Objectives To understand the role of household variables on the percentage of physical activity (%PA) during the COVID-19 confinement in Portugal. Study Design A Cross-sectional study design using an anonymous online survey was launched to assess how Portuguese families with children under 13 years of age adjusted their daily routines to the confinement. Methods Separate ANOVAs were performed to investigate how factors, such as the number of children, age, sex, the housing characteristics, and the adults’ job situation, can affect the percentage of time for physical activity (%PA). Results Findings, based on data from 2159 children, indicate that: I) Boys and girls did not differ in the %PA on any of the age groups; II) Children with an outdoor space and who had other children in the household were significantly more active (p<.001); III) Children from families with all adults working from home showed lower levels of %PA; IV) Being younger, having a big outdoor space, having other children in the household, and having at least one adult free from working from home, were significant positive predictors of children’s %PA, explaining 21% of the overall variance. Conclusion Time allocated for PA during this period is reduced compared to what is usually reported on normal days. It is necessary to find strategies to increase children's PA, especially in families where both parents are working and have no outdoor space.

During long periods without school, children are more susceptible to unhealthy behaviors, such as an increase in sedentary behaviors, which has a negative impact on children’s motor competence (MC). The COVID-19 lockdown offered us a unique opportunity to test, in a quasi-experimental setting, the impact of lockdown movement restrictions on children’s MC. We assessed the motor competence of 114 children aged 6–9 years using the motor competence assessment. All children were tested before and after the COVID-19 lockdown. Chi-square and 2 × 2 ANOVA (sex by moment) were used to further analyze the data. Regardless of sex, motor performances in all tests (except for jumping sideways in boys) were lower when compared with performances before lockdown. There was a marked decreasing trend in children’s levels of MC, shifting from an upper to a lower quartile in different tests. The results after the lockdown were always significantly inferior to the results before lockdown in all motor tests (except jumping sideways), in the three components of MC, and in global MC. Children’s global MC score decreased by an average of 13 points in boys and 16 points in girls. The imposed movement restrictions had a negative effect on children’s motor competence development.

Objective: To identify how Brazilian families with children aged under 13 years face the period of social isolation resulting from the COVID-19 pandemic, especially regarding the time spent on physical activity (PA), intellectual activity, games, outdoor activities and screen. Methods: An anonymous online survey was launched on March 24, 2020 in Brazil to assess how families with children aged up to 12 years are adjusting their daily routines to this situation. In the survey, each family reported the daily time each child spent in sedentary activity (sum of intellectual activities, play time on screen, playing without PA) and PA (sum of playing with PA and PA). Results: The main findings based on data from 816 children indicate that most parents consider there was a reduction in the time that children spend practicing PA; increase in screen play time and family activities, differences between sex were found regarding screen play time (boys>girls) and in playing without PA (girls>boys), and there was an age effect for all categories analyzed, with a tendency to increase the total time of sedentary lifestyle and complementary reducing the time of PA over age. Conclusions: The household routines of families during the period of social isolation resulting from the COVID-19 pandemic confirm the general reduction tendency in PA time during childhood.
