Exercise in the Brain Studies and the Importance of Blood Flow

Dr Glenn McConell chats with Associate Professor from the University of Wisconsin-Madison, USA. Jill is an expert on the brain and exercise. We discussed the effect of acute (one bout) and chronic physical activity/ exercise on cognitive function, brain blood flow (BBF), dementia/Alzheimer’s disease risk and progression etc. A very interesting chat.

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).
