Introduction

In the process of life, all analyzers do not function in isolation, but in continuous interaction with each other. This is necessary for a normal perception of the surrounding world (Azhippo, Kuzmenko, 2015; Shesterova, 2015). At the same time, the vestibular sensory system plays an important role in the interaction of other sensory systems (Kuzmenko, 2011).

A high level of the functional state of the human body is ensured by the perfect activity of the vestibular sensory system. It plays an important role in the formation of visual-spatial representations, motor skills and skills; motor management; development of motor skills; maintaining the balance of the body at rest and during movement; coordination of movements at rest and in the process of motor activity; orientation in space with active and passive movement. The vestibular sensory system provides the perception of information about acceleration or deceleration arising in the process of rectilinear or rotational motion, as well as when the position of linear and angular movements of the body and head in space changes (Yermakov, Yakunin, 2000; Solodkov, Sologub, 2008; Horlings, Kung, Bloem, Honegger, Van Alfen, Van Engelen, Allum, 2008; Rynkiewicz, urek, Rynkiewicz, Starosta, Nowak, Kitowska, Kos, 2010; Kuzmenko, 2011; Markova, Repš, 2013; Maslyak, 2015; Rovny, Ilyin, Lizogub, Rovnaya, 2015).

Children with visual impairments low stability of the vestibular analyzer is observed when exposed to various accelerations, turns, bends, coordination of movements, balance, orientation in space are significantly impaired, the ability to maximize the manifestation of motor qualities decreases (Demchuk, 2016).

Solodkov, Sologub, 2001, revealed that the normal development of this function is completed by the age of 14, and in children with visual impairments it continues to take shape until the age of 17.

The issues of changing the functional state of the vestibular sensory system under the influence of specially targeted exercises and outdoor games in healthy children were: Moiseenko, 2014-for preschoolers; Maslyak, 2007, 2008, 2015-for primary school children; Shesterova, 2002, 2004, 2008; Kuzmenko, 2010, 2011, 2013; Kuzmenko, Shesterova, 2011, 2012-among middle school schoolchildren; Maslyak, Shesterova, Kuzmenko, Bala and al., 2016 - among primary and secondary school schoolchildren; Rovny, 2001 - for volleyball players. Experts have identified their positive effect on the indicators of the functional state of the vestibular analyzer.

The influence of physical exercises and outdoor games on the functional state of the sensory systems of children with visual impairment of preschool and school age is devoted to the work of Lyakh, 1987; Matvova, 1991; Makarenko, 2000; Myasnikova, 2005; Osipova, 2010; Sedova, Shesterova, 2013; Ordinary, 2015, etc. At the same time, an insignificant amount of research has been revealed on the effect of specially directed exercises and outdoor games on the functional state of the vestibular sensory system of middle-school schoolchildren with visual impairments. All of the above led to the relevance of the problem being studied.

Purpose of the work is to determine the effect of specifically aimed exercises and active games on the indicators of the functional state of the vestibular analyzer of 10-16-year-old schoolchildren with visual impairments.

Materials and methods

Research methods: analysis and synthesis of scientific and methodological literature, determination of the stability of the vestibular analyzer to rotational loads, pedagogical experiment and methods for statistical processing of results.

The stability indicators of the vestibular analyzer were investigated by the results of deviations in walking before and after rotational loads in the Barani chair. The subject was asked to stand with his eyes open to face the line drawn 5 m from the object, then close his eyes with a bandage and walk to the object. …
