Changing the Body Composition Parameters in Women of Both Periods of the Mature Age Engaged in Power Fitness

Results of the research on determining impact of experimental models of training in strength fitness on body composition parameters among women aged 21 to 55 years are represented in the article. To perform the task and achieve the aim of the study we have formed two research groups: 1) women aged 21 to 35 years; 2) women aged 36 to 55 years. As a result we have discovered that studied parameters of bioelectrical impedance analysis (BIA) during the usage of proposed models of training for three months show the same dynamics in both groups, but with rather different progression. The body fat index of women aged 21 to 35 years reduced by 7.9% (p <0.05) during the experiment compared with the initial data. This indicator in the group of people aged 36 to 55 years also shown a decline, but only by 3.8% (p <0,05) over the same period of time. This dynamics was also fixed while examining other indicators of the body composition throughout the experiment period. Thus, we can assume that women of the first group consume more energy in these conditions of intense muscular activity in comparison with those of the other group. At the same time, the analysis of the results of the experiment shown that the level of primary adaptation to loads of strength character was higher in the members of the second group regardless of their age and significantly higher initial parameters of body composition.
