The 2017 World All-Star Cheerleading Competition Jazz Open Mixed Group Difficulty Action Arrangement And Application Analysis

The Jazz Cheerleading set is composed of different types of jazz style dance movements,formation changes,group matches,and difficult movements.Difficult movement is an important part of the Jazz Cheerleading.The difficulty movement arrangement reflects the whole team.Level.The development of Chinese jazz cheerleaders is still in the preliminary stage.Therefore,there is still a big gap between the arrangement of complete sets of actions and the use of difficult movements and the outstanding teams in the world.The paper uses the literature,video analysis,mathematical statistics,and comparative analysis methods to use the overall arrangement of difficulty movements and different types of difficulty in the first eight teams in the open-mixed jazz group of the 2017 All-Star Cheerleading World Championships.Conduct an analysis to find out the shortcomings of Chinese jazz cheerleaders in difficulty movements,and explore reasonable methods for the arrangement of difficulty movements.This will provide constructive suggestions for improving the overall level of Chinese jazz cheerleaders and narrowing the gap between them and the world's outstanding teams.The study yielded the following results:1.In the arrangement of difficult difficulty movements,the number of difficulty levels cannot determine the overall level of the team.A balanced distribution of the number of difficult movements before and after the first half is more conducive to the completion of difficult movements and high quality;in terms of difficulty type,individual jumping steps account for difficult movements.With a single difficulty level of 44%,the rotational difficulty movement has a high application value in the combinatorial difficulty arrangement.The combination of difficult teams in the world's excellent teams is diverse,and the Chinese combination has only appeared twice in difficulty,and the difficulty moves lacks innovation.The collective difficulty layout reflects the overall level of the team,the number is only the foundation,focusing on the collective difficulty to complete the quality and consistency is the key.2.In the step-by-step difficulty type arrangement,the type arrangement is more diverse,and the number of step-by-step jumping difficulties>the number of step-by-step jumping difficulties>the difficulty number of jumping in place.Jumping between marches accounted for 90%of the difficulty in jumping between moves,and 50%of reflexive jumps in reflexive jumps.It can be seen that the cross-jump difficulty movement with large displacement changes is the focus of the difficulty movement arrangement of the Jazz Cheerleading.In the difficulty category of Swivel,most of the teams are mainly turned into rotations,and Aramaic C-bar composite swivels are assisted in the arrangement of difficulty in turning.Among them,the types of difficulty movements in the legislation category are not balanced,the flexibility transition only accounts for 19%of the difficulty level,and 62%of the rotation turns to be less than three weeks in small groups.The excellent teams in the world pay more attention to the arrangement of the individual's difficult movements.The diversity of movements in combination with Allah C-bars is difficult,while the types of difficulty in China's diversions are single,and the number is small.There is a big gap with the world's outstanding teams.In balance and flexibility difficulty movements,difficulty types are balanced and balanced.The difficulty movement arrangement with the flexibility class focuses on the collective accomplishment,while the static class balance and the flexibility difficulty movement arrangement are mostly completed in individual and small collective forms.3.Difficulty moves in the formation changes in the form of small group and individual jumping difficulty class formation adjustment,giving people to stimulate the visual experience,to adjust the stage layout with the overall mobile formation,giving a strong stage effect,in the application of the comparative combination of actions In the middle,the difficulty level promotes continuous visual impact,and the difficulty movement is combined with the multi-layered space to enhance the visual impact of difficulty movements;uneven difficulty rhythm,long duration of competition,and The difficulty movement arrangement that does not match the athletic quality is the main reason that affects the difficulty application effect.
