Dr Glenn McConell chats with Associate Professor Lykke Sylow from The University of Copenhagen. She is a rising star in exercise metabolism and in particular the effect of exercise on cancer. This is the second podcast episode on exercise and cancer (See Professor Kathryn Schmitz episode #9).
Remarkably she said that if you are a non-smoker your biggest risk of getting cancer is inactivity. Not clear if this is independent of obesity etc. Can associated with a reduction of insulin sensitivity and also cachexia (with the loss of muscle mass is very important). The cancer itself may cause insulin resistance. Exercise can reduce the likelihood of getting cancer, improve the prognosis during cancer treatment and reduce the likely of getting cancer again. There is even evidence that exercise can improve the effectiveness of chemotherapy and reduce the extent of metastasis. Really remarkable stuff. A lot more research is needed to clarify these things.

Dr Glenn McConell chats with Professor Paul D. Thompson who is Chief of Cardiology, Emeritus at Hartford Hospital, Hartford, CT and Professor of Medicine, Emeritus at the University of Connecticut. He has published over 500 peer reviewed journal articles, was a past President of the American College of sports medicine (ACSM) and was a impressively fast marathon runner. This is the third of a series of podcast episodes on sport cardiology (See Professor Benjamin Levine and Associate Professor Andre La Gercheâs episodes). We covered a lot of ground. There is a greater prevalence of atrial fibrillation in athletes (is it due to larger hearts?). We discussed possible reasons why coronary artery calcium/calcification is higher in athletes. He recommends 8000 steps done vigorously per day. Exercise is very important for your health. What exercise to do depends on your goals and health status. See time stamps further much more. We discuss his free substack called 500 rules of cardiology.

Dr Glenn McConell chats with Professor Bryan Heiderscheit from the University of Wisconsin in USA. He is an expert on running injuries. This is the third of a series of podcast episodes on running injuries (See Professor Irene Davisâs and Associate Professor Rasmus Ăstergaard Nielsenâs episodes). Bryan focuses on overstriding and how increasing the stride rate can reduce overstriding and therefore running injuries. The importance of making gradual changes in all aspects. Different kinds of running injuries when land on the forefoot vs the heel. He thinks the type of shoes (minimalist vs cushioned etc) doesnât make much difference to running injury rates etc. If bouncing up and down when running then may be overstriding which can result in injury. Some people bounce more but donât overstride, some people overstride but donât bounce and some do both. Bryan likes to try altering the stride rate/cadence to reduce over striding in an attempt to reduce bouncing and therefore, hopefully, running injuries. Bryan and the previous running. We also discussed causes of hamstring injuries during sprinting. A very interesting chat that brought together not only his research but also the previous two episodes on running injuries.

Dr Glenn McConell chats with Associate Professor Rasmus Ăstergaard Nielsen from Aarhus University who is an expert on the affect of training load and shoes on running-related injuries. This is the second of a series of podcast episodes on running injuries (See Prof Irene Davisâs episode).
Rasmus went from an overweight gamer to an injured runner to a exercise researcher! His research focuses on injury prevention, especially the importance of training load. Need to make slow changes. Seems donât need motion control shoes for those with âexcess pronationâ. His main point is that one needs to give the body enough time to adapt or the likelihood of injury is increased. So donât suddenly change things. This includes speed, distance, shoes, terrain etc. How gradual is gradual though? There tend to be different injuries from running long vs running fast (and when returning to running one should consider the cause of the original injury). What do in leisure time affects the total load. Shoes and running injuries. Very interesting stuff.

Dr Glenn McConell chats with Professor Irene Davis from the University of South Florida who is a top running injuries researcher and the current president of the American College of Sports Medicine. She makes the argument that we were born to run and have evolved to land on the ball of the foot during running and this reduces impact load compared with landing on the heel. Modern running shoes tend to increase the likelihood of landing on oneâs heel. She is a fan of minimalist shoes, which tend to result in landing on the forefoot not the heel. She also believes that neutral shoes are best rather than the commonly advised shoes that attempt to minimize pronation. In addition, she also believes that if one has stubborn injuries and have tried other rehabilitation retraining your running gait may be helpful. Not a huge fan of orthotics. I was actually blown away by the chat and very motivated by it. Really fun stuff. Twitter: @IreneSDavis0:00. Introduction to podcast/Irene Davis3:05. How Irene got into exercise research6:43.

Dr Glenn McConell chats with Professor Mark Haykowsky from the University of Alberta, Canada and remarkable heart transplant recipients Dwight Kroening, Edmonton, Alberta, Canada and Elmar Sprink, Cologne, Germany. Dwight was very fit before a heart defect resulted in his heart transplantation (HT) way back in 1986. Elmar was an endurance athlete who suffered a series of cardiac arrests before his HT 12 years ago. They have undertaken Ironman triathlons and more. Both had VO2 maxes in the high 50s! (ml/kg/min). They embody the importance of exercise. Really motivating stuff, incredible. I loved this chat with these three remarkable people. Twitter: @mhaykows0:00. Introduction5:40.

Dr Glenn McConell chats with Associate Professor Chris Fry from the University of Kentucky, USA. Joint injury causes muscle weakness and atrophy (reductions in muscle size) due to the the inactivity but also separately due to the injury itself. Substances are released from muscle to help repair the joint/bone. Prehab is important before surgery. There can be residual effects long after joint injury. We also discussed hypertrophy and aging and the importance of having a lot of muscle capillaries as age to obtain the optimum response to resistance training. Lots more. We had a really great chat.

Dr Glenn McConell chats with Assistant Professor Kevin Murach who is a rising star from the University of Arkansas, USA. Kevin is an expert on muscle, muscle growth, adaptation to exercise training, âmuscle memoryâ, the regulation of muscle growth and muscle memory and the effect of aging etc. Muscle memory definitely seems real (especially in slow muscle fibers). Looks like epigenetics involved more than changes to muscle fibers nuclei. But more work needs to be done, especially in humans. We had a really great chat. I enjoyed it a lot. A very smart chap.

Dr Glenn McConell chats with Dr Nicola Guess from Oxford University, England and Professor Jonathan Little from the University of British Columbia, Canada. Nicola is a dietitian researcher with many years of expertise including the importance or otherwise of glucose âspikesâ or excursions and the pros and cons of continuous glucose monitor use. Jonathan is an expert on exercise metabolism who is coming onto the podcast for the second time after speaking previously about keto diets and exercise. A major point is the difference between having chronically elevated blood glucose levels such as in diabetes (pathology) versus having normal increases in glucose ("spikes") in response to a meal. Also increases in glucose before and during very intense exercise is normal physiology and not a concern. There was also a clear message that the use of continuous glucose monitors (CGMs) have both pros and cons and that need to be considered. A very interesting chat. Twitter: @DrJonLittle

Dr Glenn McConell chats with Professor Luc van Loon from Maastricht University, The Netherlands. He is an expert with a wealth of knowledge on the role of physical activity/exercise and nutrition on muscle adaptation. A lot of his research focuses on protein and protein synthesis. He applies these studies to young healthy individuals, the aged and also has conducted important experiments on people in ICU. He makes it clear that most people, especially athletes, get enough protein in their diet so do not need to take supplements. Are there really non responders to exercise training? Anabolic resistance with aging is due to inactivity. Lots more. A very interesting chat.0:00. Introduction2:09. How Luc got into exercise research6:30. Moving into protein metabolism8:05.

Dr Glenn McConell chats with Professor Sue Bodine from the Oklahoma Medical Research
Foundation, Oklahoma, USA. She is an expert on muscle, in particular muscle atrophy with inactivity/aging. We chatted about how with age muscle size is reduced and this is associated with a reduction in muscle fiber size and also a loss of fast muscle fibers. Resistance training (and perhaps intense endurance exercise) can attenuate the rate of muscle atrophy. We discussed how much muscle atrophy is due to age per se and how much is due to inactivity. Anabolic resistance, protein synthesis, the importance of strength for balance etc. A very interesting chat.

Dr Glenn McConell chats with Assoc Prof Andre La Gerche a world leading Sports Cardiologist from St Vincentâs Institute of Medical Research, Melbourne, Australia. Acute exercise for long periods at a high intensity can result in abnormal right ventricle function. In addition, years of long, hard exercise training is associated with increased coronary artery calcium (CAC) levels and atrial fibrillation (AF). Despite this, Andre is a huge advocate of exercise across the population and generally even in these individuals.
