Aerobic Exercise Boosts Blood Flow to the Brain in Seniors

In a new study, researchers from UT Southwestern found that when older adults with mild memory loss followed an exercise program for a year, the blood flow to their brains increased.Aerobic Exercise Boosts Blood Flow to the Brain in Seniors

For their research, a team of scientists followed 70 men and women aged 55 to 80 diagnosed with mild cognitive impairment. Participants completed cognitive exams, fitness tests, and brain magnetic resonance imaging (MRI) scans.

The participants were divided into two groups and were randomly assigned to either follow a moderate aerobic exercise program or a stretching program for one year. The exercise program involved 3 to 5 exercise sessions per week, each with 30-40 minutes of moderate exercise such as a brisk walk.

Having analyzed the received data, researchers concluded that those who performed aerobic exercise showed decreased stiffness of blood vessels in their neck and increased overall blood flow to the brain.

The scientists also noted that the more their oxygen consumption increased, the greater were the changes to the blood vessel stiffness and brain blood flow. However, those who participated in the stretching program didn’t show any changes.
