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.

S2 EPISODE 5 - Hydration & Heat Acclimatization in Athletes w/ Dr. Stavros Kavouras PhD

In Season 2 Episode 5, Dr. Bubbs sits down with world expert hydration researcher Dr. Stavros Kavouras PhD who runs the Hydration Science Lab at the University of Arkansas. In this episode, Stavros discusses how dehydration can impact athletic performance, differences between endurance and strength or team-sport athletes, the impacts of water loss on athletes trying to make weight, strategies for assessing for dehydration, if drink to thirst is sufficient for elite athletes, performing in hot climates and acclimatizing to warmer environments. Fantastic insights from one of the world’s best!

Lay-Ups

  1. Even a 2% reduction in hydration can lead to performance declines in athletes.
  2. Drink to thirst is an effective strategy in recreational athletes, but not performance driven people.
  3. Inability to heat-acclimatize is a major roadblock to performance.
