Poor nutrition, in addition to an overall lack of exercise, is one of the major issues of the current lifestyle. The basic question needed to be answered when designing exercise intervention: Are the physical assumptions affected by body mass (BM)? The exercise predispositions can be evaluated by the extracellular (ECM) and intracellular (BCM) mass ratio.
To verify the dependence of the ECM/BCM on BM we calculated ECM/BCM for girls (normal BM, N=546, mean age=12.8+-3.7yrs , BMI=19.5+-0.2kg.m-2; overweight, 148, 12.6+-3.2, 24.7+-0.4; obese, 95, 12.9+-3.4, 29.6+-0.6), adult women of middle age (98, 42.3+-4.6, 23.5+-0.6; 84, 42.8+-4.5, 28.4+-0.8; 76, 42.9+-4.7, 32.8+-0.9) and female seniors (18, 69.4+-2.6, 26.6+-0.8; 15, 69.8+-2.5, 29.6+-1.0; 26, 68.9+-2.3, 34.8+-1.2). For the same age, we did not find any significant differences in the ECM/BCM, and non-significant dependence on BM in subjects differing in body mass.
This coefficient ranged from 0.89+-0.02 in adult women with normal BM to 1.11+-0.03 in seniors with overweight. In conclusion: 1.the morphological predispositions for exercise are not dependent on BM in females without regular physical exercise, 2.there do not exist any objective limitations for regular PA realized in the majority of the female population, 3.for successful management of an overweight populous and/or, in the case of individual obesity, it is necessary to influence both the energy intake (diet) and daily energy output (physical activity).
