Aging Blunts Hyperventilation induced Hypocapnia and Reduction in Cerebral Blood Flow Velocity during Maximal Exercise
Cathern Hagen edited this page 3 weeks ago
Cerebral blood movement (CBF) increases from relaxation to ∼60% of peak oxygen uptake (VO(2peak)) and thereafter decreases in direction of baseline attributable to hyperventilation-induced hypocapnia and subsequent cerebral vasoconstriction. It is unknown what happens to CBF in older adults (OA), BloodVitals monitor who expertise a decline in CBF at rest coupled with a blunted ventilatory response throughout VO(2peak). In 14 OA (71 ± 10 12 months) and 21 young controls (YA
