VO2 Master removed the €20,000–€40,000 barrier of lab-based carts overnight. Its accessibility, portability, and real-world applicability let me launch Rua Laboratories without compromising data quality. Now every client, from recreational to elite, receives VO2 and ventilatory analysis as part of their performance profile. Quite simply, Rua Laboratories wouldn’t exist today without it. Thank you VO2 Master!

“VO2 Master allows me to test clients anywhere, bringing laboratory precision to real-world settings. It bridges the gap between science and everyday performance. In the Middle East, where lifestyle-related illnesses are growing, having accurate metabolic data is essential. VO2 Master makes that possible and empowers people to take measurable control of their health and longevity.”
I have been using the VO2 Master for measuring oxygen uptake during body bearing Tabata exercise because of its portability and accuracy.

The VO2 Master’s ease of use and portability make it invaluable in both lab and field settings. It enhances our research capabilities and student engagement by bringing charts and numbers to life in a hands-on, practical way. This technology allows us to seamlessly demonstrate how to measure one of the most important markers of fitness. It’s a vital tool in both our sports science research and our teaching of undergraduate, graduate, and medical students.

When my clients see the objective data around cardio from VO2 Master testing they are motivated to take it seriously.
Clients have reached out to me because I’ve talked about VO2 max testing and then by doing it and explaining their results and individualizing their training, of course there’s an interest in all the other pieces that fit into the fitness puzzle which is obviously great for business, and great for my sense of purpose as a coach to help people reach great results.

I have been using VO2 Master for almost 4 years now and have completed almost 1500 tests. The most important features for me were validity and applicability to real-world settings—whether that’s in the lab, on the field, or overseas. The analyzer is incredibly portable, comfortable for athletes, and fast to set up. I also rely on its seamless integration with technologies like Moxy, heart rate sensors, Core Temp, and power meters. This company is definitely bridging the science and practice gap with an elegant yet practical design and powerful data.

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.

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. 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.

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.

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. Read Less

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.

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!
