Youth sport is an increasingly popular area in modern athletic development systems, especially in countries that invest much in the training of elite athletes at a young age (). Young athletes are subjected to intense training programs, strict competition requirements, and expectations to perform well in most competitive sport settings (; ). Although the stated environments are meant to promote elite performance and international competitiveness, they also generate psychological stress that has a dramatic impact on the mental health and wellbeing of athletes. In this framework, the problem of chronic stress, emotional burnout, and the lack of motivation has become a burning topic in the youth sports community (; ). The given experiences are traditionally interpreted via the prism of Athlete Burnout as a psychological state, which is defined by emotional and physical fatigue, the loss of athletic achievement, and the development of the devaluation of sport (; ).

Over the recent years, sport psychologists have come to the realization of the significance of recovery experiences that incorporate relaxation, mental disconnection with sport-related demands, and participation in restful activities (). The processes assist the athletes in managing stress and ensuring that there is long-term psychological balance in the demanding systems of sport that are demanding.
