Acute beta-blockade increases muscle sympathetic activity and modifies its frequency distribution.
BACKGROUND The possible mechanisms by which beta-adrenergic antagonists may act on the neural regulation of the cardiovascular system are still elusive. Recent studies reported a marked increase of postganglionic muscle sympathetic nerve activity (MSNA) after acute beta-blockade associated with unchanged values of arterial blood pressure and baroreflex sensitivity. We tested the hypothesis that...
متن کاملPrevious exercise attenuates muscle sympathetic activity and increases blood flow during acute euglycemic hyperinsulinemia.
Insulin infusion causes muscle vasodilation, despite the increase in sympathetic nerve activity. In contrast, a single bout of exercise decreases sympathetic activity and increases muscle blood flow during the postexercise period. We tested the hypothesis that muscle sympathetic activity would be lower and muscle vasodilation would be higher during hyperinsulinemia performed after a single bout...
متن کاملMuscle chemoreflex increases renal sympathetic nerve activity during exercise.
Activation of the muscle chemoreflex increases sympathetic drive to skeletal muscle in humans. This study investigated whether activation of the muscle chemoreflex augments the renal sympathetic nerve activity (RSNA) response to dynamic exercise in rabbits. The muscle chemoreflex was evoked by hindlimb ischemia during exercise on a motorized treadmill. Seven New Zealand White rabbits performed ...
متن کاملBlockade of AT1 receptors in the rostral ventrolateral medulla increases sympathetic activity under hypoxic conditions.
The role of ANG type 1 (AT1) receptors in the rostral ventrolateral medulla (RVLM) in the maintenance of sympathetic vasomotor tone in normotensive animals is unclear. In this study, we tested the hypothesis that AT1 receptors make a significant contribution to the tonic activity of presympathetic neurons in the RVLM of normotensive rats under conditions where the excitatory input to these neur...
متن کاملAcute exercise modifies titin phosphorylation and increases cardiac myofilament stiffness
Titin-based myofilament stiffness is largely modulated by phosphorylation of its elastic I-band regions N2-Bus (decreases passive stiffness, PT) and PEVK (increases PT). Here, we tested the hypothesis that acute exercise changes titin phosphorylation and modifies myofilament stiffness. Adult rats were exercised on a treadmill for 15 min, untrained animals served as controls. Titin phosphorylati...
