Research On The Performance Characteristics Of High Intensity Running In 2020 And 2019 Season Of Chinese Super League Teams At Different Levels

Under the influence of the COVID-19,the Chinese Super League(CSL)will be played on a game-meeting system for the first time in its history,instead of home and away.Game-meeting system often exist in the form of cup,with fixtures,great strength,dense place fixed and slug it turn-based,another league held must meet the conditions of the epidemic prevention and control,training and competition will take place in a closed condition,this will have an enormous effect on the athletes’physical and psychological,which affects the players in the game running performance.Therefore,understanding different levels in the super league team performance in the game to run under different format characteristics,to explore the league top and back side under different system running performance gap between,and the team home and away in the league and game-meeting system running performance difference,and according to the movement characteristics of different format for the team to choice competition strategies and training plans to offer suggestions,so as to improve the team performance in game-meeting system running,this regarding the Chinese super league team improve their scores on the game-meeting system has important theoretical and practical significance.For this reason,this paper takes the top four and bottom four teams of Chinese Super League in 2019 and 2020 seasons as the research objects,plays back the video of 40 matches participated by the team,selects 10 running performance indicators,such as high-speed running distance and times,sprint running distance and times,total running distance,sprint running distance and high intensity running distance when the team is in possession of the ball,total running distance,sprint running distance and high intensity running distance when the opponent is in possession of the ball in each match,inputs the data with Excel2016,and uses SPSS26.0 statistical analysis.The comparative analysis included longitudinal comparison between teams at the top of the league and those at the bottom of the league during the season,as well as horizontal comparison between the seasons,and the following conclusions were drawn:1.In terms of the total distance running index,no matter the top four teams in the league ranking or the bottom four teams,their average total distance running per game will decrease significantly in the competition system.2.In terms of high-speed running performance,the average speed running distance and times of the top four teams in the league ranking are significantly higher than those of the bottom four teams in the game regardless of the match system or the home and away system;In addition,the top four teams in the league table averaged significantly fewer runs per game in the tournament format than in the home and away format.3.In terms of sprint performance,the average sprint distance and times of the top four teams in the league ranking are significantly higher than those of the bottom four teams in the game,no matter the CSL adopts the match system or the home and away system.In addition,teams in the bottom four of the league table ran significantly more sprints per game in the tournament format than in the home and away format.4.In terms of running performance under their own possession of the ball,regardless of the matchmaking system or home and away system,the average running distance,sprint distance and high-intensity running distance per game of the top four teams in the league ranking were significantly higher than those of the bottom four teams in the game under their own possession.In addition,the top four teams in the league had significantly fewer sprints and high-intensity runs per game when in possession of the ball than when in home and away games.The bottom four teams showed a significant increase in sprint distance per game when they were in possession of the ball.5.In terms of the running performance of the opponent in possession of the ball,the average running distance per game of the top four teams in the league ranking is significantly less than that of the bottom four teams in possession of the ball,no matter the matchmaking system or home and away system is adopted in the CSL;In addition,the top four teams in the league saw a significant decrease in the total distance covered per game when the opposing team possessed the ball,compared to the home-away system.
