Chernozub A. Adaptive-compensatory reactions of the human body in terms of power loads of different directions

The thesis presents a new way of solving an important scientific problem concerning developing safe mode loads in terms of muscle power orientation. New approaches to power loads estimation methods are suggested taking into consideration the conditions of muscle activity and level of fitness contingent. A further search of informative parameters methods determining the degree of adequacy of training functionalities of those who train and untrained individuals is conducted. A new understanding of the peculiarities of adaptive-compensatory reactions in the human body during power fitness classes is provided in the thesis. In the studies there participated 520 males, among them are: 40 trained individuals engaged in power fitness over the past three years and 60 untrained young people; 400 soldiers aged 22-35 years and 20 employees a special rapid reaction unit. To achieve the objectives, the following methods were applied: morpho-functional (anthropometry, bio-impedansometry, determining the parameters of maximum muscle strength), physiological (heart rate variability analysis), biochemical (enzyme and kinetic) integral method of quantitative estimation of the load in power fitness and informative method of determining the optimal load for soldiers, depending on the specific characteristics of units and the training process. During the research, we have developed an integral method of quantitative estimation of the load, which allowed to quickly determine the power during employment by power fitness training optimal parameters of operating modes depending on the conditions of muscle activity and level of fitness person. Studies of changes in biochemical parameters concentrations of cortisol, testosterone and lactate dehydrogenase activity in serum, in terms of urgent adaptation to the nature of power modes of various levels of intensity and volume, allowed to establish safe (ITNA<0,71) and critical (ITNA>0,95) levels (markers) exercise for the trained and untrained individuals during fitness activities.
