Inside Exercise

Dr Kevin Murach, an expert on muscle growth and adaptation to exercise training, discusses the concept of muscle memory and its relationship with epigenetics. The podcast explores studies on mice models, exploring endurance and strength effects, as well as the mechanisms of muscle memory such as epigenetics and microRNA. The importance of nuclei in muscle fibers for muscle growth and adaptation is also discussed.

Dr. Nicola Guess and Professor Jonathan Little discuss the importance of managing glucose 'spikes' after a meal or intense exercise. They explore the difference between glucose spikes and chronic hyperglycemia in diabetes, the relationship between carbohydrate intake and blood sugar control, the pros and cons of continuous glucose monitoring, understanding pre-diabetes glucose levels, and the role of beta cells in type 2 diabetes and exercise.

Dr Jill Barnes, an expert on the brain and exercise from the University of Wisconsin-Madison, discusses the effect of exercise on cognitive function, brain blood flow, dementia risk, and progression. Topics include measuring brain blood flow, regional blood flow in the brain, the relationship between exercise intensity and brain health, resistance training and cognitive function, the impact of exercise on brain endothelial function, and exercise's influence on the risk of stroke and dementia.

Professor Margie Davenport, an expert on exercise and pregnancy, discusses the beneficial effects of exercise before and during pregnancy on both the mother and the fetus/offspring. Topics include exercise intensity during pregnancy, fetal heart rate during exercise, contraindications, effects on placenta blood flow and the fetus, reduced pre-eclampsia, exercise during pregnancy for elite athletes, and exercise timing and recommendations. The importance of research, debunking myths, and consulting healthcare providers is emphasized.

Professor Darren Candow, an expert on creatine and its effects on exercise and health, discusses various topics including strength gains from creatine supplementation, effects on muscle and brain creatine levels, benefits for vegetarians/vegans, aging and creatine, mechanisms of action, optimal dosage, creatine transporters, side effects, sarcopenia, effects on muscle and bone, and the interaction between caffeine and creatine.

Dr Nisha Charkoudian, expert on effects of extreme environments on exercise capacity, discusses dehydration, effects of humid vs dry environments, importance of including both sexes in studies, and thermoregulation and blood pressure with aging. Very interesting chat.

Dr Morten Hostrup, an expert on beta2-agonists, discusses asthma in athletes, negative effects on VO2 max, different types of beta2-agonists, legal limits of use, and the acute and chronic effects on muscle mass, sprinting, strength, and endurance.

Dr. Glenn McConell chats with Professor Luc van Loon, an expert in exercise and nutrition. They discuss protein needs, the effects of exercise on protein synthesis, and debunk the need for supplements. They also explore the individual variation in exercise response and the role of physical activity in restoring antibiotic response. The podcast covers muscle adaptations in ICU patients, resistance training for the elderly, collagen supplementation, and the importance of diet and exercise for overall health.

Professor Michael Kjær, an expert on tendons and exercise, discusses various topics including tendon injuries, prevention and treatment, muscle-tendon interactions, factors that determine injury vulnerability, autophagy and mitophagy in maintaining muscle and tendon health, tendonopathy and potential treatments, shockwave therapy for calcifications, collagen supplementation, secretion of molecules by tendons during exercise, influence of circadian rhythm and sleep on tendons.

Dr. Glenn McConell chats with Professor Sue Bodine, an expert on muscle atrophy with inactivity/aging. They discuss muscle size reduction and loss of fast fibers with age, how resistance training can slow muscle atrophy, anabolic resistance, the role of hormones and protein synthesis in muscle aging, the amount of exercise needed to attenuate muscle atrophy, the importance of exercise after bed rest, and the impact of intense endurance exercise on muscle fiber size.
