摘要：Poor nutrition, in addition to an overall lack of exercise, is one of the major issues of the current lifestyle. The most common consequence is the increase in overweight and obesity and decrease of physical fitness. The basic questions needed to be answered when designing exercise intervention: Are the physical assumptions affected by overweight or obese state? The exercise predispositions can be evaluated by the extracellular (ECM) and intracellular (BCM) mass ratio. To verify the dependence of the ECM/BCM on body mass (BM) we calculated ECM/BCM for girls (normal BM, N=1598, mean age=12.8±3.6yrs, BMI=19.5±0.2 kg.m-2; overweight, 178, 12.6±3.2, 24.7±0.4; obese, 219, 12.9±3.4, 29.6±0.6), and in boys (normal BM, N=1810, mean age=12.9±3.9yrs, BMI=19.9±0.3 kg.m-2; overweight, 253, 1286±3.2, 24.9±0.4; obese, 242, 12.9±3.4, 30.3±0.6) differing in BM. We did not find significant differences in the ECM/BCM in girls and the same in boys, and non-significant dependence on BM. In conclusion: 1. the morphological predispositions for exercise are not dependent on BM, 2. do not exist any objective limitations for regular exercise realized in the children, 3. for successful management of an overweight and/or obesity, it is necessary to influence both the diet and exercise.
