title: The paradox of sympathetic vasoconstriction in exercising skeletal muscle.
abstract: Is there sympathetic vasoconstriction in exercising skeletal muscle? Although convincing evidence exists that demonstrates vasoconstriction in active muscle, the proposition that the sympathetic nervous system constricts skeletal muscle during exercise poses a paradox, given the robust vasodilation that occurs in muscle during exercise. Ultimately, muscle perfusion is a balance between metabolic vasodilation and sympathetic vasoconstriction.
