“…Direct measurement of gas exchanges during incremental cardiopulmonary exercise test remains the gold-standard methods to predict metabolic or cardio-respiratory abnormalities in the patient population. 6,7,30 However, field exercise tests, such as the 6MWT, have been progressively advocated as alternative procedures in the assessment of functional capacity of healthy subjects or patients. Walking is, of course, one of the normal activities of life; it reflects the capacity to undertake daily activities.…”

“…The importance of training and exercise testing in obese children is well documented. 6,7,10,15,30 Assessment of functional capacity assists in the metabolic and cardio-respiratory diagnosis and derives individualized training guidelines for this population over weight-loss and rehabilitation programs. Direct measurement of gas exchanges during incremental cardiopulmonary exercise test remains the gold-standard methods to predict metabolic or cardio-respiratory abnormalities in the patient population.…”

“…However, physical training is recognized as a therapy and has become more and more administrated over the past decade, 6 --9 especially in weight management programs. 6,7,10 The maximal fat oxidation rate (FATmax) power called 'LIPOXmax' represents the exercise intensity at which the highest rate of lipids is oxidized. On the basis of the crossover concept, 11 several studies have individualized and calibrated the intensity of exercise training at LIPOXmax and showed that this type of training is efficient for contracting the metabolic dysfunction-related obesity, consequently leading to better lipid oxidation during exercise, as well as body composition and insulin sensitivity improvement 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.

“…On the contrary, EE associated with real physical activities (kJ·min -1 and kJ·d -1 ) were not significantly different before and after the weight reduction programme in spite of BW loss, indicating an increase in type or intensity of physical activities. In fact, time and EE corresponding to moderate physical activities increased from 21 to 49 min·d -1 (P < 0.03), and from 0.13 to 0.49 MJ·d -1 (P < 0.025), respectively, at the expense of sedentary activities during the weight reduction programme [80].…”

-Energy expenditure (EE) is a major determinant of energy balance and body composition. The objectives of this paper were to review the contributing factors of the main components of daily EE (DEE) and the inter-individual variability in these components in non-obese (NOb), obese (Ob), and post-obese (POb) adolescents. Body composition especially fat-free mass (FFM), is the major determinant of the basal metabolic rate which contributes 50-70% of DEE, whereas fat mass (FM) is a significant factor only in obese subjects. Physical activity is the second main variation factor of DEE, whereas growth, the thermic effect of food, and thermoregulation are generally of marginal importance. The energy costs and EE associated with various sedentary and physical activities were assessed in NOb, Ob and POb subjects both in standardised and in free-living conditions. The interindividual variability of DEE is high, even after adjustment for body composition, mainly because of great differences in time devoted to the various physical activities. DEE and EE associated with sleep and sedentary activities are significantly higher in Ob than in NOb, but not after adjustment for FFM. On the contrary, EE associated with physical activities is not significantly different between Ob and NOb adolescents, but 61% lower in Ob subjects after adjustment for body composition. Multidisciplinary weight-reduction programmes including moderate energy restriction and physical training result in great FM loss, maintenance of FFM, improvement of physical capacities, but reductions in organ and tissue metabolic rate and in EE associated with the various sedentary and physical activities, which may favour body weight regain in the less active POb subjects. body composition / basal metabolic rate / physical activity / thermoregulation
