Research On Winning Factors Of Free-ski Half-pipe

As the official event of the Winter Olympic Games,Free-ski Half-pipe has only developed for 5 years in China,and the overall strength of the domestic team is quite different from foreign countries.Studying its winning factors is of great significance from both theoretical and practical aspects.This paper selects the winning factors of Free-ski Half-pipe project through literature method and expert interview method,then screened,supplemented and finalized through Delphi method and hierarchical analysis,and further analyzes the final winning factors based on video observation method to ensure the scientific nature and rationality of the winning factors,and analyze the connection between the winning factors,so as to provide theoretical reference for improving the winning probability of Chinese athletes in the international field.The results showed:1.The winning factors of freestyle skiing Free-ski Half-pipe project can be divided into internal factors and external factors,with a total of 9 primary indicators and 47 secondary indicators,including 5 primary indicators,31 secondary indicators,external factors 4 primary indicators and 16 secondary indicators.In the winning factor group,internal factors account for 66%,external factors are 34%,and internal factors are 32%greater than external factors,indicating that internal factors occupy the main position in the winning factor system and external factors occupy the secondary position.2.According to the level of weight,order the importance of internal factor level indicators,including skills,tactics,psychology,physical fitness and intelligence,and order the importance of external factors level indicators,including coaches,referees,opponents and field environment.Of the 47 secondary indicators,with 14 winning factors with weighted mean of 4.50,statistics are very important(weighted mean is less than 5.00 or equal to 4.50),including 7 of internal factors and 7 of external factors.3.Combined with the 2018 Pyongyang Free-ski Half-pipe final video analysis that China’s excellent men athletes and the world excellent men athletes turn movement difficulty gap is 360,flip difficulty gap is 180,empty height gap is 2.6m;China excellent women athletes and the world excellent women athletes turn movement difficulty gap is 360,empty height gap is 0.8 meters,but China’s excellent women athletes did not use flip movement in the game.4.The relationship between the winning factors is a close connection,interaction;central unity,highlighting the key points.5.The overall strength is a big gap between the Chinese athletes and the outstanding foreign athletes.In the usual training,we should strengthen the training of improving the height and difficulty in the movement of the air.
