The article presents the systematization of chronobiological observations of the variability of functional parameters in the involutive-age vector of adaptation of highly trained female body. The systematization was carried out on the basis of the technology of integrated assessment and modeling of adaptive reactions of the main systems in highly qualified athletes aged 16-26 and 37-45. Biochemical, hematological, immunological, rheographic, spirometric, gasometric, ergometric and statistical methods were used for assessment of the functional capabilities of major adaptive mechanisms (nonspecific, hormonal, metabolic, hemodynamic, ventilatory). In order to simulate the functional capabilities in the conditions of threshold loads, an algorithm is proposed, which includes the classification of types of adaptive reactions in the functional profiles of the main systems and conditional visualization of profiles in color resolution. When reproducing the spectral chromaticity of functional models, it is found that in the involutive-age vector the color space of models in the blue spectrum responsible for the weakening of adaptive reactions increases, whereas it decreases in the red spectrum responsible for the amplification and tension of reactions. This indicates a decrease in the response of adaptive systems to the threshold modes of operation when highly qualified athletes reach the age of 37-45, which is characterized by a low degree of preservation of ovarian-menstrual function. The technology of systematization of chronobiological observations of changes of functional parameters of female athletes presented in the article makes it possible to define that in the range of 16-26 years the dominating adaptation mechanism influencing high degree of reaction of the coupled systems to threshold load is hormonal-metabolic. It is its high degree of reactivity during the second half of the ovarian-menstrual cycle causes these athletes a high degree of response of conjugated adaptive systems with a forecast for stress and reduced functions. The weakening of the hormonal-metabolic mechanism in the range of 37-45 years (obviously due to the decrease in reproductive function and cumulative effects) causes a decrease in the response of conjugate systems and a decrease in the price of adaptation to threshold loads in the periods of the menstrual cycle.
