如何提升耐力：基于科学的指南
摘要
本期节目深入剖析耐力训练的神经科学与生理学原理，阐释神经系统、肌肉、血液、心脏和肺部如何共同影响运动表现。Andrew Huberman 概述了四种不同类型的耐力——肌肉耐力、长时间耐力、无氧HIIT和有氧HIIT——并为每种类型提供了具体的训练方案。他还涵盖了燃料来源、补水策略以及支持耐力表现的关键补剂。
核心要点
- 放弃是神经层面的，而非身体层面的 —— 脑干中释放epinephrine（肾上腺素）的神经元（蓝斑核）决定你是否继续或停止努力；大脑比身体先放弃。
- 存在四种不同类型的耐力，每种都需要不同的训练方案，并针对不同的生理系统进行训练。
- 肌肉耐力通过3–5组、每组12–100次的训练来构建，主要采用向心运动，尽量减少离心负荷。
- 长时间耐力（持续12分钟以上的努力）能够增加肌肉内的mitochondrial density（线粒体密度）和毛细血管床。
- 无氧HIIT突破VO2 max（最大摄氧量）上限，训练线粒体使用更多氧气并改善神经肌肉能量获取。
- 采用1:1运动与休息比（例如，反复跑一英里）的有氧HIIT能显著提升心脏每搏输出量、脑血管以及整体ATP产生。
- 体重中仅1–4%的水分流失就会导致工作能力下降20–30%，并损害认知功能。
- Galpin方程式：体重（磅）÷ 30 = 每15分钟运动应饮用的盎司数。
- 咖啡因和苹果酸镁是耐力表现与恢复方面证据支持最充分的补剂。
详细笔记
影响耐力的五大系统
所有耐力表现都取决于五大系统的相互作用：
- 神经 —— 神经元向肌肉发出收缩信号，并决定继续努力的意愿
- 肌肉 —— 能量利用和疲劳的主要发生部位
- 血液 —— 输送葡萄糖和氧气作为燃料
- 心脏 —— 泵送含氧血液；每搏输出量是关键的表现变量
- 肺部 —— 提供燃料燃烧所需的氧气
燃料来源与ATP产生
身体根据运动强度和持续时间，按顺序调用多种燃料来源：
- Phosphocreatine（磷酸肌酸） —— 最先使用；为短暂的高强度爆发提供能量（数秒）
- Glucose（葡萄糖）（血糖）—— 可立即获取，尤其在近期摄入碳水化合物后
- Glycogen（糖原） —— 储存在肌肉中的碳水化合物
- 脂肪酸 —— 在长时间或空腹运动中从脂肪组织动员
- Ketones（酮体） —— 适用于已适应生酮饮食的人群
氧气本身并非燃料，但对于将所有这些底物转化为ATP至关重要。神经元需要葡萄糖（或酮体）、钠、钾和镁来激发放电并维持努力。
中枢调控机制与意志力
- 脑干中一组名为**locus coeruleus（蓝斑核）**的神经元在努力过程中释放肾上腺素
- 当这些神经元停止活动时，努力也随之停止——这一点在发表于《Cell》杂志的一项研究中得到了证实
- 肾上腺素作为准备就绪信号发挥作用；水平越高，努力越持续；水平降低则允许休息
- 表现被描述为”100%由神经系统决定”——心理与身体的区分是一种错误的二元对立
类型一：肌肉耐力
- 定义：肌肉反复做功直至局部肌肉疲劳（而非心血管疲劳）导致力竭的能力
- 方案：3–5组 × 12–100次（12–25次最为实用），组间休息30–180秒
- 关键原则：尽量减少离心（下放）负荷——保持下放阶段轻松且相对快速
- 示例：俯卧撑、引体向上、壶铃摆动、平板支撑、靠墙深蹲、等长收缩保持
- 机制：改善肌肉局部的mitochondrial respiration（线粒体呼吸）并增强神经肌肉控制
- 益处：支持长时间有氧运动表现，并建立姿势耐力
类型二：长时间耐力
- 定义：持续稳态努力12分钟至数小时（一个延长的”组”）
- 机制：增加肌肉内的毛细血管密度并提高mitochondrial density（线粒体密度）
- 原理：更多毛细血管 → 更多氧气输送 → 单位时间内更大的能量供给
- 益处：提高效率——随着适应性积累，相同的努力程度消耗的燃料越来越少
- 关键洞见：每次重复的长时间耐力训练都会使下一次在代谢上更加高效
类型三：高强度无氧耐力
- 定义：努力程度超过VO2 max（最大摄氧量）的100%；无法获取足够氧气来完全支撑能量需求
- 方案：3–12组；运动与休息比为3:1至1:5
- 示例（3:1）：30秒高强度努力 / 10秒休息
- 示例（1:5）：20秒高强度努力 / 100秒休息
- 何时使用1:5：当动作质量至关重要时（例如负重深蹲），较长的休息时间可保障安全的动作模式
- 何时使用3:1：技术要求较低的动作（例如强攻自行车、划船机），动作变形的风险较低
- 频率：每周约2次
- 机制：训练线粒体更高效地利用氧气；提高神经肌肉能量招募；一定程度的毛细血管发育
- 迁移效果：有益于团队运动、冲刺、网球对抗——任何需要高强度爆发的活动
类型四：高强度有氧耐力（有氧HIIT）
- 定义：在接近最大摄氧量强度下进行的高强度间歇，休息时间相等——有氧（有氧气参与）
- 方案：3–12组；1:1运动与休息比
- 示例：跑1英里（约7分钟），休息7分钟，重复共计4英里以上
- 核心益处：显著增加心脏每搏输出量 —— 由于回心血量增加，心脏左心室经历离心负荷，导致心肌增厚并每次跳动泵出更多血液
- 下游效应：向肌肉和大脑输送更多氧气和葡萄糖；改善认知功能、记忆力（海马体血管系统）和专注力
- 值得注意的发现：即使从未以完整比赛距离训练过，此方案也能帮助运动员完成半程马拉松或全程马拉松
心血管与大脑适应
- 心脏：心肌壁离心负荷带来的每搏输出量增加
- 大脑：支持记忆（hippocampus，海马体）、呼吸、专注和努力的脑区毛细血管密度增加
- 注意：力量/Hypertrophy 肌肥大（肥大）训练在血液含氧量或每搏输出量方面的益处，不如耐力训练显著
补水方案
- 运动中的水分流失：每小时1–5磅（高温和高强度条件下更高）
- 体重中1–4%的水分流失 = 工作能力下降20–30% + 认知损害
- Galpin方程式：体重（磅）÷ 30 = 每15分钟运动应饮用的盎司数
- Electrolytes（电解质） —— 钠、钾和镁至关重要；大量饮水而不补充Electrolytes 电解质可能带来危险

How to Build Endurance: A Science-Based Guide
Summary
This episode breaks down the neuroscience and physiology of endurance, explaining how the nervous system, muscles, blood, heart, and lungs each contribute to performance. Andrew Huberman outlines four distinct types of endurance — muscular, long-duration, anaerobic HIIT, and aerobic HIIT — and provides specific training protocols for each. He also covers fuel sources, hydration strategies, and key supplements that support endurance performance.
Key Takeaways
- Quitting is neural, not physical — neurons in the brainstem (locus coeruleus) releasing epinephrine govern whether you continue or stop effort; the mind quits before the body does.
- There are four distinct types of endurance, each requiring different protocols and training different physiological systems.
- Muscular endurance is built with 3–5 sets of 12–100 reps using mainly concentric movements with minimal eccentric loading.
- Long-duration endurance (12+ minutes of continuous effort) builds mitochondrial density and capillary beds within muscles.
- Anaerobic HIIT pushes beyond VO2 max, training mitochondria to use more oxygen and improving neuromuscular energy access.
- Aerobic HIIT using a 1:1 work-to-rest ratio (e.g., mile repeats) strongly improves heart stroke volume, brain vasculature, and overall ATP production.
- Losing just 1–4% of body weight in water causes a 20–30% drop in work capacity and impairs cognitive function.
- The Galpin Equation: bodyweight (lbs) ÷ 30 = ounces to drink every 15 minutes of exercise.
- Caffeine and magnesium malate are the most evidence-supported supplements for endurance performance and recovery.
Detailed Notes
The Five Systems That Govern Endurance
All endurance performance depends on the interaction of five systems:
- Nerve — neurons signal muscles to contract and determine willingness to continue
- Muscle — primary site of energy utilization and fatigue
- Blood — carries glucose and oxygen as fuel
- Heart — pumps oxygenated blood; stroke volume is a key performance variable
- Lungs — deliver oxygen for fuel combustion
Fuel Sources and ATP Production
The body draws on multiple fuel sources in sequence depending on effort intensity and duration:
- Phosphocreatine — used first; powers short, intense bursts (seconds)
- Glucose (blood sugar) — available immediately, especially from recent carbohydrate intake
- Glycogen — stored carbohydrate in muscles
- Fatty acids — mobilized from adipose tissue during prolonged or fasted effort
- Ketones — available for those who are ketogenic-adapted
Oxygen is not a fuel but is essential for converting all these substrates into ATP. Neurons require glucose (or ketones), sodium, potassium, and magnesium to fire and sustain effort.
The Central Governor and Willpower
- A cluster of neurons in the brainstem called the locus coeruleus releases epinephrine during effort
- When these neurons shut off, effort stops — this was demonstrated in a study published in Cell
- Epinephrine functions as a readiness signal; higher levels sustain effort, lower levels permit rest
- Performance is described as “100% neural” — the mental/physical distinction is a false dichotomy
Type 1: Muscular Endurance
- Definition: Ability of muscles to perform repeated work until local muscular fatigue (not cardiovascular fatigue) causes failure
- Protocol: 3–5 sets × 12–100 reps (12–25 is most practical), rest 30–180 seconds between sets
- Key rule: Minimize eccentric (lowering) loading — keep the lowering phase light and relatively quick
- Examples: Pushups, pull-ups, kettlebell swings, planks, wall sits, isometric holds
- Mechanism: Improves mitochondrial respiration locally within muscles and strengthens neuromuscular control
- Benefit: Supports long-duration cardio performance and builds postural endurance
Type 2: Long-Duration Endurance
- Definition: Continuous steady-state effort for 12 minutes to several hours (one extended “set”)
- Mechanism: Builds capillary density within muscles and increases mitochondrial density
- Why it works: More capillaries → more oxygen delivery → greater energy availability per unit time
- Benefit: Increases efficiency — the same effort burns less fuel over time as adaptations accumulate
- Key insight: Every repeated long-duration session makes the next one more metabolically efficient
Type 3: High-Intensity Anaerobic Endurance
- Definition: Effort exceeding 100% of VO2 max; no oxygen available to fully support energy demands
- Protocol: 3–12 sets; work-to-rest ratio of 3:1 to 1:5
- Example (3:1): 30 seconds hard effort / 10 seconds rest
- Example (1:5): 20 seconds hard effort / 100 seconds rest
- When to use 1:5: When form quality matters (e.g., weighted squats), longer rest preserves safe mechanics
- When to use 3:1: Low-skill movements (e.g., assault bike, rowing) where form degradation risk is lower
- Frequency: ~2× per week
- Mechanism: Trains mitochondria to use oxygen more efficiently; increases neuromuscular energy recruitment; some capillary development
- Carryover: Benefits team sports, sprinting, tennis rallies — any activity with high-intensity bursts
Type 4: High-Intensity Aerobic Endurance (HIIT Aerobic)
- Definition: High-intensity intervals at or near VO2 max with equal rest — aerobic (with oxygen)
- Protocol: 3–12 sets; 1:1 work-to-rest ratio
- Example: Run 1 mile (~7 min), rest 7 min, repeat for 4+ total miles
- Key benefit: Strongly increases cardiac stroke volume — the heart’s left ventricle experiences eccentric loading from increased blood return, causing the cardiac muscle to thicken and pump more blood per beat
- Downstream effects: More oxygen and glucose delivered to muscles and brain; improved cognitive function, memory (hippocampal vasculature), and focus
- Notable finding: This protocol can prepare athletes to complete half-marathons or marathons even without ever training at full race distance
Cardiovascular and Brain Adaptations
- Heart: Increased stroke volume from eccentric loading of cardiac muscle walls
- Brain: Increased capillary density in areas supporting memory (hippocampus), respiration, focus, and effort
- Note: Strength/Hypertrophy 肌肥大 training does not produce the same degree of blood oxygenation or stroke volume benefits as endurance training
Hydration Protocol
- Water loss during exercise: 1–5 lbs per hour (higher in heat and high-intensity conditions)
- Losing 1–4% of body weight in water = 20–30% reduction in work capacity + cognitive impairment
- The Galpin Equation: Body weight (lbs) ÷ 30 = ounces of water per 15 minutes of exercise
- Electrolytes — sodium, potassium, and magnesium — are critical; excessive water without Electrolytes 电解质 can be dangerous
Supplements for Endurance
| Supplement | Use | Notes |
|---|---|---|
| Caffeine | Improves endurance and power output | Well-supported across modalities |
| Creatine | Loads phosphocreatine in muscles | Discussed in prior episodes |
| Beta-alanine | Supports moderate-duration work | Discussed in prior episodes |
| Magnesium malate | Reduces DOMS (delayed onset muscle soreness) | Different from sleep-supporting forms |
| Magnesium threonate / bisglycinate | Sleep support | Not the same as malate form |
