Abstract des Autors

Intensification of physical loads is most probably not a factor that strengthens nonspecific adaptability and it does not increase directly body adaptabilities to non-sports loads. Consequently, this ability depends not only on the number of hours of sports classes a week, absolutely not denying its positive effect, in case of modern sedentary way of life of young people. Moreover, the results received prove that urgent reorganizations occur in the body in response to the action of the nonspecific factor, mainly in the system of vegetative regulation, requiring compulsory record while organizing any kind of activity in this period, since the mechanism of reaction to load changes itself when changing the vegetative tone. Thus, the adaptive effect is to be estimated not by the level of sports achievement or growth of single physiological and especially physical indices. In case of this work organized by the university its assessment is to be based on the fundamental indices of the complex state of functional and adaptive abilities and estimation of these indices should be regular, in dynamics. The structure of biorhythm is one of such fundamental indices, which analysis makes it possible to estimate the current state of body adaptabilities and prevents from laying the basis of the long-term forecast, including sport.
