What’s VO2 max and why is it vital?

VO2 max is the utmost quantity of oxygen your physique can make the most of throughout train. At your highest depth, it’s the amount of oxygen your physique is utilizing. It’s usually measured in milliliters of oxygen per kilo of body weight, per minute of train. It usually ranges from the 20s to 60s.

There are two primary explanation why figuring out your VO2 max is so vital. One is as a measure of health, notably for endurance athletes, though anybody who has a cardiovascular component to their coaching will profit from the insights the check offers.

The opposite component is well being. VO2 max is taken into account among the best predictors of longevity. We measure a number of issues at HAWQ Rating and we wish to put all the things collectively as an even bigger image. But when I needed to decide one quantity, VO2 max is probably the most useful indicator of long-term well being.

So it’s vital for everybody and key to endurance sports activities?

For marathon runners, cyclists and anybody who enjoys endurance sports activities, your VO2 max will be an vital predictor of your efficiency, as a result of it’s your cardio capability. Different elements together with your working financial system and your effectivity are vital too. 

However for those who’re a soccer participant, or a rugby participant like I’m, it’s notably vital to have an endurance base. You may need to dash after a ball now and again, however having a superb VO2 max goes to provide the capability to maintain going for a very long time.

How do you measure VO2 max?

The gold commonplace is a VO2 max check, which will be achieved both in a science lab or in a gymnasium that has specialist expertise. Right here, we use one thing known as the VO2 Grasp. It’s a face masks with a gasoline analyzer that instantly measures gasoline consumption. It takes a pattern of the air round you and what you breathe out. From there it really works out how a lot oxygen is used and the way a lot CO2 you produce. This could present a direct measurement of your oxygen consumption.

A VO2 max check is a ramp check carried out on a treadmill or a stationary bike that often takes round 15 to twenty minutes.You begin slowly and get faster till you’ll be able to’t go any additional and attain your most effort. It’s a maximal-effort cardio check.

Alternatively, sports activities watches can estimate your VO2 max. Nonetheless, they’ll’t truly measure your oxygen consumption, so it’s an estimation. That stated, some watches are fairly correct and a superb indicator of your health.

How do sports activities watches estimate VO2 max?

There are two methods to estimate your VO2 max utilizing a sports activities watch, and plenty of manufacturers mix each. The commonest methodology is utilizing your coronary heart charge. Some will estimate your VO2 max out of your resting heart rate, which might be one of many much less correct methods to do it. Different watches use your most coronary heart charge in contrast along with your coronary heart charge throughout train. From that it’s going to use algorithms to assist predict your rating based mostly on individuals who have achieved gold-standard VO2 max assessments.

Quite a lot of watches go one step additional, and observe your velocity, distance and coronary heart charge throughout train. This collates as a lot info as attainable to make that estimation extra correct. So far as I’m conscious, that’s the 2 methods watches at present do it, nevertheless it’s an enormous subject and all the time evolving. 

Are you able to enhance the accuracy of watch estimates?

I might advocate getting a chest strap that connects to your watch to extend the accuracy of your coronary heart charge knowledge. If you happen to ever do a full VO2 max check and get your heart rate training zones, you’ll be able to truly enter that knowledge into numerous watches. That makes it extra correct as a result of the watch is aware of 140bpm is in your zone 2, and for those who’re now working quicker on the similar coronary heart charge, you’re getting fitter. It’ll provide you with a dynamic estimate of your VO2 max based mostly on earlier predictions.

One other method that utilizing a chest strap will be useful is for those who do a self-guided VO2 max effort check. That method your watch can decide up a brand new, correct max coronary heart charge. Everyone seems to be so completely different—220 beats minus your age [the way most watches estimate your max heart rate] is an efficient indicator, nevertheless it’s a mathematical estimation, not a scientific measurement.

Are you able to estimate your VO2 max based mostly in your race instances?

Typically, the quicker you might be throughout a race, the higher your VO2 max goes to be. That stated, notably with working, your effectivity, kind, financial system, how recovered you might be on the day, plus your hydration ranges and vitamin technique will all have an effect on your race instances. 

Paula Radcliffe’s VO2 max didn’t change over a few years of coaching. And but she went from not profitable to setting a brand new marathon world document as a result of she was extra environment friendly and her kind improved. 

Race instances are usually a superb estimate and for those who’re working quicker, you’re in all probability going to have the next VO2 max than somebody who’s slower than you. Nonetheless, with out truly doing a VO2 max check to measure it you’ll be able to’t be 100% sure.

How do you enhance your VO2 max?

To enhance your VO2 max, the 2 most vital exercises I like to recommend are lengthy, gradual regular runs and interval training. After I say gradual, I imply gradual. A zone 2 exercise, in your endurance zone, will enhance cardio capability. It ought to be for at least half an hour, the longer the higher.

The way in which to estimate your zone 2 is to coach with somebody. If you happen to can discuss you’re on the proper tempo, since you’re respiratory on the proper frequency and never working too arduous. It is advisable enhance your coronary heart charge somewhat bit with out pushing it too far. There are very particular variations you get by doing a zone 2 exercise however for those who go too quick, you’re not going to profit.

On the different finish of the spectrum, I like to recommend zone 5 intervals. Run arduous at your most effort, till you’re actually out of breath. You need to work arduous, however you additionally need to get better nicely. Intention to be within the high 10% of your max coronary heart charge, and spend 30 to 60 seconds in that coronary heart charge zone. Don’t simply run 30 seconds all-out—take a minute to get your coronary heart charge up there. As soon as it will get above 90% of your max coronary heart charge, then the following 30-second interval begins. Intention to get better totally so you’ll be able to go all-out on the following one. 

How typically do you have to do VO2 max assessments to see for those who’ve improved?

Until you’re a newbie who plans to abruptly begin coaching actually arduous, I might advocate doing a VO2 max check each 6-12 months. Within the meantime, you’ll be able to observe your coronary heart charge throughout exercises. If you happen to do the identical exercise at a decrease coronary heart charge or you’ll be able to hold the identical coronary heart charge whereas going additional then this could be a good indicator that you simply’re enhancing your VO2 max with out essentially having to do one other check.
