The relationships between age, sex, and exercise intensity on cerebral artery hemodynamics during isometric handgrip exercise

Year: 2024

Type: article

Abstract: The influence of aging and sex on cerebral blood flow responses to isometric exercise are unknown. We observed intensity-dependent increases in velocity of the intracranial arteries, whereas the extracranial artery responses were similarly increased at all intensities during handgrip exercise in young and older individuals. Furthermore, we observed a blunted middle cerebral artery velocity response to handgrip exercise with advancing age, whereas the posterior circulation and extracranial responses were preserved across the lifespan in healthy individuals in males and females alike.
