The purpose of the work was to study the features of the influence of power fitness programs different in structure and intensity on the morphometric parameters of the body of women of the second period of adulthood. Materials and methods. We examined 50 women aged 36 to 55 years (the second period of adulthood) who had no contraindications for health reasons to power fitness training. To achieve this purpose, the study participants were divided into 2 research groups (A and B), 25 people each. Each of the groups used the proposed program of power fitness training. Anthropometry and bioimpedancemetry methods were used in the course of the 3-month study to determine the peculiarities of the dynamics of morphometric parameters of the body of women of both groups under conditions of muscular activity of different orientation. Results and discussion. In the process of developing an experimental program of power fitness training for women of the second period of adulthood, mainly the whole training management mechanism was aimed at correcting the parameters of intensity of physical activity, which may allow to maximize the energy potential of the body and the level of functionality in general. Thus, the regulation of the value of load intensity was performed due to the following factors: the level of muscle tension was changed by reducing or increasing the duration of the concentric and eccentric phases of movement; the technique of performing the exercise was partially changed due to the amplitude and position of the body in space; the duration of rest intervals between sets was adjusted; the level of complexity of training exercises complexes and their variability was changed. The use of a generally recognized training program in power fitness, which is based on a set of physical exercises on training devices, helps to reduce the parameters of the circumferential body dimensions of women of the second period of adulthood (group A) by an average of 2.7% (p <0.05). A corresponding tendency towards changes, but with less progression, was revealed when monitoring similar indicators of women in group B. The results of bioimpedancemetry, especially during the second and third months of training, show a decrease by 1.4% (p <0.05) in the indicator of body fat mass in women of group B who in the process of doing fitness used the complex of innovative exercises with own body weight. However, in another group of women, we observe an almost imperceptible tendency towards a decrease in the controlled indicator by 0.2% during two months of power fitness training. A corresponding positive tendency towards changes was revealed in the process of step-by-step control over the indicators of active cell body mass in women of both research groups. Conclusion. The results obtained during the course of research prove that even an anaerobic load under the conditions of using a complex of innovative means of power fitness developed on the basis of exercises with one’s own body weight, but with corresponding changes of kinematic, dynamic and rhythmic characteristics of performance technique contributes to the positive dynamics of morphometric indicators almost in the same range as the load of aerobic orientation when using a generally recognized training program in power fitness with a set of exercises on training devices. At the same time, it was found that under the conditions of using the experimental training program, the level of body fat mass shows the most pronounced tendency towards decrease, regardless of age peculiarities
