Regular mental exercises are currently considered an important component of the rehabilitation of various categories of patients with organic brain disorders. The study was carried out with the help of the Russian Internet portal "Chess Planet", which makes it possible to obtain information about persons with disabilities in the course of their sports training. The study involved 28 people with cerebral palsy at the age of 19-27, out of whom 25 were at the stage of sports specialization and 3 people were at the stage of improving sports skills. The study was carried out using the testing method and the method of statistical processing. After analyzing the data obtained, we can talk about the positive influence of the process of mastering the chess game on the psychophysical status of young people with cerebral palsy. This kind of sport increased the level of their sports training, their resistance to stress and steadily improved the general psychosomatic state. Even taking into account the developing decrease in the values of the considered indicators at the control stage of the study, the subjects had an increase of 13.7% in comparison with the preliminary stage of the study.

Aim. The purpose of the study is to determine the systemic directions and priority ways and develop the stages and technologies for technical and tactical training of people with disabilities for achieving the effective results in chess sport in the long-time perspective. Materials and methods. The empirical study of technical and tactical training conducted in 2005–2015 involved 1275 persons at the age from 10 to 72 years with musculoskeletal disorders, hearing or visual impairments. The criteria for assessing the effectiveness of technical and tactical training were diagnostic questionnaires, specialized chess tests, as well as the following psychodiagnostic techniques: the Spielberger State-Trait Anxiety Inventory (STAI); well-being, activity, mood test (“SAN”-test); The Short Form-36; the UCLA Loneliness Scale. Results. The survey revealed the actual factors hindering effective sports training: difficulties in reaching the training sites, lack of information about chess sections and Internet availability. The upward trend in the technical and tactical training (TTT) dynamics is confirmed by the growth of results due to implementing strategy and tactics – up to 31 %; the development of operational thinking – up to 25 %; recent memory – up to 27 %, evaluative function – up to 31 %. As a result of sports training 72 chess players achieved the ranks and titles of The International Chess Federation, including the title of “International Chess Grand Master”. Conclusion. The pedagogical concept realized by a set of standard and innovative means, methods, organizational forms of adaptive TTT along with psychological and pedagogical support and comprehensive supervision allows to effectively transform the intellectual potential of a chess player into a sports result.

game sports are very promising in the modern world. Chess, which is one of the adaptive sports, occupies a prominent place among them. Its great advantage is associated with the absence of the need for the athlete to perform essential motor actions and the achievement of superiority over the opponent in the course of mental efforts. It is of great interest to elucidate the dynamics of the general functional indicators of a young organism with persistent pathology and an organism that has begun to age in the course of playing chess. The process of chess sports training has a pronounced positive effect on the general psychoemotional state of people with cerebral palsy and the elderly, increasing their resistance to psychophysiological stress. Mastering the game of chess increases stress resistance and improves the general psychosomatic state of chess players with disabilities. As a result of chess lessons on all scales of psychophysical qualities, the subjects showed general positive dynamics. In all cases, there was an improvement in "Wellbeing", "Activity", and "Mood" with a decrease in the levels of "Loneliness", "Situational anxiety", and "Personal anxiety".

Adaptive chess sport can strongly stimulate the vitality of the patients and preserve their existing psychophysical potential through the exercise of creative and mental abilities. The effect of adaptive chess is based on the satisfaction of the psychophysical needs of those with weakened health, but preserved cognitive capabilities of the brain. Comparing the results of a questionnaire among middle-aged and elderly chess players with musculoskeletal problems in Moscow revealed a number of problems in the organization of adaptive chess sports. The most important problems were a reduction in the number of sports institutions of additional education and difficulties with the formation of the coaching staff in adaptive chess. The conducted research showed the high efficiency of regular chess trainings in terms of stimulating the chess player's body. Even subjects in the control group showed an increase in the effectiveness of playing chess by 43% in the first group and 93.5% in the second group compared to the preliminary stage of the study.

Low psychophysical activity of persons with pathology of the musculoskeletal system makes it relevant to search for opportunities to increase it. To solve this problem, it seems promising to use the intellectually stimulating and socializing potential of "mental" sports. As the main variant of adaptive sports for people with disabilities of the musculoskeletal system, chess can be used. The research was carried out on the basis of the Russian Internet portal "Chess Planet". The study involved 28 people 19-27 years old with lesions of the musculoskeletal system in the form of infantile cerebral palsy, living in Moscow. Out of these, 25 people were at the stage of sports specialization and 3 people were at the stage of improving sportsmanship. Methods of testing and statistical processing of the obtained data were applied. Based on the results of the study, we can talk about the effectiveness of chess sports training in Russia in persons with impairments of the musculoskeletal system. It turned out to be very effective in terms of building up general chess training and in terms of stimulating sports-significant intellectual skills in persons with signs of cerebral palsy.
