Dr Glenn McConell chats with Assistant Professor Kevin Murach who is a rising star from the University of Arkansas, USA. Kevin is an expert on muscle, muscle growth, adaptation to exercise training, “muscle memory”, the regulation of muscle growth and muscle memory and the effect of aging etc. Muscle memory definitely seems real (especially in slow muscle fibers). Looks like epigenetics involved more than changes to muscle fibers nuclei. But more work needs to be done, especially in humans. We had a really great chat. I enjoyed it a lot. A very smart chap.

Outro 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
