Abstract

Aging decreases independent daily activity and reduction in physical activity level by decreasing the functional level of the body. Additionally, a sedentary lifestyle has been confirmed as an important risk factor for chronic disease morbidity and mortality. Although many studies have been performed on the inhibition or prevention policy in aging, physical activity has proven the most effective way to improve loss of muscle strength or each organ hypo-function. The purpose of this article is to describe the aging process patterns including four categories: musculoskeletal system, cardiovascular system, mental condition, and brain function and the relationship of these changes to physical functions and exercise. There is encouraging evidence that moderate exercise or physical activity may provide positive effects in four categories: (1) improvement of strength, endurance, flexibility, and balance; (2) increasing the cardiovascular system; (3) alleviating depression and psychological problems; and (4) decreasing dementia and improvement of cognitive function in elderly people. Exercise or regular physical activity ultimately decreases mortality and leads to an increased life span. The implication for future policy in terms of research, study, and training programs are briefly discussed.
