“…Besides the implications childhood sport participation have on sport-specific skills (e.g., creativity; , childhood sport involvement can be important for understanding characteristics that may explain why some players manage to conduct the amount and quality of practice required to reach elite level of performance (Côté et al, 2007;Côte et al, 2009;Durand-Bush & Salmela, 2002). In relation to the purpose of the present study, sport participation has been highlighted as a beneficial setting for the development of self-regulation (Jonker, Elferink-Gemser, Tromp, Baker, & Visscher, 2015), which have been associated with success in the sport domain in general, and in football specifically (Cleary & Zimmerman, 2001;Toering, Elferink-Gemser, Jordet, & Visscher, 2009). Notably, self-regulation refers to the processes where individuals are "meta-cognitively, motivationally, and behaviourally active participants in their own learning process" (Zimmerman, 1989, p. 329), and is argued to be fostered in environments that provides opportunities for complex tasks, autonomous regulation of involvement, cooperation, support, and evaluation, which often is found in sports (Jonker et al, 2015;Perry, 1998).…”
