Abstract
is a growing problem over the world. The cause of the overweight and obesity increase in the present population is energy intake non-adapting to its issue. In western countries an energy intake has stagnated over the past two decades, the energy expenditure for the same period drop down by 30%. The study goal was to assess the effect of movement intervention in girls differing in the BM. Study was carried out in 82 girls with normal BM (mean age=13.2±2.9years;BM=45.3±2.7kg;height=157.5±4.0cm; %BF=21.8±2.4%, VO2peak=42.3±2.6ml.kg-1.min-1), 59 overweight girls (13.4±2.7; 54.0±3.0; 159.3±3.1; 26.6±2.7%, 36.1±2.2) and 41 obese girls (13.3±3.0; 64.2±4.1; 159.6±3.4; 30.5±3.1%, 30.6±2.2). Body composition was assessed by bioimpedance method using prediction equations that are valid for the Czech girls, functional variables were assessed on a treadmill. The intervention was on intensity ranged from 75 to 85% of HRpeak, and exercise duration was 9 weeks. The energy content of weekly movement program for boys with normal BM ranged from 1450 kcal to 2650 kcal (mean 2050±330 kcal) in overweight from 1591 kcal to 2390 kcal (1990±290 kcal) and in obese from 1680 kcal to 2290 kcal (1986±330 kcal). Reduction in %BF ranged from 13.9% in obese to 15.0% in normal BM of starting value, ECM/BCM relationship decreased from 11.9% in subjects with normal BM to 13.2% in obese, and in VO2peak increased from 14.9% in normal BM to 15.8% in obese. In girls differing in BM are absolute changes in adiposity and aerobic fitness like a result of imposed movement intervention substantively and statistically significant. On the contrary, differences in percentages of pre-intervention values are non-significant. We can conclude that an exercise program with a similar energy content, form and intensity causes the similar changes in adiposity and in motor and functional performance in girls, differing in BM.
