#53 - Aging, exercise and muscle mitochondrial energetics with Dr Paul Coen
Inside Exercise
The Role of Nitric Oxide in Aging
Oral nitrate supplement elicits kind of high bioavailability and in the plasma. It's not just a beat it shots we've used those as well. The concentrated beetroot juice works really well too I mean that's a, that, that, you know, this it's a high level of nitrate nitrate.
Dr Glenn McConell chats with Dr Paul Cohen from Translational Research Institute for Metabolism and Diabetes, AdventHealth Orlando, Florida, USA. He has a very strong track record of research examining muscle mitochondria in health and disease and in particular the effects of exercise in attenuating the reductions in mitochondrial function with age.

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).
