Objective of the study was to develop model characteristics for ski jumpers and Nordic combined skiers at various stages of multi-year athletic training based on the analysis of the stabilometric indicators.
Methods and structure of the study. The study involved 189 ski jumpers and Nordic combined skiers of various ages, sexes and skill levels, representing different stages of multi-year athletic training. Their stabilometric indicators were obtained by means of the stabilographic analyzer "Stabilan 01-02". The study was conducted from June 10 to June 15, 2019 at the premises of the Federal Training Center for Winter Sports "Snezhinka" at FSBEI HE Tchaikovsky State Institute of Physical Culture.
Results of the study and conclusions. The analysis of the equilibrium function quality revealed that in the athletes, whose rates of the equilibrium function quality in the test with eyes open were higher than those in the test with eyes closed, it was the visual analyzer that predominated when mastering motor actions. The higher equilibrium function quality in the test with eyes closed indicated the predominance of the sensorimotor analyzer.
The study of the coefficient of a sharp change in the direction of movement suggested that the economic cost of movement in ski jumping and biathlon was affected by various analyzers.
The analysis of the dynamics of changes in the Romberg coefficient made it possible to determine the degree of influence of visual analyzer on equilibrium function quality of the athletes during movements.
In order to improve the quality of interpretation of the stabilometric rates of the ski jumpers and Nordic combined skiers, we determined the model characteristics of equilibrium function quality, coefficient of a sharp change of direction and Romberg coefficient.
The systematic application of the results of stabilometric measurements in the process of sports training of ski jumpers and Nordic combined skiers enables to collect data on the effects of various analyzers of each athlete on the development of complex motor-coordination actions that can be used by coaches to adjust an individual training process.

Keywords: pedagogical control, stabilometry, model characteristics, ski jumping, Nordic combined, multi-year athletic training.
