A Comparative Study On The Difficulty Values Of The Exercises Of Foreign Excellent Rhythmic Gymnastics Teams And Chinese Teams

This study is a comparative analysis of the number,type and bonus factors of various types of difficult exercises in the top six teams of the 2017-2019 World Rhythmic Gymnastics Championships and the Chinese team’s complete sets of movements to find out the Chinese team’s artistic gymnastics collective items in the complete set of difficult exercises The gap between the top six teams and the top six teams;after analyzing and comparing the 2017-2020 version of the international scoring rules,according to the analysis results,suggestions for the arrangement of the set of difficult exercises are proposed.This article uses the literature data method,video analysis method,mathematical statistics method and comparative analysis method to study the 42 sets of exercises of the top six teams and the Chinese team of the 2017-2019 World Artistic Gymnastics World Championships collective all-around finals.(1)In the 2017-2019 World Rhythmic Gymnastics Championships group event,the top six teams and the Chinese team have different points in the set of difficulty exercises.The top six teams and the Chinese team arrange the number and points in the balance exercises of physical difficulty.The value is higher,and the number of arrangements is less in the rotation difficulty and the jump difficulty,but the score is relatively high.The Chinese team needs to improve the quality of the physical difficulty compared to the top six teams.(2)In the 2017-2019 World Championships,the top six teams make full use of the fundamental technical groups and the non-fundamental technical groups in the choreography combination.The top six teams occupy the dominant position in the fundamental technical groups.Artistic style characteristics.The Chinese team uses relatively few fundamental and Non-fundamental technical groups in dance steps.The gap between the Chinese team and the top six teams in the number of dance combinations is relatively small.(3)In the arrangement of the exchange difficulty between the top six teams and the Chinese team in the 2017-2019 World Championships,the Chinese team used fewer exchanges and additional standards in the exchange difficulty than the top six teams,so the exchange difficulty score was relatively low However,the top six teams have a higher exchange difficulty score,more types and numbers of additional standards,and the addition of diversification exercises also makes the whole set of art expressive.(4)In the 2017-2019 Rhythmic Gymnastics World Championships collective team,the top six teams and the Chinese team are in dynamic elements with rotation.Compared with the top six teams,the Chinese team is more thrilling in throwing equipment and uses additional standard numbers in throwing and receiving.There are many types and types,and the number of rotations and additional standards are used more in the process of dynamic elements with rotation.The Chinese team should combine the characteristics of different device types in the collaborative creation to improve the use of collaboration types and numbers and make full use of the additional standards.To increase the score of collaborative exercises.(5)In the 2017-2019 World Rhythmic Gymnastics Championships,the top six teams and the Chinese team have a certain gap in collaboration.Collaboration is a manifestation of the cooperation between collective athletes and the difference between collective and program for individual gymnasts.More choices in collaboration fully use additional standards to reflect the diversification of difficult exercises.There are many types of collaborations.The types are relatively new and unique.The collaboration is mainly dynamic,while the Chinese team is mainly static.The type is relatively simple and the quantity is few.In the collaboration,the player’s ability to unite is high,and the clever combination of equipment and perfect coordination makes the collective set of exercises show the artistic characteristics.
