Learn why a professional VO2max test is a game-changer for understanding your cardiovascular fitness, offering far greater accuracy than fitness trackers. This article dives into the unique advantages of precise VO2max assessments and how they can elevate your training and well-being.
The terms V, O2 and max stand for Volume, Oxygen, and maximum, indicating the highest oxygen consumption your body can achieve. The VO2max value, measured in milliliters per minute per kilogram, reflects how efficiently your body absorbs and uses oxygen during maximum effort1.
Why is that important? Because oxygen is required to create energy in the muscles. The amount of oxygen your muscles get depends on how well you can absorb it (respiratory system), how well your body distributes it (cardiovascular system), and how efficiently your muscles (and its mitochondria) can use it (musculoskeletal system). The intricate interplay of these systems paints a clear picture of your systemic health and longevity. Studies 2 suggest that cardiovascular health and longevity are two sides of the same coin. If cardiovascular aging is slow, meaning heart and blood vessels are healthy, it is very likely that overall aging will also be slow. That means joints, muscles, skin, and everything else in the body stay healthier for longer.
In short, VO2max is the most representative metric of your health and longevity.
Researchers found a stark difference between actual VO2max values and estimates provided by most smartwatches 3. The problem is that tracking devices don’t have a sensor to directly measure one’s oxygen intake. Instead, they gather data such as heart rate and running speed 4. Algorithms then compare this information with estimation charts to approximate a VO2max value. Since this process relies on database averages, the results are often imprecise - even in high-end smartwatches 5.
Since fit people have stronger heart muscle, they pump more blood in one stroke than unfit people. Therefore, the muscles get more oxygen (and hence more energy) per heartbeat. So, to keep up a given running speed, an untrained heart must beat at a higher rate than a fit heart. Because of this, smartwatches tend to overestimate unfit athletes and underestimate fit athletes.
For sedentary people - proverbial couch potatoes - a highly accurate VO2max test is probably overkill. These people would benefit from simply moving around more in their everyday lives. However, for anyone aiming to extend their health- and lifespan, let alone achieve peak health, a precise VO2max test is invaluable. Besides the sought-after number, a professional test will reveal other valuable insights into your health:
All these parameters, derived from the test, provide extensive analysis of your cardiovascular health and endurance. Professional coaches use these data to design tailored programs, whether your goal is endurance-, performance-, longevity-, or weight-based. Regardless of your goal, a high VO2max makes you look and feel younger and livelier.
A professional VO2max test uses specialized equipment 8 to precisely measure oxygen consumption during exercise.
The most reliable method, known as "respiratory gas analysis," involves wearing a mask that captures exhaled gasses as exercise intensity gradually increases. These gasses are sent through tubes to gas analyzers that assess oxygen intake and carbon dioxide output every 30 seconds. This process, called “Spiroergometry” 9, is also used by doctors to evaluate cardiovascular limitations through VO2 data.
Expect a seamless experience guided by our knowledgeable sports scientists. You’ll pedal on a stationary bike, wearing a specialized mask connected to high-precision gas analyzers that capture your breathing. As intensity increases, we track real-time data on your oxygen use and cardiovascular performance.
With this state-of-the-art assessment, our experts offer a full analysis and guidance - a powerful first step to take your fitness, health and longevity to the next level. If that sounds like a worthwhile endeavor to you, book your test as part of a holistic assessment at AYUN today. We can’t wait to help you become the fittest and most energetic version of yourself.

You are 44 years old. Sharp, organised, high-functioning. But lately you cannot find the word you are looking for mid-sentence. You wake at 3am and lie there for an hour. You are eating the same way you always have, but your waist is changing. Your hair is coming out in the shower. You feel like yourself but not quite yourself. Your GP ran blood work and said everything looks normal.What you may be experiencing are the early signs of perimenopause and they are some of the most commonly searched and least explained symptoms in women’s health. Brain fog, hormonal hair loss, night sweats, weight gain that does not respond to diet: these are not random. They are biological signals, each one pointing to a specific process that is shifting in your body. Understanding what is behind each symptom changes everything about what you can do about it.

You eat well, stay active, and still your body begins to change. Your cycle becomes irregular, your period may disappear, or your weight increases despite doing everything “right.” Many women experience this combination without a clear explanation for a long time. Often, the cause is not lifestyle alone, but a deeper hormonal imbalance, such as PCOS.

You eat well, exercise regularly, and still your body seems to be changing in ways that are hard to explain. The scale barely moves or even goes up, despite your efforts. At the same time, your cycle becomes irregular or your period stops altogether. Many women first assume stress or diet is to blame. But often, there is an underlying hormonal cause, such as PCOS.
