Article

This article provides an overview of physical activity and its association with
function, disability, and quality of life (QOL) outcomes among older adults. The
rationale and the associated onset of chronic disease conditions that influence
function, disability, and QOL is embedded in the "Graying of America". The
literature reviewed in this article yielded 3 general conclusions: (1) there is
an alarming rate of physical inactivity among older adults, particularly those
aging with a disability; (2) there is strong evidence for the beneficial effects
of physical activity on impairment, function, and health-related aspects of QOL
among older adults, but there is less conclusive evidence for positive effects of
physical activity on disability and global QOL; and (3) there is emerging support
for self-efficacy as a mediator of the association between physical activity and
disability, and QOL outcomes in older adults. Researchers should consider
designing and testing programs that incorporate strategies for enhancing
self-efficacy along with the promotion of physical activity as a means of
preventing disablement and improving QOL among older adults. Such work will go a
long way in identifying practical approaches that can be applied for improving
the later years of life and is critical because many Americans will soon be
affected by the aging of adults in the United States.
