Abstract
Obesity is a growing problem in Czech Republic today, as it is in many countries. Alongside a range of health problems associated with increased body mass (BM) is an important limiting factor for realization of regular physical exercise and qualitative life style. Th e study goal was to assess the eff ect of movement intervention in girls diff ering in BM. Study was carried out on 62 girls with normal BM (mean age = 12.6±2.2 years; BM = 47.8±3.0 kg; height = 157.9±4.1 cm), 48 overweight girls (12.6±2.3; 61.9±3.1; 158.4±4.5) and 42 obese girls (12.8±2.7; 72.6±3.6; 157.4±4.0). Body composition was assessed by bioimpedance method using prediction equations that are valid for the Czech child population, functional variables were determined on a treadmill. Th e energy content of weekly movement program for girls with normal BM ranged from 1390 kcal to 2720 kcal (mean 1990±330 kcal) in children with overweight from 1630 kcal to 2380 kcal (1940±240 kcal) and in obese children from 1910 kcal to 2580 kcal (2280±310 kcal). Relative changes in %BF ranged from 15.6% in obese to 16.4% in normal BM and in VO2 peak from 13.9% in normal BM to 15.7% in obese. In girls diff ering in BM have absolute changes in followed parameters like a result of imposed intervention substantively and statistically signifi cant. On the contrary, diff erences in relative terms are non-signifi cant. We can conclude that an exercise program with a similar energy content, form and intensity causes the similar changes in BC and in motor and functional performance in girls, differing in BM.
