Dr. Ivy’s research has pioneered our understanding of muscle metabolism and the role that properly formulated nutritional supplementation can play in improving exercise performance, recovery and training adaptation. His current research is centered around understanding the interactions of exogenous dietary nitrite/nitrate (NOx) on the endogenous NO/cGMP pathway and how dysfunctions in each system can affect cardiovascular health.

Dr. Ivy received his Ph.D. in Exercise Physiology from the University of Maryland, and trained in physiology and metabolism at Washington University School of Medicine as an NIH Post-Doctoral Fellow. He has served on the faculty at the University of Texas for over 30 years and as Chair of the Department of Kinesiology and Health Education for about half that time.
