IntroductionThe dynamics of the coach-athlete relationship in youth sports is a very vital part of the sports arena. This topic interests me due to my career as a development coach while dealing with young people. Team performance does not rely solely on the abilities of coaches or athletes. There have been cases where the interactions between coach and player have not been optimal. Indiana coach Bob Knight is universally known for several technical fouls and for being ejected from games several times during his tenure. He is infamous for his horrible character and the harsh manner in which he treated his team members. Although he was often seen as displaying a lack of control and discipline in his dealings with his players, he was nonetheless considered to have had a very successful career (Freidman, 2013). For many years, winning averages were used to dictate the achievements of both players. interacted. It was believed that if a team had more wins than losses, the coach-athlete combination was superb.

The coach's job is to improve the athlete physically, socially, and psychologically, with winning considered only a byproduct of this work (Gillham, Burton, & Gillham, 2013). Gillham, Burton and Gillham (2013) focused on developing a Coaching Success Questionnaire-2 to help assess other aspects of a coach's interaction with their athletes, both within of coach research and development. .....the coach-athlete relationship for optimal athletic performance and how the coach influences this performance. However, the facet of negative interactions must also be considered. A study that examined how emotionally abusive behaviors are used in sport and the negative results they have on the coach-athlete relationship. In this study, emotional abuse was defined as a pattern of deliberate non-contact behaviors by a person in a critical relational role ending in potential harm to an individual's emotional state. This emotional behavior manifests itself in two main forms, expressive and instrumental. The expressive origins of emotional abuse refer to yelling humiliating comments at an athlete out of anger or frustration. Instrumental origins of emotional abuse refer to emotionally abusive behaviors used to achieve a desired end (Stirling, 2013).
