The maximum rate at which the body can take in and use oxygen during intense exercise.
Why VO2 max matters
VO2 max is one measure of cardiorespiratory fitness, but it does not describe every aspect of health or endurance performance.
A practical example
A laboratory test measures oxygen use as exercise intensity progressively increases.
Common mistake
Comparing watch estimates between people as though they were identical laboratory measurements.
Keep the context in mind.
Training and nutrition terms describe general principles. The right exercise, intensity or food target still depends on your experience, health, goals and schedule.
Personalised coaching
Apply the principle to your own training.
A definition is useful, but your programme still needs to match your experience, schedule, recovery and goals.
