S2 EPISODE 44 - Athletes, Exercise Immunology & Immuno-Nutrition w/ Dr. David Pyne PhD

Season 2 Episode 44, Dr. Bubbs interviews expert physiologist Dr. David Pyne PhD to talk exercise immunology and keeping athletes cold and flu free. In this episode, Dr. Pyne reviews the fundamentals of immunology and how the immune system is regulated by exercise and nutrition. He’ll discuss how training volume, intensity and load impact immunity, and more importantly, why keeping athletes cold and flu free is paramount for athletic success. Dr. Pyne also discusses the key immunity biomarkers and how effective they may (or may not) be at flagging at-risk athletes. Finally, he dives into the topic of immune-nutrition and how the food you eat, and supplements like probiotics, can impact athlete immunity and therefore ability to train and compete.

S2 EPISODE 34 - Nutritional Strategies for Elite Bodybuilders & Building Muscle w/ Dr. Andrew Chappell PhD

Season 2 Episode 34, Dr. Bubbs interviews nutrition expert and 5x British Bodybuilding champion Dr. Andrew Chappell PhD to discuss his research in elite male and female bodybuilders. In this episode, Andrew will discuss the overall energy intake and macro breakdown of elite bodybuilders: how much protein they consume, key differences in carb consumptions between bodybuilders who place in the top-5 versus the rest of the pack, and how fat intake differs between USA and British bodybuilders. Andrew also talks about the massive variance in caffeine intake, key factors like meal frequency and number of different food items consumed, and the most common supplementation practices amongst the best of the best. Andrew also shares his own insights from years of competing at the highest level.
