Paper Title
An Applied Study on Effects of Sports on Psychology and Life

Abstract
Physical Education (PE) is a subject where you can take part in and learn about physical activities. You learn about how important keeping fit is for the health of your body and mind.In some activities you work on your own and in others you work with your classmates as part of a team. The epidemiologic study of any concept or event requires that the item under investigation be defined and measured. The common and professional uses of the terms "physical activity," "exercise,"and "physical fitness" reveal a need for clarification.This paper, therefore, defines physical activity,exercise, and physical fitness, with the hope that each definition will provide a framework in which studies can be interpreted and compared.Ideally, standardized terminology will promote greater understanding of the relation between physical activity, exercise, physical fitness, and health. Keywords� Sport, Physical Education, Behavior, Human.
