A Woman having a TELOMYX VO2 Max Test

A VO₂ max test is the gold-standard way to understand your aerobic limits,  then break through them.

It provides precise measurements of your aerobic capacity, heart-rate response, and training thresholds, allowing you to see exactly how efficiently your body uses oxygen — and where your endurance is improving, stalling, or limiting performance.

Whether your goal is breaking PBs, improving race performance, boosting cardiovascular health, or supporting long-term longevity, a VO₂ max test gives you objective data to train at the right intensities, recover properly, and progress with purpose rather than guesswork.

What is a VO2 Max Test?

A VO₂ max test is a medical-grade cardiopulmonary assessment that measures how efficiently your body uses oxygen during exercise. Originally developed for clinical medicine and adopted by elite endurance athletes, it has long been the reference method for optimising endurance and performance.

Unlike algorithm-based wearables and watches, which estimate VO₂ max from pace and heart rate, a true VO₂ max test directly measures your oxygen uptake, ventilation, and physiological thresholds in real time. This produces precise, individualised training zones that reflect how your body actually responds to exercise — not population averages or assumptions.

VO₂ max testing removes the guesswork, showing you exactly where your aerobic base, threshold, and high-intensity limits truly sit, so every training session has a clear purpose and delivers real adaptation.

Who would benefit from a VO2 Max Test?

A VO₂ max test isn’t just for elite athletes, it’s for anyone who wants to train smarter, improve endurance, and protect long-term heart health.

Most people go too fast on easy days and too slow on hard days.

A VO₂ max test defines your true training zones, showing the exact heart rates you should use for low-intensity, moderate, and high-intensity sessions. This removes guesswork and ensures every workout delivers the maximum cardiovascular benefit.

Not all VO2 Max Tests are made equal

Most people know that smart watches only estimate VO₂ max. What’s less well known is that many modern VO₂ max providers still rely heavily on algorithms to interpret test data.

Accurately identifying training zones requires experience and clinical judgement, not just software. We’ve tested algorithm-led systems extensively and, while they perform slightly better than consumer wearables, they remain less accurate than the comprehensive analysis used in clinical and hospital settings.

We do things differently.

Every VO₂ max test is manually analysed by a trained specialist. We generate and interpret key physiological graphs, including V-slope, ventilatory equivalents (VE/VO₂ and VE/VCO₂), respiratory exchange ratio (RER), heart-rate response, and oxygen uptake kinetics, to precisely identify your true aerobic and anaerobic thresholds.

The result is training zones based on your actual physiology, not estimates or population averages.

Why Knowing Your Physiological Thresholds Matters for Cardiovascular Training

Your physiological thresholds determine how hard you should train to improve, not just how hard you can train. Without them, many people train hard and consistently, yet plateau, putting in the effort without triggering the right physiological adaptations. 

 

By accurately identifying aerobic and anaerobic thresholds, training becomes targeted and efficient: easy sessions build endurance, hard sessions drive performance, and recovery is protected. 

 

This is why athletes rely on threshold-based training: it accelerates progress, reduces wasted effort, and turns hard work into faster improvements and personal bests.

Health Benefits of Monitoring VO2 Max

VO₂ max is one of the strongest indicators of cardiovascular health and long-term survival. Monitoring it over time provides a clear, objective measure of how well your heart, lungs, and muscles work together—and how effectively your training and lifestyle choices are improving your health.

🛡️

Early Warning Signal

A declining VO₂ max can reveal reduced cardiovascular capacity before symptoms appear, prompting earlier intervention through training, lifestyle, or medical review.

Objective Fitness Tracking

Unlike weight or subjective effort, VO₂ max provides a precise, reproducible marker of aerobic fitness—allowing you to track real physiological change over time.

🧠

Cardiovascular Health & Longevity

Higher VO₂ max is strongly associated with lower risk of cardiovascular disease and all-cause mortality. Improvements reflect better heart function, oxygen delivery, and metabolic health.

Smarter, Safer Training

Knowing your VO₂ max and related thresholds ensures training intensities are appropriate, maximising benefit while reducing unnecessary strain, overtraining, and injury risk.

What will I learn from a VO2 Max Test?

VO2 Max

Your VO₂ max measures how efficiently your body can deliver and use oxygen during exercise. It’s one of the strongest predictors of cardiovascular fitness and long-term health. Knowing your true VO₂ max lets you track real fitness improvements over time and objectively assess whether your training is actually raising your performance ceiling (the foundation for faster PBs and improved longevity).

Aerobic & Anaerobic Thresholds

Rather than just telling you how fit you are, a VO₂ max test identifies your key physiological thresholds  (the points where your body shifts from sustainable aerobic work to increasingly anaerobic effort). These thresholds determine how hard you can go for a given duration. Training around them is how athletes improve race pace, delay fatigue, and make meaningful gains in endurance while reducing unnecessary strain on the heart.

Training Zone

Based on your thresholds, we calculate precise heart-rate training zones tailored to your physiology (not population averages or algorithms). This ensures easy sessions stay truly easy and hard sessions are hard enough to drive adaptation. Training in the correct zones is how you improve faster, avoid plateaus, and accumulate fitness safely, whether your goal is performance, fat loss, or long-term cardiovascular health.

Recovery Analysis

A VO₂ max test also reveals how quickly and effectively your body recovers from exertion. Poor recovery can limit progress even when training volume is high. Understanding your recovery response helps you balance intensity and rest, reduce injury and burnout risk, and ensure each session builds fitness rather than breaking you down (critical for consistent PBs and sustainable health gains over time).

Understand how your body fuels itself

Train at the Intensities That Actually Burn Fat

This chart shows exactly how much fat you burn at different exercise intensities. Rather than guessing or relying on generic “fat-burning zones,” you can see where your body is most efficient at using fat as fuel. Training at these intensities improves fat oxidation, helps preserve carbohydrate stores, and supports longer, more sustainable efforts  (key for endurance performance and long-term metabolic health).

Understand How Your Body Fuels Performance

As intensity increases, your body gradually shifts from fat to carbohydrate as its primary fuel source. The effective fat burn chart shows where this transition happens for you. Understanding this shift explains why some efforts feel sustainable while others lead to rapid fatigue, and helps you structure training sessions that build endurance, improve efficiency, and reduce the risk of hitting the wall.

Train to Support Metabolic Health, Not Just Calories Burned

Calories alone don’t tell the full story. This analysis reveals whether your body is metabolically flexible, i.e. able to switch efficiently between fat and carbohydrate depending on demand. Improving this flexibility through targeted training is linked to better insulin sensitivity, improved cardiovascular health, and more consistent training adaptations, especially as you age.

Build a Race Fuelling Plan Based on Your Physiology

By showing when carbohydrate becomes the dominant fuel, this chart helps you plan race fuelling with precision. You can identify when external carbohydrate is likely to be required, how hard you can work before fuelling becomes critical, and how to avoid both under-fuelling and unnecessary intake. The result is steadier energy, fewer GI issues, and better performance when it matters most.

How we analyse your test

A VO₂ max test generates a wealth of high-quality physiological data that can be used to improve both performance and long-term health, but only if it’s analysed correctly.


Throughout your test, we collect multiple metrics including oxygen uptake, carbon dioxide production, ventilation, heart rate, and substrate utilisation. Rather than reducing this to a single headline number, we plot these variables across the full intensity range of the test and analyse them together using established physiological models.


By interpreting these graphs in combination, we accurately identify your key physiological thresholds and personalised training zones. These form the foundation for smarter training, allowing you to target the right intensities, accelerate progress towards PBs, and build cardiovascular fitness in a way that supports longevity, not burnout.
