The researchers evaluated seven fitness-tracking devices with the help of a small group of 60 volunteers and found that six of the devices were accurate for heart rate to within 5 percent. And as Stanford researchers reported in a May 2017 issue of the ​ Journal of Personalized Medicine​, even good accuracy from a heart rate monitor doesn't always correlate to accurate calorie-burn estimates. Here, it's that measuring your exercise intensity (in this case, according to heart rate) is just one of many factors that goes into estimating how many calories you've burned.
What About the Accuracy of Calories Burned? Two of the best ways to be sure you're getting a clinically validated Polar heart rate monitor — which is especially important if you're wearing a heart rate monitor for medical reasons, but also guarantees better accuracy if you're tracking your heart rate to measure exercise intensity — are to talk to your doctor or to search the PubMed database for clinical trials validating your particular model of Polar heart rate monitor. Many of these models have been clinically validated for their accuracy, to the point that they're often used as the baseline for monitoring heart rate activity in clinical studies. If you're looking for a wearable heart rate tracker that's readily available to consumers, you can hardly do better than a chest-strap heart rate monitor from Polar.
