Does late life physical activity or exercise prevent or minimize disablement? A critical review of the scientific evidence.
American Journal of Preventive Medicine, 25, 129-136.

There is a substantial amount of evidence that physical activity and exercise are beneficial for improving impairments in the elderly population. However, the statement that physical activity late in life plays an important role in minimizing disability levels is controversial. The purpose of this review was to find out if late-life physical activity only plays a role in reducing impairments, or if it also prevents/minimizes physical disability.
