Association between body mass index and cardiorespiratory fitness as predictor of health status in schoolchildren
Objective: Evaluate the cardiorespiratory fitness (CRF) and the body mass index (BMI) of schoolchildren according to the cutoff points established by the Fitnessgram®. Just as determine the influence of BMI on CRF in children and propose an equation for predicting VO2max from the body composition. Method: The sample consisted of 288 students of basic level of public education in the city of Aracaju - Sergipe - Brazil, aged between 10 and 14 years, of these, 142 were female. To evaluate the CRF the 20-m shuttle run test was chosen. The results of the variable were classified in accordance with the criteria established by the Fitnessgram®. Results: It was evidenced that the cardiorespiratory fitness on males was higher than females. Relative to BMI, there were no differences between the groups, while more than 80% of the entire sample behaved within criteria established by the Fitnessgram®. On the other hand, 57% of the female group presented VO2max below criterion. It was confirmed an inverse relationship between VO2max and BMI on children and adolescents. Conclusion: The students in this study showed adequate levels of body composition and CRF below the area related to health, according to the criteria of the Fitnessgram®. The proposition of a linear regression equation to estimate VO2max without exercise pointed out an inverse relationship between both variables.
