Physical Activity Level Alterations Due to the Lockdowns: A Multi-Center Greek University-Based Study.

Objective: This cross-sectional study determines the impact of the pandemic lockdowns on physical activity, and evaluates the factors associated with physical activity cessation on students and personnel of eight Greek Higher Education Institutions.

Materials and methods: A total of 6,380 volunteer participants completed a survey reporting their physical activity levels and perceptions during the COVID-19 pandemic. The survey was made available through an online platform.

Results: Both the conduct and intensity of physical activity were significantly reduced from the pre-pandemic era to the second lockdown (P<0.001). Walking was the most frequently selected type of physical activity, in all periods except for the second lockdown. Loss of interest (52.4%) was the main, self-reported factor for cessation of physical activity. Females had a 31% lower probability of ceasing physical activity during lockdowns.

Conclusion: The conduct and intensity of physical activity decreased significantly during the pandemic. Female gender, annual checkup attendance, and specific physical activity types during the pre-pandemic era were associated with a reduction in the risk of pausing physical activity during lockdowns. Lockdowns may be implemented in future health crises, hence measures for maintaining the physical activity of the general population, such as online group sessions and support from healthcare professionals, should be prepared.
