Abnormal muscle metaboreflex control of sympathetic activity in never-treated hypertensive subjects.
BACKGROUND Muscle metaboreflex control in hypertensive subjects has not been described yet. We investigated the integrity of muscle metaboreflex control of muscle sympathetic nerve activity (MSNA) and blood pressure (BP) in never-treated hypertensive subjects. METHODS Eighteen hypertensive (42+/-1 years) and 22 normotensive subjects (38+/-1 years) were studied. The MSNA was measured by micron...
متن کاملModulation of arterial baroreflex control of muscle sympathetic nerve activity by muscle metaboreflex in humans.
We aimed to investigate the interaction [with respect to the regulation of muscle sympathetic nerve activity (MSNA) and blood pressure] between the arterial baroreflex and muscle metaboreflex in humans. In 10 healthy subjects who performed a 1-min sustained handgrip exercise at 50% maximal voluntary contraction followed by forearm occlusion, arterial baroreflex control of MSNA (burst incidence ...
متن کاملSkeletal muscle reflex-mediated changes in sympathetic nerve activity are abnormal in spontaneously hypertensive rats.
In hypertension, the blood pressure response to exercise is exaggerated. We demonstrated previously that this heightened pressor response to physical activity is mediated by an overactive skeletal muscle exercise pressor reflex (EPR), with important contributions from its metaboreflex and mechanoreflex components. However, the mechanisms driving the abnormal blood pressure response to EPR activ...
متن کاملComparison of sympathetic nerve activity in normotensive and hypertensive subjects.
A microneurographic technique was used to record multiunit sympathetic activity in skin and muscle nerves of 24 healthy subjects and 21 hypertensive subjects. In both groups, the sympathetic activity recorded during rest appeared in bursts following one of two highly different temporal patterns—one characteristic for muscle nerves and the other characteristic for skin nerves. Muscle nerve sympa...
متن کاملA quantitative study of muscle nerve sympathetic activity in resting normotensive and hypertensive subjects.
Recordings of multi-unit sympathetic activity were made from muscle branches of the peroneal or median nerves in 33 healthy and 12 hypertensive subjects resting in the recumbent position. Simultaneous recordings of intra-arterial blood pressure were made on 17 normotensive and all hypertensive subjects. The neural activity, quantified by counting the number of sympathetic pulse-synchronous impu...
