概要

 In this episode, Rob and Stephan explore the psychological risks of self-quantification, the science of aerobic capacity, and the physiological nuances of lactate thresholds.📝SummaryBiological data scientists Rob and Stephan discuss the "dark side" of the quantified self, specifically focusing on orthosomnia, a condition where sleep tracking leads to increased anxiety and worsened sleep quality. They reflect on the importance of using technology as a tool for a specific purpose rather than making the tracking itself the goal. The conversation transitions into a deep dive on VO2 max, explaining its critical role as a longevity predictor and the varying results obtained from different exercise modalities like cycling and running. Finally, the hosts break down the science of lactate thresholds, explaining how the body's metabolic shift from aerobic to anaerobic states serves as a vital biomarker for training optimization.⏳Chapters00:00:00 Introduction: The dark side of tracking and VO2 max00:00:55 Orthosomnia: When sleep tracking causes insomnia00:05:09 The psychological impact of metrics and obsession00:13:13 Tracking with purpose: Avoiding the identity trap00:25:59 Oura Ring experiences: “Injuries” and data accuracy00:30:50 Strength training and basal metabolic rate00:36:47 VO2 Max: The ultimate longevity marker?00:38:26 Hazard Ratios: Comparing fitness to smoking00:44:39 The U-shaped curve of exercise volume00:49:37 Gold Standard: VO2 max lab testing protocols01:04:25 Training for capacity: The Norwegian 4x4 protocol01:07:51 Lactate thresholds and metabolic switching01:16:09 Wearable estimations: Garmin vs. Apple vs. Oura01:21:47 VO2 Max Records: Oskar Svendsen (97.5) and Tadej Pogačar (96)01:23:42 Teaser: Biological age and integrative biomarkers📚ResourcesOrthosomniaThe Molecular Precision Medicine Master’s Programme at Medical University of Vienna (where Rob and Stephan teach)Quote for purposeful tracking: "I shall not waste my days in trying to prolong them" - Jack LondonNatural language processing (NLP)Semantic analysisDevelopment of a scale for measuring orthosomnia: the Bergen Orthosomnia Scale (BOS)Sleep tracker use nears 50%, AASM survey findsPrevalence of Orthosomnia in a General Population Sample Dark triad (Personality Traits)Basal metabolic rate (BMR)BMR Calculator Lean body mass was found to be the single predictor of BMRPhelps supposedly consumed 8,000-10,000 kcal per training day before the Olympic GamesVO2 maxHazard ratioHow does VO2 max correlate with longevity? - Peter Attia Physical activity types, variety, and mortality: results from two prospective cohort studies Peak oxygen uptake was strongly correlated to total heart volumeRob's VO2 max results: 58 for cycling, 54 for runningStephan's VO2 max results: 42 for cycling, 49 for runningVO2 max percentile calculatorVO2 Max ChartAerobic high-intensity intervals improve VO2max more than moderate training (Norwegian 4x4) How to Improve Your Cardio Capacity (VO2 Max)Lactate threshold for aerobic to anaerobic switch at 2mmol/litreLactate shuttle hypothesis Maximum heart rate formula: 220 - age in yearsCooper test for VO2max estimationWalking test for VO2max estimation🎙️AboutFit For Science is a deep-dive podcast hosted by two biological data scientists, Rob and Stephan, exploring the intersection of research, health tech, and data-driven lifestyle design.
