BMI was measuredas an indicator of obesity and the risk was classified according to international benchmarks.Cardiorespiratory fitness, measured using the 6-min walk test (6’WT), oxygen consumption byVO(2)max, the distance and the number of steps, were grouped and compared with the bodymass index reference values.Results: In subjects with BMI ≥ 25 kg·m-1, negative correlations were observed in the distanceby 6’WT (rho = -0.50), number of steps (rho = -0.45), VO(2)max (rho = -0.49), and LVEF (rho= -0.32).Conclusion: This study suggests that higher body mass index values, "obesity paradox", arenot associated with a higher cardiorespiratory level using VO(2)max.
