RESEARCH INTERESTS
My research focuses on the integrative response of the cardiorespiratory and skeletal muscle systems during exercise. At the onset of exercise, energy requirements increase instantaneously and thus muscle metabolism must also increase. This places additional demands on the cardiorespiratory system to increase the delivery of oxygen to exercising muscles and to transport and/or eliminate metabolic by-products, such as carbon dioxide, away from the exercising muscles. My research program examines possible mechanisms that determine the rate at which the exercising muscle and the cardiorespiratory system adapts to the new energy requirements. Additional studies examine the consequences, such as changes in acid-base status, that are often associated with this imbalance between energy requirements and energy supply. Collaborative studies with Dr. Tom Barstow at Kansas State University examining the effects of differing contraction-relaxation cycles on muscle blood flow are on-going. Specifically, we are focusing on the oscillations in muscle blood flow caused by intermittent muscle contractions and the consequences of these on muscle metabolism.
