A Conceptual Model for Characterizing Physical Activity

Abstract It is the purpose of this paper to report efforts to construct a model characterizing physical activity as a sociopsychological phenomenon. The work was based upon the assumptions that physical activity can be reduced to more specific components, i.e., a set of all physical activities can be reduced to logical subsets; and that a meaningful basis for such a procedure is the instrumental value physical activity is perceived to have for the individual. A rationale is given for each of the six dimensions of the model. In addition to construct validity, the integrity of the model was assessed by determining the degree of univocality and independence of the postulated subdomains. I
