Sympathetic vasoconstriction in active skeletal muscles during dynamic exercise.
Studies utilizing systemic administration of alpha-adrenergic antagonists have failed to demonstrate sympathetic vasoconstriction in working muscles during dynamic exercise. The purpose of this study was to examine the existence of active sympathetic vasoconstriction in working skeletal muscles by using selective intra-arterial blockade. Six mongrel dogs were instrumented chronically with flow ...

Sympathetic vasoconstriction in working muscles during dynamic exercise has been demonstrated by intra-arterial administration of α1-adrenergic antagonists. The purpose of this study was to examine the existence of α1- and α2-adrenergic receptor-mediated vasoconstriction in active skeletal muscles during exercise. Six mongrel dogs were instrumented chronically with flow probes on the external i...

Sympathetic vasoconstriction in the skeletal muscle vascular bed is essential for the regulation of vascular resistance and therefore control of blood pressure and muscle blood flow at rest and during exercise. I...
متن کاملDifferential sympathetic outflow and vasoconstriction responses at kidney and skeletal muscles during fictive locomotion.
We compared sympathetic and circulatory responses between kidney and skeletal muscles during fictive locomotion evoked by electrical stimulation of the mesencephalic locomotor region (MLR) in decerebrate and paralyzed rats (n = 8). Stimulation of the MLR for 30 s at 40-microA current intensity significantly increased arterial pressure (+38 +/- 6 mmHg), triceps surae muscle blood flow (+17 +/- 3...
