Health benefits of physical activity
Physical activity greatly benefits the health of older adults. The link between the built environment and its influence on physical activity and health has been recognized as an important issue of public health (Carlson, Aytur, Gardner, & Rogers, 2012; Kaczynski, Potwarka, Smale, & Havitz, 2009; Winters et al., 2014). Physical activity improves and strengthens the physical and mental health of older adults, thus it is one of the key strategies of active aging (World Health Organization, 2007; World Health Organization, 2002).
