“…When the aspect of carrying excessive body mass during exercise is eliminated by using a cycle ergometer in the test, absolute oxygen uptake values can differ for exercise on a treadmill and a cycle ergometer. For exercise on a treadmill, absolute VO 2 values for obese children are higher than for normal weight children [12,17] -similar results were noted in this study. In the exercises on a cycle ergometer, though, absolute oxygen uptake values in obese and normal weight children are usually at the same level [12].…”

“…The relative to body mass VO 2 values are seen to be to be significantly lower in obese children in exercises done both on a treadmill and a cycle ergometer [12,17]. Scaling VO 2 to fat-free mass may or may not eliminate the significant differences between obese and non-obese children [17]. Our study confirmed that significantly higher absolute and relative to fat-free mass and significantly lower relative to body mass oxygen uptake during treadmill exercise is noted in overweight boys compared to normal weight boys.…”

SummaryStudy aim: running economy (RE) is important indicator of endurance performance. During puberty dynamic changes in body composition and function are observed, as such RE is also expected to change. The aim of the study was to compare the running economy (RE) in overweight and normoweight boys during a running exercise performed with constant velocity, and the assessment of changes in RE during puberty. Material and methods: the RE of the subjects was evaluated twice: at the age of 11-12 and two years later. 18 overweight and 17 normal weight boys performed a graded test and a week later a submaximal run on a mechanical treadmill. During the exercise, physiological variables (oxygen uptake, heart rate, pulmonary ventilation, tidal volume and breathing frequency) were measured. Results: the intensity of work in both tests (%VO 2 max, %HRmax) was significantly higher in the overweight boys and decreased with age (non significantly) in both groups. The physiological response during the run in the overweight boys was significantly higher compared to normal weight. When the oxygen uptake was expressed as VO 2 . BM -0.75 , the RE was similar in normal weight and overweight boys. During puberty, the inter-group differences in the metabolic cost of work stay at a relatively stable level. Conclusions: the lowered endurance performance in the overweight boys during puberty remains unchanged. The changes in physiological variables during puberty in both groups occurred in a similar way -the body composition did not influence the course of these changes in puberty.

“…20,24 This procedure, however, underestimates the fitness of overweight and obese subjects. 25 Moreover, VO 2peak /kg body mass also underestimates the VO 2peak of taller subjects. 26 Therefore, several other fractional-power relationships have been suggested such as per kg 0.66, kg 0.75 or kg 0.87.…”

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.)

“…1 This depicts the spectrum of insulin sensitivity/resistance and the role that fitness and visceral body fat play upon insulin and health and time allotted to physical education classes has decreased [57,58]. For children, supplementary exercise and healthy nutritional changes can be successfully promoted in varying environments [59][60][61][62][63]. The most successful programs incorporate consistent dietary guidelines, reduced television viewing time, and increased physical activity into children's daily routine, including the school environment [64] (e.g.…”

The influence of fitness on insulin resistance in obese children

An increasingly pervasive environment of reduced activity and easy access to high caloric food is leading to an epidemic of poor cardiovascular fitness, obesity, insulin resistance and type 2 diabetes (T2DM) in children. Studies have shown that insulin resistance (IR) to be an independent predictor for morbidity as well as mortality. These serve as a strong stimulus for public health strategies to improve fitness in children and adolescents. Methods to assess IR, improve IR and understand complications are increasingly important in children.
