Research Journey and Interest in Exercise Physiology

Dr Glenn McConell chats with Dr Carlos Henríquez-Olguín from The University of Copenhagen, Denmark. Carlos is an up and coming rising star exercise metabolism researcher. He discusses the challenges of doing mechanistic exercise research in Chile and how he ended up moving to the University of Copenhagen. Language challenges etc. He has been doing really ground breaking research on reactive oxygen species (ROS) and contraction/exercise and already won awards for his research. Twitter: @MuscleBiology.

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).
