322. Why Exercise Physiology Wisdom Can Be Wrong, Doping in Ultrarunning, Bicarb in Long Races, and AI Controversy!

We excavated sand from sensitive places before this great episode! A main topic was a new study on cold water immersion, with surprising results that contrasted with the hypothesis of researchers and upended the conventional exercise physiology wisdom. We talked about why that offset might be important for how we think about big training and physiology questions. The word of the day is “nuance.” Also “Andromeda.” We also did a Controversial Topics Corner! The 3 topics were recent discussions on doping in ultrarunning, the Hank Green AI conversation, and speculation about illegal “fairings” being used in the Tour de France Femmes. Our opinions may not be right. But in our defense, at least we’re not making front-facing social media videos about them. And this one was full of cool topics! Other topics: Megan’s learning experience, a study on bicarb in longer events, 2 cool studies on low energy availability and variable carb intake, and questions on returning to running, hot yoga, nasal hair, strength, immortality, ferritin, and more. May your bras be long, strong, and down to get the lack of friction on due to their aerodynamic construction. We love you all! Huzzah!
