Nancy Rehrer is an Associate Professor in the School of Physical Education, Sport & Exercise Sciences. She studied Environmental Biology at Duke University as an undergraduate and then completed a Master's in Nutrition at Clemson University and a PhD in Exercise Metabolism/ Nutritional Physiology at Maastricht University.

Dr Rehrer won The Dutch Prize for Sports Medicine in 1991 for her PhD thesis 'Limits to Fluid Availability During Exercise'. She is a Fellow of the American College of Sports Medicine. Dr Rehrer is also a member of The Nutrition Society (British). She has spent research leave time (2001) with colleagues at the Laboratory for Human Environmental Physiology at the Ames Research Ctr./NASA and at The Centre for Nutrition Research in Lyon (2013).  She is on the editorial board of The International Journal of Sports Medicine and the Journal of Sports Medicine  and is a reviewer for most of the major journals in Exercise Physiology and Sports Nutrition (eg. J. Appl. Physiol, Med. Sci. Sports Exerc., Int. J. Sports Nutr. Exerc. Metab., etc.). She also has been an invited member of the expert panel to develop the consensus statement on exercise associated hyponatraemia 2008 and 2015.

Research Interests

Dr. Rehrer's major interests include how metabolism is altered via exercise and mechanisms that limit human performance. Some of the research is sport performance based and some is related to health and general knowledge of human function in relation to the environment. Specific areas of recognised expertise include fluid & electrolyte balance during exercise, substrate metabolism during exercise and gastrointestinal function during exercise.

Recent projects, and those of her post-graduate students, include: evaluating the effect that activities of daily life have on health parameters; using 13C isotopically labelled glucose and doubly labelled water to assess substrate and energy metabolism during exercise; evaluating effects of (chronic) sodium intake on acute fluid and sodium balance during exercise; effects of environmental temperature on   metabolic rate and sympathetic/ parasympathetic drive.
