Abstract
Coronary artery disease, hypertension, congestive heart failure, type 2 diabetes mellitus, osteoarthritis, osteoporosis, and cognitive disorders become more prevalent as people age. Besides delaying the onset of many of these conditions, regular exercise may improve function and delay disability and morbidity in those who have them. Further, exercise may work synergistically with medication to combat the effects of some chronic diseases. Special adaptations for older patients include lower-intensity exercise (eg, fewer repetitions), low-impact exercise (cycling, exercise while sitting), and modified equipment (smaller weights, special shoes, loose clothing). Unresolved issues include development of optimal strategies for motivating older patients to begin and maintain exercise programs.
