Dynamics of Athletes' Social Adaptation within the Sports Training System: Transformation of Roles and Functions of Social Environment Entities

Abstract

Abstract. Objective. The study aims to provide a systematic substantiation and development of a content matrix regarding the functions of social environment agents (family, coach, teachers, friends) in the process of upbringing and social adaptation of an athlete. This matrix is structured according to the stages of the long-term athlete preparation system by V. Platonov. Particular attention is paid to the transformation of the roles of social agents from the beginning of sports activities to the completion of a professional sports career. Methods. A complex of empirical and theoretical methods was applied: an analysis of scientific literature allowed for the integration of H. Tajfel’s social identity concepts and S. Jowett’s 3Cs model into the domestic discourse. Comparative analysis revealed differences in the functions of primary and secondary socialization agents depending on the level of athletic mastery. A systems-ecological approach and modeling methods were used to create a social support architecture within the PAC triad (parents-athlete-coach) at each stage of the athletic career. Results. It was established that the social environment functions as a multi-level protection mechanism where the roles of subjects shift according to the "communicating vessels" principle. In stages I–III (according to V. Platonov), the family dominates, providing the emotional foundation and logistics. During the stages of maximum realization (stages V–VI), strategic leadership shifts to the coach, while the family becomes the "emotional rear." The roles of teachers and "civilian" friends are detailed as agents of comprehensive development that prevent the personality from being confined within the "insulating bubble" of the athletic role. In the stages of sports career termination (stages VII–VIII), a reverse drift of support priority back to the family was recorded, compensating for the loss of status. It is proven that successful adaptation directly depends on the availability of alternative social roles, which is confirmed by the athletes' experiences. Conclusions. Social adaptation is the result of synergy between the subjects of the PAC triad. The coach must evolve from a "result constructor" to a life mentor, initiating the development of reintegration strategies even at the peak of the athlete's career. The practical value of the work lies in the developed activity matrix, which coaches can use to create personalized support programs. Social support is defined as a strategic asset that ensures the long-term mental health of the athlete after retirement from sports.
