Why the study?
Does aerobic activity improve cerebral vasculature in healthy aged subjects?
Does aerobic activity improve cerebral vasculature in healthy aged subjects?
Aerobic activity is associated with improved cerebral vasculature metrics on MRA, suggesting a potential mechanism for healthy brain aging.
May support cerebrovascular benefits of aerobic activity in elderly; hypothesis-generating and requires prospective trials before practice change.
Aerobic activity in elderly subjects is associated with lower vessel tortuosity values and an increase in the number of small-caliber vessels. It is possible that an aerobic exercise program may contribute to healthy brain aging. MRA offers a noninvasive approach to visualizing the cerebral vasculature and may prove useful in future longitudinal investigations.
