Dr Glenn McConell chats with Professor Mark Tarnopolsky from McMaster University in Canada. Mark has done pioneering studies in many areas including sex differences and exercise, HITT training and creatine supplementation. Today we focus on his remarkable work with muscle myopathies. Exercise can be beneficial in all muscle myopathies in regards to function and/or healthspan and/or lifespan. The type of exercise will differ depending on the myopathy: endurance, resistance, or both.0:00. Introduction and overview of Mark’s exercise, clinical and research4:45.

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: glenn.mcconell@gmail.comSubscribe 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.Disclosure: Prof Tarnopolsky is the Founder and CEO of the Exerkine Company.
