Some Work, All Play

David Roche and Megan Roche

Details

Five to ten topics, sometimes about running, with lots of love and enthusiasm and science. We dig deep into training, races, studies, pop culture, and much more! With Megan Roche, M.D. and David Roche!

334. Running Form and Fatigue Resistance, Bombshell Doping News, Lactate Gel Experimenting, and How Sweat Rate Changes Over Time!
We got in trouble at the gym before this great episode! The main topic was a new study tying deteriorating fatigue resistance to increased duty factor (ground contact time). Essentially, the longer the foot stays on the ground after a couple hours of work, the worse the fatigue resistance. That points toward neuromuscular interventions that could improve endurance. And this one was full of awesome topics! Other topics: lactate gel experimentation, the major doping bust in road marathoning, menthol gels, our issues with high-carb drink mixes in ultras, how sweat rate varies across an event, a study on deception methods improving performance, steady running the day after long runs, shaving your legs, Strava etiquette, the problems with MAF training, and a big discussion of why we look to training approaches that work for pro female athletes to derive some training theory. Welcome to the best episode! Oh, actually that’s supposed to say “vest” episode. We regret the error. We love you all! HUZZAH!

330. Carbs Before Short Efforts, Why Bicarb May Cause Long-Term Adaptations, The Brain-Body Connection, and Strength Work Before Races!
We had some deep thoughts on cheese before this great episode! The main topic was a new study on sodium bicarbonate, showing performance benefits in a long, intense protocol. We zoom out to talk about potential connections to mitochondria... in rats (sometimes). Our theory: bicarb is driving some of the performance changes we are seeing via long-term adaptation processes within cells. And this one was full of awesome topics! Other topics: Megan’s deep thoughts on the uphill treadmill, the Toe Pro, bicarb pills, the new gear-shifting shoe from Adidas, a study on the brain-strength connection via “mental contraction training,” how hot water immersion and training interact, when to stop strength work before races, what Matt Carpenter would do in the modern era, whether big prize purses will cause more doping in trail running, carb needs before 5k races, fatigue resistance from life, bicarb lotions, and process v. results mindsets in racing. The big PSA from this episode: be careful with your search history. Also, feel free to use our example for a convenient excuse. It will make more sense soon. We love you all!
