• This feature article emphasizes the need for physical activity and exercise interventions to be developed and delivered in accordance with psychological theory. Pulling from a contemporary theory of human motivation called Self-determination Theory, this article demonstrates how delivering an exercise message, consultation, or program in an autonomy-supportive, well-structured, and interpersonally involved way may benefit participants' attempts to become and stay more active. Practical strategies that may be used by a health and fitness professional to create an autonomy-supportive, well-structured, and interpersonally involved exercise environment also are presented.
This article demonstrates how theory-based strategies may be utilized by a health and fitness professional to deliver exercise messages, consultations, or programs in a way that benefits participants' attempts to regularly engage in physical activity and their well-being.
