Abstract – The aim of this study was to investigate the correlation between physical activity measured by accelerometry and excess weight in schoolchildren. Three hundred and ninety one school-age adolescents (10 to 18 years old) participated in the study. The cut-off points used to estimate time spent in physical activity were: moderate ≥3.0 METs and vigorous ≥6.0 METs. Student’s t-test and Pearson product-moment correlation coefficient were used to verify statistical differences and correlations between physical activity and body mass index (BMI). Statistical significance was set at p
