Research On The Routine Choreography And Development Trend Of Men's Parallel Bars During The Tokyo Olympic Period

Gymnastics is the traditional advantage of China's competitive sports in project,in the world gymnastics competition has maintained a leading position.Since the 1980s,Li Ning,Li Yuejiu,Li Jing,Huang Liping,Li Xiaopeng,Yang Wei and other world champions and Olympic champions have been born.After entering the 21st century,in addition to Li Xiaopeng won the gold medal in the Beijing Olympic Games parallel bars to continue to lead the world trend,there have been world champions and Olympic champions such as Wang Guanxi,Teng Haibin,Feng Wei,Zhang Chenglong,Lin Chaopan and Zou Jingyuan.It can be said that in the six projects of men's competitive gymnastics,parallel bars have always been the gold medals of Chinese athletes,and it is also the one with the most medals and the best development so far.This paper analyzes the arrangement of athletes' complete sets of movements by studying the set of movements of the parallel bars athletes in the three contests,and draws the future development direction of the parallel bars.In-depth study of the new rules,through the changes in the rules and the trend of action development,provide a theoretical reference for the athletes of various countries to arrange a more reasonable set of actions.This paper uses the literature data method,video observation method,mathematical statistics method and logic analysis method to statistically analyze the types,difficulty and completion of 24 athletes in the finals of the Rio Olympic Games and the 47th and 48th World Gymnastics Championship Parallel Bars.The following conclusions are drawn:1.The action group of the parallel bars is changed from 5 in the previous cycle to 4 in the new cycle.The original ? and ? action groups are combined into one and become the third action group of the new cycle.The V action group of the cycle becomes the ? action group of the new cycle,and this change results in a decrease in the action group.2.The new cycle has a limitation on the specific repetition of D score and the number of actions used,which limits the development of the III action group.The number of actions of the group is significantly reduced,and the number of actions of the first and second groups is significantly increased.The rules have a set of actions for the set of actions.The trend of guiding to the I and II action groups.3.The average D score of the parallel bars movements of the two world championships in the new cycle are 6.45 points and 6.475 points,which is an upward trend.According to their own abilities and characteristics,the athletes create a reasonable set of movements to improve the D score.4.The most hang swing and short-radius loopback movements in the selection action,the number of uses in the two World Gymnastics Championships accounted for 40%of the total number of actions,with the main body of "Tippelt" and the rear upper body;The percentage of support swings used in the two World Gymnastics Championships was 35%and 31.25%,respectively,and has been in a standing position with the ? action group.5.The support swing type is mainly used to support the swing swivel;The upper arm swing gradually became the "transitional" action of the athlete;"Double salto fwd.t.w.1/2t" has become the trend of"regulation",dismount.6.In the new cycle,athletes pay more attention to E score,and the average E score is on the rise.The D score is still the basis for the athletes victory,but the E score gradually becomes the key to the athlete's victory.
