Dr Glenn McConell chats with Professor Paul D. Thompson who is Chief of Cardiology, Emeritus at Hartford Hospital, Hartford, CT and Professor of Medicine, Emeritus at the University of Connecticut. He has published over 500 peer reviewed journal articles, was a past President of the American College of sports medicine (ACSM) and was a impressively fast marathon runner. This is the third of a series of podcast episodes on sport cardiology (See Professor Benjamin Levine and Associate Professor Andre La Gerche’s episodes). We covered a lot of ground. There is a greater prevalence of atrial fibrillation in athletes (is it due to larger hearts?). We discussed possible reasons why coronary artery calcium/calcification is higher in athletes. He recommends 8000 steps done vigorously per day. Exercise is very important for your health. What exercise to do depends on your goals and health status. See time stamps further much more.

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-mcc
