RHR, HRmax, SpO2, HRV, VO2 max—can the cardiovascular alphabet soup get any thicker?! There are seemingly countless metrics to trace and (useful although they might be), all these acronyms and numbers can get complicated and overwhelming, too.
One fashionable health metric is VO2 max, which, in easiest phrases, is a measure of cardiovascular health (how effectively your coronary heart, lungs, and blood vessels work throughout train). To interrupt down what that every one means, I related with scientific train physiologist and licensed energy and conditioning specialist Alexander Rothstein. Right here’s what you’ve acquired to know.
Key Takeaways
- VO2 max is an indicator of cardiorespiratory health.
- It’s a measure of oxygen consumption; particularly, the utmost quantity of oxygen your physique can consumption and make the most of throughout train.
- VO2 max can be utilized as a predictor of race/occasion efficiency for a number of sorts of athletes.
- It’s finest measured in a lab, however there are methods you may estimate it at residence, corresponding to with the Cooper train check.
- It’s regular for VO2 max to say no with age, and it will get tougher (however not unimaginable) to enhance it as you become old.
- Intercourse assigned at beginning and corresponding hormone ranges, in addition to physique dimension and composition, additionally play a task in VO2 max.
- Enhancing VO2 max worth requires coaching at very excessive intensities, typically reaching and surpassing your lactate threshold and getting near your most coronary heart fee.
- Excessive VO2 max is just not related simply with bodily health, but in addition well being: It’s related to a diminished threat of heart problems.
What Is VO2 Max?
VO2 max refers to maximal oxygen consumption, measured in quantity.
“VO2 max represents our physique’s physiological capability to consumption oxygen, ship it to working cells, and use it on the mobile stage to provide adenosine triphosphate (ATP), the power forex of the physique,” Rothstein tells BarBend.
“It isn’t a direct measure of respiratory operate or cardiac operate, however as a substitute represents the interplay between many physique methods with a view to produce power as quickly and effectively as potential when the physique is in want (when performing massive quantities of motion corresponding to high-intensity train),” he explains.

The amount of oxygen you may devour is represented in milliliters of oxygen consumed per kilogram of physique weight per minute (mL/kg/min).
In different phrases, it’s a great indicator of maximal cardio capability, and discovering it offers you an image of your baseline cardio health. “We will use VO2max values as a consultant of cardiovascular well being and it could possibly assist determine potential cardiorespiratory considerations and limitations people could have,” Rothstein says. “For people who’re both high-performance athletes, or prepare recreationally and need to maximize their exercise program, a VO2 max check may also help do this.”
With that stated, Rothstein says that VO2 max is a nice-to-have metric and not required. Most people can use submaximal testing and a few non-exercise equations to estimate their VO2max, he says, which might suffice for many leisure athletes and health lovers.
VO2 Max Chart
Typical, wholesome VO2 max scores range with age, intercourse, physique dimension, physique composition, and coaching historical past. The next are common values by age and intercourse assigned at beginning (we want extra analysis on nonbinary and trans individuals) offered by the American School of Sports activities Medication (ACSM). All values are reflective of mL/kg/min. (1)

Information was not collected as as to whether trans males had been included in these statistics. Extra knowledge can be wanted for nonbinary individuals.
“Most of the parts that make up VO2max are impacted by physique dimension, and due to this it’s common that males could have greater values than girls,” Rothstein says. Nonetheless, that isn’t essentially consultant of upper efficiency, as a result of a bigger physique can even require extra ATP.
“That is partially accounted for in that relative VO2max values embrace a measure of physique mass,” Rothstein explains, “though they don’t alter for lung and coronary heart dimension or blood quantity, which all are usually smaller in girls, reducing their VO2 values.”
VO2 Max by Age
It’s regular for VO2 max to lower as we age, Rothstein says, and the normative knowledge displays that. “Additionally it is tougher to enhance as we become old, however it’s not unimaginable,” Rothstein factors out, including that “it’s by no means too late to enhance cardiorespiratory well being and performance.”
- In keeping with some analysis, VO2 max drops off considerably round center age when evaluating 41–50 and 50+ age group knowledge to after age 41 to 21–30 and 31–40 age teams. (2)
- VO2 max is usually stated to lower by 10 % every decade, however newer analysis means that determine could also be oversimplified. Nonetheless, it stays true that it’s tougher to enhance VO2 max later in life. (3)(4)
How To Measure VO2 Max
The gold customary is lab testing.
VO2 max is measured utilizing a metabolic cart that concurrently measures coronary heart fee (cardiac output) and impressed and expired air (how a lot oxygen you breathe in and the way a lot carbon dioxide you breathe out). These checks are additionally known as cardio-pulmonary train checks (CPET) and are essentially the most correct approach to measure VO2 max, in line with Rothstein.

Alternatively, as a result of lab testing isn’t available to everybody, you are able to do a discipline check. This methodology entails utilizing a submaximal protocol, which may use workload and coronary heart fee to estimate VO2 max. You’ll put on a coronary heart fee monitor and use a stopwatch to do that. Some checks, just like the INSCYD operating protocol, additionally use GPS knowledge for higher accuracy.
There are dozens of how to do that, from outside run checks to treadmill checks to strolling checks. You may even discover sport-specific protocols. A bike owner, for instance, would get extra worth from a motorcycle VO2 max check than a run check on a monitor. One instance for runners is the Bruce Protocol check.
How To Enhance VO2 Max
Enhancing VO2 max requires high-intensity efforts in coaching. It typically seems like what chances are you’ll know as high-intensity interval coaching (HIIT).
“An important consideration when making an attempt to enhance VO2max is that for any intercourse, age, or athlete, the coaching depth must be excessive sufficient to stimulate the physique to adapt,” Rothstein says. “If the coaching stimulus is just not massive sufficient to sign the necessity to use sources to enhance oxygen-consuming capability, then the physique is not going to adapt and maximal oxygen uptake is not going to enhance.”
One other vital word, Rothstein says, is that learners will expertise a rise in VO2 max in a short time: generally as shortly as inside every week, as their cardiovascular system quickly turns into extra environment friendly and their blood plasma will increase.

For extra elite athletes, nonetheless, diversifications can take years, and it requires constant coaching of adequate depth to sign the physique that there must be an enchancment in oxygen supply and utilization.
VO2 max exercises contain brief bursts of high-effort train. An instance for operating seems like:
- 1-mile straightforward dynamic warm-up
- 8x400m at 90% of HRmax
- 3-minute relaxation or stroll interval between units
- 10-minute straightforward cool-down
Different sorts of coaching work as nicely, Rothstein says, “however the secret is that the person is coaching at a excessive sufficient depth to sign the necessity for enchancment.”
Totally cardio train, like low-intensity, lengthy jogs is not going to essentially assist enhance VO2 max as a result of you aren’t signaling the physique that you just want extra ATP shortly—simply that you just want the identical quantity of ATP for an extended time period.
“When jogging, you’re performing lengthy, steady-state train, so as soon as the physique has sufficiently reached the extent to try this, it is not going to essentially enhance additional [without high-intensity efforts],” Rothstein says.
Steadily Requested Questions

How do I enhance my VO2 max?
Enhancing VO2max is a matter of applicable coaching and time, says train physiologist Alex Rothstein. Excessive-intensity coaching works finest usually, he says, as a result of “the physique is being instructed that it must get higher at utilizing oxygen for power manufacturing as a result of there must be numerous ATP shortly.”
How can I do a VO2 max check on a treadmill?
Step one is to determine which check protocol you need to run. There are lots of to select from, such because the Bruce Protocol and the Cooper Take a look at. Subsequent, collect any gear or gadgets you want, corresponding to a coronary heart fee monitor or stopwatch. Observe the protocol in line with the directions and calculate your outcome utilizing the offered method.
How do I calculate my VO2 max with resting coronary heart fee?
Whereas there’s an equation used to calculate VO2 max utilizing resting coronary heart fee, it’s removed from essentially the most correct approach to do it. An individual’s resting coronary heart fee is essentially decided by genetics, and plenty of elements apart from coronary heart fee play a task in a single’s VO2 max. A discipline check, treadmill check, or lab check is a greater approach to discover your VO2 max. The equation, if you wish to use it, is: VO2 max = 15.3 x (HRmax/HRrest).
