Background

Nancy Rehrer is a Senior Lecturer in the School of Physical Education with a joint appointment in the Department of Human Nutrition. 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 an active member of Sports Medicine Australia as well as Sports Science & Exercise Science New Zealand (SESNZ) and holds SESNZ practitioner accreditation in Exercise Physiology and Sports Nutrition. She has spent research leave time (2001) with colleagues at the Laboratory for Human Environmental Physiology at the Ames Research Ctr. /NASA. She is on the editorial board of The International Journal of Sports Medicine and Medicina Sportiva 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. Ex. Metab., etc.)

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 work with 13C isotopically labelled glucose and doubly labelled water to assess substrate and energy metabolism during exercise; research on regulation of sodium and fluid balance during exercise; dietary needs during (ultra-) endurance exercise; and performance determinants in downhill mountain biking. She is also involved in interdisciplinary research on environmental influences on physical activity and well-being.
