The benefit of stretching along the artery.
Many rehabilitation exercises involve the stretching of bodies. We point out the necessity of the longitudinal stretching in arteries. The efficiency of an arterial system is closely related to the condition of the transverse vibration of the arterial walls or to the magnitudes of the area oscillation in all blood vessels. For a given blood pressure wave, a more elastic arterial wall has larger area oscillation, and therefore a higher efficiency in circulation. Elastic properties of the artery depend on the longitudinal stretching. In vitro experiment on pig aorta confirms that proper longitudinal stretching increases its elasticity and benefits to the circulatory system.
