VO2 Max Chart

In my efforts to become stronger runner, I have been looking much more into my VO2 Max progression. Whether I should ignore my VO2 Max completely or try to see how it improves over time. Here I am going to be talking about the effect of running on where you are on the VO2 Max Chart, using my experiences as the example.

Your VO2 Max is the amount of oxygen your body can process during exercise, this is your maximal oxygen consumption. The higher the your VO2 max score, therefore oxygen capacity, the fitter you are. 

How accurate is the VO2 max on a running watch?

Having an accurate VO2 Max output from a smartwatch can help athletes in all disciplines to maximize their performance without the need to visit a laboratory for a test

Different tests have indicated that a modern running watch has an accurate enough VO2 Max data point to be relied upon for training purposes.

A real world test by The Running Channel produced results within 5% of a lab test. This was with Garmin devices and a white paper from First Beat Technologies indicated 95% accuracy.

A recent paper from the Journal of Sports Medicine, testing the accuracy of a Garmin Forerunner 245 gave an average VO2 Max accuracy of within 5.7% of a laboratory test.

From these studies we can see that a good Garmin running watch can be used for tracking changes that your training has on your VO2 Max with a reasonably high degree of confidence. 

VO2 Max Frequently Asked Questions

What is VO2 Max?

Simply put, VO2 Max is defined as the maximum amount of oxygen that can be consumed by the body while exercising. It is measured in millilitres per kilogram per minute (ml/kg/min). The higher your aerobic capacity, the more physically fit you are. Professional athletes would tend to have a higher VO2 Max than non professional athletes and so the scale goes down to more sedentary people.

What is a good VO2 Max?

Ultra runner Kilian Jornet has had his VO2 Max tested at 89.5 ml(kg/min). The highest recorded number was an 18 year old Norwegian cyclist Oskar Svendson with 97.5

However there are extreme examples. A good VO2 max differs with age and sex. What is considered excellent for a 25 year old male would be considered superior for his 55 year old counterpart. Likewise if that same 25 year old male had a fair VO2 Max, that would be considered excellent for a 25 year old female.

The VO2 Max chart indicates what a good VO2 Max is for different age brackets for both men and women. A good VO2 max in both charts is the third row down. As you can see, what is considered good decreases with age. Someone in this bracket will typically be a fit and active individual.

What is a good VO2 Max for my age?

The VO2 Max chart has a column for various different age groups. If you are in the good, excellent or superior categories for your age group, then your VO2 Max is good for your age.

Just replace the placeholder text with your age and gender to see what a good VO2 max is for you.

What is the normal range for VO2 Max?

What is considered a good VO2 Max differs by sex and age. Male have a higher VO2 Max than females for a given age group. A normal VO2 Max range would be in the fair or good categories for your sex and age on the VO2 Max chart.

What should my VO2 Max be?

There is no single VO2 Max figure which can be quoted as what yours should be. Within your age range you should ideally be aiming for good, excellent or superior on the VO2 Max chart. This is achieved through a mixture of genetics, a healthy diet and lifestyle and regular aerobic activity.

How to improve VO2 Max with training?

You can improve your VO2 Max by training, but there is evidence to suggest it is limited by genetics as to how high it can go. Undertaking regular aerobic activity will allow you to increase your VO2 Max to its genetic ceiling. This can be as part of your running routine or via a cross training activity such as stationary bike workouts for runners.

How is VO2 Max measured?

There are three different ways that VO2 Max is measured.

Firstly, and the most accurate way is to undertake a laboratory test. This is measured using maximal exercise test on a treadmill or bike while connected to equipment capable of analyzing your expired air. It provides data on how much oxygen you use as you exercise, and determines the maximum level of oxygen that can be consumed during exercise, your VO2 Max. The drawbacks of this method are that you need access to the laboratory, although the testing costs, it is not a significant amount with labs advertising online. However if you want to get tested reasonably frequently to monitor your training progress, this could become a significant cost.

The second method for measuring VO2 Max is to use a running watch or Smart Watch. There is significant debate on the accuracy of the VO2 Max numbers these devices provide. However they do provide an estimate based on data used by their proprietary algorithms. 
The benefit of using a watch is that the figure is constantly monitored during your workouts. Assuming the watch uses the same information each time it calculates your VO2 Max, you will be able to monitor the improvements or otherwise by looking at the data. The actual VO2 Max figure may not necessarily be 100% accurate, but given all the data is measured in the same way, the trends should be reliable.

The third method of measuring your VO2 Max is to use a simple VO2 Max calculator. There are several published methods for calculating your VO2 Max, all of which are available to test on our VO2 Max calculator.

The largest benefit of this method is that no specialized equipment is required. Therefore it is available to anyone to test out.

How can I improve my VO2 Max with training?

The short answer is yes you can improve your VO2 Max with training. As you will read below I improved my VO2 Max by 18% over two years. However, the amount you can gain may be limited by genetics. 

A 2013 study (Orysiak et al., 2013) concluded that genetics can account for up to 50% of an individual’s VO2 Max. Once a person reaches their genetic VO2 Max,  oxygen uptake plateaus and their aerobic system switches to anaerobic power production, meaning without oxygen. A study of different research papers published in the CSF Journal concluded there were four genes that responded to training to improve VO2 Max. The response from these ranged from 2% improvement to a 7% improvement. Overall a study in 2010 (Keller et al., 2010) discovered that the average improvement in VO2 Max after 6 weeks of endurance training was 14%.

This is an amount that anyone that undertakes athletic endeavours should be pleased with. Indeed increasing your VO2 max to its genetic potential should be a goal of everyone if possible. Being as fit as your genetics will allow can only help to lower the risk of diseases such as diabetes, heart issues and some cancers.

To give an example if you are female aged 20-29 with a VO2 Max at the lower end of the good scale of 33.0 ml/kg/min. Assuming you are not at your genetic maximum you can expect to train it to get at the low end of excellent 37.62 ml/kg/min with a 14% increase, or whatever your genetics will allow.

Should I ignore my VO2 Max?

Completely ignoring your VO2 Max will not be detrimental to your training in any way, especially for the average runner. If you follow a training plan designed to help you reach your goals, your overall VO2 Max will take care of itself. We have all felt the benefits of becoming fitter and stronger with exercise. Based on that and the fact it can only be trained to a certain genetic level, chasing higher VO2 Max numbers may actually be distracting you from what’s important, which is being as prepared as you can be for whatever you are training for. Much of running after all is a mental game. For pro athletes looking for marginal gains, hitting the measured upper limits of their VO2 Max will be critical.

Therefore for most of us, there is no harm in ignoring VO2 Max altogether. If you train consistently, it will improve over time and there is little benefit in chasing numbers you simply may not be able to reach. However, on the flip side, monitoring it to check for progress also does no harm, as long as you do not become obsessed over the actual number.

How training helped my fitness and VO2 max over a year of running

Simply, what does our running do to our VO2 max capacity? I am a sample of one, so this is only a guideline and at the time the test was conducted during half marathon training in 2020. I record all of my runs via an Apple Watch Series 5. I have tested it back to back with a Polar heart rate monitor and am happy that over a long period, the data it gives me can be used to monitor progress effectively in a number of different metrics. My percentile on the VO2 Max Chart being one metric I use.

This is not to say the VO2 Max number is necessarily 100% accurate. However, as long as the data is consistent within itself, i.e. it is recorded in a manner where the data doesn’t have large differences in the collection from each session, it can provide me with a longer-term trend in relation to the effect of running on my VO2 Max capacity and therefore maximal oxygen uptake and general fitness. You can also get an estimation of your VO2 max if you calculate it. To get a completely accurate number you would need to complete a VO2 Max test which needs to be undertaken at a specialist lab with the correct equipment.

Effect of running on VO2 Max
My VO2 Max Chart for 2020

The image above is my VO2 Max as measured by my watch for 2020. As you can see there is a significant uptrend and this puts me comfortably in the excellent category for my age and gender on the VO2 Max chart, assuming the number produced by my watch isn’t ‘too’ far out.

I have never had a VO2 Max test however, so the numbers may be slightly arbitrary. But when I consider my activity levels with my peers, this ‘feels’ about right.

At the start of 2020, I began a half marathon training plan and after running the 21km distance for the first time, I maintained that level of running for the remainder of the year. I completed the last few weeks of the training plan over and over, periodically adding in a longer effort, keeping myself ‘half marathon fit’ so to speak. For 2021, I upped my game and started an Ultra training plan, completing my first 50K in October 2021. This has seen my weekly volume rise significantly and general level of fitness improve, at least on the RPE scale. My resting and running heart rates dropped and my VO2 Max increased by a few more percent. Meaning I likely hit my genetic peak for my age.

In addition to the running I also complete regular strength training. Sometimes this is body weight and sometimes with weights. I focus on my core and lower body to help me become a stronger runner, chasing the elusive injury free experience.

In 2020, training gave me a 13% increase in VO2 Max.

The question is, what is the effect of running on my fitness and why did I see a 13% increase of my oxygen uptake norms during 2020?. In 2021, even with the increased load only saw an additional 5%. Is it purely training volume or do other factors come into play?

In simple terms when we exercise our muscles require more oxygen to function. We breathe air into the lungs, we breathe out the waste products and the oxygen is transported via the bloodstream to where it is needed. During exercise, this is the skeletal muscles we use for our movement. A regular training programme, such as marathon training increases the efficiency of this process and therefore physical fitness.

In my case over the period of two years I have increased that ability by 18% as measured by the VO2 Max data from my watch.

I will normally run 70-80% of my workouts at the famous conversational pace. I do not concentrate on heart rate training, although I do check the zones I have been in, mainly for interest in relation to rate of perceived exertion. This conversational pace would be nice and easy running at ‘can go all day’ pace.

In a 1997 study conducted by A. Berbalk it showed a strong relationship between training volume and heart volume. That is to say low intensity but high volume training has a large effect of the volume of blood the heart can pump.

In my case, my training volume isn’t high compared to many. Between running, cross training, which is mainly cycling, and strength training I exercise 6 days a week, with just one day of inactivity. This is high compared to 2019-2020, where it was more likely 3-4 days running and one or two strength sessions, with no other cross training.

Running is an endurance sport. For me the effect of running on my VO2 Max Chart percentile has been significant. I can feel the difference when I am out. I feel stronger, can run further and what was my 10k pace is now my pace for the half. My current 5k pace is a sprint compared to a year ago. 

I do not measure an easy effort. I use RPE (Rate of perceived exertion) to gauge an easy effort. Based on this, my heart rate when running at an easy effort has reduced by 14%. Maybe this is unsurprising when an Apple Watch uses heart rate data for determining VO2 Max.

Whatever the accuracy of the figure provided by your watch, the effect of running on your VO2 Max score can be a large one. My experience is that a regular training programme to include mainly slow runs and strength training will see runners gradually become fitter and stronger, will increase your endurance, speed and all-round physical well being.
