Objective of the study was to identify the features of the development of the functional capabilities of the oxidative and lactic acid energy supply systems of ski racers aged 17-19 years at the stages of the annual training cycle.
Methods and structure of the study. The work involved 12 athletes aged from 17 to 19 years, with training experience from 5 to 8 years, qualifications from CMS to MS and who participated in “slice” comprehensive examinations as part of the Russian junior cross-country skiing team. The survey program provided an assessment of the functionality of the main energy supply systems.
Results and conclusions. In the process of work, it was established that a feature of the formation of implementation readiness at the beginning of the preparatory period is the low level of physical performance, due to the low level of power and economization capabilities of the oxidative and lactic acid energy systems. At the end of the preparatory period, a feature of the formation of implementation readiness is a pronounced decrease in the deviation from the model level of physical performance indicators, due, first of all, to an increase in the power and economization capabilities of the oxidative system while maintaining significant differences in the functioning of the lactic acid system.

Keywords: cross-country skiing, age period 17-19 years, functionality of the oxidative and lactic energy systems, intersystem interactions, implementation readiness.
