Dr Glenn McConell chats with Professor David Wright from the University of British Columbia, Canada. He has undertaken a lot of important work on the effect of exercise on muscle glucose uptake and mitochondria and then has branched out to examine the effect of exercise training on mitochondria in adipose tissue (fat). We discussed his work around that and then talked about an interesting new focus of his work around the metabolic effects of antipsychotics. He is finding that exercise can prevent the acute blood glucose raising effects of antipsychotics. A very interesting chat.

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).
