This study aimed to evaluate the chronic effect of an exercise program in resting blood pressure values ​​of school children aged six to nine years old with overweight and obesity in public schools of the city of OuroPreto, Minas Gerais - Brazil, comparing the systolic and diastolic blood pressure of these students before and after an intervention program. Method: This is a randomized clinical study of intervention, quasi-experimental, double-blind, pragmatic, with the study of the individual unit. Seventy-nine children participated in the interventional study and were considered a convenient sample. These subjects were allocated by randomization into two groups: the intervention group (n = 40) and the control group (n = 39) practised physical activity three times a week for 50 minutes and were followed for 4 months. The exercise intensity was determined by open-circuit spirometry. Blood pressure was measured three times consecutively and the average was used. Results: After the intervention, there was no evidence of significant chronic effects of a regular program of exercises on basal levels of blood pressure of obese children between 6 and 9 years old. Conclusion: In this study, there was no evidence of significant effects from a program of regular physical activity on basal levels of blood pressure of obese children between 6 and 9 years old.
