Sam Cheuvront, PhD & Robert Kenefick, PhD Rebroadcast part 1 of 2 - Sam Cheuvront, PhD & Robert Kenefick, PhD, two of the living legends of performance hydration, bring everything you could want to know about hydration for endurance athletes starting with the basics in this episode.
info_outline Herman Pontzer PhD - Burn 03/03/2021
Herman Pontzer PhD - Burn Major advances in our understanding of human metabolism have been made in recent years; they’ve been pioneered by Herman Pontzer, PhD. He, and his colleagues, are making discoveries in human metabolism and energy balance that will reshape our approach to human health for many years to come. These are fundamental breakthroughs issues relating energy intake, exercise, and body weight that have confused us for so long.
info_outline Keith Baar, PhD 02/18/2021
Keith Baar, PhD Dr. Baar rejoins us on the show. He was previously on for episode 58. Today we illuminate the central role of connective tissue and associated proteins in transmitting force from muscle, extend that understanding to explain how muscle functions in running (hint: it’s not at all like most people think), and dive into ways that you can optimize your connective tissue health.

Herman Pontzer, PhD Herman Pontzer, PhD is an evolutionary anthropologist at Duke University interested in how the human body evolved and how our species’ past has shaped our health and physiology today. He studies the ecology, lifestyle, diet and evolutionary history of humans and apes to better understand metabolism and health. As you’ll hear in the interview, we emphasize what hunter-gatherer societies can tell us about the human body because it’s the lifestyle of hunter-gatherers that created the bodies we have. Several years ago, Dr. Pontzer and his colleagues were curious about the total energy expended per day by people living as hunter-gatherers. They discovered that nobody had made the actual, direct measurements. It took them a while to convince funding agencies that this was a good use of research dollars because the reviewers thought ’these are very active people, they’re going to be expending a lot more energy than sedentary people, we have good estimates of that based on activity level, we’re not going to learn anything here’. But Dr. Pontzer and is colleagues persisted, got the funding, and did the direct measurements. They discovered that the Hadza people of Tanzania expend the same number of calories per day as sedentary people in the United States and other modern societies despite being much more active.

info_outline Iñigo Mujika, PhD On Strength 08/05/2020
Iñigo Mujika, PhD On Strength Iñigo is back on the show, following up on his recent appearance in episode 127. In the previous episode, we talked about tapering. In this episode, talk about strength training from every angle, and we dive into two specific examples of training tweaks that made big improvements for athletes he coaches.
info_outline Iñigo Mujika, PhD On Tapering 06/25/2020
Iñigo Mujika, PhD On Tapering Iñigo Mujika (PhD) has coached numerous Olympians, national teams, and is recognized as one of the top triathlon (swimming, cycling, and running) coaches in the world. He's published over 100 peer-reviewed articles, books, and book chapters. He literally wrote the book on tapering, which is the main focus of our discussion though we touch on many other important and practical topics. Find all the links we talk about at https://scienceofultra.com/podcasts/127
info_outline David Bishop, PhD 06/11/2020
David Bishop, PhD David Bishop, PhD is a Professor at Victoria University in Australia and an expert on the health and performance outcomes of exercise prescription with a particular emphasis on mitochondrial adaptations. Recently, he’s been studying the impact of twice-per-day training. You’ll learn, for example, that running twice in a day may be more beneficial than training for the same duration in one long run. And, we explore many other topics that will help you take your workouts to the next level.
info_outline Jose Areta, PhD 05/28/2020
Jose Areta, PhD Jose Areta studies energy availability, training, and performance. We talk about his recent case study of an amenorrhoeic athlete who restored their menstrual cycle while training and competing at a high level, his comprehensive review of glycogen utilization, and how an athlete can loose weight while training for performance and periodizing carbohydrate intake.
info_outline Mark Burnley, PhD 05/14/2020
Mark Burnley, PhD My guest today is Mark Burnley, PhD from the University of Kent. He's studies endurance physiology, especially the power-duration relationship. For example, he was part of the group that first validated the 3-minute all-out test to estimate critical power. He's spent much of his career questioning why we can only maintain exercise when the intensity is less than 20-30% of our ability to generate force…why do we have so much additional capacity when we can't sustain it?
info_outline Patrick Wilson, PhD 04/30/2020
Patrick Wilson, PhD Patrick Wilson (PhD) is an Associate Professor at Old Dominion University and author of a newly published book, The Athlete's Gut. He was a guest in episode 16. Today, we update our understanding of gut physiology from when he was first on the show but spend most of our time on lots of new and applied questions relevant to your training, racing, and adventures.
info_outline Andy Jones, PhD 04/16/2020
Andy Jones, PhD Andy Jones is one of the world's leading experts in human performance physiology, especially in the realm of endurance. Nike recognized this when they brought him onto the Breaking 2 project. He's most famous in many circles for his pioneering work using nitrates to boost performance. Yes, this is the beetroot guy. Today we talk about mechanisms of fatigue, critical speed/power, evidence-based approaches to training, and (of course) beetroot juice.
