Durability：第1回「スタミナ」という言葉の嘘。従来の持久力モデルが持つ致命的な死角と『4つの科学的新定義』

The second public session will be held on June 6th, 2026 (Saturday) at 6:00 PM! For those who can't wait, early access is available for members! "He has stamina," "He lacks tenacity in the second half"—these are phrases we use casually every day, but scientifically speaking, they are very vague and may be hindering our growth. This is the first of a six-part series, "The Science of Durability (Physiological Endurance)." This time, we will uncover the fatal "blind spot" in the "Joyner model (maximum oxygen uptake × lactate threshold × running economy)," which has long been considered an unshakeable truth in sports science. Then, based on the latest paper published by Dr. Meixner et al. in 2025, we will rigorously redefine the previously lumped-together concept of endurance into four independent terms: "Durability," "Fatigability," "Repeatability," and "Resilience (physiological resilience)." From an era of chasing static "maximum values" to dynamic "management of performance decline." A paradigm shift that will change your running starts here. Meixner, B. J., et al. (2025). "Durability, fatigability, repeatability, and resilience in endurance sports: definitions, distinctions, and implications." Journal of Applied Physiology. Don't Study Just Run🎬 Episode 0: Guidance "Why is there a huge debate about 'Durability' around the world right now?" Presenting the overall storyline of the series and the limitations of conventional performance prediction models. A journey to unravel the truth about your performance decline begins.    • Durability：あなたの「30kmの壁」は根性のせいじゃない。マラソン後半の失...   📘 Episode 1: Limitations of Endurance Models and Four Scientific Definitions Discarding the ambiguous term "stamina," we strictly redefine it into four elements: Durability, Fatigability, Repeatability, and Resilience (physiological resilience).    • Durability：第1回「スタミナ」という言葉の嘘。従来の持久力モデルが持つ致命...   📘 Episode 2: Durability as a Performance Indicator and its Application to "Talent Identification" What is the true talent—the ability to not collapse in the second half—that has been overlooked in conventional tests? We explain the decisive boundary between elite and sub-elite runners, as revealed by fatigue tests (second tests).    • Durability：第2回真の「才能」は後半に現れる。エリートと凡人を分ける『疲労...   📘 Episode 3: "Nonlinear Collapse" Caused by Running at Marathon Intensity for 2 Hours How do the body's V₂O₂max and fuel efficiency (RE) collapse when an elite amateur runner with an average time of 2 hours and 46 minutes runs at marathon intensity for 2 hours? We delve into the reality of the terrifying "domain slip."    • Durability：第3回2時間走の恐怖。エリート市民ランナーの体内を襲う「非線形...   📘 Episode 4: The Trap of "Evaluation Methods" and the True Killer Indicator Proven by London Marathon Actual Data. We present the trap of heart rate drift (decoupling) and the true killer indicator that separates the sub-3 hour marathon group: "% Δ sLT (Percentage Decrease in Lactate Threshold Speed ​​under Fatigue)."    • Durability：第4回なぜ心拍ドリフトはタイムを予測しないのか？疲労下の「sL...   📘 Episode 5: What Determines Durability? How Can It Be Improved? A Series Summary. "Mechanical Defense" through high-weight, low-rep strength training and "Metabolic Defense" through high-carbohydrate intake (60-90g per hour). We explain specific practical menus to improve endurance.    • Durability：第5回後半の失速を防ぐ科学的対策。「高重量筋トレ」と「糖質戦略...
