A theoretical extension of the concept of energy through an empirical study.

A theoretical extension of the concept of energy through an empirical study This paper extends the concept of energy as a multifaceted concept of the experience of energy and proposes a theoretical model regarding the understanding of the experience of energy. The hybrid model of concept development (Schwartz-Barcott and Kim, 2000) was used in a qualitative empirical study with a sample of athletes and chronically ill individuals. The concept of energy presented is a global concept and can be placed within the much-discussed concept of fatigue. Focusing on energy implicates a resource approach to individuals experiencing fatigue. A theoretical model for the experience of energy emerging from this study includes the subconcepts of the feeling of energy, perceived energy capacity, energy management, and performance of activities. Two sets of strategies within the concept of energy management are identified as energy economizing and energy generating. This article explores the potential of the concept of energy in describing fatigue as a health problem. Implications for clinical practice and further theoretical development are suggested.
