Educational Program and Schoolchildren's Energy Expenditure

Intervention was applied to classroom teachers by the multidisciplinary team of the RRIDA Project. Training lasted six weeks, 12 hours devoted to physical activity and 18 hours to nutritional content. Modules of educational activities to classroom teachers were to be replicated at PE classes to children from 1st and 2nd grades of three exposed schools. The physical activity module was based on a theoretical approach of physical activity benefits and risks for health, children's physical fitness and activity patterns, physical education and change behavior models.
