In a recent trial, researchers at Yale compared moderate exercise to health education in 1600 participants age 70-89 who were not disabled but were considered sedentary and had some physical disabilities.
The study lasted 3.5 years and the participants were picked because they were unable to walk a quarter mile.
During the 3.5 year period, the research found that compared to the health education program, the moderate exercise program participants had a 25% reduced recovery if they did become disabled and were less likely to become disabled than the other group.
This study further strengthens the argument that exercise not only prevents disability in older adults but shortens their improvement time in case disability or accidents do occur.
