303. The Weird Science of Carb Mouth Rinses, VO2 Max Limits, Fueling for Performance, Cross Training, and Cramp Prevention!

We put on our spacesuits for this great episode! The main topic was a study finding that just putting a dissolvable carb strip on the tongue could improve performance by 3% in a short time trial. What?! How can carb strips and mouth rinses improve performance? We discuss the weird implications of cephalic-phase responses. And this one was full of amazing topics! Other topics: our first movie theater trip in 3.5 years, a discussion of low energy availability and fueling for performance, Keely Hodgkinson discussing gaining power before her recent world championship win, why cross training is the hottest training topic, Courtney Dauwalter doing GOAT things, a strange study on hot underwater biking, plus a Q+A on VO2 max limitations, the many meanings of “talent,” preventing cramps, fueling and menstrual cycle disturbances, inflammation and adaptation, and a hypothetical coaching academy. May your saunas and tubs be even hotter than our astronaut costumes. We love you all!
