Professor Harry B Rossiter


Harry Rossiter is a Lecturer in Exercise Physiology at the University of Leeds, a Professor at the David Geffen School of Medicine at UCLA, and an Investigator at the The Lundquist Institute for Biomedical Innovation at Harbor-UCLA Medical Center in Torrance, California. He is a Fellow of The American College of Sports Medicine and The Physiological Society, UK. Harry received a PhD in physiology from the University of London and completed postdoctoral training in respiratory physiology and medicine at the University of California, San Diego.

Harry is a member of the editorial boards of Journal of Applied Physiology, Experimental Physiology and European Journal of Applied Physiology. He contributes to international guidelines for cardiopulmonary exercise testing and for the use exercise testing as an therapeutic outcome.

He teaches cardiopulmoanry exercise testing to international audiances around the world including for the European Respiratory Socetey, American Thoracic Soceity and American Collge of Chest Physicians. He has authored over 100 peer-reviewed papers and 5 book chapters.

He currently conducts clinical and translational research in respiratory physiology and medicine with the goal of improving the lives of patients with chronic disease.

Research interests

Harry's scientific contributions include;

  • the first simultaneous measurements of oxygen uptake and muscle phosphate metabolism during human exercise, elucidating the mechanisms coupling of internal to external gas exchange;
  • the first-in-human demonstration that exercise-induced endothelial progenitor cell mobilization is nitric oxide dependent;
  • the first measurement of single muscle cell oxygen consumption kinetics;
  • the identification that promoting mitochondrial fission in mid-life can extend the healthspan in drosophila;
  • and the development of innovative methods for exercise and fatigue assessment during whole-body exercise in humans.
