Dr Glenn McConell chats with Professor Karyn Esser from the University of Florida, USA. She is an authority on circadian biology. We discuss whether exercise affects muscle circadian clocks and whether muscle clocks affect exercise. What is the best time to exercise and to eat etc. Also the effects of jet lag and shift work and how to best manage these. A very interesting chat. Karyn’s Twitter: @kaesser.

Inside Exercise brings to you the who's who of research in exercise metabolism, exercise physiology and exercise’s effects on health. With scientific rigor, these researchers discuss popular exercise topics while providing practical strategies for all.
The interviewer, Emeritus Professor Glenn McConell, has an international research profile following 30 years of Exercise Metabolism research experience while at The University of Melbourne, Ball State University, Monash University, the University of Copenhagen and Victoria University.
He has published over 120 peer reviewed journal articles and recently edited an Exercise Metabolism eBook written by world experts on 17 different topics (https://link.springer.com/book/10.1007/978-3-030-94305-9).
