How Accurate Is Your Running Watch's Heart Rate Monitor?

Have you ever wonders how accurate your watch's heart rate monitor is? I did, so I decided to test it against a chest HRM and found the results very interesting, and I think you will too!

Looking 4 watch vs chest strap.. found ur video great information!

Thank you. I've used a heart rate monitor since I met Dr. Maffetone in 1987. These days, I"m much slower at 65, but still concerned about training in the zone. Watch or strap? This video was helpful and I appreciate it. Train smart and have fun!

Which app or website are you using in this demonstration

Please correct me if I am wrong but it seems to me that you have forgotten to set the same heart rate zones on both watches. The zones are not changed by peaks. They needs to be set in the options of your device, or not? (Go to the web app, click on your watch in the top right corner, set the zones there somewhere).

726 vs 689 is a 3-4% which is nothing on a recreational, not medical, device.

They're not inaccurate, they're within the tolerance expected

Lower the music. Or just get rid of it.

If you connect the chest strap with the clock, it is automaticaly using the heart rate from the chest strap an deactivate the heart rate measurement on the clock-optipal on the wrist?

[DamirUlovec]

Sir, I have reason to believe that your heart rate zones are set too low. There's no way that someone can sustain over 20 minutes in Zone 5. Exceptions are very top elite individuals, but even they will struggle to stay in red zone for over 20 minutes. You should do a Rockport walk test or (if you feel fit enough), try Cooper test. One of those will give you the "real world" of your heart rate training zones (Z1, Z2, Z3, Z4, Z5).
I was always suspecting that wrist HR monitors aren't precise enough, thank you for clarifying that. Great video.

Appreciate the content but the background music is loudand distracting

[cpatrader]

So, which one do you think is more accurate?

[jamesrodrigue]

Good video. Turn the freaking music down.

[communicationiskey-]

Can barely hear you with background music…

[johnnytorres]

The background soundtrack is distracting. Can't understand some segments. Suggest not using a soundtrack at all.

[videoforum]

Too loud music. Music isnt even necessary

[josephtucciarone]

Not all individuals will have the same level of difference. You assume the chest monitor is exact. Maybe the truth is in-between the two readings.
