Clinical Interests

Dr. Marty Hoffman has been fortunate to blend some of his professional activities with his personal pursuits involving endurance exercise and wilderness adventures. His research has focused on applied exercise physiology, human locomotion, pain perception and human performance, while his clinical work has involved cardiac rehabilitation, musculoskeletal medicine and sports medicine. He has been a competitive cross-country skier or distance runner for most of the last 40 years, with one of his recent accomplishments being the Grand Master (50-59 age group) National Champion of the 2008 USA Track and Field 100 Mile Trail Running Championship. He became a Fellow of the American College of Sports Medicine in 1989, has served as Director of Research for the Western States Endurance Run since 2006, and previously worked with the US Biathlon Team as a team physician and scientist. He serves on the editorial boards of the Archives of Physical Medicine and Rehabilitation, Science and Sport, and Research in Sports Medicine. He is also active in wilderness medicine as a certified Wilderness First Responder, works with his local Search and Rescue program, and has become a regular speaker at wilderness medical meetings.
