We’ve all got one, but what does it actually mean, and does the number your smart watch gives you actually matter? This week on The Shakeout Podcast we're setting out to understand the science of VO2 Max, a metric that seems to be everywhere in the saturated world of endurance training advice. From its correlation to performance to its proven effects on longevity, VO2 Max might be one of the most all encompassing indicators of fitness available. But is a higher number always better? And if more is better how do we go about raising ours?Joining the show to lend his expertise is Dr. Mick Leahy, professor of cardiovascular exercise physiology at The University of British Columbia. As an expert on all things aerobic, Mick walks us through the science behind VO2 Max, shedding light on what the term actually means, what the hype around VO2 Max is all about, and how runners can use the metric to improve their performance on race day.
