“…This major effect of time constraints is plausible because it is hard to make time for sports activities when handling busy work-and private-life schedules with multiple responsibilities and interests. Again, this finding confirms earlier studies indicating time pressure for these population segments (Ettema, Schwanen, & Timmermans, 2007;Bianchi & Mattingly, 2003;Crompton & Lyonette, 2006;Portegijs et al, 2016). Our results did not support the hierarchical proposition of the leisure constraints theory (Crawford et al, 1991;Crawford & Godbey, 1987;Godbey et al, 2010), which states that intrapersonal constraints (physical/psychological and skills/knowledge constraints), and subsequently interpersonal constraints (partner constraints), are more important in determining sports frequency than structural constraints (time, accessibility and sports facility/supply constraints).…”
