Descrição: We aimed to examine the interchangeability of techniques used to assess maximal oxygen consumption ( ) and maximal aerobic power (MAP) employed to express the maximal fat oxidation point in obese children and adolescents. Rate of fat oxidation were measured in 24 obese subjects (13.0 ± 2.4 years; Body Mass Index 30.2 ± 6.3 kg m −2 ) who performed a five 4-min stages submaximal incremental cycling exercise. A second cycling exercise was performed to measure . Results are those of the 20 children who achieved the criterion of RER (>1.02) to assess the attainment of . Although correlations between results obtained by different methods were strong, Bland–Altman plots showed little agreement between the maximal fat oxidation point expressed as a percentage of measured and as % estimated according to ACSM guidelines (underestimation : −5.9%) or using the predictive equations of Wasserman (−13.9%). Despite a mean underestimation of 1.4% several values were out of the limits of agreement when comparing measured MAP and Theoretical MAP. Estimations of lead to underestimations of the maximal fat oxidation point.
