Objective of the study was to define the characteristic features of reflex activity of the central nervous system and statokinetic stability of highly-skilled female single figure skaters with different degrees of manifestation of the "dead point" phenomenon.
Methods and structure of the study. Sampled for the study were 15 highly-skilled female single figure skaters aged 19-23 years with sports experience of 11.5±1.3 years. The study was carried out in standardized conditions in the laboratory of Medico-Biological Support of Training of the Russian National Teams of the Institute for Sports Medicine Research (Sports Medicine Center) of the Russian State University of Physical Education, Sport, Youth and Tourism. The study included questionnaire surveys and interviews, weight, height, and chest circumference measurements, as well as an analysis of the reflex activity of the central nervous system.
Results and conclusions. The study found that the degree of manifestation of the "dead point" phenomenon is related to the length of experience in physical education and sports activities, morphological data, indicators of the breathing capacity and tidal lung capacity, statokinetic stability in terms of the stabilometric tests, psychophysiological characteristics and tension of the regulatory systems of the body when performing competition elements in free skating. The factor analysis results indicated the difference of significant parameters of the functional state in the execution of complex coordination elements by highly-skilled female skaters with different degrees of manifestation of the "dead point" phenomenon.

Keywords: single figure skater, figure skating, free skating segment of figure skating, highly-skilled female figure skaters, "dead point" phenomenon, psychophysiological characteristics, stabilometric tests.
