“Benefits of intermittent hypoxia on cardiovascular health”
My primary research interest focuses on determining whether environmental interventions can improve cardiovascular health. The overall objective of my research program is to use brief and repeated bouts of mild hypoxia as a therapeutic intervention to improve oxygen-carrying capacity, vascular function, and glycemic control in clinical populations. In this talk, I will present findings from several studies that were conducted in the Clinical Exercise Physiology Laboratory. I will first talk about our identification of the shortest intermittent hypoxia protocol necessary to increase serum erythropoietin levels in healthy individuals, and about the effect of a single session of this intermittent hypoxia protocol on serum erythropoietin levels and hemoglobin mass in older individuals as well as patients with type 2 diabetes. Second, I will talk about the effect of hypoxic preconditioning on brachial artery flow-mediated dilation following an ischemia-reperfusion injury in young and older adults. Finally, I will present our most recent findings on the effect of rebreathing-induced hypoxia on the response to an oral glucose tolerance test in patients with type 2 diabetes.
