A Comparative Study On The Difficulty Elements Of Junior Individual Exercises Of Excellent Chinese And Foreign Rhythmic Gymnastics

On February 1,2018 The International Gymnastics Federation of Rhythmic Gymnastics Technical Committee issued rules and instructions,2017-2020 Code of Points of Rhythmic Gymnastics was revised,the difficulty elements value changed by the full score 10 points for the difficulty elements value uncapped,rhythmic gymnastics junior and senior,more emphasis on the complete set of the difficulty elements to win the ultimate value for individual or group exercises.The key to the overall value of the whole set of movements is to arrange the difficult elements reasonably according to the ability and level of the young gymnasts,so that they can get the highest score within the range of their ability.The research is based on the 2017-2020 Code of Points of Rhythmic Gymnastics(junior group),with the first eight top 64 sets of individual exercises of the First International Sports Federation Rhythmic Gymnastics World Junior Championships in 2019 and the Second China Youth Games Rhythmic Gymnastics Competition(junior group)as the analysis object.Using the method of documentation,expert interview method,video analysis,mathematical statistics,the study both at home and abroad excellent junior individual gymnasts of rhythmic gymnastics complete sets of difficulty elements of the type,quantity,arrangement value and the actual completion,analysis of the overall difference,deeply analyze the junior gymnasts of rhythmic gymnastics difficulty elements to the drawbacks of the technology,for our country rhythmic gymnastics junior individual exercises complete sets of raising the level of difficulty elements and the innovation of the whole action to provide more scientific theoretical reference.Research indicates:1.The difficulty elements value,difficulty elements score and success rate of foreign young gymnasts’ rope,ball,clubs and ribbon equipment are all higher than those of domestic young gymnasts.Therefore,it is the basis and key to improve the score of the whole set of movements to improve the arrangement value and success rate of the difficult elements.2.As a weak sport for junior gymnasts in China,the difficulty of the apparatus of the ball is the type with the largest proportion and difference in average score among the four types of difficulty elements.Although the proportion of the types of difficult elements of Chinese junior gymnasts is higher than that of foreign junior gymnasts,the average score of Chinese junior gymnasts is still lower than that of foreign junior gymnasts,which indicates that the score of individual difficult elements of Chinese junior gymnasts is low.3.Among the types of body difficulty,the balance difficulty is the most commonly used by Chinese junior gymnasts,and the difference in the number,score and number of turns of the rotation difficulty is the main reason that the scores of domestic junior gymnasts are far lower than those of foreign junior gymnasts,which can be regarded as a key breakthrough.4.There is no significant difference in the number and score and the number of the apparatus difficulty combined of dance steps combinations for junior gymnasts at home and abroad.Only by combining the difficult elements with the equipment with high score can we maximize the score of difficult elements with higher score.5.The average number of spins and additional standard scores of each foreign junior gymnast combined with the dynamic elements with rotation are 2 and 0.4 points higher than those of domestic junior gymnasts.Rope,as an instrument with weak dynamic elements with rotation,is different from foreign junior gymnasts because of its lack of quantity,score,number of rotation cycles and additional standard scores.6.Foreign junior gymnasts have opened a gap with domestic junior gymnasts in completing the difficulty of the ball and ribbon equipment with the advantage of quantity.Therefore,the rational use of equipment technology and the in-depth exploration of the characteristics of the equipment have become the key breakthrough point for the improvement of the difficulty level of domestic junior gymnasts.7.Strategies to improve the level of complete sets of difficult elements in individual exercises of Chinese teenagers in rhythmic gymnastics include:1.Excavate the development potential of the complete set of difficult elements of the young people’s individual exercises;2.Do a good job of connecting the technical development of difficult elements in individual exercises for teenagers with that of adults;3.Enhance the creation and editing level of the complete set of difficult elements for the junior individual exercises;4.Learn and use difficult elements techniques and training methods of foreign elite gymnasts for reference.
