Sport psychology involves the scientific study of the psychological factors that are associated with participation and performance in sport, exercise and other types of physical activity.
Contemporary sports psychology is a diverse field. Success or failure on the field often depends on mental factors as much as physical ones. Sport psychology is commonly referred to as "sport and exercise psychology," as it is used for team sports as well as individual fitness endeavors.
Sport psychology assumes that goal-setting is the key to motivation. Imagery is the process of improving sporting performance by practicing purely in your mind. To some extent, imagery is superior to physical training because you can train anywhere, any time.
