Background To prevent the spread of COVID-19 in the first half of 2020, online classes were held at many universities. The purpose of this study was to investigate the details of physical activity of university students under the declaration of a state of emergency, and to clarify the relationship between changes in the physical activity level and psychosocial factors. Methods The subjects of 200 university students (70 males, 18.4 ± 0.7 years old, 130 females, 18.7 ± 2.9 years old) from 10 universities conducted a physical activity survey (Lifestyle24) online. Results The mean METs before the outbreak of the COVID-19 and under the state of emergency were 1.42 ± 0.27METs and 1.32 ± 0.19METs (p < .01), respectively, with a significant difference of 23.8%. For physical activity (METs · h) of 3 METs or more, there was a significant difference of 39.8% (p < .01), respectively. In the analysis for each behavior, the average sleep time increased by 19.9 minutes (p < .01) and the average traffic activity time decreased by 56.3 minutes (p < .01) during the period of self-restraint from going out. There was no significant difference in the time spent studying and playing sports. The frequency of ball games decreased, and many of the sports could be practiced at home by individuals. Psychosocial factors showed a significant association (p < .01) between the number of new friends and the level of sleep quality and physical activity of 4 METs or more. Discussion Using a web-based physical activity survey system for university students, we were able to show the details of the decrease in physical activity due to the COVID-19 outbreak. Infection prevention and physical activity are not considered to be contradictory, but it is required to promote physical activity while preventing infection in order to maintain physical and mental health.
