Dr Glenn McConell chats with Professor Scott Trappe, Director of the Human performance laboratory at Ball State University, Indiana, USA. We spoke about the influence that Scott’s supervisor, the great David “Doc” Costill, has had on exercise physiology (long time Ball State HPL Director before Scott). We then discussed the negative effects of space on the human body and whether exercise can minimize these negative effects. In space slow muscle fibers atrophy more than fast fibers and there is a large shift to fast fiber types. Exercise attenuates this. A very interesting, relaxed, fun chat. @HPLBallState 0:00.

1:41:30. Outro (9 secs) 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).
