Vascular Health Laboratory

The research interests of our group focus on the links between vascular health, blood flow regulation and muscle function.  Our studies include a variety of techniques aimed at measuring vessel stiffness, vasodilatory capacity, endothelial function, blood flow and autonomic function in both healthy and diseased populations.

Current Projects

The list of projects below are currently in the state of data collection or manuscript preparation.

Peripheral Vascular Function in Parkinson’s Disease
Although it is well established that individuals with PD have autonomic dysfunction that negatively impacts blood flow and blood pressure regulation, it is currently unknown if they also have peripheral vascular dysfunction.  The goal of this current study is to determine if peripheral vascular dysfunction is present in those with PD and, if so, determine if it can be reversed with antioxidant supplementation.

Does stroke induced limb paralysis result in peripheral vascular dysfunction?
It is well established that physical activity promotes vascular health.  Following a stroke a limb can become partially or completely paralyzed limiting the limb-specific physical activity.  The purpose of this investigation is to determine if this physical inactivity results in vascular dysfunction within that limb.

Exercise modalities to improve blood flow in the lower limbs of those with spinal cord injuries.
There are multiple complications associated with spinal cord injuries that could be reversed with improved blood flow and tissue perfusion within the lower limbs.  The purpose of this investigation is to determine the efficacy of passive limb movement and upper body exercise to increase lower limb tissue perfusion in those with SCI and to determine if blood flow and tissue perfusion is moderated by the degree of autonomic control within the lower limbs.

Single-leg cycling: Implications for rehabilitation
Our recent investigation revealed that blood flow to the active limb is much greater during single-leg cycling compared to typical double-leg cycling.  As a result,  the individual can perform at a much greater limb specific workload during single-leg cycling.  This series of investigations is aimed at determining the role that single-leg cycling may have to improve performance and function in both highly trained and diseased populations.
