Comparative Analysis And Development Trend Of Complete Set Arrangement Of Chinese And Foreign Elite Parallel Bars Athletes In Tokyo Olympic Period

Parallel bars,as the traditional advantage of Chinese men’s gymnastics,has always maintained the leading position in the world.At present,the international competition is becoming increasingly fierce,and the strength gap between Chinese and foreign excellent parallel bars athletes is gradually narrowing.In order to promote the development of the project and maintain the competitiveness of the project,this paper takes the complete arrangement of Chinese and foreign excellent parallel bars athletes in the 2017-2020 Olympic cycle as the research object,through literature,video observation,comparative analysis,case analysis,expert interview and other methods,through The purpose of the comparative analysis of the new and old rules and watching the videos of the six men’s parallel bars finals at home and abroad in the Tokyo Olympic Games is to understand the characteristics of the complete arrangement of Chinese and foreign excellent parallel bars athletes,speculate on the future development trend of the parallel bars,and provide some theoretical reference for the information collection and action arrangement of Chinese gymnastics team in the parallel bars.The main conclusions are as follows:1.The characteristics and trends of difficulty groups in this cycle: in this cycle,the gap between the overall difficulty of foreign athletes and Chinese athletes has been very small.China’s top parallel bars athletes are still competitive in terms of the difficulty of arranging in sets.In terms of the distribution trend of movement difficulty,the distribution of difficulty of Chinese athletes is basically stable,and the use frequency of ultra-high difficulty group is slightly on the rise;the use frequency of low difficulty group and high difficulty group of foreign athletes is on the rise,and the use frequency of middle difficulty group is on the decline.2.Characteristics and trends of the complete set of movement groups in this cycle:the frequency of action use of each movement group of Chinese athletes remained stable in the Tokyo Olympic cycle,and the ratio of action frequency of four groups was close to 8:5:14:3.The frequency of action use in group I of foreign athletes is on the rise and close to that in group III.The ratio of action quantity in four groups is about11:5:11:3.3.This cycle arranges the popular movements in a complete set: the first group of domestic athletes often use Healy and supporting back swing to split their legs and flip forward for 5 / 4,and foreign athletes often use Healy and supporting front swing to turn 180 ° into handstand and Makuts;the second group of domestic athletes often use hanging arm and back swing to turn forward and flip forward to support and hanging arm and swing back to turn backward for two weeks,while foreign athletes often use hanging arm and back swing to turn forward and flip forward to turn Support: Group III domestic athletes often use the combination of "double back up" and "double flight" movements,while foreign athletes often use the type of back up movements;group IV domestic athletes often use the combination of support front swing and back bend for two weeks and support back swing front group for two weeks under 180 °,foreign athletes often use support back swing front group for two weeks under 180 °.4.Development trend of each movement group: in group I,the horizontal axis rotation movement starting from the support will be gradually reduced,and only the technical action of "5 / 4 forward somersault after the support".The technique of vertical axis rotation with Heli as the core may become the mainstream of this movement group;the use of group II will be further reduced,and the emergence of innovative movements and changes of rules are urgently needed to obtain new development opportunities;group III will be further developed,and foreign athletes may focus on the innovative development of short radius looping movements.Chinese athletes need to get rid of the dependence on the pendulous swing and seek innovation and development as soon as possible.In the fourth group,the foreign athletes have developed mature under the condition of 180 ° back swing and front somersault,and the space for improvement is small.The overall difficulty of domestic athletes is lower than that of foreign athletes,so there is more room for improvement.
