| The Olympic Games are the largest comprehensive Games in the world hosted by the International Olympic Committee.They can be divided into ten different types of sports events,such as the Summer Olympic Games and the Winter Olympic Games.The first Winter Olympic Games were held in Charmony,France,in 1924.Men's speed skating events were listed as formal competitions and many ice events are constantly produced and developed on the basis of speed skating.China participated in the Winter Olympic Games for the first time in 1980.It was not until the 2008 Pingchang Winter Olympic Games that China achieved a breakthrough of zero men's speed skating medal.Gao Tingyu won a bronze medal in the men,s 500-meter race.However,other athletes ranked basically in the middle and lower reaches of the competition.Their achievements lingered for a long time,which has affected the confidence of coaches and athletes.In addition,the 2022 Winter Olympic Games will be held in Beijing.By comparing and analyzing the results of Chinese speed skaters and the top eight speed skaters in the 2008 Winter Olympic Games,the researchers hope to find out the intensity of the competition,the difficulty coefficient of improving the performance of the competition,and to use the linear regression method to divide the group competition and the dynamic competition.Cheng shows it in a holistic and static way,and intuitively sees the specific differences between the performance of Chinese athletes and the top eight athletes,provides specific theoretical data reference for the improvement of the performance of project managers,coaches and athletes,and provides specific theoretical data reference for coaches and athletes preparing for the Beijing Winter Olympic Games in 2022,so as to enhance their enthusiasm and self-confidence in preparing for the Games and strive for it.Achieve better results.In this paper,the development of speed skating at home and abroad is consulted by using the method of documentation.Video observation is used to review the actual situation of the competition for many times.The competition data are analyzed scientifically and meticulously by using the method of mathematical statistics.Firstly,the medal table and the participation of Chinese athletes are summarized and analyzed.Secondly,the time points in the competition are compared and analyzed.Finally,the box chart and the box chart are drawn.The unitary linear regression equation,residual and other mathematical statistical tools are introduced into the performance analysis,and the group competition and dynamic competition are presented by the unitary linear regression equation in a holistic and static way.The specific differences between Chinese athletes and the top eight athletes can be seen intuitively and intuitively,which can provide specific data reference for project managers and coaches,It is concluded that the Netherlands has absolute leading edge on the medal list.China is in the middle and lower reaches.The shorter the distance between events,the smaller the intensity index of competition,the more intense the competition is.The intensity of men s competition is higher than that of women's.The men's 500-meter competition is the most intense.Besides Gao Tingyu,Chinese athletes rank basically in the middle and lower reaches of the medal table,with a big difference in ranking and competitiveness.Strength is not strong,competition projects have certain limitations,relatively concentrated in short and medium distance projects,long distance and collective projects did not qualify for the competition,the speed drop in the back range is large,and the ability of back skating is weak.Through the research,it is found that we should reasonably develop reserve talent echelon construction,pay attention to scientific training,strengthen communication and communication with the world's powerful countries,take short-distance projects as a breakthrough,improve backhaul skiing ability and enhance competitive strength. |
