VO2 Master is changing the landscape of human performance testing globally.

We, as a team of physiologists and coaches, have been using VO2 Master to support the performance of amateur athletes since August 2020. I must say that as a researcher, VO2Master allowed us to reach the perfect balance between precise data collection and real-life sport practice (something which is unconceivable via standard lab equipment).
Furthermore, as we are based in Argentina, the team of VO2Master was extremely helpful at accommodating my needs when the time came to perform the equipment’s annual service.

VO2Master has helped us to develop an accurate testing system also for the high-elite athletes and also for those with a big interest for sports. If you choose a simple to use -model for testing we can only warmly recommend! The data supports the other measurements of our check-ups and we can give the report rightaway on our customers. The crew of VO2Master was brilliant as well by giving the yearly service – the necessary updates and new device came already when we were still testing with the former one – so no need for testing breaks/weeks! Thank you!

Knowing and using VO2 Master has allowed us to be able to evaluate and monitor our athletes both to improve their sporting performance and for research purposes. VO2 Master has become an indispensable tool for optimising our training, projects and studies.

I was like nobody back then, and I believe many people thought the VO2 Master was just a cool accessory and not an advantage in training. VO2 Master is super useful, it’s like taking the lab out to the training field where I train day to day. Being in a lab is great but its not the environment where I perform and the VO2 Master allows me to get accurate measurements, out there wherever I train, to get the numbers I get.

The VO2 Master Analyzer has been an incredibly impactful tool for us. Digging deeper into rider physiology has provided an inciteful contribution to understanding the rider-bicycle interaction.

I started using the VO2 Master Analyzer in 2017, to get a better understanding of what’s happening during test sessions and to dial-in my energy system for different training distances. I use the VO2 to learn how my engine is working and to identify weaknesses that need improvement. The simplicity and ease of use with the lightweight design will give more coaches and athletes the same benefits that I have had for years.

Kristian Blummenfelt
Triathlete - Olympic and Ironman World Champion, Co-Founder of Santara Tech

We chose the VO2 Master Analyzer after a thorough screening of the 6 leading metabolic analyzers available on the market. Based on the process that we went through we needed to find a great compromise between an accurate and reliable device that the athletes actually like to use and the VO2 Master Analyzer is the only metabolic analyzer that allows us to measure freely wherever we are with basically the same level of technology that are in the metabolic carts in the laboratory.

The nature of our research with tactical personnel requires that we conduct most of our work in dynamic and often austere environments while these personnel are doing highly physical tasks. While capturing energy expenditure is often a key requirement, pragmatically we have not been able to do this given the requirement for bulky, generally static, equipment. The VO2 Master has been a game changer. Being so small and portable we have been able to use it in a variety of projects, from mounted police on horseback to specialist police conducting occupationally specific capability testing. Best of all it works easily with some of our other equipment (e.g., polar HR monitors) and iPads and allows use to monitor and show other researchers and personnel data in real-time.

The VO2 Master Analyzer enables our team to evaluate athletes on the water, which provides specific insight needed to really understand their physiology. We intend to use the information to help design individualized training programs.

Measuring Economy with VO2 Master enables me to select the fastest wetsuit for an athlete on an individual basis. My athletes can increase their swimming efficiency without increasing training volume.

My Lab conducts physiological research in the field with firefighters and other tactical populations. The ability to accurately assess physiological responses of tactical operators in working conditions has been very challenging due to a lack of cost effective, validated device options. However, VO2Master has changed the game by providing practitioners and researchers with an invaluable, low profile tool to evaluate operator readiness.

Our lab had wanted a portable metabolic analyzer for a long time but never had the means to purchase one, until we came across VO2 Master. After roughly 75 tests, we’re pretty pleased with the VO2 Master Pro’s performance.
