- Brief Summary
Physical activity is a factor that contributes to a motor and cognitive development in early childhood. Currently, childhood obesity has grown steadily in Chile. This study aims to evaluate the impact of a school environmental intervention on the physical activity and cognitive functions in 1st-grade schoolchildren during the COVID-19 pandemic. The study will use a randomized experimental design with a sample of 300 schoolchildren divided into a control and an intervention group (n=150 each group). Sociodemographic characteristics and lifestyle of the schoolchildren will be obtained through a questionnaire answered by parents/guardians. Cognitive function will be evaluated using the TENI test by tablet and physical activity will be measured during 7 consecutive days using accelerometers (Actigraph GT3X and wGT3X-BT). Both groups will receive a lecture aimed at schoolchildren. Teachers of the intervention group will also receive a talk regarding the intervention that will take place in their school environment, which includes a circuit of psychomotor games painted on the recess playground floor. ANCOVA analysis will be performed, adjusted for age and sex; then, a multivariate linear regression model will be applied considering the significant variables and adjustment. The significance level will be p\<.05. SPSSv25 and R version 3.14 will be used for the analyses. The intervention is expected to contribute to the increase of physical activity favoring the school environment within a context of vulnerability and with a low-cost initiative

Group Intervention Description Intervention Physical activity The implementation of painted games will consist of adapting a space destined for recreation, designing a psychomotor circuit that does not require contact between peers, or manipulation of objects to maintain COVID-19 sanitary and safety protocols. The schools in the intervention group will receive the online educational talk aimed at schoolchildren and a talk aimed at Physical Education teachers.
- Primary Outcome Measures
Name Time Method Physical activity change baseline up to 5 months Accelerometry data will be valid if they present ≥ 3 days of measurement with a minimum of 9 hours of use per day.
Cognitive function change baseline up to 5 months The battery is composed of 8 games to assess the functioning of attention, visuospatial and visuomotor development, memory system, language, and executive functions in children aged 3 to 9 years. Test, TENI.
- Secondary Outcome Measures
Name Time Method Flowmetry change baseline up to 5 months Flowmetry will be analyzed using the mean of three measurements recorded with the pediatric Mini wright (400l/m).
Hand grip strength change baseline up to 5 months Manual grip strength will be assessed three times on the dominant arm using a digital dynamometer (TKK504) fitted to the palm of the schoolchild's hand
