Flow-Induced Dilation Of Skeletal Muscle Feed Arteries: Relevance To Exercise Hyperemia, Brittni N. Moore, Jeffrey J. Jasperse Dr.
Seaver College Research And Scholarly Achievement Symposium
During exercise, an increase in blood flow to working skeletal muscle is necessary in order to sustain activity for longer than a few seconds. This is accomplished by the dilation of arteries and arterioles feeding the muscle. Arterioles, located within contracting muscle, are exposed to dilatory metabolites released by the muscle; however, the mechanism by which feed arteries dilate is still unknown, since they are located external to the muscle. The purpose of this study was to determine if flow-induced dilation (resulting from shear stress on endothelial cells) contributes to exercise hyperemia in rat extensor digitorum longus and gastrocnemius muscle …
