The role of spontaneous bursts of muscle sympathetic nerve activity in mediating peripheral vascular responses and cardiovascular hemodynamics in resting man
… of resting muscle sympathetic nerve activity (MSNA) bursts to determine: 1) their influence on leg and forearm vascular conductance as well as on conduit artery diameter in resting young healthy men. We demonstrate that spontaneous MSNA bursts exert a robust and dynamic vasoconstrictor …

Effects of Modest Weight Gain on Blood Pressure and Sympathetic Neural Activity in Nonobese Humans
… on muscle sympathetic nervous system activity (MSNA) in healthy, lean, normotensive individuals. We hypothesized that modest weight gain would increase MSNA in these individuals, and that this neural activation would be accompanied by increases in blood pressure. Concordant with this hypothesis, …

Cardiovascular Consequences of Estrogen Deficiency: Studies in Premenopausal Women
… (HRV), muscle sympathetic nervous activity (MSNA), and serum renin-angiotensin-aldosterone system (RAAS) components. Study one examined the effects of a single bout of dynamic exercise on vascular function in ExFHA (n=12), ExOv (n=14), and SedOv (n=15) women. Pre-exercise, calf BF and BA …

Arterial Baroreflex Regulation of Sympathetic Discharge During Maximal Voluntary End-Inspiratory Apnea
… increases in muscle sympathetic nerve activity (MSNA) and BP. The use of apnea aimed to provide insights into how the maximal voluntary end-inspiratory apneas influence sympathetic action potential (AP) discharge and recruitment patterns in humans, contributing to a better understanding of the …

Single Nucleotide Polymorphisms of the ATP1a2 gene and Their Effects on Blood Pressure and Other Cardiovascular Variable in African Americans and Caucasian Americans
… heart rate, muscle sympathetic nerve activity (MSNA) and systematic vascular resistance (SVR) to pressor stimuli of two difference origins (cold pressor and hypoxic apnea) were tested in 37 individuals. Endothelin function was tested using ultrasound imaging of the brachial artery. Six SNPs were …
