Peter Leo is an applied exercise physiologist and high performance coach from Austria. Peter has done extensive research in profiling performance and physiological characteristics of U23 cyclists which we discuss in this interview. We also discuss power profiling and using Critical Power.   IN THIS EPISODE YOU'LL LEARN ABOUT: -Best practices for power profiling (e.g. formal testing vs. raw training data) and methodological considerations -What is Critical Power, and why use that as a main physiological marker over others (such as MLSS and FTP) -Power changes in U23 cyclists across a season -How training characteristics (e.g. training intensity distribution as well as added load from racing) impacted the change in power profile across the season -Practical takeaways from these studies - what can we learn when thinking about how we go about our own training and racing across an entire season?     SHOWNOTES: https://scientifictriathlon.com/tts319/   SCIENTIFIC TRIATHLON AND THAT TRIATHLON SHOW WEBPAGE: www.scientifictriathlon.com/podcast/   SPONSORS: ROKA - Exceptional quality triathlon wetsuits, trisuits, swimskins, goggles, performance sunglasses as well as prescription eyeglasses and sunglasses.  Online vision test for prescription updates and home try-on options available for eyeglasses.
