Description

Dr Glenn McConell chats with Professor Jørgen Jensen from the Norwegian School of Sport Sciences about Carbohydrate and protein requirements of endurance athletes. He has over 30 years of experience examining these areas. We focussed on muscle glycogen depletion during exercise and glycogen resynthesis after exercise. He thinks no mechanistic link between glycogen content and fatigue. Also discussed combined carbohydrate and protein ingestion and protein requirements for endurance athletes. A short discussion on his work with caffeine and exercise and his current research.

Inside Exercise brings to you the who's who of 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).
