Four new studies published in a leading journal this week link exercise with healthy aging, either through reduced risk or slower progression of several age-related conditions or through improvements in overall health in older age, and detail associations between physical activity and cognitive function, bone density and overall health.
All four studies, and an accompanying editorial commentary appear in the 25 January issue of the Archives of Internal Medicine.
In the accompanying editorial, Drs Jeff Williamson and Marco Pahor, of the University of Florida, point out that previous studies have linked exercise to beneficial effects on a range of conditions and diseases, including obesity, diabetes, heart disease, cancer, lung disease, arthritis, falls and fractures, that can hamper older people's ability to get on with their day to day tasks and lead indendepent lives.
They write:
"Regular physical activity has also been associated with greater longevity as well as reduced risk of physical disability and dependence, the most important health outcome, even more than death, for most older people."
And now, they suggest, these four new studies advance the field and help us better understand the "full range of important aging-related outcomes for which exercise has a clinically relevant impact".
