Objective of the study of the study is to study the features of the formation of the functional capabilities of energy supply systems for highly qualified ski racers aged 18-20 years in the third year of the Olympic training cycle.
Methods and structure of the study. The work was attended by 11 athletes of the Russian junior national ski racing team aged 18 to 20 years, who participated in comprehensive examinations within the framework of the NMO program conducted on the basis of the ROC Innovation center and the FNC VNIIFK at the beginning and at the end of the preparatory period of the third year (season 2024/25) of the Olympic training cycle (OTS). Two test procedures were used as the "basic" research program: test 1 - stepwise increasing load to "failure" on the Cosmos Quasar Med treadmill (Germany) and test 2 – 60-second maximum muscle load performed according to the "all-out" type on the Monark Peak Bike Ergomedic 894E mechanical bicycle ergometer (Sweden) [1].
Results and conclusions. The obtained results allowed us to establish that the development of the functional capabilities of the main energy supply systems of cross-country skiers in the age range of 18-20 years (compared to adult athletes) in the third year of the Olympic training cycle is characterized by a priority increase in the power capabilities of the lactate energy system, while the power and efficiency capabilities of the oxidative system are further stabilized (at a rate of annual growth). This is manifested in an increase in maximum oxygen consumption and anaerobic threshold levels (in the range of 3.9 to 6.5%), which approach the level of definitive values.

Keywords: cross-country skiing, age period 18-20 years, dynamics of functional capabilities of energy supply systems, readiness for implementation activities.
