Abstract: The purpose of this paper is to master the cognition, coping and exercise behavior of college students on COVID-19, so as to provide reference for universities and relevant departments to formulate targeted COVID-19 prevention and control propaganda, intervention strategies and measures. Through questionnaire survey and data analysis, it is found that college students pay more attention to COVID-19 and have a comprehensive understanding of its disease characteristics, preventive measures and risks, and tend to choose positive coping styles. Although there are certain negative emotions, they can be adjusted by taking part in physical exercise. During the period of epidemic prevention and control, college students忆 awareness of physical exercise importance has increased significantly, and their explicit behavior of exercise has changed little. There is a positive correlation between college students' cognitive level of epidemic situation and their coping style and exercise behavior. With the normalization of epidemic prevention and control work, college students need to internalize their correct cognition into the motivation for them to respond more actively and stably, and effectively improve their physical and mental qualities by effective physical exercise, so as to contribute to the accurate prevention and control work of colleges and universities and contribute to the complete victory of the national epidemic prevention and control work.

Key words: COVID-19, cognitive level, coping style, exercise behavior
