Lance Davidson

Biography

Lance E. Davidson, Ph.D., is an Assistant Professor in Exercise Sciences at Brigham Young University. He teaches classes in Exercise Physiology and Exercise Prescription. As an obesity researcher and exercise physiologist, his research interests include investigating the health benefits of obesity reduction, specifically the long term effects of bariatric surgery in severely obese individuals, and determining optimal exercise prescriptions for improving metabolic health and physical performance in aging and obese individuals. Dr. Davidson received bachelor and master degrees in physical education and exercise sciences from Brigham Young University in Provo, Utah. He obtained his doctorate in exercise physiology from Queen’s University in Ontario, Canada, where he conducted several randomized controlled exercise intervention trials assessing the effects of exercise on insulin resistance and physical function in middle-to-older aged individuals with diabetes and abdominal obesity. He received further training in NIH-funded post-doctoral fellowships at the New York Obesity Research Center, Columbia University, New York, and at the Division of Cardiovascular Genetics, University of Utah, where he was appointed as a Research Assistant Professor in Internal Medicine. He has been awarded several faculty development awards, including a Translational Comparative Effectiveness Research (TCER) Scholarship and a research career development (K12) award from the University of Utah’s NIH-funded Center for Clinical and Translational Science (CCTS), through which he earned an additional Master of Science degree in Clinical Investigations. His current research focus is on acute and long-term effects of bariatric surgery on body composition and metabolic health in severe obesity, including work on several large longitudinal cohort studies such as the Longitudinal Assessment of Bariatric Surgeries 2 (LABS-2) Trial and the Utah Obesity Study. He is the principal investigator on an NIH/NIDDK-funded grant (R21) investigating long-term bone fracture rates in gastric bypass surgery patients and severely obese controls in collaboration with investigators from the University of Utah, Intermountain Healthcare, and the Utah Population Database. He and his BYU students are also researching the efficacy of several resistance exercise modalities for improving muscle strength and function during rapid weight loss after bariatric surgery. Dr. Davidson is an active member of The Obesity Society.
