Glenn Stewart, PhD

Glenn Stewart is a Research Associate in the Department of Cardiovascular Diseases at Mayo Clinic and his research interests focus on heart and lung interactions during exercise. Since completing his doctorate at Griffith University in Australia, where he studied the effects of endurance exercise training on cardiac function, Glenn has been working on a number of invasive and non-invasive cardiopulmonary projects which incorporate novel echocardiography and gas exchange techniques to better understand right ventricular-pulmonary interactions in health and disease. Glenn’s current projects include examining complex cardiopulmonary interactions in patients with heart and lung diseases, as well as assessing cardiac and pulmonary adaptability in healthy individuals exposed to high-altitude and extreme exercise and environmental conditions. Glenn is presently an American Heart Association Fellowship Awardee, and recently received a Career Development Award in Cardiovascular Disease Research Honoring Dr. Earl H. Wood for his current research activities. These include collaborations with the Ultra Sport Science Foundation, Mayo Clinic and the International Trail Runners Association, where a team of scientists are assessing heart and lung physiology of ultra-marathon runners at the Hong Kong 100 (HK100) and the Ultra Trail Mont Blanc (UTMB). This research is aimed at enhancing our understanding of acute cardiopulmonary adaptations to ultra-endurance exercise coupled with high-altitude or sea level air to help inform relevant organizations and governing bodies about exercise prescription in these environments and help guide athletes with their training and preparations for ultra-endurance sporting events.

Guillaume Routier

Guillaume Routier holds a PhD in sociology and is currently a lecturer in sociology of sport at the University of Lyon 1 and a member of the Laboratory on Vulnerabilities and Innovation in Sport (L-VIS). His research focuses on the motives and modalities of participation in sport as well as the career dynamics that lead to it. Thus, in a quantitative and socio-cultural approach, he analyses the interest in sport of different populations on the basis of national surveys. In a more qualitative and interactionist approach, it also analyses the careers of individuals (engagement and disengagement) in sport or dangerous physical activities.

Rémy Hurdiel, PhD, MCF STAPS

Expert in sleep diprivation and fatigue
I study the interactions between sleep, physical activity and cognitive fatigue in athletes, elite and amateur, practicing ultra endurance competitions (solo sailing, ultramarathons, polar expeditions etc...). Several of our publications have shown that in this type of activity, lack of sleep leads to risks for performance, health and safety. How to anticipate? How to manage? Can we adapt to such stress constraints for the body? Where are the limits?
