“…HRS can substitute for HR, perhaps with similar exercise benefits on postural control (Borges, Werneck, Silva, Gandolfi, & Pratesi, 2011; Han et al., 2012) and muscle strength (Mitani et al., 2008; Yoo et al., 2014), even while HRS (vs. HR) reduces the aerobic demand in healthy adults (Shimomura et al., 2009), children (Rigby, Papadakis, Bane, Park, & Grandjean, 2015), and healthy older adults (Kim et al., 2016). Although a previous study reported that older adults showed greater interest in HRS than did younger adults (Kim et al., 2016), the HRS effect on postural control for older adults was not investigated. In the context of this literature and the possibility that HRS might provide an alternative, lower intensity, cost-effective, convenient, accessible, and safe exercise for older adults, we sought to compare the effects of HRS and HR on core muscle activation patterns among healthy younger and older adults.…”
