Exercise intensity alters blood flow to brain after stroke, CPSR study shows

A CPSR study of 13 individuals with stroke (ages 37 to 88) shows aerobic exercise intensity affects blood flow in the brain, also known as cerebral blood flow (CBF).

The study has just been published in the journal Experimental Brain Research.

Designed to measure the impact of a single bout of aerobic exercise on CBF in people with stroke and examine the influence of exercise intensity, the study was funded in part by the CPSR’s Dr. Tony Hakim Stroke Research Innovation Award.

Study participants were between six months and five years post-stroke. Four of the participants had experienced a lacunar stroke, seven had had an ischemic stroke and two had experienced a hemorrhagic stroke.

This is the first study to report acute exercise-related changes in CBF in individuals with stroke. The study found moderate intensity exercise increased CBF in sensorimotor region compared to low intensity exercise.

Study authors include Andrew Robertson, David Crane, Saeed Rajab, Walter Swardfager, Susan Marzolini, Zahra Shirzadi, Laura Middleton, Bradley MacIntosh.
