Non-alpha-adrenergic effects on systemic vascular conductance during lower-body negative pressure, static exercise and muscle metaboreflex activation

Aim This study tested the hypothesis that non‐α‐adrenergic mechanisms contribute to systemic vascular conductance (SVC) in a reflex‐specific manner during the sympathoexcitatory manoeuvres. Methods Twelve healthy subjects underwent lower‐body negative pressure (LBNP, −40 mmHg) as well as static hand...
