Of the many people who make New Year’s resolutions, only very few achieve them persistently (Statistic Brain, 2017). This so-called intention-behavior gap extends well beyond the realm of New Year’s resolutions (Sheeran & Webb, 2016) and exemplifies the necessity to not only focus on the processes of goal setting (i.e., motivation) but also on the factors related to goal striving (i.e., volition) (Achtziger & Gollwitzer, 2018; Lewin, 1926). While a large body of research has addressed the motivational processes that enable effective goal setting, the volitional processes that govern the translation of these goals into actual behavior had long been neglected (Gollwitzer, 2012). However, the crucial relevance of volition in sports is intuitively clear: Motivating oneself to sign up for a marathon is considerably easier than actually training for and completing a marathon. In turn, research on volition in sports and exercise has received increased attention since the early 1990s (e.g., Beckmann & Strang, 1991) and this has greatly advanced the field. This Special Issue highlights some of these advancements and explicates promising avenues for further advancing volition research in sports and exercise.
