title: Rapid vascular responses to muscle contraction.
abstract: Continuous measurements reveal that muscle blood flow increases within the first second after contraction. The increase in blood flow is attributable to rapid vasodilation as confirmed by direct observations of arterioles within contracting muscles. New evidence suggests that mechanical deformation of the vascular wall during contraction may be a causative factor.
