Heart rate

Hi,

I’m 30 years old, bmi of about 26, completed couch to 5k a couple of months ago, and before that had done not much exercise at all and have a sitting down job.

My resting heart rate, according to my Fitbit is around 51-56, which Googling tells me is a bit on the low side.

When I run though, even if I go slowly, my heart rate seems to go up to 150-165.

Should I be concerned? I have tried to do runs where I deliberately go really slow to keep my heart rate down, but it always seems to end up pretty high!

You seem as fit as a fiddle to me but I’m not a cardiologist.

That heart rate is low.

The theoretical maximum HR for someone your age, using the somewhat crude formulae, would come out at 190bpm, so your 165bpm is well below that.

If you feel fine when running and recover quickly and have no palpitations, then you are probably fine.

An easy conversational pace equates to approximately 75% of your maximum heart rate, which is the perfect zone to build the solid aerobic base required to run faster and further, which is why it is the pace at which elite athletes spend up to 80% of their training time.

Can you speak aloud, clear, ungasping sentences as you run?.........if not, you are going too fast.

I would say that your resting heart rate is really healthy & your heart rate when you exercise doesn’t seem to be excessive ( I’m not a doctor though!) My heart rate has gone up to 170/5. Max heart rate is roughly based on age.

My resting hr is between 53-58.

No. My resting heart rate is 40 or less usually. I’ve just had loads of tests done. Cardiologist said it’s fine as it goes up in exercise. Only be concerned if it doesn’t go up. Yours isn’t low really either.

Thanks for the reassurance everyone :)

I have constantly worried about this. My resting is 55 but running about 160. I think it picks up on your steps per minute tbh (believe it is called cadence lock). As an experiment try waving your arm around while you are sitting down. My fitbit says my heartrate is 160 after a minute or so... Clearly its not. I am trying to not worry and go by how I feel.

There’s nothing to worry about. Yours are totally normal.

That sounds fine to me; quite similar to mine. If worrying about it is spoiling your enjoyment of running, I'd turn it off and just go by how you're feeling.

Yes. Cadence lock is an issue with some watches. I bought a chest strap and it’s much more accurate and reliable than the optical method the watches use.

The theory is the more volume the heart can pump per beat, the less often it has to beat.

My heart rate drops to about 55 bpm occasionally when I'm sleeping. My usual resting heart rate is around 62.

A colleague is like Tasha99 since he started exercising regularly. This really confuses heart rate zoning apps, as his active HR is highish.

If you're not feeling faint when standing up from bending down, you're probably OK.

(I get postural hypotension [POTS] -- that's common with h-EDS. Now I've started running and got active, I absolutely need to keep it up. But that's another story.)

My heart rate drops to 47 in a deep sleep. I feel fitter now than I have for 30 years. My heart rate recovers quickly and on Sunday I ran slowish for 46 minutes and could speak normally as soon as I stopped. Sometimes I think we get hung up on the numbers and forget that our bodies will tell us when to ease off!!

The availability of these numbers can give folks some anxiety - a case of too much knowledge. When these metrics were not available, no-one had anything to worry about. But there's a balance - use and understand the metrics in the right way and they can be very useful and advantageous.

A low resting heart rate (RHR) is good sign of fitness. I'm 51, have a RHR of around 45 and a maximum of 179. But I make sure nearly all my runs are done at around 125-130 .

I'm trying to keep my speed slow to keep heart rate down but difficult when I don't know how accurate wrist based fitbit is.

Quite inaccurate. The only really accurate way to check your heart rate is with a chest monitor.

How about ditching the Fitbit and just running with a stopwatch?

What did you buy the Fitbit for originally?

Does heart-rate stuff really interest you or is it just a metric that came with the Fitbit and now concerns you unnecessarily?

I got it over a year ago to try to get more active which has worked well. Had already walked far more before I started c25k. I do like it for runs because I like the stats and it seems good for splits etc.

Resting heartrate seems accurate but just not sure about when I am running. As I've said before, it can go up to 160 just waving my arm around sat on the settee. I got a bit hung up on it I suppose. As long as I feel ok I think I need to trust my body.
