“…Many of the factors listed in Table 2 have been identified in previous research as being relevant to seniors' participation in physical activity more broadly. In particular, the importance of social interaction as a motivator for older people is well recognized (Andreasson et al, 2016;Bampton, Johnson, & Vallance, 2016;Barrett & Smerdely, 2003;Farrance, Tsofliou, & Clark, 2016;Henwood et al, 2011;Lübcke et al, 2012;Rydeskog et al, 2005). Similarly, the relevance of instructor quality (Bethancourt et al, 2014;Burton et al, 2017;Farrance et al, 2016;Lübcke et al, 2012), cost (Barrett & Smerdely, 2003), accessibility (Bethancourt et al, 2014;Lübcke et al, 2012), time constraints (Lübcke et al, 2012;Van Roie, Bautmans, Coudyzer, Boen, & Delecluse, 2015), and the nature of other patrons (Rydeskog et al, 2005) has been noted.…”
