Runners World US?

Runners World US VO2 max at the moment, then we wouldn’t be surprised. That’s because there are some real benefits to knowing this metric – which is, essentially, a measure of your cardiovascular fitness – and doing a test in a lab is often seen as the most precise way to pinpoint your current VO2 max score.

‘I think [VO2 max testing] is becoming increasingly popular because running as a whole is getting increasingly popular,’ says Greg Laraia, a running coach at Motiv in New York City. In particular, Laraia cites former athletes who are now taking up running and perhaps using VO2 max tests as a way to explore their speed, efficiency and overall fitness.

That said, while VO2 max tests in a lab lead the way when it comes to accuracy, not all runners need to (or should!) do one. So, before you jump on the bandwagon, read on to find out who can – and who may not – benefit from the results of a VO2 max test.

Experts agree that every runner should, at minimum, know what VO2 max is and what it represents. Physiologically, VO2 max is a measure of how efficiently your body takes oxygen and converts it into energy for your muscles to use.

Who should do a VO2 max test in a lab endurance – but it’s more nuanced than that. Why? Because your VO2 max is based on multiple factors, some of which are modifiable and some of which aren’t.

‘Some of it is purely genetic and based on your muscle make-up, what type of muscle fibres you have, the capacity of your lung volume and how efficiently the airways in your lungs can absorb oxygen,’ says James Robinson, a sports medicine physician based in New York City, who also notes age and gender as factors that affect your VO2 max. ‘But other aspects can be modified with training.’

VO2 max tests conducted in a lab – which often have you run on a treadmill at an increasingly harder effort while wearing a mask to gauge your oxygen use – are the most clear-cut way to learn your VO2 max. However, many wearables from Garmin, Apple and more can still give you a solid measure of your VO2 max based on sensor data. While experts say that the accuracy of such wearables varies, this data is probably sufficient if you’re looking to track your VO2 max trend over time.

According to the experts that we consulted, you should only get a VO2 max test in a lab if you know how you’re going to use the information that you get.

For example, if you’re Everything you need to know about recovery runs – and likely have a lot of room for VO2 max improvement – it could be useful to do a VO2 max test in a lab so you have a very accurate benchmark. ‘It gives you a number to say, “Okay, this is where I’m starting from”,’ says Ben Delaney, Most recreational runners probably dont need to do a VO2 max test in the lab. As mentioned, most.

Plus, since there are now established averages for VO2 max based on age and gender, knowing your own, current VO2 max score can help you to see how your cardiovascular fitness compares with others’.

A VO2 max test in a lab can also be handy for advanced runners – especially sprinters – who can use the resultant data for their training. This is particularly true for speed sessions, for example, where runners complete intervals at 80% of their VO2 max. ‘Knowing your VO2 max is useful so you know where to train at the highest intensity to improve your overall cardiovascular fitness,’ says Robinson.

One caveat here is that top-tier runners are more likely to be at their ceiling already, with little room left for VO2 max improvement. So, for some, this may be discouraging. ‘There is a plateau with your anaerobic capacity [and] you can keep working till the cows come home,’ says Delaney, who points out that your body, eventually, will not be able to reach the next level.

Meanwhile, if you just love data and having fun with running-related numbers, then VO2 max tests in a lab probably present little real risk (other than to your wallet – these tests do come at a price). Plus, if you have a wearable, you can compare the data to see how accurate it really is.

If you do decide to head down the lab test route, Laraia suggests doing one every six months so you have enough time to make some progress in between each test. Even better, he recommends aligning your VO2 max tests with races. For example, you could get a lab test before you start training for a 5K or a 10K, then retest either right before or right after your race. ‘The cool thing about that is you’ll have a new baseline in terms of intensity for your next training cycle,’ says Laraia.

Most recreational runners probably don’t need to do a VO2 max test in the lab. As mentioned, most wearables If youre currently training for a long distance event like a.

What’s more, runners who are hyper-competitive might find the lab data more harmful than beneficial. ‘Some people are a little too competitive and can get too fixated on these numbers,’ says Robinson.

Laraia, too, cautions against comparing your score with other people’s, since VO2 max is so multifaceted and unique to the individual. Besides, it won’t confirm whether or not you’ll be faster than them in a race. Laraia, for instance, once conducted a VO2 max test on an underwater welder with no running experience. While the underwater welder obtained an extremely high VO2 max score due to the physical nature of his day job, he probably wouldn’t do so well in a 5K race What is VO2 max and how do you test it.

If you’re currently training for a long distance event like a marathon, you may also want to skip or at least hold out on a VO2 max test. That’s because the type of workout required to most effectively increase your VO2 max is high-intensity interval training (HIIT) – and, according to Robinson, overdoing it at any time, especially during a marathon training block, can lead to overtraining and injury. More specifically, HIIT can put undue stress on your tendons, bones and ligaments, especially if you are already doing a lot of mileage in the week.

In this case, Robinson says that ‘trying to focus on improving your VO2 max can actually be detrimental to your overall goals’ – and training to improve your VO2 max is best done when you don’t have a distance race on the calendar. ‘I think you should be focusing on just getting your body used to that type of mileage.’

In addition, Laraia says that you might want to skip a VO2 max test in the lab if you tend to get overwhelmed by data and numbers. Sometimes, knowing too much about your fitness levels complicates training, when all you really need to do is follow a solid training plan Running pace conversion chart easy runs.

Finally, it’s worth noting that you don’t need to do a VO2 max test if it’s not in your budget. ‘Some of this testing can be expensive, so it may not be financially feasible for everybody to do it,’ says Robinson. ‘I don’t think that it’s necessarily something runners have to know.’

Laraia, for his part, says that it might ‘cool to see’ the results of a VO2 max test. However, he still feels that he gets enough data from his running watch and a running coach at to help him assess his progress.

Before you sign up for a lab visit, you might want to consider a couple of alternatives to VO2 max testing.

The first is a simple gait analysis. ‘Let’s say you’ve had a lot of running-related injuries – in this case, a running analysis is probably more useful [than a VO2 max test] to find some abnormalities in your gait that have made you more prone to injury,’ says Robinson.

The second is a metabolic profile test, which encompasses VO2 max. This can benefit those who are looking to achieve a specific race time, or who want to run faster more generally. Robinson, in particular, says that knowing your lactate threshold (another part of the metabolic profile test) is probably more important in the long run if these are your goals.

Other metrics that the experts say can help to identify improvements in your cardiovascular fitness include your running pace, your rate of perceived exertion during runs and your weekly mileage. If you’re increasing your weekly mileage, you’ll be building your aerobic capacity.

Finally, Laraia says that keeping tabs on your How far is 10,000 steps For example, if youre.
