“…An example of domain-specificity relates to children's school schedule, which largely limits their spatial freedom-and thus environmental exposure during weekdays. Separately investigating after-school PA (ASPA) helps to increase our understanding children's context-specific PA and its environmental attributes (Bauman et al, 2012;Ding & Gebel, 2012;Giles-Corti et al, 2005;Stanley, Ridley, & Dollman, 2012;Timperio, Reid, & Veitch, 2015). Studies using subjective measures of ASPA generally reported that boys seemed to be more active after school than girls (Leslie, Kremer, Toumbourou, & Williams, 2010;Pate et al, 1997) and suggested a negative influence of technology-related sedentary activities on ASPA (Atkin, Gorely, Biddle, Marshall, & Cameron, 2008;Pate et al, 1997).…”
