Knowing how to measure and train close to your VO2Max may lead to big performance gains. But what is VO2Max and what's the best way to use it? We also discuss the latest developments around rugby's smart mouthguard and the announcement by World Athletics that they are trialling a new way of measuring the long jump which involves a take-off zone rather than a take-off mark. And no, it's not an April Fools joke!

Full of holes and errors, a bit of misunderstanding, and some outright dishonesty, which we tried to explain and address in the show The paper on the sub-2 hour marathon physiology that shows how those elite runners can get to 90% of VO2max for two hours A more lay explanation of the 2 hour marathon, again discussing how close to max elites can run Paper on how different durations of interval training affect Power, HR and RPE, which may be useful to guide your choice of interval session structure The research study that shows how 8 min blocks at close to VO2max improves VO2max and performance, and that the more time you spend close to VO2max, the greater the benefit Get bonus content on Patreon Hosted on Acast.
