Suunto Spartan Sport Really high calories burned

Sorry, don’t know what might be the issue. I don’t usually pay attention to Calories but I checked my last activity and the calorie estimate seems to be reasonable - 475 Cal for a 4.2 mile run with some elevation gain.

@Kyle-Vander-Ploeg-Wright @silentvoyager

Today => 1:15h 13.5k 158HR(avg) -> 1200 calories (should be 900 -1000)

Same route (should be 600-700)
2019/09/13 => 0:52h 9k 158HR(avg) -> 830 cal
2019/08/20 => 0:49h 9k 149HR(avg) -> 694 cal
2019/07/22 => 0:52h 9k 149HR(avg) -> 755 cal
2019/07/17 => 0:47h 9k 158HR(avg) -> 761 cal
2019/06/15 => 0:50h 9k 168HR(avg) -> 917 cal

Perhaps I’m in the same case (not so big difference) and didn’t realize

BTW, weather here in north of Spain is a bit crazy and training in different hours… it’s difficult (for me) to mantain avg HR for same route

475 for 4.2 mile?
I’ve got 689 for 7.5 mile

I just didn’t know if other people were having the same problem. Is Suunto even working on fixing this problem? Or is this just normal and I have to deal with it (I just divide the calories burned in half and that gives me a more reasonable number)

I agree with @zhang965, @silentvoyager those numbers don’t seem right. Like it’s the opposite of what I’m going through. That’s about my average calories burned for a 2-3 mile run, but my watch would show me that I burned 800+ calories for that. That’s really weird.

Hi perhaps this helps.

The workout summary contains the BMR calories.

So for example my bmr is 1700kcal so 1 hour is ~70kcal.

Any workout at any intensity i would do for 1h i would have 70kcal included.

So from the other app data you should remove the BMR

Dimitrios Kanellopoulos

@Kyle-Vander-Ploeg-Wright no there is no problem at all reported in this case. Imo i have less calories from what polar gives me or strava.

Kyle Vander Ploeg-Wright

@Dimitrios-Kanellopoulos you might be right. I’ll need to look into that

Calorie burn depends on weight, pace, surface, weather, elevation gain etc.

That was a trail run with about 360 ft (110 meters) of elevation gain which required extra energy, plus you might be lighter than me.

But whatever, I don’t actually care.

This could explain that:

Workout calories:

Day active calories:

@suzzlo yup

Kyle Vander Ploeg-Wright

I’m still confused by what I’m seeing. I checked how much my BMR is. The watch tells me for my body metrics that my BMR is 1944 calories per day. Which comes out to 81 calories per hour. But if I take away that hourly BMR from my workouts, it’s not enough.

I’m looking at the two photos of the watch showing the calories burned in the workout vs. what it says is day active calories. I still don’t know what math should be done to figure out exactly how many calories you burned for your workout. It’s super confusing.

Hi,

My BMR is 1616, so ~67 cals/h
I started at 9:30AM, and run for 1:30h (9:30 - 11:00) => so there are 100 basal calories + 1311 active calories

So, at 11:00 I have burnt (2048 calories):

Active calories: 1311
Basal calories: 737 (67*11)

Think that these are not exact numbers…, photos were taken at 11:35AM, and workout was about 1:33:41

Makes sense to you?

Kyle Vander Ploeg-Wright

Ok, I think I might know what the problem is. I can’t figure out the math, but I think it’s similar to how MyFitnesspal counts calories for steps taken along with your workout calories (which includes some of those steps taken). Basically it counts double calories. Anyone else thinks it might do this?
