“…The boys walked 564.9 ± 53.7 m, whereas the girls walked 506.7 ± 55.0 m. Similar walking performance has been reported in previous studies in children. 15,19 The difference between boys and girls could be due to metabolic abnormalities and anthropometric factors, which are usually independently associated with the distance walked. 31 In the present study, we present regression models that allow the evaluator to estimate FATmax for obese children of both genders.…”

Six-minute walking test predicts maximal fat oxidation in obese children

BACKGROUND: Obesity is associated with reduced exercise maximal fat oxidation rate (FATmax), which is generally assessed by cardiopulmonary cycling test. The six-minute walking test (6MWT) presents an alternative method in patients. OBJECTIVE: The aim of this study was to establish a practical reference equation facilitating the prediction of FATmax from the 6MWT in obese children of both genders. DESIGN: This study is a cross-sectional study using mixed linear and multiple regression models. RESEARCH METHODS AND PROCEDURES: Anthropometric measurements were recorded and submaximal cycling test and 6MWT conducted for 131 school-aged obese children, 68 boys and 63 girls. A multiple regression analysis for FATmax, including six-minute walking distance (6MWD), anthropometric and cardiac parameters as the dependent variables, was performed for the two genders separately. RESULTS: Mean 6MWD and FATmax were 564.9 ± 53.7 m and 126.5 ± 12.1 mg min À1 for boys and 506.7 ± 55.0 m and 120.7 ± 10.0 mg min À1 for girls, respectively. The 6MWD, body mass index, Z-score, fat-free mass, waist and hip circumferences (WC and HC), rest heart rate, and systolic and diastolic blood pressures were highly correlated with FATmax for both genders. There was a significant correlation between 6MWD and FATmax in both boys and girls (r ¼ 0.88 and r ¼ 0.81, Po0.001, respectively). Stepwise regression analyses revealed that the combinations of 6MWD with HC for boys and 6MWD with WC for girls improved the predictability of the model (R 2 ¼ 0.81 for boys and R 2 ¼ 0.72 for girls; Po0.001). CONCLUSION: In obese children, the 6MWT can be used to predict FATmax when formal test of exercise capacity and gas exchange analysis are unavailable or impractical. It is therefore possible to prescript targeted exercises at FATmax, without performing indirect calorimetry, just from a field test.

“…In adult cardiac patients after myocardial infarction (MI), it has been shown that the confidence of the patient and their spouse can be significantly improved when a CPET is performed three weeks after the MI. 9 Lastly, CPET (as well as field tests, such as the 6-minute walk test 10 ) can be used to show improvement of physical rehabilitation in children with CHD. Furthermore, a fitness assessment including CPET can be helpful in motivating children with CHD to maintain a healthy body weight or to combat overweight/ obesity.…”

Cardiopulmonary exercise testing in congenital heart disease: (contra)indications and interpretation Cardiopulmonary exercise testing (CPET) in paediatric cardiology differs in many aspects from the tests performed in adult cardiology. Children's cardiovascular responses during exercise testing present different characteristics, particularly oxygen uptake, heart rate and blood pressure response, which are essential in interpreting haemodynamic data. Diseases that are associated with myocardial ischaemia are rare in children. The main indications for CPET in children are evaluation of exercise capacity and the identification of exercise-induced arrhythmias. In this article we will review the main indications for CPET in children with congenital heart disease, the contraindications for exercise testing and the indications for terminating an exercise test. Moreover, we will address the interpretation of gas exchange data from CPET in children with congenital heart disease. (Neth Heart J 2009;17:385-92.)

“…En población adulta existen múltiples estudios publicados que han permitido establecer valores normales [11][12][13][14] . En pediatría ha sido utilizado en niños sanos [4][5][6]9,10,15 , en pacientes con fibrosis quística 7,8 , bronquiolitis obliterante 16 , cardiopatías y trasplantes cardiacos y/o pulmonares, así como también, en intervenciones terapéuticas 17 . Sin embargo, aún sigue siendo poco utilizado en población pediátrica y la falta de valores de referencia ha dificultado su interpretación.…”
