“…Physical activity for all racial, ethnic, age, and gender groups has been shown to reduce the risk of cardiovascular disease, particularly stroke (Goldstein et al, 2006;Sacco et al, 2006). In addition, metaanalytic reviews have provided strong evidence that participation in either nonspecific physical activity or specific aerobic or resistive activities is associated with a variety of health improvements, such as: decreased risk of coronary heart disease and stroke (Cornelissen & Fagard, 2005;Lee, Folsom, & Blair, 2003;Wendel-Vos et al, 2004); decreased progression of degenerative joint disease (Roddy et al, 2005); prevention of osteoporosis of the lumbar spine (Palombaro, 2005); decreased incidence of falls (Chang et al, 2004;Weatherall, 1994); increased gait speed if the activity is of sufficient intensity and dosage (Lopopolo, Greco, Sullivan, Craik, & Mangione, 2006); improved cognitive function in sedentary older adults (Colcombe & Kramer, 2003) and in those with dementia (Heyn, Abren, & Ottenbacher, 2004); a modest benefit in quality of life for frail older adults (Schechtman & Ory, 2001); and a positive association with successful aging (Depp & Jeste, 2006).…”
