Pure curiosity: what is your avg heart rate walking 3MPH on flat surface for an hour?

Hey Guys,

This is purely out of curiosity.

1) If you walk 3 miles an hour for an hour on flat surface, what is your avg heart rate for that 3 mile walk (using chest strap)?

2) If you don't have that exact data, can you please share estimated results for a similar 1 hour walk at a constant speed on a flat surface?

Please share your avg resting HR and Max HR, and what HR "Zone" you are typically in on a walk similar to this.

Background info: I'm 34 years, 6% body fat, 5'7 height, about 132lbs. My avg resting HR for a day is typically 33 and my HR Max is only 155. I climb 1000-1500 floors per day on stairmaster in HR zones 3-4 mainly.

If I walk 3MPH for an hour on flat surface, my AVG HR is only like 50 (NO hr zone), and I burn only like 60 "active" calories.

3) I'm just wondering how common it is to have such a low HR for something like this (at least I think it's low?).

4) Does anyone else have a situation where Garmin calculates your BMR/Resting calories per hour to be higher than such an activity? For example according to Garmin if I do absolutely nothing for 1 hour I burn 75 resting calories, yet the active calories on my watch only go up about 60 for a walk like the above, which is still driving me bananas.

5) Does anyone else agree that Garmin calculating my BMR as 1800 seems way to high (75 calories per hour doing nothing)? I think I'm in the 1300-1500 calorie BMR range but could be wrong.

I'm really interested to see what others are experiencing with this out of pure curiosity. Feel free to share any other interesting calorie burn stuff you have noticed as well.

Look forward to your replies.

Best Regards,

    1: checked a recent activity, about 88, but I walk about 6kph. Average HR zone of 0.8. Some hills were involved (no where is flat here)

    2: see 1

    3: no idea, not done the study, but you are walking slowly on on flat ground, it's not taxing

    4: your active calories are in addition to resting calories, your total calories required over that time frame are active+resting. So in your example you are burning 60+75 when walking, not 60.

    5: your BMR is linked to your genetic gender, your age, your weight, ensure those are correct, it's also the base requirement for you to exist. You might think you are doing nothing, but thinking, walking, breathing, pumping blood round your system, keeping the heating on all takes energy.

    Your resting heart rate is very low, you either have heart issues or are extremely fit. You are not going to do a big calorie burn walking. Try running if you want to burn more calories.
