Aerobic Power: VO2 max and vVo2max
Summary:
- In Ep. 8, the coaches define the difference between V02 max and vV02 max, discuss the benefits of training to improve both metrics, what it means in a racing environment and offer some tips for performance-based athletes.
Key Discussion Points:
- Addressing Common Misconceptions:
- A higher VO₂ max guarantees better race results
- VO₂ max is the best single metric to track
- vVO₂ max is just a lab number
- Deep Dive:
- Central Capacity vs Usable Speed
- What vVO₂ Max Actually Represents
- Muscle-Level and Metabolic Factors
- Fractional Utilization and Fatigue Resistance
- Neuromuscular and Mechanical Efficiency
- Webinar Pitch, Outro & Feedback
- Training Takeaways

Actionable Takeaways:
- Train VO₂ max to build capacity, but don’t live there year-round.
- Use vVO₂ max–focused work to raise race-relevant speed, improve efficiency under stress and make fitness usable.
- If your aerobic fitness is high but your speed isn’t improving, efficiency (not capacity) is likely the bottleneck.
