The Physical Performance Show: Endurance Innovators: Dr Andrew Sellars & Peter O’Brien – Co-Founders VO2 Master

 In Podcast (The Physical Performance Show)

In episode 326 of The Physical Performance Show Brad Beer shares a conversation with Dr Andrew Sellars & Peter O’Brien – Co-Founders VO2 Master in this Endurance Innovators Edition.

In this episode we look into some of the hottest new technology in the endurance market. The VO2 Master Analyser is the world’s first wearable, easy to use metabolic analyser. We speak with founder Dr Andrew Sellars, Medical Doctor and self proclaimed passionate physiologist,  and co-founder and advisor Computer Scientist Peter O’Brien.

Many will have seen this device on the faces of Current World 70.3 Triathlon Champion Gustav Iden and his Norwegian counterpart Kristian Blummenfelt, current Olympic World Triathlon Series and World Ironman Champion who is regularly seen with the VO2 Master Analyser on his face during both indoor and outdoor training sessions.

Peter O’Brien and Dr Andrew Sellars share around the development of this technology and the reason why they felt it was necessary to develop the world’s first wearable and portable metabolic analyser. They outline why it is important for athletes to be able to measure their VO2 Max and their VO2 along with respiratory dynamics in order to make wise training decisions.
