If you\u2019re part of the online running community, you\u2019ve probably seen runners flexing their VO2 max numbers<\/a>. If you wear a running watch, you\u2019ve probably also aware of your own VO2 max\u2014maybe you\u2019ve been proud (some devices equate a higher VO2 max with a lower fitness age!) or maybe you\u2019ve just been confused as to what this number even means. <\/p>\n

VO2 max<\/a> has long been considered one of the gold standards for measuring cardio fitness<\/a>. That said, getting a real measurement has been inaccessible to a lot of runners for just as long, because it usually involves going to some kind of sports performance lab for a test that isn\u2019t cheap. But here\u2019s the good news: You don\u2019t need a lab to estimate your VO2 max. You can get a pretty good sense of where your fitness stands without any fancy tech, right at home. Here\u2019s what to know.<\/p>\n

This biometric has become a fitness buzzword in recent years. It measures, in milliliters of oxygen consumed per kilogram of bodyweight per minute, how much oxygen your body can use during exercise. <\/p>\n

What does that really mean? \u201cIt\u2019s a measurement of the capacity of your cardiovascular and respiratory system while you carry out strenuous exercise,\u201d explains Carson Gantzer, C.S.C.S., a performance physiologist at Human Powered Health<\/a> in Scottsdale, Arizona. \u201cThe more oxygen you\u2019re able to intake, the better all of your systems are functioning and operating.\u201d<\/p>\n

A higher VO2 max<\/a> is associated not just with better fitness, but also improved overall health. In 2016, the American Heart Association issued a statement<\/a> saying that VO2 max should be considered a vital sign, and a meta-analysis<\/a> published in the International Journal of Exercise Science that same year called it \u201cthe strongest predictor of cardiovascular and all-cause mortality.\u201d <\/p>\n

\u201cEssentially, the higher your VO2 max is, the better your healthspan and longer your lifespan,\u201d says Gantzer.<\/p>\n

For runners, VO2 max is a big indicator of your aerobic fitness<\/a>, which plays a huge role in how fast, how long, and how hard you can run. \u201cI like to think about it as the size of your aerobic engine,\u201d says Jonah Rosner<\/a>, a sports scientist focusing on runners. The more efficiently your body can deliver oxygen to your muscles so they can produce energy, the easier it will be to sustain a certain pace. <\/p>\n

Traditional VO2 max tests<\/a> are done on a treadmill in performance labs, physical therapy facilities, medical centers, or even some gyms. The test is a graded one, in that it starts at a low-intensity effort and increases by a fixed amount\u2014by upping the speed of the treadmill<\/a> or increasing the incline\u2014at regular time intervals until exhaustion, usually within eight to twelve minutes, says Rosner. (You\u2019ll do a separate warmup<\/a> before the test.)<\/p>\n

During the test, you wear a mask that\u2019s connected to something called a metabolic cart, a device that \u201cmeasures the amount of oxygen you\u2019re consuming and carbon dioxide you\u2019re producing to indirectly calculate energy expenditure\u2014this process is called indirect calorimetry,\u201d explains Rosner. As your exercise intensity increases, so does your body\u2019s demand for oxygen. \u201cYou reach your VO2 max when the amount of oxygen that you\u2019re using stabilizes, even if you\u2019ve increased the speed<\/a> or intensity<\/a> of the exercise,\u201d he says.<\/p>\n

This kind of test is known as the direct method of determining VO2 max, explains Gantzer, but it\u2019s not always convenient or affordable for runners. That doesn\u2019t mean you can\u2019t get a good estimate of this fitness metric, though. <\/p>\n

There are indirect methods for estimating VO2 max that you can DIY without a mask or a technician or even a treadmill. \u201cThese are considered \u2018indirect\u2019 because there is no direct measurement of any oxygen or gases,\u201d says Gantzer. \u201cInstead, you\u2019re looking at metrics like distance covered or time trial performance.\u201d<\/p>\n

Many fitness watches estimate your VO2 max<\/a> based on heart rate data and exercise data, like pace. <\/p>\n

Related Story3 Ways to Test Your VO2 Max at Home
1. The Cooper Test<\/p>\n

The Cooper Test<\/a> dates back to the late 1960s, and was proven<\/a> to closely correlate with laboratory-determined oxygen-consumption data. <\/p>\n

It\u2019s a super simple field test; all you really need is a stopwatch and, ideally, a 400-meter track (though you can do it anywhere, as long as you\u2019ll be able to easily calculate your total distance). <\/p>\n

After a short warmup<\/a>, run or walk as fast as you can in 12 minutes. Then, you\u2019ll calculate your VO2 max using the formula below. \u201cEssentially, the more distance an individual can cover, the higher your predicted VO2 max will be,\u201d says Rosner.<\/p>\n

Formula:<\/strong> VO2 max = (35.97 x your distance in miles) \u2013 11.29<\/p>\n

2. The Rockport Walk Test<\/p>\n

Another straightforward field test\u2014but with a few more steps and a little more math\u2014the Rockport Walking Test was shown to be a valid predictor of VO2 max compared to a running test in a 2011 study<\/a> published in Military Medicine. <\/p>\n

Similar to the Cooper Test, you\u2019ll do a short warmup<\/a> at an easy walking pace. Then, you\u2019ll walk as fast as you can (no jogging!) for one mile. At the end, record your time in decimals (i.e. 14.5 minutes for 14:30) and record your heart rate<\/a> immediately (you can count your heartbeat for 15 seconds and multiply by 4) or check your smartwatch. You\u2019ll also need to know your weight in pounds. <\/p>\n

Formula:<\/strong> VO2 max = 132.853 – (0.0769 x your weight in pounds) – (0.3877 x your age) + (6.315 x 1 if you are male or 0 if you are female) – (3.2649 x your walking time) – (0.1565 x your heart rate at the end of the test)<\/p>\n

3. Heart Rate Ratio Method<\/p>\n

There\u2019s a very simple equation you can use to calculate your VO2 max, according to research published<\/a> in the early 2000s. But first you\u2019ll need to calculate your resting heart rate<\/a> and your heart rate max<\/a>. <\/p>\n

You should calculate your resting heart rate right after you wake up, by placing your index and middle fingers on your carotid (neck) or radial (wrist) pulse and counting the number of times your heart beats in one minute (you can also count for 30 seconds and multiply that number by two, or 15 seconds and multiply by four). <\/p>\n

There are several options for calculating max heart rate<\/a>, the most simple of which is to subtract your age from 220 (it\u2019s not always accurate, but gives an estimation). Then, you\u2019ll use the below equation to estimate VO2 max.<\/p>\n

Formula<\/strong>: VO2 max = 15 x (max heart rate\/resting heart rate) <\/p>\n

Related StoriesWhat to Do With Your VO2 Max Stats<\/p>\n

Like most trackable biometrics, one of the best reasons for measuring your VO2 max is to monitor your fitness progression<\/a>. \u201cAs you become more aerobically fit, this number will continue to increase, and you\u2019ll see your big block of zone 2 running<\/a> or your Norwegian<\/a> 4x4s are actually helping you to become a healthier and faster runner!\u201d says Gantzer.<\/p>\n

Measuring your VO2 max can also help with determining your training zones<\/a>, says Rosney, including your heart rate zones and anaerobic threshold<\/a>. A wearable can estimate those, but because it uses data that may or may not be accurate (like your heart rate), your zones and recommended paces may be slightly off, which could negatively affect your training\u2014i.e. you\u2019re running your easy efforts too hard, or you\u2019re not pushing the pace enough in your intervals<\/a>.<\/p>\n

That said, there are some caveats with indirect testing, during which you\u2019ll get an estimate of your VO2 max. \u201cIf you choose to measure your VO2 max outside of a lab, at a gym, or on a track, you should take your results with a grain of salt,\u201d says Gantzer. \u201cWhile indirect methods can be more affordable and completed on demand, they present numerous opportunities for skewed results because of poor pacing<\/a>, lack of applicability of a certain test protocol to a certain population, inconsistent heart rate monitoring equipment reliability and validity, and lack of control of testing conditions and environment.\u201d<\/p>\n

Same goes for the estimated VO2 max on your watch<\/a>. \u201cWhile wearables and their algorithms are becoming better at estimating VO2 max values, they still have limitations due to their hardware,\u201d says Gantzer. These devices aren\u2019t always 100 percent accurate, and \u201cif you\u2019re feeding inaccurate information into an algorithm, you\u2019re going to get an inaccurate result,\u201d he adds. <\/p>\n

Bottom line: \u201cI would argue that most runners don\u2019t need lab-based VO2 max testing,\u201d says Rosner. It can be a valuable tool, but the trend is more important than a singular number. \u201cIf you do a workout<\/a> and then train for a few weeks and do the same workout, but it feels easier and you\u2019re going faster, that\u2019s just as valuable information as a specific number.\u201d <\/p>\n

Instead of fixating on any one data point, focus on what matters most: consistent, smart training.<\/p>\n
