Choreography Features Research Of Collaborations Difficulty In Group Event Of Rhythmic Gymnastics In China

At present,the rhythmic gymnastics is to be violent competition pattern,to find out the reasons that hinder the development of group events in China is an urgent problem to be solved.The essence of the group event is to use the tacit cooperation between the five athletes to reflect the cooperative spirit of the group event.The collaborations difficulty is the most typical feature of the collective action of the group event.Therefore,the grade of the complete set of movements for the rhythmic gymnastics group event is mainly determined by the collaborations difficulty of the arrangement,and it is bound to focus on becoming the key to this cycle of research,and it is also the key to the top of the group event.With a 2017-2020 edition of the international rhythmic gymnastics group event code of points for the new guide,using literature review,video analysis,mathematical statistics and other research methods,resolution 2019 national rhythmic gymnastics collective championship 11 teams,a total of 22 sets of actions including "3 hoops + 4 clubs " and "5 balls" are the starting points for the collaborations type,scores,expressions,and quality of completion.The in-depth analysis of the orchestration characteristics of their collaboration difficulties is sought to find the deficiencies of the orchestration and to be clear.The current development trend of rhythmic gymnastics of group event.is aimed at improving the overall level of Chinese rhythmic gymnastics of group event,proposing a layout strategy suitable for Chinese rhythmic gymnastics of group event,and laying a solid foundation for improving the international status of rhythmic gymnastics of group event in China in the futureThe result showed that(1)The types of collaborations difficulty selection of rhythmic gymnastics group projects in "3 hoops + 4 clubs " and "5 balls" are not creative according to the apparatus characteristics of the project,too much focus on 1-2 types of collaborations,resulting in uneven selection of collaborations difficulty types,There is an obvious lack of class phenomenon,unable to show the diversity of athletes and apparatus space use,which greatly affects the space artistic effect of the complete set of movements.(2)The main scores of "3 hoops + 4 clubs " and "5 balls" are based on the same type of collaborations.The increase in the number of additional criteria will increase the overall score of the difficulty of collaboration,making the overall value of "5 balls" significantly higher than "3 hoops + 4 clubs ",also reflects that athletes use one apparatus technical is significantly better than two apparatus.(3)The expression form of collaborations difficulty type does not consider the apparatus characteristics of two different group exercises,and uses the "synchronization,chorus,cannon and contrast" arranged by the cooperation organization of group exercises to better reflect the flexible and diverse creative forms of each collaborations type.And finally,the lack of the diversity of the forms of expression of collaborations difficulty affects the aesthetic space of the whole set of actions.(4)"3 hoops + 4 clubs " and "5 balls" the single type of collaborations difficulty selection and arrangement,the cooperation organization and arrangement form between athletes,athletes and apparatus,and between apparatus and apparatus are lack of creativity of project characteristics,which reduces the artistic value of a complete set of actions.During the completion of collaborations difficulty,due to the instability of throw joint,there are some phenomena such as grab joint,no hands,no additional standards outside the line of sight,and the equipment is still,which reduces the completion quality of collaborations difficulty,directly affects the final score of complete set of actions.
