“…Clearly, sports performance is also often motivated by approach-oriented motives such as growth, competence, and self-expansion (e.g., Pelletier, Fortier, Vallerand, & Brière, 2001;Vallerand, 2004). Theorists and researchers have considered the interplay of the defensive motivation posited by TMT and the more growthoriented motivation posited by self-determination (e.g., Greenberg, Pyszczynski, & Solomon, 1995;Vail et al, 2012) and have suggested that any given behavior could be driven entirely by defensive concerns, entirely by growth motivation, or by a combination of the two. For example, in the sports domain, an athlete could be motivated entirely to prove worth to self or others, to gain a lasting legacy in the sport, or to enjoy challenging oneself, growing, and becoming the best they can be at the sport, or (probably most often) by a combination of these motivations.…”
