A physical fitness curriculum, designed to provide cumulative benefits in a sequential pattern, is based upon a framework of a conceptual structure. The curriculum's ultimate goal is the achievement of greater physiological efficiency through a holistic approach that would strengthen circulatory-respiratory, mechanical, and neuro-muscular efficiency. These components of the fitness curriculum are illustrated in the framework by thinking, feeling, and acting components, involving: (1) a knowledge of what physical fitness entails in terms of physiological efficiency; (2) an understanding of the necessity of applying the knowledge of physical fitness in day-to-day life; and (3) a realization of the necessity of movement in physical fitness. The model of this conceptual structure is divided into three parts: physiological concepts, psychosocial concepts, and activities concepts. Diagrams illustrate each of these concepts with accompanying outlines of the subconcepts implicit in each; training results emerging from designated physical activities; and the long-term beneficial physical changes resulting from extended participation.
