Abstract
Statement of the Problem: Childhood overweight and obesity are a worldwide problem. Childhood overweight and obesity has major consequences in all stages of life; it is associated with co-morbidities such as glucose intolerance, diabetes, metabolic syndrome and other cardiovascular risks factors at young adulthood. Alongside a range of health problems associated with increased body mass (BM), overweight or obesity is an important limiting factor for realization of PE and qualitative life style. Methods :In study we assess the effect of exercise in children differing in BM. Study was carried out in 98 children with normal BM (age=12.4 ±2.2 years; BM=48.0±3.6 kg; height=157.0±4.8 cm), 68 overweight (12.1±2.0; 61.6±3.0; 157.7±4.5) and 59 obese (12.7±2.6; 71.2±3.8; 155.1±4.2). The mean energy content of exercise/week in normal BM children was 1920 ± 310 kcal, in overweight 1990 ± 230 kcal, and in obese 2260 ± 290 kcal. The exercise was based on walking (82.0±3.1 %) of all movement activities. Results: Relative changes after the imposed movement intervention in %BF ranged from 15.4 in obese to 16.6% in normal BM and in VO2peak from 13.9 in normal BM to 15.7% in obese. In our children are absolute changes in somatic and functional parameters like a result of imposed exercise based on walking substantively and statistically significant. On the contrary, differences in relative terms are insignificant. Conclusions: We may conclude that similar exercise program may invoke the similar BC and functional performance changes in pre-pubertal children differing in BM.
