Dr. Jeff Zachwieja is a Research Fellow at the Gatorade Sports Science Institute (GSSI) in Barrington, Illinois. His areas of interest include sports nutrition with an emphasis on the physiological effects of carbohydrate and protein ingestion before, during, and after exercise. Dr. Zachwieja has specific research expertise in the use of stable isotopes to study whole body protein turnover, as well skeletal muscle protein synthesis rates. He has used exercise, bed rest, and hormones as a model to understand the regulation of human skeletal muscle protein turnover. Dr. Zachwieja earned his bachelor’s degree from the University of Illinois and master’s degree from Eastern Illinois University, both in Physical Education. In 1991 he received a doctorate in human bioenergetics from Ball State University where he worked with Dr. David Costill, recognized world wide as an authority in sport and exercise science. From 1991–1994 he completed a postdoctoral fellowship in the Division of Diabetes, Endocrinology and Metabolism at the Washington University School of Medicine in St. Louis, Missouri. He then served as assistant professor and chief of the Exercise and Nutrition Program at the Pennington Biomedical Research Center in Baton Rouge, Louisiana, until August of 2000 when he joined GSSI. Dr. Zachwieja is an author or co-author on more than 40 publications, many appearing in the most respected scientific journals in the field. He has given numerous invited presentations in the U.S. and abroad and is a fellow of the American College of Sports Medicine.
