[The metabolic characteristics of the adaptation of athletes to cyclic types of sports to the point of physical loading].

The article considers problems of peculiarities of energetic adaptation of athletics of cyclic sports activity for significant sports loadings by POL indices, antioxidant system. ATP before and after veloergometric test by PWC 170. Adaptation of high class sportsmen for acute and chronic stress was taking place at the expense of more economic consumption of ATP at rest. Optimal indices of energy supply and metabolic adaptation were found at sportsmen with high level of physical state, while a slight disbalance was found at the sportsmen with average level of physical state.
