#66 - Exercise and the cardiovascular system with Professor Ylva Hellsten

Dr Glenn McConell chats with Professor Ylva Hellsten from the University of Copenhagen in Denmark. She is an authority on the effect of exercise on blood flow and cardiovascular function. We talked about heart rate before exercise and blood flow and blood pressure during and after exercise. She pointed out that muscle blood flow can increase by 100-fold during exercise! We discussed the effect of physical activity and aging/inactivity and menopause on the cardiovascular system. Also the protective effects of exercise training and the importance of doing the physical activity that you enjoy. A very interesting chat. Twitter: @CVgroupNEXS. 0:00.

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
