Ethan C. Hill, PhD, CSCS, EP, is an assistant professor in the School of Kinesiology and Rehabilitation Sciences at the University of Central Florida. He received his MS and PhD in exercise physiology from the University of Nebraska – Lincoln and BS in exercise and sport science from the University of Wisconsin – La Crosse. He is a member of the American College of Sports Medicine, the National Strength and Conditioning Association, and the American Physiological Society. The primary focus of Hill’s research is to identify the exercise modality that is most effective and efficient at stimulating muscle hypertrophy and increasing muscle strength in men and women. Hill examines eccentric contraction-based resistance training, low-load resistance training, blood flow restriction, and local vs. systemic hypoxia. His lab is currently applying their research to help mitigate age-related losses in muscle and endothelial function and to identify exercise countermeasures to offset the effects of zero gravity during prolonged spaceflight.
