I came across a conversation recently comparing VO\u2082max testing to power data from TrainingPeaks. It\u2019s a familiar debate and one I\u2019ve spent a lot of time thinking about. After running hundreds of VO\u2082max tests myself and coaching athletes across a range of abilities, I thought I\u2019d share my perspective.<\/p>\n\n\n\n
In short: TrainingPeaks peak power charts are more useful for most athletes than direct physiological testing. Five-minute power in particular is a surprisingly reliable proxy for VO\u2082max in well-trained individuals. But beyond that, power data tells you what matters most, what an athlete can actually do out in the real world.<\/p>\n\n\n\n
VO\u2082max has its place, of course. But it\u2019s not the be-all and end-all. Metabolic testing equipment is notoriously sensitive, and the accuracy of the results can vary far more than manufacturers claim. Unless you’re working with a skilled practitioner in a tightly controlled environment, you risk drawing conclusions from noisy or misleading data.<\/p>\n\n\n\n
By contrast, peak power charts are brutally honest. They\u2019re built from real efforts, in real conditions, with meaningful context: was it during a race? Were they fatigued? Was it off the back of a big week? That kind of data is gold for coaches and it\u2019s already in front of us if we know how to use it.<\/p>\n\n\n\n
What\u2019s more, this data evolves. It grows with the athlete. It reflects adaptation, plateaus, breakthroughs. It shows you the energy systems that need work and the durations where confidence is building. You simply can\u2019t get that from a single lab test.<\/p>\n\n\n\n
That\u2019s not to say physiology isn\u2019t important, it is. But its real power comes in solving specific questions or refining things at the sharp end. For the day-to-day of coaching and training, performance-based metrics like peak power give us more clarity, more consistency, and more direction.<\/p>\n\n\n\n
So while VO\u2082max still gets all the attention, I\u2019d argue the humble 5-minute power line on a TrainingPeaks chart is often doing the heavier lifting.<\/p>\n","protected":false},"excerpt":{"rendered":"
