The Movement Program for an Active and Healthy Lifestyle in Adolescents

School is a favorable environment for the development of actions aimed at healthy behavioral changes. This project proposes to evaluate the effectiveness of an intervention program on aspects of lifestyle, with a focus on physical activity (PA) and reducing sedentary behaviors, and the relationship of these factors with the academic performance of students in the school from Florianopolis, SC, Brazil. This is a randomized controlled intervention study enroling classes of 7th to 9th grade of fundamental education. The intervention program will last for one year (about ten months), with three focuses: training of teachers, educational and environmental changes to behavior change.
