Research On The Difficulty Movement Of Group C In Competitive Aerobics Single Project

Competitive aerobics is in rapid development phase, the difficulty movement is an important part of the competitive aerobics, and group C difficulty movement accounts for almost half of the complete set of difficult moves. Group C difficulty movement difficulty of its quantity, type, value, distribution, combination of the technology level of relationship with a complete set of movements and the overall quality, are the coaches and athletes have been the focus of attention.This article selects the method of documentation, expert interviews, video analysis and mathematical statistics research methods, such as Clear rules of competitive aerobics group C 2009 edition with 2013 edition difficulty movement of change, Technology basic structure and types, the thorough analysis of men’s singles, women’s singles group C project difficulty movement in the 12 th and 13 th session of world gymnastics championship, the application of characteristic, And accordingly, in order to coach group C difficulty movement in the 2013 edition rules of the contest have a deeper understanding, At the same time hope to provide reference for our country athletes training and complete sets of movements. Research conclusions and recommendations are as follows:1)Group C difficulty root named grouping to rectify. Delete some of the same as the same category difficulty movement of total degree, the action of single and not used for a long time action. 1 score increased slightly, the other are reduced.2)Group C difficulty movement technical types are divided into simple, compound, combination difficulty movement. Simple has a tendency to phase out; Composite tends to be more difficult; Combination forms, there are Seven ways to achieve only five.3)Difficulty of using the group C than the previous slightly reduced, in accordance with the principal component in the difficulty of a complete set of movements. Two tournament single project group C difficulty movement of choice is not balanced, and the 13 th is more outstanding, to the class, tamar, exchange of legs are no use. Biggest difference with the previous game is: men’s singles completely abandoned and jumped, horizontal split leg, longitudinal split legs jump, women’s singles deprecated and dance class. 4)The decrease in the number of group C difficulty movement mainly value difficult movements, two contest value difficult movements men’s singles are more than women’s choice, and women’s singles to reduce the number of is more than the men’s singles to reduce. To the athlete’s physical stamina and technical ability put forward higher request, to the direction of a hard development.5)Two-times world single project the most difficulty in the distribution of group C, the number of men’s singles, women’s value difficult movements is always passive, before the men’s singles, middle freeboard difficulty value quantity increasing by piecewise decline into piecewise. Compared to the 12 th and 13 th front increase women’s singles, and, after a period of decrease in men’s singles, before while, after reduction to increase, the male athlete physical ability put forward higher requirements.6)Two single project group C game difficulty movement on the site use, the highest rate of shift upward, and the left corner, by the center to develop in the direction of equalization. Three-dimensional space group C difficulty increase in the number of the development in the direction of the ornamental more powerful.7)C- A, C-C are the two main combination form of the game, C- A difficulty difficulty types before and after the combination of the lack of diversity, but before the difficulty in the direction of the "new" development. The 13 th world championships C- C difficulty combination number is increased, the type less. To break through the C- C combinations, must improve athletes lower limb strength and explosive force.8)Suggestions: under the condition of ensure "stable", break the imbalance of the root application named groups; Creating a new difficulty combination type, try to try to connect the three combinations. Improve the C- B, C- D, D- C combination form of utility ratio, increase the diversity of difficulty combination. C- A difficult combination connection difficulty action not only limited to carry buttock after class, increase the difficulty choosing the type of group A.
