Abstract. Volition is an essential component of sport and exercise. It comprises self-regulation processes complementing motivation to facilitate successful action. Therefore, sport psychological interventions or psychological skills training largely involve volition. Essentially, three theoretical approaches to volition have stimulated sport psychological research: the theory of action control, the Rubicon model of action phases, and the resource depletion model. These three models will be outlined and evaluated with regard to their contribution to sport psychological research. Despite their contributions, research on the exact mechanisms underlying volition is still in its infancy. Based on new developments involving affective neuroscience and self-control success, potential mechanisms are suggested. Subsequently, we discuss how these developments can advance the aforementioned well-established theories.
