Sport psychology applies to a broad population base. Although some professionals use sport psychology to help elite athletes achieve peak performance, many other sport psychologists are concerned more with children, people who have physical or mental disabilities, seniors, and recreational participants.
More and more sport psychologists have focused on the psychological factors involved in exercise and health, developing strategies for encouraging sedentary people to exercise or assessing the effectiveness of exercise as a treatment for depression. To reflect this broadening of interests, the field is now called sport and exercise psychology. Some individuals focus only on the exercise- and health-related aspects of the field.
