Sebastian Weber is a sports scientist, coach of world class cyclists and endurance athletes, and consultant of multiple world class cycling teams and other endurance sports organisations and federations. He is also the co-founder of the physiological performance software INSCYD. In this two-part interview we discuss recent updates to the INSCYD platform and go deep into physiology and training concepts relevant for optimising endurance performance.    IN THIS EPISODE YOU'LL LEARN ABOUT: -INSCYD's Power Performance Decoder (PPD) - a tool that can take any combination of data (lactate, VO2, or power only) and calculate VO2max, VLaMax and anaerobic threshold with a high degree of accuracy -The accuracy of the PPD, and how it compares to traditional lactate or ventilatory testing -The mechanism of calculating VO2max and VLaMax using power data only -The original VLaMax testing protocol, and why it's near impossible to "DIY" it -Best practices for executing the testing protocol -FatMax: confusions around the metric and what it depends on -Benchmark values (and realistic expectations) for VO2max and VLaMax for males and females -How physiological testing on the bike relates (or doesn't) to running and swimming   SHOWNOTES: https://scientifictriathlon.com/tts237/   THAT TRIATHLON SHOW HOMEPAGE: www.thattriathlonshow.com   SPONSORS: Precision Hydration - One-size doesn't fit all when it comes to hydration.
