| Outline of Final Research Achievements |
Stretching is used to be considered as warming-up exercise. However, it is reported that stretching restrains sympathetic activity and has potential to decrease afterload on the heart. Afterload reduction is more beneficial to elderly whose elasticity of aorta is increased. However, there are few papers which measured afterload directly. Effective arterial elastance (Ea), is an integrated parameter of arterial resistance and compliance. By using ultrasonic methods, we measured noninvasively Ea before and after stretching for two month and evaluated the effect of stretching on Ea. After stretching program, Ea was reduced in the elderly group whose daily activity was low. We concluded that act of promoting stretching is required to elderly who cannot do daily exercise.
