Within-Day Repeatability Of Cerebral Vasomotor Reactivity To Rebreathing-Induced Hypercapnia: Impact Of A 15 Minute Recovery, Natalia Cardenas, Damsara Nandadeva, Zachary Martin, Paul J. Fadel, R Matthew Brothers
International Journal of Exercise Science: Conference Proceedings
Cerebral vasodilatory responsiveness to elevations in arterial carbon dioxide concentration, termed cerebral vasomotor reactivity (CVMR), is utilized to assess cerebral vascular function and health. An impairment in this response is associated with risk for various cerebral vascular diseases and neurocognitive conditions including stroke, cognitive dysfunction, dementia, and Alzheimer’s disease. One commonly utilized methodological approach to assess CVMR is to induce transient hypercapnia by having the participant rebreathe their own expired air. We recently reported very good within-day repeatability when two trials were separated by 2 hr. However, in research protocols, repeat assessments are commonly separated by a shorter duration (i.e., …

Since the beginning of the COVID-19 pandemic, the use of a face mask in public is recommended when social distancing cannot be maintained to decrease the spread of the virus with many fitness facilities requiring their patrons to wear a face mask during exercise. The physiological response of wearing a face mask during exercise is relatively unknown and is speculated among the media resulting in contradicting messages conveyed to the public PURPOSE: The purpose of this study was to determine if a face mask influenced performance (time to exhaustion), physiological responses (heart rate, oxyhemoglobin saturation and temperature) and subjective measurements …
