As a professional trainer, having the ability to measure vo2max is very useful, thus, I have decided to write on the best fitness tracker with Vo2 Max.

Today the world is being ruled by technology. The daily invention of new gadgets is mesmerizing. So much that it has taken over the health and fitness industry too.

VO2 Max

Many modern health apps and gadgets are assisting us to maintain health records. Today we can measure our blood sugar, blood pressure, heart rate, pulse, body temperature all using electronic gadgets.

For many years these measurements have been considered to be important or as they are called “vital signs” of a healthy body.

However, nowadays there is an emerging trend of recording your VO2 Max. Wondering what is VO2max and how can you record it? Let’s get to know about it below.

Here is an article on my website that you must read, its about the Best Fitness Trackers with a Chest Strap And Why Do You Need It?

What Is VO2 Max?

VO2max is a measure of cardiorespiratory rate. Also known as aerobic respiration rate, it is a measure of the rate of oxygen taken in by the lungs and delivered to the bloodstream during exercise. Its normal value is 35 to 40 mL/kg/min.

The main idea beyond a VO2 Max test is to check how fit you are. The declining capacity for oxygen transport is alarming. Thus, it can not only tell the current health status but also predict future risks.

As I myself experienced, in labs measuring VO2max is a difficult process. The patient has to go through some cumbersome tasks like an exhausting 12 minutes of treadmill or other heavy exercises using an oxygen mask. I would prefer wearing a gadget and doing my routine exercise while it measures all the needed information. Let’s have a look at some amazing gadgets that will do this job for you.

How Do Fitness Trackers Track VO2 Max?

The modern wearable fitness trackers are tracking Vo2 Max by using an algorithm that uses a formula that includes data such as your resting heart rate, age, sex, weight, and other personal information.

The Vo2 Max test done by the trackers is different for each brand however, in general, it will require a 10 to 20 minutes run or walk outdoors while using a built-in or connected GPS.

All the fitness trackers are giving an estimation of your Vo2 Max level based on the data that you provide and that is being collected.

You can read more on VO2 Max Estimate here at the Garmin support center.

How Accurate Is The Vo2 Max Tracking Done By The Fitness Trackers Is And Which Brand Is The Most Accurate?

First of all, using a chest strap will always give more accurate HR data than a wrist-based HR monitor – better HR tracking means better and more accurate VO2 Max reading.

As for the Vo2 Max accuracy of the modern fitness trackers. I have read some research and comparisons done by different groups and my main conclusion is that all the fitness trackers will not give 100 percent accuracy. And it varies from one individual to another.

In fact, you should expect a deviation of 5 points up or down. Some researches showed Garmin as the most accurate, others Apple and some Fitbit and it will be hard to determine which brand is more accurate. My personal preference brand when it comes to a sports watch that measures Vo2 Max would be Garmin.
