Characteristics of the study participants.

Introduction
More than a third of the world’s population was under full or partial lockdown during COVID-19 by April 2020. Such mitigation measures might have affected participation in various Physical activity (PA) and increased sedentary time. This study aimed to assess the effect of the COVID-19 mitigation measures on participation of adults in various PA types in Rwanda.
Methods
We collected data from conveniently selected participants at their respective PA sites. We assessed the variation in time spent doing in four types of PA (Work related PA, PA in and around home, transportation PA and recreation, sport, and leisure purpose) across different pandemic period. We also evaluated the sedentary time over the weekdays and on the weekends.
Results
A total of 1136 participants completed online assisted questionnaire. 71.4% were male, 83% of the study participants aged 18 to 35 years (mean = 29, (standard deviation = 7.79). Mean time spent doing vigorous PA as part of the work dropped from 84.5 minutes per day before COVID-19 to 58.6 minutes per day during lockdown and went back to 81.5 minutes per day after the lockdown. Time spent sitting on weekdays increased from 163 before COVID-19 to 244.5 minutes during lockdown and to 166.8 minutes after lockdown. Sitting time on weekend increased from 150 before COVID-19 to 235 minutes during lockdown and to 151 minutes after lockdown. Sleeping time on weekdays increased from 7.5 hours per day before COVID-19 to 9.9 hours during lockdown and to 7.5 hours after lockdown while it increased from 8 hours before COVID-19 to 10 hours during lockdown and to 8 hours per day after lockdown during weekends.
Conclusion
The study emphasizes the significance of diverse PA, including home-based programs, during pandemics like COVID-19. It suggests promoting PA types like work-related, transportation, and domestic works during lockdown and similar period.
