Moderate Walking May Improve Functions of Brain in Senior Adults
According to a small study by the Canadian team, a moderate walking regimen can reduce the symptoms of mild cognitive impairment connected to poor blood vessels in the brain.
To complete their study, a team of scientists randomly divided 38 older adults with mild vascular cognitive impairment (VCI). One group had one-hour walking classes every week for 6 months, while another group did not perform any additional tasks to their everyday activity.
Participants in the training group had significant improvements in their reaction times on the cognitive tests and demonstrated changes in their brain activity that made them resemble healthy brains more.
Senior author of the study Teresa Liu-Ambrose, a researcher with the Aging, Mobility, and Cognitive Neuroscience Lab at the University of British Columbia, says: “While more research is needed to better understand how it brings about its benefits and what factors may impact the degree of benefit observed, there is minimal negative consequence of exercising.”
