The role of spontaneous bursts of muscle sympathetic nerve activity in mediating peripheral vascular responses and cardiovascular hemodynamics in resting man
… AT AUTHOR'S REQUEST.] The ability for sympathetic nerve activity to dynamically evoke vasoconstriction is paramount for the regulation of blood flow and blood pressure. However, very little information is available to characterize the influence of spontaneously occurring sympathetic …

The effects of prostaglandin inhibition on the sympathetic and pressor responses to muscular contraction and postcontraction muscle ischemia
… effect of prostaglandin (PG) inhibition on the sympathetic and pressor responses to isometric handgrip (HG) at 40% of maximal voluntary contraction (MVC) to exhaustion and postcontraction muscle ischemia (PC). To accomplish this heart rate (HR), arterial pressure (n=10) and plasma norepinephrine …

Tolerance to Lower Body Negative Pressure: Effects of Sex and Sufentanil
… beat-to-beat blood pressure (finometer), and muscle sympathetic nerve activity (microneurography: radial nerve). Each underwent a double-blinded, randomized crossover study where they received either a placebo or drug on two different trial days. Data for the first study were obtained solely …

Cardiovascular Risk Indicators and Health-Related Quality of Life in Women Veterans with PTSD
… (resting heart rate, blood pressure, and muscle sympathetic nerve activity) and physical and mental health-related quality of life (SF-36) in a sample of women veterans with PTSD to a sample of nonveteran women without PTSD. In addition, hierarchical multiple regression analyses were used …

Arterial Baroreflex Regulation of Sympathetic Discharge During Maximal Voluntary End-Inspiratory Apnea
The sympathetic nervous system (SNS) increases sympathetic outflow during physiological stress to maintain blood pressure (BP) homeostasis. The arterial baroreflex represents a critical mechanism regulating sympathetic outflow during rest and physiological stress. Volitional apnea, seen in …

Single Nucleotide Polymorphisms of the ATP1a2 gene and Their Effects on Blood Pressure and Other Cardiovascular Variable in African Americans and Caucasian Americans
… Responses of blood pressure, 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 role of the muscle metaboreflex in patients with chronic disease
Exercising muscle needs a constant supply of oxygen for the aerobic metabolism of carbohydrate and fat, and regulation of the blood supply to muscle during exercise is therefore critical. Heart rate, stroke volume and minute ventilation all increase during exercise, and sympathetic vasoconstriction …
