| Purpose:This paper analyzes the winning indicators and their differences of teams at different levels in the 2020 and 2021 seasons,and discusses the rules of winning indicators in the competitions of teams at different levels,aiming at solving the problem of how to better use physical strength and technology to improve the sports performance of teams at different levels,so as to effectively improve the sports performance of teams.Methods:In this study,literature analysis,software(video)analysis and mathematical statistics were used to analyze and study the winning indexes of 2020and 2021 seasons of Chinese Super League.The data came from the official cooperative Amisco system,among which 160 games were played in 2020 season and180 games were played in 2021 season.A total of 680 sets of technical and run-related game data.The physical,technical and tactical indexes of Chinese Super League players recorded by Amisco system can be divided into four variables,25items in total:Goal shot variable(shot,shot on target rate)、Attacking variables(the number of passes and their success rate,the number of forward passes and their success rate,the number of crosses and their success rate,corner kicks,offsides,the number of possession times in the attacking zone)、Defensive variables(foul,yellow card,red card,the number of scrambling and its success rate)、Running variables(total distance moved,average running speed,average running speed in possession of the ball,average running speed in possession of the other team,sprint times,sprint distance,high speed running times,high speed running distance,medium speed running distance).Results:(1)When the top eight teams play the top eight teams,the percentage of shots on target(p<0.01,η~2=0.134),success rate of crosses(p<0.05,η~2=0.077),corner kicks(B=0.616,p<0.01),number of possession times in the attacking zone(B=0.053,p<0.01),success rate of scramble(B=0.117,p<0.05),average running speed in possession of the ball(B=-3.445,p<0.05),average running speed in possession of the opponent(B=2.704,p<0.05),number of sprint(B=2.313,p<0.05)had significant influence on the match;In 2021 season,shooting rate(p<0.01,η~2=0.139),number of crosses(B=-0.145,p<0.05),success rate of crosses(p<0.05,η~2=0.085),success rate of scramble(p<0.05,η~2=0.092)had a significant impact on the game.(2)When the current eight teams face the last eight teams,they will shoot in 2020(p<0.01,η~2=0.184),number of passes(p<0.01,η~2=0.185),pass success rate(B=-2.572,p<0.01),forward pass times(p<0.01,η~2=0.196),forward pass success rate(B=1.820,p<0.01),and middle pass success rate(p<0.01,η~2=0.200),the number of times to control the ball in the third attack zone(B=-0.073,p<0.05),and the yellow card(p=0.013,η~2<0.05).The success rate of fighting(p<0.001,η~2=0.250),total moving distance(B=-0.011,p<0.05),number of sprints(B=4.127,p<0.05),and number of high-speed runs(B=-1.926,p<0.05)have a significant impact on the race;In 2021season,shooting(B=0.102,p<0.01)and shooting rate(p<0.05,η~2=0.119),number of passes(p<0.01,η~2=0.173),pass success rate(p<0.01,η~2=0.129),forward pass times(p<0.01,η~2=0.155),forward pass success rate(p<0.01,η~2=0.124),the number of hits(B=0.072,p<0.01),the success rate of hits(p<0.01,η~2=0.139),corner kick(B=0.756,p<0.01),average running speed(B=-17.614,p<0.01),high-speed running distance(B=-0.102,p<0.05),and medium-speed running distance(B=0.026,p<0.01)have a significant impact on the competition.(3)When the bottom eight teams played the top eight teams,the percentage of shots on target(p<0.001,η~2=0.301),the number of crosses(B=-0.216,p<0.05),corner kicks(B=0.543,p<0.05),offsides(p<0.05,η~2=0.091),average running speed in ball control(B=-4.534,p<0.05)had significant effects on the game;2021 season shooting(p<0.05,η~2=0.126),shooting percentage(p<0.01,η~2=0.161),passing times(p<0.001,η~2=0.239),passing success(p<0.01,η~2=0.160),forward passing times(p<0.001,η~2=0.232),forward passing success rate(p<0.01,η~2=0.174),offside(p<0.01,η~2=0.146),attack three zones possession times(p<0.01,η~2=0.158),the average running speed when the other side control the ball(p<0.05,η~2=0.102)has a significant effect on the race.(4)When the bottom 8 teams played the bottom 8 teams,the 2020 season shot(p<0.05,η~2=0.092),shot rate(p<0.01,η~2=0.117),passing success rate(B=0.567,p<0.05),cross success rate,((B=-0.077,p<0.01))yellow card(B=0.807,p<0.01),red card(B=-2.791,p<0.01),scramble times(B=0.080,p<0.05),total distance moved(B=0.002,p<0.05),average running speed(p<0.05,η~2=0.067),average running speed when the opponent controls the ball(B=2.195,p<0.05),sprint times(p<0.001,η~2=0.221),sprint distance(p<0.001,η~2=0.194),high speed running times(p<0.05,η~2=0.690),medium speed running distance(B=-0.012,p<0.05)had significant influence on the race;2021 season shooting(p<0.01,η~2=0.116),on-target percentage(p<0.001,η~2=0.136),corner kick(p<0.01,η~2=0.082),offside(p<0.01,η~2=0.084),average running speed in possession(B=-1.598,p<0.05)had a significant effect on the competition.Conclusions:(1)Regardless of the level of the two teams,the variable of goals and shots is the winning index of the 2020 and 2021 seasons of the Chinese Super League,and the shooting rate is an important guarantee for the victory of the game.(2)According to the research results,the top 8 teams in the Chinese Super League win games mainly by attacking means such as high-quality passing,more stable ball control in the penalty area and corner kick.The bottom eight are more likely to use crosses,corners and offsides to win.If they play against strong teams,they need to be more consistent in the box and better at tackling.(3)At present,most of the teams in the competition play the pass and control style,players need to run constantly to get the best position,also need to get the ball through a lot of fighting,for the players need good physical reserves.In the 2020 and2021 seasons of the Chinese Super League,the teams’high-intensity running ability and the average running speed of the two teams in possession of the ball were game-winning indicators. |
