A Study On The Application Of Technical Skills In The Collective Jazz Events Of The Recent Three World Cheerleading Championships

The Cheerleading World Championship is the highest level Cheerleading event in the world.It is held every April in Orlando,USA.Due to the cheerleading project started late in China,there is a certain gap between the technical level of China’s cheerleading and some developed countries,especially the cheerleading team jazz project in the world championship competition results are not ideal.But with the more and more national attention to the cheerleading project,our country in the collective jazz project to achieve excellent results on the goal becomes particularly important.In international rules,technical skills is one of the important content in the ratings,and want to further improve the results in our country,should learn from foreign outstanding team,on the basis of experience in technical skill moves the plait,efforts to promote our country collective Jazz cheerleading the difficulty of the action skills and technology innovation,and form their own unique style of complete sets of movements.In this paper,the method of literature,video analysis,expert interview,mathematical statistics and comparative analysis as the research method,under the guidance of the international version of the rules,the application of technical skills in the recent three Cheerleading World Championships collective jazz project as the research object,By comparing and analyzing the top three technical skills of the collective jazz group and the technical skills of the Chinese team(2017,2019)in the Cheerleading World Championships from2017 to 2019,a total of 11 sets of movements are carried out to find the rules and advantages of the excellent teams in the application of technical skills from the three aspects of type application,space application and the application of completion form,This paper analyzes the deficiencies and reasons of our team,and puts forward the corresponding development countermeasure,which provides a reference for the arrangement and the application of technical skills of collective jazz cheerleading in our country.The results are as follows:1.Technical skills and movements have the following development trends in the application of collective jazz events in the last three Cheerleading World Championships:(1)“2017-2020 Cycle Cheerleading Competition Rules” removed the old rules of the technical skills of the grade division,which means that it can fully stimulate the innovation consciousness of each team,so as to improve the diversity and innovation of technical skills.(2)The ranking of the use times of the three kinds of technical skills is the rotation type>jump type>balance and flexibility type>writhe movement>lift and match movements.The single swivel is dominated by sucking leg swivel,while the compound swivel is transformed into innovative,diverse and complex movements.The jumping class develops into the moving,reflexive,swapping leg class;The use value of balance and flexibility has been greatly reduced,and it has evolved into the other two types of difficulty movements.The somersault movement developed from the back soft somersault to the side somersault.Lifting and coordinating movements evolved into modelling movements with artistic conception and story.(3)Difficulty moves move towards three-dimensional space,realizing smooth switching of multiple Spaces;Wriggle action appears the superposition use of level space;Lifting and coordinating movements create a multi-level spatial B-C connection.(4)The number of partial completion forms takes the highest proportion in the difficulty movements and the writhing movements,followed by the individual completion forms,and finally the collective completion forms.Therefore,the arrangement of partial completion forms should be emphasized.The use value of single group of lifting and coordinated action remains unchanged,while the value of multiple groups of lifting increases.Therefore,the arrangement of multiple groups of lifting should be appropriately increased.2.The deficiencies of Chinese team cheerleading collective jazz in technical skills:(1)The technical skills of the movements are not standard enough and the quality of completion is poor.(2)The number of technical and technical movements is small,and the difficulty coefficient is not high.(3)Lack of innovation in the application of technical skills and movements and failure to highlight highlights.3.Put forward the development countermeasures of Chinese team cheerleading collective jazz in technical skills:(1)Improve the standardization of technology and pay attention to the high quality completion of technical skills.(2)Increase the number of technical skills,flexible innovation of a complete set of technical skills.(3)Strengthen the construction of teaching staff and enhance the ability of technological skills and movement innovation.
