The team examined cerebral blood flow in healthy, physically fit older adults aged 50 to 80 years before and after a 10-day period during which they stopped all exercise using MRI brain imaging.

Lead author of the study published in the journal Frontiers of Ageing Neuroscience, Dr. Jerome Carson Smith said: "We know that the hippocampus plays an important role in learning and memory and is one of the first brain regions to shrink in people with Alzheimer's disease."
