Atividade física e saúde na aula de educação física: análise de uma intervenção de base escolar no município de Canguçu/RS

Abstract

The study aimed to evaluate a school - based intervention and its effects on the level of physical activity and knowledge about healthy lifestyle components of schoolchildren in the city of Canguçu / RS. Fifteen schools were selected to participate in the study, which were divided according to the time of exposure to the intervention (group 1- schools that joined the intervention in the year of 2011 and remained in 2012; Group 2 schools that joined the intervention from the year 2012). The intervention strategies were: the training of teachers on the subject, delivery of didactic material (handouts and posters) and a scientific event to exchange experiences among teachers. The level of physical activity (active: ≥ 300 minutes / week) and knowledge about health and components of healthy lifestyle (continuous score through the number of correct answers, ranging from 0-10) were measured by self-administered questionnaire. The study lasted eight months and had the participation of 624 students of both sexes. There was a decrease in the level of physical activity (p <0.001) and an increase in the level of knowledge (p <0.001) in the postintervention, with higher averages in the test grade among schoolchildren with a longer exposure time to Intervention group 1. There was a tendency to increase the level of knowledge according to the increase in the number of lesson plans developed by teachers (p <0.001). It was concluded at the end of the study that a short-term intervention improved the level of knowledge of schoolchildren. Keywords: motor activity; knowledge; Intervention studies
