The COVID-19 pandemic has entailed a significant socio-economic impact on various layers of the population. In many countries, attempts to control viral dissemination involved lockdown measures that limited citizens' overall mobility and professional and leisure activities.

This systematic review investigates the impact of COVID-19-induced lockdowns on university student physical activity and sedentary behav-ior, as these relate to physical and mental well-being.

Data was collected through PubMed/MEDLINE, Embase, SCOPUS, and APA PsycInfo databases until January 2021.

Seven studies conducted in five different countries (United States, Spain, Italy, China, and United Kingdom) were included in the final review. Overall, most studies reported a significant decrease in mild physical activity (i.e., walking) among undergraduate students but not among graduate students. Consistently, most studies reported a significant increase in sedentary time (i.e., sitting time on weekdays) in undergraduate students but not in graduate students. We observed that students who were more sedentary previous to lockdown, increased or did not change their moderate and/or vigorous physical activity. In contrast, those who were less sedentary previous to lockdown decreased their moderate and/or vigorous physical activity.

COVID 19 induced lockdowns appear to have negatively affected walking and sedentary behavior among undergraduate students but not among graduate students. Our results highlight the importance of promoting the World Health Organization recommendations for physical activity and sedentary behavior among university students to improve health outcomes.
