Virus (COVID-19) Epidemic and Sports Performance: Evidence from Asian Professional Football Clubs

ABSTRACT

When the COVID-19 epidemic spread around the world, researchers did many studies about sports and COVID-19, but there was not much quantitative research. Therefore the purpose of this study was the effect of the COVID-19 epidemic on the sports performance of Asian football clubs with quintile regression. This study used panel data for fifteen Asian football clubs from April to December 2020. The research used the points of Asia football clubs to estimate their sports performance. Also, this study collected cases and deaths caused by the COVID-19 epidemic as the other two variables. According to the results, because coefficient estimates (degree of depend-ence) for each quantile are equal (for both effects CA on SP and effect DE on SP), the dependence structure is said to be constant. Therefore, a positive estimate and equivalent in all quantile for the impact of cases of COVID-19 virus (CA) on Sports Performance (SP) show that cases of COVID-19 virus (CA) have a constant positive effect on sports performance (SP). A negative estimate and equivalent in all quantile for the impact of death of COVID-19 virus (DE) on Sports Performance (SP) show that death of COVID-19 virus (DE) has a constant negative effect on Sports Performance (SP). © 2023, Stanislaw Podobinski Publishing House of the Jan Dlugosz University.
