Central arterial distensibility decreases with age-related changes in the arterial wall, and as a result, systolic blood pressure and/or pulse pressure (difference of systolic pressure and diastolic pressure) may increase in the elderly. Systolic hypertension and increased pulse pressure are known to be independent risk factors of cardiovascular and cerebrovascular diseases. Decreased distensibility of the central arteries may also cause the deterioration of circulatory function and physical ability in the elderly. Several studies have shown that central arterial distensibility is increased in athletes, and that daily physical activity is positively related to central arterial distensibility in not only young but also elderly people. It has also been shown that relatively short-term and low-intensity exercise training could improve central arterial distensibility even in the elderly. Thus, physical exercise may have an effect on retarding age-related changes of the central arteries. To establish higher quality of life by preventing cardiovascular and cerebrovascular diseases and by improving circulatory function and physical ability in the elderly, further studies are needed to investigate the detailed mechanism and the appropriate amount and/or intensity of exercise in improving central arterial distensibility.
