Objective of the study was to identify an informative criterion for assessing the functional state of the vestibular apparatus of university students.
Methods and structure of the study. The experiment was run at the premises of the FSBEI of HE "Chuvash State Agricultural Academy" from September through October 2019. Sampled for the study were the 1st-2nd-year (18-20 years old) students (n=58) attributed to the main health group. Each subject gave a pre-experimental written informed consent for the study. The subjects were tested during the physical education classes right after the introductory part.
The functional state of the vestibular apparatus was rated in the common tests of Yarotsky, Bondarevsky, and Romberg.
Results and conclusions. The mathematical processing of the data obtained in the Romberg’s, Bondarevsky’s, and Yarotsky’s tests revealed that it is the Romberg’s test that yields the most informative results. This was evidenced by the comparative analysis of the test results under the normal distribution law (Gaussian distribution), which makes it possible to recommend this test for the practical use in physical education of students when assessing their functional state.
Proceeding from the study findings, in assessing the success of the sports competences mastering process, it is recommended to focus not only on the physical fitness of students but also on the dynamics of the functional test rates. Firstly, this will enable to timely adjust the educational process of sports training. Secondly, this will contribute to the successful development of the psychophysical qualities required for the relevant professions.

Keywords: students, experiment, vestibular stability, sensory system, normal distribution law, coefficient of variation.
