It’s a measure of the maximal ability of your body to take in and use oxygen. But what does the number actually mean for your health and longevity? Why is it important to know your VO₂max? What’s the most effective way to improve your VO₂max, whether you’re an athlete or just someone seeking to improve your health? And what does this all have to do with beer-league hockey, and everybody’s favourite Sudbury Blueberry Bulldog, Shoresy? In this episode, Stuart Phillips asks Martin Gibala to break down VO₂max in plain English: what it is, why it matters, and how it shapes everything from your risk of dying to how fast you can run a 10K. And just to get the kin grad students among us even more excited, this episode namedrops the Hickson Protocol, plus legends of kinesiology like Robert Ross, Ulrik Wisløff and Carsten Lundby.

And then here’s a 2019 case study from Lundby and Joyner that references the physiological profile of Norwegian cyclist Oskar Svendsen, who recorded a staggering 96.7 mL/kg/min in a laboratory.
