Dr Glenn McConell chats with Professor José Calbet from the University of Las Palmas de Gran, Canary Islands, Spain. José has a very strong research record and is a global leader in his field. He has done amazing invasive exercise studies in humans to determine the limiting factor(s) to VO2 max. We talked about what is VO2 max, the factors determining VO2 max, the limits to VO2 max, the effects of VO2 max on exercise performance, pseudoanemia, VO2 max in females, VO2 max in masters athletes etc. In general he is finding the oxygen delivery is the main limiting factor to VO2 max. A very interesting, long chat. Twitter: @GRHEFS_ULPGC 0:00. Introduction and how José got into exercise research

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).
