| Research Abstract |
The central arteries are stiffened and their distensibility decreases with aging. Decrease in central arteries distensibility is one of the risk factors of cardiovascular diseases such as myocardial infarction. It has been reported that exercise improves decrease in central arteries distensibility. However, the effect of water exercise, which is popular in elderly people, on central arteries distensibility has not been investigated so far. Moreover, influence of water temperature to the effect of water exercise has not been unclear. The present study showed that warm water immersion or water exercise in 30°C water temperature had no significant effects on central arteries distensibility, while, water exercise in 38°C water temperature improved central arteries distensibility significantly in elderly subjects.
