Dr. Craig Harms' Laboratory Activities
The primary research interests in my lab are to determine the limits of the human cardiopulmonary control system for gas exchange, respiratory muscle pressure development and for ventilatory output across genders in health and in disease through the lifespan. I am also interested in how men and women differ in these responses.
Recent research projects include:
- How prepubescent boys and girls differ in their ventilatory response during exercise and how this response changes from pre- to post- puberty.
- Is there a sex differences in the cardiovascular consequences of the inspiratory muscle metaboreflex
- Deep inspirations attenuate postprandial airway inflammation in non-asthmatic subjects
- Post-prandial exhaled 8-isoprostane responses to meals of varying caloric and fat content in non-asthmatic, insufficiently active men.
- Effect of aging on the inspiratory muscle metaboreflex
The outcomes from these projects will help our overall understanding of how the cardiopulmonary system functions during exercise and help identify limitation in this system in both health and disease.

Dr. Tom Barstow's Laboratory Activities
The primary research interests in my laboratory focus on muscle and cardiovascular responses to exercise, including capillary gas exchange, and on the metabolic and circulatory responses that ultimately lead to fatigue and task failure. We have developed a battery of noninvasive techniques, including breath-by-breath gas exchange, near infrared spectroscopy and vascular ultrasound, with which to examine the coupling of oxygen delivery to oxygen utilization by skeletal muscle during exercise in humans. In addition, we are adapting these noninvasive techniques to examine the macro-and microvascular responses of skeletal muscle during ischemia-reperfusion.
