Dovgich A. Building up the elite weightlifters' preparedness structure in the process of long-term adaptation to physical loading

The object of the research is a structure of elite weightlifters' preparedness at the stage of maximum realization of individual abilities. The subject of the research is interrelations of the elite weightlifters' preparedness structure components and various coordination framework movements' parameters. The methods of the research. The following methods were applied for decision of the set tasks: theoretical analysis, generalization of special literature data, pedagogical experiment, and mathematical statistics. For the research there were used the following tool methods: tensordynamography, registration of dynamic and kinematical parameters of movement (research complex machine REV-9000), tremormetry, hand dynamometry. Scientific novelty of the obtained results is in the fact that for the first time: from a point of view of systematic approach there has been determined a structure of preparedness of weightlifters in various weight categories and qualifications, there have been revealed basic interrelations of its components with the parameters of competitive exercises; it is shown that alongside with the weightlifters' qualification growth there has been occurring a decrease of leading factors which define the sportive performance, prevailing of specific factors; there are found specific peculiarities of muscle provision while speed-strength exercises by the weightlifters in various body states (in-working, stable condition, compensated and non-compensated fatigue); by means of experiments there have been substantiated the criteria and methods for evaluation of reserve abilities of motor functional system and ways of its improvement at elite athletes; there have been developed mathematical models for a structure of weightlifters' preparedness and competitive exercises morphofunctional provision, whose application makes it possible to forecast different variants for achievement of high sport results; there have been determined specific laws in formation of optimal structure of weightlifters' preparednessin the process of long-term adaptation to physical loads.
