Research Areas

Dr. Villar's research focuses on determining the underlying mechanisms involved in the cardiovascular, respiratory, and muscular integrative regulation to physiological challenges. More specifically, he uses postural changes and exercise as a framework to elucidate the role of perfusion pressure, O2 availability, and vascular conductance/resistance in the regulation of blood flow and O2 uptake and the implications for the muscular system especially the muscle pump.

  • Control and regulation of blood flow, oxygen uptake and muscle metabolism during exercise
  • Acute and chronic cardiovascular and respiratory adaptations to exercise and environmental challenges
  • Effects of aging and chronic disease on the integrative cardiovascular and respiratory responses to exercise
  • How sex plays a role in the integrative cardiovascular and respiratory responses to exercise
  • Blood flow
  • Oxygen consumption
  • Chronic diseases
  • Exercise
  • Postural changes
  • Sex differences

Courses

  • Advanced Exercise Physiology (KIN 4470)
