Sport psychology involves the scientific study of human behavior in sports contexts and the practical application of psychological principles to athletes and sports teams. Some key objectives of sport psychology are to understand how psychological factors influence athletic performance and how sports participation impacts psychological health and development. Sport psychologists employ various mental training techniques to help athletes manage emotions, minimize the psychological effects of injuries or poor performance, and improve concentration, motivation, and goal achievement. These techniques include relaxation, visualization, self-talk, and arousal control.
