Zachary Callahan, assistant professor of exercise physiology, joined the Ohio Northern University family in 2015. Previously, he taught exercise physiology classes at Western Kentucky University (WKU) in Bowling Green, Ky., and anatomy and physiology courses in the biology department at Miami University in Oxford, Ohio.
After spending some time outside academia, Callahan received his undergraduate and master’s degrees in exercise science from WKU. His master’s thesis investigated the effect that varying cadence had on sub-maximal VO2 estimations of VO2 max. Basically, he was interested in seeing if the standard test (exercise bike) used to estimate a person’s maximal oxygen capacity could be improved by having the subject pedal at different RPMs.
Callahan taught for two years at WKU before moving to Oxford to work on his Ph.D. at Miami University. At Miami, Callahan completed his doctoral thesis while investigating the effect that inactivity and high-fat diet had on the development of diabetes.
At ONU, Callahan teaches Introduction to Exercise and Health, Sport Nutrition, Advanced Exercise Testing and Assessment, Motor Learning, Kinesiology, and Anatomical Structure and Function.
