Exercise and Brain Vascular Function

Cognitive Performance Clinical Trial

Official title:
The Effects of Aerobic-based Exercise on Brain Vascular Function in Elderly Men

Clinical Trial Summary

Cognitive performance is negatively related to an impaired glucose metabolism, possibly due to impairments in brain vascular function. Supported by the statement from the American Heart and Stroke Association that physical exercise is one of the most effective strategies to protect against cognitive decline, we now hypothesize that exercise-induced changes in glucose metabolism cause beneficial effects on brain vascular function thereby improving cognitive performance. The primary objective of this intervention study is thus to evaluate in sedentary elderly men the effect of a 8-week aerobic-based exercise program on cerebral blood flow, as quantified by the non-invasive gold standard magnetic resonance imaging (MRI) perfusion method Arterial Spin Labeling (ASL). Cerebral blood flow is a robust and sensitive physiological marker of brain vascular function. Secondary objectives are to examine effects on glucose metabolism using the oral glucose tolerance test and cognitive performance as assessed with a neurophysiological test battery.
