Comparison Of Performance Structure Of Chinese And Foreign Elite Female Heptathletes From The Perspective Of "Gemini Model"

The all-round event is a comprehensive and independent event combining "speed and strength" and "ability and skill".It has the characteristics of many single events,long time and complex technology.To some extent,the all-round event can comprehensively reflect the development level of a country's track and field sports.This article uses literature data method,mathematical statistics method,comparative analysis method and gray correlation analysis method,combined with the "gemini model" principle to compare and analyze the performance of Chinese and foreign outstanding female heptathlon athletes,examines the athlete's performance structure,and attempts to resolve individual items.The contradiction between "prosperity" and "avoidance of weaknesses" in the development process,clarify the order of individual development,benchmark the Olympic Games to clarify the bottlenecks and opportunities for the development of this project in China,with a view to providing new ideas for related theoretical research and the formulation of athlete training plans;the results show that:(1)After the 10 th National Games,the performance of women's Heptathlon in China has fallen back in a serious shock;there is a serious imbalance among various events,with the most serious decline in javelin,long jump and 200 m performance;the "advantage event" of Chinese athletes is 100 m hurdle,and the "disadvantage event" is javelin..(2)In the 28th-31 st Olympic Games,the overall performance of women's Heptathlon develops slowly;athletes pay more and more attention to speed and explosive force exercises,and speed and jumping events play a leading role,with the fastest development of jumping events;long jump is the "advantage item" of the world's excellent all-around athletes,and 800 m is the "weak item".(3)Compared with the results of women's Heptathlon in the Olympic Games,the results of Chinese and foreign athletes are far behind and fluctuate greatly;the structure of the event group and the single performance structure of Chinese and foreign athletes are the same,the biggest gap is the jumping event group,and the difference between the long jump and the high jump is the most,the development of 100 m hurdles of Chinese athletes is not completely behind the world level.(4)There are some differences between the results of the National Games and the Olympic Games.Although the ranking of the high jump and long jump is similar,the correlation degree is lower than that of the Olympic Games.200 m and javelin are quite different from those of foreign countries in performance structure,which restricts the overall improvement of the performance of Chinese athletes.(5)From the perspective of "Gemini model",the single developmentorder of Chinese Elite Heptathlon Athletes is: 100 M hurdle,200 m,shot put,long jump,javelin,high jump,800 m.The single development order of foreign athletes is: long jump,javelin,100 m hurdle,200 m,high jump,shot put,800m.
