Jumping Body Of Artistic Gymnastics Individual Circle Under New Rules Analysis And Development Of Difficult Movements

The development direction of rhythmic gymnastics is determined by the international scoring rules for rhythmic gymnastics.The 2017-2020 edition of the international scoring rules for rhythmic gymnastics modifies the techniques of hoop gymnastics equipment and jumping physical difficulty movements to guide the rhythmic gymnastics to develop in the direction of high difficulty,high value,adventure and innovation.The scoring rules divide the physical difficulty movements into three categories: jumping,twisting and balancing.The jumping physical difficulty movements for rhythmic gymnastics are an important part of the physical difficulty movements for rhythmic gymnastics.This paper takes the jumping body difficult movements of rhythmic gymnastics as the research object,and uses the method of literature to analyze the development and changes of the individual ring exercise equipment technology and jumping body difficult movements in the 2009-2012,2013-2016 and 2017-2020 international scoring rules of rhythmic gymnastics.By means of video analysis and mathematical statistics,the data on the number,value,movement type,usage,connection mode and completion score of jumping type body difficult movements in the top 8 individual lap exercises in the 2012 London Olympic Games,2014 Rhythmic Gymnastics World Championship and 2018 Rhythmic Gymnastics World Championship are analyzed and studied,and the following conclusions are drawn:1.The international scoring rules of rhythmic gymnastics are constantly updated.The number of difficult movements in the rules is up to 12 in the 2009 edition,6-9 in the 2013 edition and at least one unlimited requirement in the 2017 edition.However,only the best 9 difficult movements are counted as difficulty scores.2.In the scoring rules of rhythmic gymnastics,the difficulty scores of individual jumping difficult movements are adjusted up and down.3.There is a trend of single,unbalanced and high value in the use of difficult jumping movements in rhythmic gymnastics.In connection mode,dance step combination,dynamic action combined with rotation,difficulty of apparatus are oftenused.The connection mode is constantly innovative,which makes the whole set more artistic.4.The variety of technical movements of artistic gymnastics circle gymnastics equipment,combined with high-difficulty and high-value jumping body difficult movements,adds to the danger of the whole set of movements.5.The new rules of rhythmic gymnastics have various forms and types of difficult jumping movements.The number of body difficulty decreases dramatically,and the adjustment of basic and non-basic groups of circle instruments promotes the balanced development of body difficulty movements and equipment difficulty in rhythmic gymnastics.6.The international scoring rules of rhythmic gymnastics require precise specifications for difficult jumping movements,more stringent technical requirements for athletes,improve the status quo of fishing in muddy water by brushing difficulty,and improve the quality of completion.7.Although there is no obvious difference in the use of jumping difficult movements among Chinese athletes,there is still a gap between the quality of the movements and the top level of the world level.It is still a long way to go for Chinese rhythmic gymnastics to enter the first group.
