Changing from supine to a seated position creates an orthostatic challenge due to the effects of gravity on the distribution of blood. This redistribution of volume unloads baroreceptors and may evoke sympathetic activation. The sympathetic activatio

Previous research suggests individuals with intellectual disabilities (ID) may experience autonomic dysfunction, however, this has not been thoroughly investigated. The aim of this study was to compare the autonomic response to standing up (active or

Publikováno v: Joyce, W, White, D W, Raven, P B & Wang, T 2019, ' Weighing the evidence for using vascular conductance, not resistance, in comparative cardiovascular physiology ', The Journal of Experimental Biology, vol. 222, no. March . https://doi.org/10.1242/jeb.197426

Vascular resistance and conductance are reciprocal indices of vascular tone that are often assumed to be interchangeable. However, in most animals in vivo, blood flow (i.e. cardiac output) typically varies much more than arterial blood pressure. When

What is the central question of this study? This study evaluated the following central question: does N-acetylcysteine (N-AC), an antioxidant that readily penetrates the blood-brain barrier, have the capability to reduce the increase in sympathetic n

Caffeine delays autonomic recovery following acute exercise

Publikováno v: European Journal of Preventive Cardiology. 22:1473-1479

Impaired autonomic recovery of heart rate (HR) following exercise is associated with an increased risk of sudden death. Caffeine, a potent stimulator of catecholamine release, has been shown to augment blood pressure (BP) and sympathetic nerve activi
