Fig. 5From: Progressive arteriolar vasoconstriction and fatigue during tetanic contractions of rat skeletal muscle are inhibited by α-receptor blockadeRelationship between arteriolar baseline diameter and sympathetic vasoconstriction during fatigue in 4-ms pulse duration condition. The line indicates the relationship between arteriolar diameter and vasoconstriction after the 10th set of contractions (r = 0.752, *P < 0.05)Back to article page
