athletics,For China's competitive aerobics collective project toward a more stable, more direction to provide theory basis for the development,At the same time, also provide a useful reference for our sports aerobics collective project training and competition.In this paper, using the method of literature, expert interviews, video observation,comparative analysis and mathematical statistics,After comparing and analyzing the recent two edition of Competitive Aerobics difficulty movement in the contest rule change,At the same time to hold this period under the two aerobics collective project comparative analysis of world championship before the three sets of difficulty movement,The future forecast the development trend of Competitive Aerobics difficulty movement,To explore the methods and Strategies of improvement.Research results:1.The selection of Competitive Aerobics difficulty movement under the new rules become more difficult,The difficulty of the completion of an action become more demanding,The difficulty movement will be towards a more scientific, reasonable development direction,Aerobics Competition has become more humane, more equitable.2.The difficulty movement in the new rules "to get rid of the stale and take in the fresh" Reflects the competitive aerobics advancing with the times and innovation characteristics,Also shows that always toward become an official event of the Olympics in the direction of the development continuously competitive aerobics.3.Changes in the rules of Competitive Aerobics collective project has entered a new stage, Collective project must show a group is superior to the single project ornamental property and artistry.4.Complete the collective difficulty movement level of our country tends to be stable,The lack of diversity and innovation in the selection and arrangement of difficulty elements.5.Collective difficulty movement in China group selection is not balanced, a single score gap is larger and type selection of difficult movements;The difficulty of movement space shift to a more balanced, smooth, difficulty score rate increased.6.The future movement difficulty of Aerobics collective project to ensure that technology and complete the "beauty" and "steady" on the basis,Efforts to pursue the difficulty action selection and arrangement of the "hard" and "new",At the same time towards high difficulty in competing with unique artistic combination of direction.
