Final answer:
The goal of sport and exercise psychology is to understand the psychological effects of physical activity, social-psychological factors that influence behavior, and enhance the sport and exercise experience. Predicting long-term outcomes of exercise programs is not a goal.
Step-by-step explanation:
The goal of sport and exercise psychology is to understand the psychological effects derived from participation in physical activity, to understand the social-psychological factors that influence people's behavior and performance in physical activity, and to enhance the sport and exercise experience for those who participate in physical activity. However, predicting the long-term outcome of the participant in continuing an exercise program is NOT a goal of sport and exercise psychology.
