Hemodynamic Analysis of Stretching Effect of the Ultrasound Pulse Doppler

Abstract

The purpose of this study was to biologically clarify the effect of stretching exercise on the hemodynamic of the gastrocnemius. The subjects were the40right legs of40 healthy male students. Under two conditions of stretching and no stretching, the hemodynamics of the popliteal artery were investigated and compared, between the conditions and before and after stretching, using the arterial diameter and blood flow velocity evaluated by ultrasound. No significant difference was found between the conditions in the arterial diameter, but after stretching, a significant increase in the blood flow velocity, suggests the possibility that it temporarily increases the volume of the bloodflowinthemuscle it controls.
