Introduction. Russian scientific publications show the great importance of physical education and sports as a means of social adaptation of people with disabilities, but there is a shortage of research in the field of the influence of badminton classes on the social adaptation of schoolchildren with intellectual disabilities, despite the fact that badminton has great opportunities in the field of social adaptation. The purpose of the article is to study and specify the relationship between badminton classes and indicators of social adaptation of schoolchildren with intellectual disabilities. Materials and methods. The study is based on materials of a survey of a group of schoolchildren of “School No. 1 of Yoshkar-Ola” using methods of pedagogical observation, documentation analysis, psychological testing and sociometry. To analyze the data, we used the calculation of correlation coefficients (Pearson) between indicators of badminton classes and indicators of social adaptation of schoolchildren with intellectual disabilities. Research results, discussion. Based on the correlation analysis, statistically reliable data were obtained on the presence of directly proportional relationships between the experience of badminton and the success of competitive activity on the one hand, and the level of development of communicative inclinations and sociometric status, on the other, in a group of schoolchildren with intellectual disabilities. These results were confirmed by pedagogical observation data. On the basis of the results obtained, a number of methodological recommendations were formulated concerning the organization of badminton classes for schoolchildren with intellectual disabilities as a means of their social adaptation. Conclusion. The study proved a statistically reliable relationship between the indicators of badminton classes and the indicators of social adaptation of schoolchildren with intellectual disabilities: the longer students practice badminton, the more they win competitions, the better their communication abilities are developed and the higher their status in the peer group.
