Research On The Gymnastics Aerobics Difficulty Movement Change And Practice Interaction Under The Rules

Each rule change will result in a technical change to the aerobics the difficulty selection situation represents the technical level of competitive aerobics, the development of technology promotes the scoring rules, and perfect scoring rules and promote technical difficulty movement toward a higher level. Therefore in the scoring rules comes as the2013-2016cycle of Competitive Aerobics difficulty movement for change, old and new rules in the analysis, combined with the use of games in the world championships and the difficulty in practice.Based on Research on the Gymnastics Aerobics difficulty movement change and practice interaction under the rules as the core research content, using video analysis and mathematical statistics, from the difficulty quantity, value, other aspects of FIG2009-2012, FIG2013-2016rules difficulty movement for changes in the specific circumstances, and by the11th、12th World Aerobics Championships,2013ninth session of the world games in the final set movement of the use of quantitative analysis and verification. which discovered the interactive relationship between difficulty movement rule changes and practice.The results of the research show that:1)The world championships, the difficulty of0.7-0.8score with the largest number,13edition rules of0.1-0.2reduced to88difficulty movement09edition rules in processing, games, the most difficulty score to0.6-0.7points, of which70%difficulty movement from the score in version09of0.7-0.8action.2)World Championships application rate of Cape class action0%is deleted, in the13edition rules in the application rate of more than100%of the Straddle Support and L-Support with SUPOORT FAMILY;Tuck and Cossack merged into BENT LEG(S) JUMP FAMILY;Split jump、Switch Split leap and Scissors leap into SPLIT JUMP FAMILY. 3)Under the new rules, the Individual men、Trio and Group projects A, B, C, D difficulty selection of proportion of2:1:5:2in the games as athletes "standard"; the Individual women world project each difficulty action selection in proportion of2:1:5:2, the World Games is to rewrite2:1:4:3.4)FIG2009-2012rules of Trio female athletes to participate in Group action and item difficulty index was adjusted, but three people consisting of female athletes in the world championship and the group of only9, accounting for28.125%of the total,13edition rules,1.9point index is further reduced to1.8, the in the three women’s gymnastics team composed of a substantial increase, accounting for50%of the total number of teams.
