Анотація: (English) This study explores the psychosocial mechanisms within the athlete-mentor dyad, aiming to define how systemic martial arts training fosters discipline, reduces deviant behavior and cultivates leadership traits among youth. The research employs a qualitative interdisciplinary approach, integrating sports pedagogy, behavioral psychology and sociological analysis. A system-structural analysis was utilized to model the discipline internalization loop. The empirical base includes a retrospective review of longitudinal case studies of high-performance athletes in boxing and wrestling over a 5-year period, alongside a comparative analysis of global and regional (Ukrainian) youth sports participation trends from 2005 to 2025. The findings indicate that the mentor serves as the primary architect of a hidden curriculum, where the internalization of rigid ethical codes acts as a predictor of both elite competitive success and social adaptation. The application of stress inoculation training demonstrated a strong correlation between the regulation of acute physiological stress and the development of adaptive tactical intelligence. A significant paradigmatic shift was observed in the Ukrainian cohort, where motivation for athletic engagement has transitioned from aesthetic aspirations to functional fortitude as a mechanism of national resilience. The study validates the athlete-mentor as an architect framework, concluding that the integration of hierarchical mimesis and progressive psychosocial overload effectively transforms raw aggression into social responsibility. Martial arts training is thus positioned as a critical institution for developing socially integrated leaders capable of operating under conditions of chronic external stress.
