Introduction: The management of university campuses in the context of COVID-19 makes the mental health of college students draw much attention. Objective: To explore the effects of physical exercise under COVID-19 on sleep quality and mood of college students. Methods: 1983 college students from The Civil Aviation University of China were selected, and their physical exercise state, sleep quality, and emotional state were measured by a questionnaire. Results: Physical exercise has a significant positive effect on college students’ mood and sleep quality, and sleep quality has a considerable impact on their mood. There is no gender difference in mood and sleep quality. The amount of physical exercise has a significant difference in sleep quality and mood. Compared with the students who do a lot of physical exercises, those who do a lot of physical exercises have higher sleep quality and more vital stronger emotional control ability. Conclusion: This study can provide a reference for universities to carry out mental health education during the particular period of epidemic prevention and control.

Introduction: Exercise commitment plays an explanatory and guiding role in an individual's adherence to exercise behavior. However, exercise commitment in recreational situations is poorly studied. Objective: Develop a sporting and recreational behavior questionnaire based on the commitment scale for Chinese urban residents. Methods: Two stages were conducted, the first with a sample of 453 individuals to explore and verify the determinants of behavioral commitment in recreational sport and the fit of the framework, and the second with a sample of 786 individuals to investigate the relationship between behavioral commitment in recreational sport and its determinants. Results: Behavioral commitment in-play sport included five determinants: ‘motivation to participate’, ‘personal involvement’, ‘choice to participate’, ‘opportunity to participate’, ‘social support’. The constructed model showed a good fit. The factors: ‘motivation to participate’, ‘personal engagement’ and ‘interest to participate’, showed a significant positive association with engagement and a significant negative association with a choice to participate. Conclusion: The resulting model shows characteristics of recreational sport behavior and can be used as a measure of commitment to recreational sport behavior among residents of a Chinese city. Level of evidence II; Diagnostic Studies- Investigating a Diagnostic Test.
