BACKGROUND During exercise, the sympathetic nervous system is activated and blood pressure and heart rate increase. In heart failure (HF), the muscle metaboreceptor contribution to sympathetic outflow is attenuated and the mechanoreceptor contribution is accentuated. Previous studies suggest that (1) capsaicin stimulates muscle metabosensitive vanilloid(More)
Reflex cardiovascular responses to muscle contraction are mediated by mechanical and metabolic stimulation of thin muscle afferent fibers. Metabolic stimulants and receptors involved in responses are uncertain. Capsaicin depolarizes thin sensory afferent nerves that have vanilloid type 1 receptors (VR1). Among potential endogenous ligands of thin fibers, H+(More)
