Episode notes
VO2 Max Determinants
- VO2 max is determined by cardiac output, blood oxygen capacity, and oxygen extraction.
- Cardiac output and oxygen extraction improve with training, but oxygen extraction is naturally high.
Dan's VO2 Max Improvement
- Dan's VO2 max improved from 75 to 80 over several years of training.
- This demonstrates that VO2 max can improve with training, even after years of training.
Trainability of VO2 Max
- While VO2 max is trainable, it is less trainable than other performance determinants like thresholds and running economy.
- A high VO2 max is necessary for elite endurance running, but other factors also play a crucial role.
