In this show, we explore the cardinal directions of training, nutrition, recovery, and mindset, delving into the dynamic relationship that drives athletic success. Athletes are more than numbers; they're individuals with unique lifestyles and mindset challenges. Coaches who understand these personal nuances play a vital role in their athletes' journey. While training details and data are important, tools like Athletica provide a solution to streamline the technicalities, allowing coaches to focus on the human connection which makes the human coaches the best they can be. Each week, renowned sports scientist and researcher Paul Laursen will be our teacher and guide as we break down training principles so you can understand how best to train for your sport! We take a no-bullshit and practical approach to support age-groupers, masters, and everyday cyclists, runners, and triathletes like you as you find your direction as an athlete. The hosts are Paul Laursen, sports scientist and founder of the Athletica.ai training platform, Marjana Rakai, coach, sports scientist, and triathlete, and Paul Wa…","last_synced_at":"2026-07-24T08:21:02.703077+00:00","page_url":"https://stenobird.com/podcast/the-athlete-s-compass-6705232"},"episode":{"title":"The Second Threshold Explained: LT2, FTP & Critical Power Demystified","slug":"the-second-threshold-explained-lt2-ftp-critical-power-demystified","published_at":"2026-02-12T19:00:00+00:00","page_url":"https://stenobird.com/podcast/the-athlete-s-compass-6705232/the-second-threshold-explained-lt2-ftp-critical-power-demystified","show_page_url":"https://stenobird.com/podcast/the-athlete-s-compass-6705232","url":"https://athletica.ai/the-athletes-compass-podcast/the-second-threshold-explained-lt2-ftp-critical-power-demystified","audio_url":"https://episodes.captivate.fm/episode/0a5d9428-289c-4942-984f-542085ffed03.mp3","summary":"In this episode of The Athletes Compass , Dr. Paul Laursen and the team break down the science and practical application of the second threshold — also known as LT2, VT2, FTP, or critical power. They explain what physiologically happens when you cross this boundary, why base training is essential before adding threshold work, and how over-unders, tempo sessions, and VO2 max intervals raise performance. The conversation explores common mistakes athletes make (especially doing too much intensity), the role of durability, and how to assess threshold progress without lab testing. If you want to train smarter, improve pacing, and sustainably increase performance, this episode delivers a masterclass in intensity control. Key Takeaways LT1 vs LT2: LT1 (aerobic threshold) = top of Zone 2, sustainable “all-day” effort. LT2 (second threshold) = highest sustainable steady-state effort before rapid fatigue. Above LT2: Glycolytic demand increases, lactate accumulates faster, heart rate drifts, and fatigue accelerates. Functional vs Lab Testing: FTP and critical power are practical field markers of LT2. Lab tests measure physiology, but field tests often matter more for performance. Day-to-Day Variation Is Real: Sleep, fueling, equipment, environment, and training phase can significantly affect test results. Base Training First: A strong aerobic base (mitochondrial development) improves tolerance to threshold work and increases fat oxidation capacity. Over-Unders Work Because: They stimulate mitochondrial adaptations by forcing lactate clearance and improving aerobic durability. Intensity Control Matters: Spending more time in the correct zone is more beneficial than constantly pushing the top end. Most Common Mistake: Too much high-intensity work without sufficient aerobic base.
