A Comparative Study Of Technical Movement Between Chinese And Foreign Team Cheer Jazz

In recent years,with the rapid development of China's economy and the acceleration of social footsteps,various kinds of sports have repeatedly achieved good results in international competitions.The vigorous development of cheerleading has led to the participation and support of people of all ages in China.The Chinese team has also appeared in international competitions for cheerleading.The distribution and completion of technical movements in team cheer jazz in recent international competitions have restricted the scores of complete sets of cheerleading exercises.At the same time,China has a certain gap with other high-level countries in terms of the completion quality of technical actions and the distribution of action connections.Based on the overall improvement of China's team cheer jazz technical actions,I intend to use the literature data method,video observation method,expert interview method and mathematical statistical method,set the complete set of action videos of the top eight teams and the Chinese team in the 2019 World Cheerleading Championship National Cup Jazz Lala as the research object,and the "2017-2020 cycle cheerleading competition rules" are used as the guidelines to study from the three aspects of jazz cheerleading technical actions.Concluded as follow:1)The total number of difficult movements of China's cheer jazz ranked eighth among the participating teams.The number of completed actions of large groups was equal to that of other countries,while the number of completed actions of small groups was less.Among them,the jump class has the most difficulty quantities,and the turn class has the least difficulty quantities with relatively low completion quality,and the lack of high-difficulty connections leads to a single combination form.The United States team and the Japanese team have a greater advantage in the overall number of difficulties,various difficulty combinations in various forms,with distinct levels and high completion quality.2)The technical characteristics of jazz are mainly embodied in the sense of extension of body movement from the inside out,that is,through the extension of braking,control of movement,movement continuity to achieve the specific dance aesthetic of team cheer jazz.This aesthetic feeling of the whole movement of our team is relatively low,and the problem of inconsistent movement orientation in different spatial planes has occurred,which did not make the referees feel a strong visual impact.With the change of music rhythm,dance movements of other high-level teams also change accordingly,so that people can feel the corresponding atmosphere through dance movements in different musical backgrounds.As of China,the consistency of dance movements,the overall control of the body and the reasonable use of the spatial hierarchy of dance movements need to be improved.3)China's competition melody is relatively light and lively,but the overall lack of ups and downs.The overall strength of the players' movements is weak.Due to the athletes' physical fitness and music frequency,the physical strength of the athletes in the latter half of the complete set of movements declines rapidly,and the control of the movements weakens,which makes it impossible to achieve the due movement specification.The American and Japanese teams have chosen music with big ups and downs in melody and clear rhythm.The overall movements blend with the music emotion,and the strong movements can better complete the routine of the competition.Through the analysis of the present study,we can see that there is still a certain gap between the overall level of China's team cheer jazz and foreign high-level sports team.in the future training process,it is necessary to strengthen the physical fitness training of athletes system,raise the difficulty of competition routines,and enhance the cognition of dance moves and dance training.At the same time,coaches should constantly improve their professional quality,and gradually integrate with the world in terms of training methods and other aspects,so as to narrow the gap between China's team cheer jazz and foreign strong teams.
