The study aimed at evaluating the relationship among anthropometric measurements, levels of physical activity and physical fitness in schoolchildren. A cross-sectional study was carried out in public schools, with 173 adolescents from 10 to 17 years of age. Socioeconomic data were obtained by a structured questionnaire. Anthropometric measures were assessed and classified according to Body Mass Index (BMI)/age and Waist Circumference (WC). The long version of the International Physical Activity Questionnaire (IPAQ) was used to assess the level of physical activity, while the physical fitness level was assessed using the Projeto Esporte Brasil (PROESP) test protocol. 72,3% of the adolescents were eutrophic and 24.3% were overweight and 22.6% were at high risk for cardiovascular disease, with no statistical difference between the sexes (p > 0.05). 53.8% were physically inactive, regardless of sex and nutritional status. 86.1% of the adolescents showed low physical fitness, more significantly for sit-and-reach andsquare tests of females. BMI was directly correlated with physical fitness in the assessment ofupper limb power and agility (medicine ball throw and square test) and indirectly with aerobic capacity and lower limb power (abdominal resistance, horizontal jump and general resistance). The opposite was observed in the correlation of endurance (abdominal and general) and medicine ball throw with WC. Also, there was a likely visceral obesity and consequent cardiovascular risk in females more than in males. These findings reinforce the connection between physical activity and the presence of overweight and obesity in adolescents and also the need to effectively intervene in this groupin order to ensure the prevention of chronic non-communicable diseases in adulthood.
