Polar M200 Accuracy Tests

Introduction

With the rapid emergence of wrist based heart rate technology I have nominated myself to the role of checking their accuracy. To date I have completed tests on the accuracy of the strapless HR acquired by the TomTom Spark 3, Garmin Vivoactive HR and Garmin Vivosmart HR. Each tests involves comparing the heart rate trace acquired directly from the wrist to that acquired using the traditional chest strap style sensor.

Objective

The objective of this test was to determine the accuracy of the heart rate acquired by the LED sensors on the back of the Polar M200 compared to the HR data acquired using a gold standard control. In this instance the control model is a Polar M450 paired to a Polar H7 Bluetooth chest strap style sensor.

Test Equipment Used

Test Rides

I decided to perform the tests on my bike. The wrist based HR sensors suffer most when used on a bike due to the vibration through the handlebars. I consider this ride to be a WORSE CASE scenario as the road surface on the A149 is far from smooth. The full ride data can be found here for the M200 and here for the M450.

Results

I have overlaid the heart rate graph from the M200 on top of the M450’s. Remember, the M200 is wrist based, the M450 HR data comes from a chest strap.

Conclusion

I have now used the M200 six times for everything from a 23 mile bike ride to a 5 mile run, gym session and turbo train workout. My conclusion from these tests is that the Polar M200’s wrist based HR system is BRILLIANT. Somewhere in the region of 98% accurate compared to a chest strap HR sensor. If you want the convenience of strapless heart rate monitoring and a GPS for accurate speed & distance then I highly recommend the Polar M200.

Supporting Data from Test 1

The images below show the data extracted from the M450 and M200 displayed on the Polar Flow website. As you can see the average HR of the two devices is 137bpm and 138bpm, in other words almost identical. The calorie burn is 931 kcal versus 939 kcalof the M200, again, almost identical. The Time in Zone data is also very similar.

A Brief History…

It all started in 1996. As a sports science student I wanted to promote the use of Heart Rate Monitors in exercise. The business went online in 1999. In 14 years we sold HRM's to over 300,000 customers.

After a short retail back we're now back with the new online store selling ONLY Polar. We still offer impartial advice & test other heart rate monitor brands. Our aim however, is to introduce you to Polar's products as an alternative to Garmin, Fitbit, Suunto or TomTom.
