| In the complex and diversified information environment of competitive sports,the application of big data thinking is helpful to solve the problems in the development of competitive sports.As a winter outdoor sport,the freestyle skiing aerials project has high-risk and difficult movements,and athletes' performance on the field is susceptible to environmental and other factors.In the fifteen years of aerial skill World Cup competitions,China has achieved remarkable results,but in the 2010,2014 and 2018 Winter Olympics,China's aerials female athletes missed the gold medal.It is obviously impossible to based on the data of several games to scientifically and accurately measure the athletes' athletic performance.In this study,the top three female athletes and the competition environments were selected as the research objects,and their competition data and performance in the competition were taken as the observation objects.From the perspective of big data,this research collects as much data as possible,quantify the results of the competition,and pay attention to the relevant relationships.Through the literature material method,questionnaire survey method,mathematical analysis,comparative analysis and video analysis,analysis of the competitive performance of excellent female athletes in the competing situation,comparative analysis and analysis of influencing factors about athletic performance,the conclusion has the following four points:(1)The overall difficulty of the selection of excellent female athletes in aerial skills is relatively concentrated and moderate.There are fewer athletes who compete with a high degree of difficulty;the landing performance of the excellent female athletes in aerial skills is greater than that of the air form.(2)The U.S.aerials female athletes have the highest difficulty coefficient in the competition.China's athletes have a high rate of action success but relatively insufficient reserve of action difficulty.China's gold medalists' overall performance is better,but foreign gold medalists are better at challenging difficult movements.(3)There is a significant difference between the aerial performance of excellent female athletes in the Olympic performance and the World Cup.(4)After factor analysis of the influencing factors of outstanding female athletes' athletic performance,five common factors can be drawn: the competition environment,competition action,competition status,competition cognition,and competition opponent's cognition.There is a significant correlation with the athlete's competition performance.The competition venue,weather,temperature,snow temperature,participationexperience,age and other factors will affect the competition performance of some players.Therefore,this study suggests that Chinese athletes should take advantage of high quality and high stability;improve the reserve team of China's excellent female athletes.In the Winter Olympic Games,we should ensure the quality of action completion and win in stability.Use more comprehensive information to measure the impact of different factors on athletes' competitive performance in the era of the big date. |
