ABSTRACT
When used in connection with the human organism, the term physical means a concern for the body and its needs. The term activity derives from the word “active,” one meaning of which is the requirement of action. Thus, when the two words physical and activity are used together, the term implies body action. This is a broad term and could include any voluntary and/or involuntary body movement. When such body movement is practiced for the purpose of developing and maintaining physical fitness, it is ordinarily referred to as physical exercise. This chapter discusses both the broad area of physical activity and the more specific area of physical exercise, and takes into account how these factors are concerned with health and how they relate to stress.
