Outline of Final Research Achievements

Age-related decrease in central artery compliance and cerebral blood flow are associated with increase in a risk of dementia. Aerobic exercise has a favorable effect on vascular and cognitive aging. The aim of this study was to investigate that the effect of exercise training on central artery compliance, cerebral blood flow, and cognitive function. A total of 33 middle-aged and older were assigned to the exercise and the control group. Before and after 8 weeks intervention, we measured carotid arterial compliance, oxygenated hemoglobin (oxy-Hb) in prefrontal cortex, and executive function. There are significant ameliorations in carotid arterial compliance, oxy-Hb, and executive function in the exercise group. Exercise training may increase arterial function and cerebral blood flow, and enhances executive function in middle-aged and older adults.
