Research: Wearable items, including Apple Watch, are low in calorie tracking

In a paper published in January this year, researchers are trying to evaluate the usefulness of smart devices worn on the wrist to monitor energy consumption and heart rate. Apple Watch Series 6, Polar Vantage V and Fitbit Sense were used by 30 healthy participants, men and women, who engage in weight training, cycling, running, walking and even sitting. As reference devices, the team used the Polar H10 and MetaMax 3B chest strap.

Now, we will not bore you with the details of the study or the methods used, because we find them quite solid and, instead, we will talk about the findings. The boys from Stronger than science summarize it in a simple table that evaluates the accuracy, variability, and reliability of each device.

As it turns out, all the devices were pretty bad at tracking calories in almost every activity. Not only that, but the average deviation from actual daily expenses was unpredictable and variable, making the clocks unnecessary to track calories. That’s because you can’t reliably track progress even if absolute values ​​are off. It seems that laptops are even more inconsistent with people who have lower than average energy costs and higher than average.

Also, the research seems to be consistent with previous ones trying to assess the same capabilities, but with different devices worn on the wrist.

The good news is that the Apple Watch Series 6 has been quite reliable in tracking your heart rate in all activities. Polar Vantage V and Fitbit Sense laptops fluctuate with exercise. The number of steps also seems to be suitable for all devices involved in research.

Bottom line? Despite its limitations, such as the small sample size of devices and people, research seems to be consistent with previous ones, suggesting that commercially available smart watches and wrist fitness trackers do not provide reliable measurements of daily energy consumption. . In addition, they are very unpredictable.

However, heart rate tracking and step counting are features that are usually quite useful and reliable. In fact, some research suggests that smart devices can have a positive impact on physical life. People who use smart portable devices tend to increase their overall activity and number of steps.
