Inside Exercise

Dr Glenn McConell chats for a second time with Professor Michael Joyner from the Mayo Clinic, Minnesota, USA. Michael blew me away with his absolutely amazing knowledge on past athletes and coaches and their endurance training methods. Very different types of training can result in similar results. His running Haiku: Run a lot of miles, some faster than your race pace, rest once in a while. Michael was first on the podcast on October 9th, 2022. Michael’s Twitter: @DrMJoyner

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).

Dr Glenn McConell chats with Professor Jonathan Little from University of British Columbia. Kelowna, Canada. He is an expert on metabolism, nutrition, type two diabetes and exercise. We discussed what are keto (ketogenic) diets, different types of keto diets, the rationale for them and their effect on heath and exercise performance. We then did the same with ketone supplements. Whether there is a rationale for keto diets depends on who you are (overweight vs lean, insulin sensitive vs T2D, athletes vs non athlete etc).

Dr Glenn McConell chats with Professor Margo Mountjoy from McMaster University in Canada. A wide ranging and at times emotional discussion about the types of harassment and abuse (psychological abuse underlies most), prevalence of abuse (higher in marginalized groups), power relationships, reporting policies and procedures, barriers to reporting abusive behavior, the Nasser case, how empower the good people to effect change etc. Trauma informed care, the 4Rs: Realising that trauma is common, recognizing the signs of trauma in other people, responding to it and resisting retraumatization. A very passionate, compassionate and caring person.

Dr Glenn McConell chats with Professor José González-Alonso from Brunel Univesity London. We discussed exercise in the heat, dehydration, fluid ingestion, blood flow, metabolism and human circulation. He has a very strong research track record having researched these areas for around 35 years. We discuss how he began his career doing research with some very big names.

8:20. Exercise in mild environmental conditions 

11:20. Loss of bodily fluids during exercise 

14:13. Heart rate and the periphery 

16:35. Why cardiovascular drift during prolonged exercise? 

19:23. Effect of dehydration on ex performance 

23:50. Effects of fluid ingestion during exercise

Dr Glenn McConell chats with Professor Kirsty Elliott-Sale from Manchester Metropolitan University, England. She is an expert on female exercise physiology . We discuss the effects of the menstrual cycle, oral contraception, pregnancy and the menopause on exercise performance. As will become apparent, more research needs to be done on these important areas.

Dr Glenn McConell chats with Professor Stuart Phillips from McMaster University in Canada. He is the world expert on protein needs for optimal muscle mass with exercise. We discussed gaining muscle to combat losing muscle. The discussion centered around resistance training, dietary protein needs, whether need protein from meat, the timing of protein intake, the need for protein supplements and protein needs with aging. Lots more. He has been very open to changing his views based on the data. An important, fun chat.

Dr Glenn McConell chats with Professor Graham Holloway from the University of Guelph in Canada. He is an expert on mitochondrial bioenergetics. We discussed the effect of exercise intensity and duration and exercise training on fat/lipid and carbohydrate metabolism, whether alterations in substrate availability such as high fat diets, high fat meals, high carbohydrate meals etc affect fat oxidation and mitochondrial function and the effect of high fat diets on insulin sensitivity. Central role of ADP.

Dr Glenn McConell chats with Professor Mark Hargreaves from the University of Melbourne in Australia. He is a leader in exercise metabolism/physiology and was Glenn’s PhD supervisor. The discussion centred around the effects of muscle glycogen availability and carbohydrate (CHO) ingestion on exercise metabolism and also performance/fatigue. There was also discussion of  high fat/ketogenic diets, GLUT-4, the central nervous system and the effect of the volume of fluid ingested with and without addition of electrolytes.
