Additional Steps After Pairing Polar H10 Chest Strap to Garmin Forerunner 45s?

Christina

Hey everyone!

      Does anyone know if there are additional steps needed when you're starting a workout after you successfully pair an H10 to your watch? The strap paired easily and when I started the workout on my watch it said External HR Sensor on the watch and beeped, which seems correct. I didn't pair the strap to my phone so it would only run through the watch. The reason I'm asking is the calorie burn is VERY different than what I saw when I used the strap and ran the exact same workout pairing with my phone through Polar Beat. Thanks!

    For the Calorie burn to work correctly, the HRM must send HR Variability data to Garmin, so I'd verify first whether your HRM belt is compatible with the HR Variability feature.

    I’m not exactly sure what that means? I know the Garmin pairs with ANT+ devices, which the H10 is.

    You'll find the answer in the Support document What is Heart-Rate Variability (HRV) ?

    Both devices seem to appropriately use HRV data. Whether it transfers through ANT+ to Garmin...I don’t know how to be able to identify that.

    I checked uo the technical specifications if H10, including the user manual of H10, Polar's own wbesite, and looked up diverse other sources, but found nowhere that the H10 would support the HR Variability. Where exactly do you see it does?

    The Polar H10 is listed on here.

    Whether the HRV data from the Polar H10 chest strap transmits through ANT+ to the Garmin, that’s what I can’t find and essentially why I posted on the forum. I just didn’t know the technical term around it. 

    There’s a possibility that maybe the watch is more accurate for calorie burn than the chest strap also. I just did the same two recovery workout twice and got about 100kcal difference per workout between the chest strap running through Polar Beat and the chest strap through the Garmin watch.

    Doing the same workout twice does not mean you burn the same amount of energy. The effort may be each time diametrically different. And the Calories calculated depend also on the average Resting HR for the current day, so if you do not wear a HRM round-the-clock (including the sleep hours), then the average Resting HR may differ considerably between idividual days.

    Totally understand all of that. However, I do wear the watch around the clock and I chose to do two recovery workouts (yoga) because my burns analyzed by the Polar H10 are always extremely similar. They have been for years. My resting heart rate has also remained consistent for a long time as well. I’ve been monitoring via Polar H10 for a long time so I know my numbers through that device. It just seems odd that using that device through the watch is decently different. I was just curious if I was missing a step or if the watch that I chose doesn’t get all of the data through ANT+.

    If you speak about the difference of the burned Calories reported by the Polar Beat vs. by Garmin Connect, then another reason may be that each of them reports a different value. For example the Calories of an Activity reported by GC contain also the RMR (resting Calories), which depends on the data entered in your User Profile (gender, age, weight, heigth, Activity Class), and on the duration of the Activity, of course, too. It is a question whether Polar Beat includes the RMR at all, and if yes, then whether it uses identical data (including the Activity Class). And then, even if both apps refer the same data, each of them may be using quite different algorithm. Do not forget, that all this Calories reports are only estimates based on available data, and no scientific measurment, that is possible only in lab conditions, so by principle they can never be really accurate.
