Members: Scientific Committee

Martin Hoffman MD, FACSM

Dr. Marty Hoffman is Professor of Physical Medicine & Rehabilitation at the University of California Davis, and Chief of Physical Medicine & Rehabilitation at the VA Northern California Health Care System. He is also a Founder of the Ultra Sports Science Foundation, a non-profit organization focused on the enhancement and distribution of scientific and medical knowledge related to participation in ultra-endurance activities. He has published over 150 original scientific papers, mostly related to applied exercise physiology with focus on human locomotion, human performance and proper hydration during prolonged exercise. His clinical work has involved cardiac rehabilitation, musculoskeletal medicine and sports medicine. He is a Fellow of the American College of Sports Medicine and serves on multiple editorial boards. He has been a competitive cross-country skier or distance runner for most of his life, and still enjoys exploring his own limits…..though at a much slower pace than in the past.

Patrick Basset, MD

Doctor Anesthesiologist practicing in operating room and in French mountain rescue, specialized in the medical supervision of ultra-endurance sports in hostile environments. Medical Director of Dokever: a medical aid company that coordinates all the means of relief in hostile environments or not, for mass sports meetings or not.
Medical Director of the Paris Marathon of the UTMB of the Etape du Tour de France for more than 10 years. Field doctor first.
Medical research and its financing have become a priority to improve scientific knowledge in order to professionalize these universes and protect the health of athletes. It does so thanks to the Presidency of the Medical Committee of ITRA (International Association of Trail Running) and a Franco-American Foundation: Ultra Sports Science.

Ricardo JS Costa

Dr. Ricardo Costa is an academic, researcher, consultant and practitioner in sports dietetics and extremes physiology, based in the Department of Nutrition & Dietetics at Monash University, Australia. His publication outputs, in exploratory field and laboratory controlled intervention research, includes focus on the nutritional and hydration status in ultra-endurance running, physiological responses to ultra-endurance in the heat, impact of endurance exercise on the immune system and nutritional counter-measures, and the impact of endurance exercise (with and without heat-stress) on gut health including prevention and management strategies. As a sports dietetic practitioner, he has provided nutritional support in a variety of sports (i.e., teams, aquatic, combat, endurance, ultra-endurance, adventure and expedition) ranging from junior development to veteran athletes, and from recreational to world championship and Olympic athletes. Before entering a career in academics he was a professional trialthlete/duathlete competing on the World and European circuit between 1994-2003.

Volker Scheer MD, MRCGP, MECOSEP

Volker qualified in Medicine from the University of Munich, Germany. He trained and qualified as a General Practitioner in Edinburgh, UK and as a Sports Physician at the Olympic Training Centre at the University of Heidelberg, Germany.He worked as a SEM consultant and assistant professor at the Sports Medicine Department at the University of Paderborn, Germany. He is now medical lead for the rehabilitation unit for the British Forces in Germany and professor at the UDIMA University in Madrid, Spain. He regularly works for the European Golf Tour and has recently worked at the Olympic Games 2016 in Rio de Janeiro and Athletics World Championships in London 2017. He is founding member of the Ultra Sports Science Foundation.
He has published several scientific papers examining the impact of exercise on the human body, especially in ultra endurance sports and trail running.
In his youth he was a competitive sprinter at national level.

Grégoire Millet

Grégoire Millet is Professor of Exercise Physiology at ISSUL (Institute of Sport Sciences) in Lausanne, the “Olympic Capital”.

H-index = 54. Number of citations = 900.

He has published more than 350 articles including 240 scientific articles in peer-reviewed indexed journals, over 40 book chapters and 4 books on endurance or altitude training.
He is the Chief Editor of “Frontiers in Exercise Physiology” and is regularly invited to conferences World-wide.

His main research topics are: (1) Physiological responses to exercise in hypoxia; (2) Optimization of interval-training; (3) Mechanical / Physiological coupling in sport locomotion; (4) Analysis of fatigue (Neuromuscular and Heart Rate Variability); (5) Ultra-endurance.

He is currently collaborating with the Swiss air force (cerebral regulation to hypoxic conditions in Military pilot trainees), several professional sporting teams in cycling, rugby, tennis, football (ergogenic effects of high-intensity training in hypoxia) and with several Swiss hospital (therapeutic use of hypoxia in obese, hypertensive or arteriopathy patients)

In the first part of his life, he has been a professional triathlete (French Champion) and was coaching elite triathletes successively in the French, UK or Hong Kong teams. Grégoire attended several Olympic Games. He participated to ultra-endurance event in different sports (Vasaloppet; Embrun or Hawaii Ironman..). At the age of 50, he finished 2nd in the “Tor des Geants” in Italy.
