The aim of the study is to highlight the importance of body composition and fat substitution monitoring in the chosen groups of current population concerning actual standard of living and sedentary way of life of common population. The contribution offers information about body composition and fat substitution of current population
(n = 80). For examination of body composition a multifrequency bioimpedance analyser In Body 3.0 was used. The measured data showed higher proportion of relative amount of fat free mass (p<0.01) and simultaneously low proportion of fat mass in individuals regularly exercising in comparison with common population with no exercise in which higher proportion of fat mass means a dangerous risk for their health (p<0.01). The discovered intersexual differences were seen in all observed parameters and were in accordance with available studies when exercising and non-exercising men proved higher values of active mass and lover values of inactive mass than women (p<0.01). In conclusion it is pointed out the importance of observation of the level and changes of body composition in common population and its peripheral groups. It is possible to recommend physical activity as one of possibilities for influencing the proportion of fat mass in the body. Verf.-Referat
