Examining Physiological Mechanisms Using Environmental Stressors
Featured Topic — Tuesday, April 9, 2019 — 8:30 AM - 10:00 AM — Convention Center, Room W311D
Environmental and Exercise Physiology Section — Chair: Blair D Johnson — Co-Chair: Zachary J Schlader
Cosponsored by J. Appl. Physiol.
The use of pharmacological means to investigate physiological mechanisms in both healthy humans and those stricken with disease is common. Environmental exposures often strain homeostasis, evoking adaptive or maladaptive physiological responses. Thus, exposing humans to certain environmental conditions can complement pharmacological approaches and/or provide novel and insightful information that pharmoacodissection alone cannot. For instance, sojourning to altitude has provided us with mechanistic insights regarding a variety of physiological responses such as cerebrovascular control in healthy individuals as well as pathophysiological or maladaptive mechanisms such as those present in heart failure and sleep apnea among others. The goal of this Featured Topic is to showcase what we call Enviro-dissection. In other words, the use of environmental stressors as a means to elucidate physiological mechanisms in both healthy and diseased populations. Four outstanding abstracts will be selected for presentation along with our Keynote Speaker, Dr. Philip Ainslie, who will give a presentation entitled Hypoxia and the brain: mechanistic insight from elite free divers and high altitude native populations.
