Your Body, Your Numbers

Precision metabolic testing reveals exactly how your body burns fuel, your personalised training zones and how you adapt to exercise intensity & duration
Train Smarter. Race Faster. Perform at your Peak.

What is VO₂max Testing?

VO₂max testing measures the maximum amount of oxygen your body can use during intense exercise. It’s the gold standard for assessing cardiovascular fitness and aerobic capacity.

But this is about much more than just a single number.

Our comprehensive metabolic test reveals a wealth of information including:

  • Your exact aerobic and anaerobic thresholds

  • Personalised heart rate training zones

  • How your body burns fat v carbs at different intensities

  • Your optimum fat burning zone (FatMax)

  • Precise race day fueling recommendation

 

Other VO₂ Test Options

VO₂ tests are available across a variety of intensities and durations, depending on your specific goals.

VO₂submax Testing

The VO2submax test measures how efficiently your body uses oxygen during exercise at submaximal effort levels – meaning you won’t be pushed to your maximum capacity. The VO2submax test stops at a lower intensity, making it a safer and more comfortable option for many individuals.

This test is ideal if you want to assess your aerobic fitness without the strain of maximal exertion. It’s especially suitable for beginners, older adults or those with health concerns who may find maximal tests too demanding. Despite being less intense, the VO2submax test provides valuable insights into your cardiovascular health and endurance capacity.

VO₂long Testing

The VO2long test is designed to measure your oxygen consumption over an extended period of exercise. Unlike short, maximal tests, this test focuses on your body’s ability to sustain aerobic activity for longer durations, providing insights into endurance and aerobic efficiency.

If you are an endurance athlete or training for long distance events, the VO2long test can help you understand how your body performs during prolonged exercise. It reveals how efficiently your muscles use oxygen over time and can identify endurance limitations or fatigue effects.

This test is typically carried out as a follow up to a VO2max or submax test.

FatMax Testing

The Fatmax test identifies the exercise intensity at which your body burns the most fat. This is the point where fat oxidation is maximized, making it a powerful tool for weight management, metabolic health and endurance training.

Understanding your Fatmax intensity allows you to optimise your workouts and nutrition to enhance fat burning.

Whether you’re an athlete looking to improve endurance or someone aiming to lose weight, this test provides personalised data to guide your training.

Frequently Asked Questions

What type of tests are there?

The VOsubmax test stops when your anaerobic threshold (known as LT2) has been passed. This is typically somewhere in the region of 70% to 80% of VO2max.

A VOmax test progresses to a maximum effort which stops when you signal you don't want to continue or your power/speed starts to fade with increased intensity.

A VOlong test spends an extended period of time at lower to moderate intensities to measure your fueling requirements over time in these zones. This is often used to mimic race conditions.

A FatMax test determines the optinum fat burning zones for workouts and this gives you heart rate ranges. the likely intensity for this will be a brisk walk, jog or easy running. You can progress from here to a VO2submax or VO2max test if you wish.

Can I use my own bike?

For bike tests you can use our stationary bike, bring your own bike to work with our turbo trainer or even bring your bike and turbo trainer to exactly replicate your own indoor training environment.

How often should I get a test done?

You can do it just once a season at the start of your training or approx every 8 to 12 weeks during the training and racing season if you want more frequent feedback and zone adjustments as you get fitter.

Who benefits?

Athletes who want to to have precise training zones for endurance and hard interval training.

Anyone who wants to monitor their VO for cardio fitness and to maximise their long term health.

Do I need to be super fit to do a VO₂ test?

No, the tests are designed for all fitness levels and will be adapted depending on your abilities. You simply go to a maximum effort (if you wish) - whatever that is for you.

Can I just use my smartwatch VO₂ estimate?

Smartwatches use algorithms based on heart rate and pace to estimate VOmax. We actually measure your oxygen and carbon dioxide levels in real time providing lab grade accuracy.
