Although there has been increased research and clinical attention given to
the effects that physical activity has on quality of life among older adult
s, there is a lack of consistency surrounding the use of this term. As a re
sult, attempts to examine what causes change in quality of life have been l
imited. This article critically reviews the literature on physical activity
and quality of life in older adults. In so doing, attention is given to bo
th quality of life as a psychological construct represented by life satisfa
ction as well as a clinical and geriatric outcome represented by the core d
imensions of health status or health-related quality of life. The literatur
e is also examined to identify potential mediators and moderators in the ph
ysical activity and quality-of-life relationship. Discussion of possible me
diating variables reinforces the important role of perception when consider
ing the beneficial effects that physical activity has on quality of life. F
rom a public health perspective, understanding what may cause change in qua
lity of life has significant implications for the design, implementation, a
nd promotion of physical activity programs for older adults.
