Objective of the study was to develop stabilometric group benchmarks for application at every progress stage in the modern ski jumping and Nordic combined long-term athletic training systems. Methods and structure of the study. The study was sponsored by "Sports - Move to Victory" State Research Grant and run in the period of June 10-15, 2019 at the A.A. Danilov `Snezhinka" Sports Training Center of the Tchaikovsky State Institute of Physical Culture. We sampled for the study 189 ski jumpers and Nordic combined competitors of different ages, genders, qualifications and long-term athletic training progress stages. The sample was tested by Stabilan-01-02 Stabilometer System with a biological feedback capacity in a Tolerance Test mode to obtain the following quiescent-state test rates: eyes-open/ eyes-closed balance function quality test rate; fast redirection postural control test rate; and the Romberg test ratio. Results and conclusions. The stabilometric and motor skills tests and analysis yielded the eyes-open/ eyes-closed balance function quality test rates. Thus when an individual eyes-open balance function quality test rate was higher than the eyes-closed one it was interpreted as indicative of the leading role played by the visual analyzer in the motor skills training process; in an alternative case, the leading role was attributed to the sensorimotor analyzer system, with the progress in motor skills secured rather by muscular sensations. The redirection postural control test made it possible to rate the oscillatory movements in the motor skill execution process i.e. the individual movement control efficiency in the sample. The relatively high oscillatory movement counts were interpreted as indicative of the postural control inefficiency and potential rapid depletion of the bodily energy resource; with the eyes-open and eyes-closed versions of the redirection postural control test making it possible to rate contributions of the visual and sensorimotor analyzer systems, respectively. The study data and analyses made it possible to offer a set of stabilometric group benchmarks (that may be applied to find groups relying on different analyzers in the motor skills mastering and excelling trainings. Stabilometric tests are recommended for application for the progress control purposes in the modern ski jumping and Nordic combined sports as they provide important information on contributions of the analyzer systems in the balance function. Systemic stabilometric tests in the ski jumping and Nordic combined sports at every training stage will help improve the training process efficiency.
