Cerebrovascular Reactivity (CVR) Using a Hypercapnic CO2 Response Test Change Primary · At the Pre-intervention assessment and 12-weeks following at the Post intervention assessment

CVR will be assessed using 5% CO2 challenge while continuously acquiring MR images. This method has been extensively used and is the most suitable vasoactive stimulus. Briefly, the CO2 air (5% CO2, 21% O2 and 74% N2) will be administered via an air bag with a valve to switch between room air and CO2 air in the bag. A mouth piece and a nose clip will be used to achieve mouth-only breathing. A research staff member will be inside the magnet room throughout the experiment to switch the valve and to monitor the subject. Physiologic parameters, including end-tidal (Et) CO2 and breathing rate will b

Sponsor's own description

This proposal will evaluate two brain health measures, cerebrovascular perfusion and cerebrovascular reactivity (CVR), before and after a proven, interval-based, aerobic exercise intervention in older Veterans. The hypothesis is that the 12-week aerobic exercise intervention (Spin) will increase perfusion and improve CVR in brain regions susceptible to age-related decline. This information will inform the impact of exercise on cerebrovascular health which is known to be negatively impacted in aging and implicated in the development of neurodegenerative disease. This information will also aid the investigators' continued efforts of clinical implementation of evidence-based exercise interventions in the local Atlanta VA and surround region.
