#47 - Speed-duration relationship across the animal kingdom with Dr Mark Burnley

Dr Glenn McConell chats with Dr Mark Burnley from the Loughborough University in England. He is an expert on critical power (cycling) and critical speed (running). We compared and contrasted the speed duration relationship across the animal kingdom. Mark is an absolute wealth of knowledge on exercise intensity domains and critical power etc and comparative exercise physiology. Critical power is essentially one’s aerobic capacity and W’ is essentially one’s work capacity. Twitter: @DrMarkBurnley0:00. Introduction and how Mark’s entry into research6:12.

Outro (9 seconds)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).Connect with Inside Exercise and Glenn McConell at:Twitter: @Inside_exercise and @GlennMcConell1Instagram: insideexerciseFacebook: Glenn McConellLinkedIn: Glenn McConell https://www.linkedin.com/in/glenn-mcconell-83475460ResearchGate: Glenn McConellEmail: [email protected] to Inside exercise:Spotify: shorturl.at/tyGHLApple Podcasts: shorturl.at/oFQRUYouTube: https://www.youtube.com/@insideexerciseAnchor: https://anchor.fm/insideexerciseGoogle Podcasts: shorturl.at/bfhHIAnchor: https://anchor.fm/insideexercisePodcast Addict: https://podcastaddict.com/podcast/4025218Not medical advice
