Here we examine the acute effects of a single exercise session on cerebrovasculature using a multi-TI arterial spin labelling (ASL) sequence to measure cerebral blood flow (CBF), and a dual-echo ASL sequence with hypercapnia to measure cerebrovascular reactivity (CVR). We show that contrary to previous smaller studies, 20-minutes of aerobic exercise does not affect CBF or CVR in the 60-minute period after exercise. Despite this, changes in CBF after exercise were related to individually-determined systemic physiological changes associated with exercise intensity, informing on moderators of cerebral autoregulation.
