Study On The Variations Of Match Running Distance Among Different Playing Positions In 2018 Chinese Super League

Football is a team sport which players switch back and forth between low-intensity and high-intensity.It requires players to be able to use their skills,team tactics,and physical fitness throughout the season.Better physical fitness is the ultimate in player skills and tactics.This premise is an important basis for winning the game.The most obvious performance is in the player's running ability.Therefore,the research on the player's running ability is the basis for the development of other skills.Although high-intensity running only accounts for a small part of the total running distance,studies have shown that high-intensity running provides a greater chance for the team to win the game at the crucial moment of the game.As the highest level professional football league in China,the Chinese Football Super League has the highest performance standard of the current domestic football competition level and is also the hope of China's football development.Each season of the Chinese Football Super League,each team has 30 rounds of competition,seeing 30 rounds as a continuous process,each round with different external environment,the team's ability is high or low,then whether the team player's distance fluctuation range in 30 rounds is related to the ranking of the team's standings is the research purpose of this study.This study used video analysis,literature data,mathematical statistics,logic analysis and other research methods to study the 16 teams in the 2018 Chinese Super League,and the players in 240 games(only including the game).The player,and does not include the goalkeeper,through the integration of the AMISCO PRO video analysis software to record the data of the running distance of the Super League players,using SPSS 20.0 software to analyse the variation range of the 2018 Super League players in 30 rounds.The relationship between the rankings of the team's standings was analyzed,and the results showed that:1.The correlation between the variation range of the total running distance of the Super League team and the ranking of the team standings was weakly correlated(correlation coefficient rs=0.17),and there was no significant correlation between the total running distance of the team and the ranking of the team standings(P=0.52),with a moderate effect(ES=0.67).2.The correlation between the variation range of thehigh-intensity running distance of the Super League team and the ranking of the team standings was weakly correlated(correlation coefficient rs=0.16),and there was no significant correlation between the total running distance of the team and the ranking of the team standings(P=0.56),with a moderate effect(ES=0.62).3.The correlation between the variation range of the sprint running distance of the Super League team and the ranking of the team standings was weakly correlated(correlation coefficient rs=0.19),and there was no significant correlation between the total running distance of the team and the ranking of the team standings(P=0.49),with a moderate effect(ES=0.72).In conclusion:the smaller the fluctuation of the team's total running,high-intensity running,and sprinting distance,the higher the team's ranking is,the higher the overall level of the team;the team always runs,runs at high intensity,The greater the fluctuation of the sprint running distance,the more generally the team ranks lower,the lower the overall level of the team.
