Abstract

By using the methods such as literature review, expert interview, video analysis and mathematical statistics, this paper analyzes the application of VAR in 240 matches of 30 rounds of China League One in 2019 season. Through the analysis of factors such as the number of reviews, time of review, classification, accuracy rate and the influence on the teams’ results of VAR technology, it is found that the accuracy rate of key decisions is significantly improved, and VAR intervention boundaries are not so clear. The wrong judgment of goals and penalty kicks was corrected in time, and fouls involving red cards could receive effective penalties. VAR technology has no great impact on the flow of the competition. However, for the use of VAR technology in China League One, intervention boundaries are not accurately got hold of, VAR is not operated well, referees are not very meticulous and comprehensive in the VAR viewing process, and communication between VAR and referees is not standardized, which needs to be further improved.
