That's funny, and actually I'm the same having never tested my HR in my sleep.   But for finny's benefit my 'usual' HR shortly after waking and prior to getting out of bed is 44 - 47.  HRmax is 196 and I'm a 34 years old male.

Wearing A Heart Rate When ASleep And Pressing The Start Exercise button Will record it when Asleep

LOL @ UCB. I was going to say the same. When i first got the new HRM 3-4 years ago, i did wear it around anywhere and everywhere to suss out these things. I did the download of the data back then and most of the readings were the same as my resting HR of 46-47. There weren't any smooth little waves of peaks and troughs like i thought might be the case. And yes, i had a quite few readings of Zero. ONly for a short time thankfully    i was surprised that even during sleep, the HR was not apparently lower than my Resting HR taken first thing in the morning.

My just after waking rhr is around the 60 mark.

My wandering around the house not doing much has recently gone from the 90s to the 70s though....but the rhr hasn't changed....go figure.

At my age am pleased to just have any heart rate at anytime  

[Swaggers]

Remember John Farrington?  He won City to Surf in 1972,1973,1974; the 1973 NSW marathon in 2:11; came fifth in the '74 Commonwealth Games and a bunch of other stuff.  I recall reading somewhere that he had (when awake) a resting-heart rate of 28.

Can dreams alter your heart rate when you are asleep? I imagine they can...depending on the dream of course.

Really Wondering Why You Post In Title Case.

I have never owned a monitor with the capacity to show lowest ad highest heart rate, so never tested a through the night reading. My regular RHR in the morning is 28 with the odd 27 showing up. I don't know if at sleep a heart rate would get much lower than a prolonged at rest rate.

B+ you could cook a baked dinner between beats your heart rate is so slow.

OK, this is an old issue, and was discussed few times previously.

There are technical and physiological reasons, why the lowest number from HRM is meaningless.

short ex[planations of them will just bring in confucions and meaningless arguments and proper expalnations of them will take few pages and still might not achieve clarity.

Instead I will just stick with the conclusion :


Count the beats for at least 15 minutes and divide the sum by the number of minutes.

This and only this should be considered the HR so in this case the resting HR.

at higher HR's and during exercise these technological and physiological issues become less and lees of an issue, so could be comfortably disregarded, as is the normal practice.

while some people do claim there si not a difference in the resulting number, for many there is.

The guy, who has extremely low resting HR - lower than any known runner,

does exact procedure - count the beats for 15 minutes and dived by 15, and this long time average is what he officialy takes as the low resting HR.

Idealy You should see variation in electronicaly recorded data and get some 15 minutes sliding average value, but that is still not 100% accurate.

[Huff]

Ok, I'm going to sleep with my hand on my pulse but i'm forgetting to start counting once asleep...

I am very intrigued!

I have been grappling with my garmin readings on this particular run (graph attached)  which was recorded  on a 2 lap Quarry Road bush run (Sydney) (total distance 26 kms at 5 mins 38 average pace). This one was not consistent with many other similar runs, so doesn't pas the 'taste test' for me.

If it is to be believed, as i ran up a particularly steep bit,  my heart rate dropped several times to a low of 30 bpm. ie..almost clinically dead, but certainly did not feel that way! The average for the whole run was 96 bpm, which also does not correlate with my regular average ...

I have to add , that i do regularly record at 30 bpm resting and sometimes during lower effort exercise such as kayaking or cycling....

I am doing the 15 minute counting test in the am and will check back the result!

Just looking at this HR trace you can see that the HRM is intermittently losing it's signal - there are segments where the HR stays exactly the same (regions of flat lines). Sometimes this happens and there isn't a lot you can do about it. That is why it is always worth having a look at the trace. My bet is your heart rate did not go down to 30, they were aberrent readings. The nature of the technology.

[walker1st]

Johnbo, in my view the graph is not realistic, it must be something with the equipment or attachement to the body or interference with some outside electronic noise.

You would be better to go to the track and run even pace each km and gradualy increase teh pace for each km and show us such a graph, starting from slowest and building up to whatever speed You decide to call it a day, I am not pushing You too high.

[mgi11a]

I recently wore an ECG for some tests for 24hrs, a fair bit more accurate them my garmin i suspect.

Anyway the good news is there was nothing nasty happening with my heart, but I did find out that my minimun HR was 27, I don't believe this is the same as a resting HR which I believe to be 38bpm.

I tried to quiz the cardioigist a bit but he was more concerned asking about $.5M house renovations.

There is a problem somewhere.  Probably the strap is not reading your HR reliably (too tight, wrong position, too much fat, low blood pressure, battery dying) or there is a problem with the garmin device decoding the data that is being sent.  Or it's possible (though a virtually infinitely small probability) that you have a very strange circulatory system.

[slowboat]

Just when I wake up recorded 23bpm, don't know what it when I was asleep and resting was around the 35bpm.

Bummer!

So I cannot claim to be of similar genetic makeup to Lance Armstrong then?

A much more typical heart rate for me @ say 5 min 20 pace per km is this.

Yours somewhat deflated,

@Finny: I'm not sure whether the point of this thread was idle curiosity or some kind of attempt to big note yourself, but in any case, RHR has no correlation to fitness/running speed. You can have a RHR of 20 and still be a hopeless runner. That is not to say that measuring RHR has no value. It will show fitness trends over time: for instance, my RHR was 50 when I first started running, and is now down to about 35. It is also useful as a way of monitoring overtraining: if your RHR is significantly higher (say 20%) than usual, then this is a warning sign and you should back off to allow your body to recover.

Bruncle I'm not sure of the point of your first line of your post other than an attempt to give some one a hard time, but in any case, RHR does have a correlation to fitness, as you point out when you started it was 50 and now it is 35. Most people will see a drop in their RHR both on waking and when just at rest, once they have gone down the path of doing regular exercise.
My tip is the thread was for curiosty as we are are interested to see how ourselves and others respond to training and other lifestyle changes we make.

Fair point, I was being a bit malicious. Boasters (have a look at the numerous other threads he has started) get on my nerves.

What you are talking about is not the same thing as a correlation to fitness. If there were a correlation, then one would be able to use statistical methods to come up with an equation that would take resting heart rate as an input and spit out some measure of fitness, such as VDot value. This method would only work for individuals. You cannot compare RHR between athletes, it is basically meaningless. Some elites have RHRs in the 50s or 60s, while some are in the low 20s. In this case, there is no rule, only exceptions.

From what I remember both his brother and father are the same. He has been like that all his adult life. No history of heart disease in his family either.

[predator]

Mine is pretty low as wel, in the 30s. I had a GP who checked my heartrate and it was so low, he asked if he could hve another listen because he doesn't get a chance to hear a healthy rate very often. LOL!

I swam an a fairly elite level for many years and have been told that is the reason why my HR is so slow. It kind of freaked out the docs when i had a major operation recently, i'd fogotten to mention it and they thought i was going backwards after the op - till my husband explained.

will go and do the proper test now just to see what it actually is!

Back in my early twenties, I remember taking my pulse in the morning when I woke up many times and it was usually 36-38.  I was a 14:445k / 30:28 10k / 2:22;34 marathon racer at the time.  Now I am a 51 year old runner who did 17:43 a couple of months ago, a 36:53 10k and a 3:00:33 marathon.  I haven't taken my pulse in the morning, but just took it while sitting in my reclining chair, watching television, drinking iced tea and working on my computer and my pulse is 52.  I'd guess it's in the low 40s upon awakening.

I find it funny reading this from this angle. When I was in hospital getting my wisdom teeth out and woke up from the anaesthetic the machine kept beeping alarmingly indicating my heart rate was low which nearly gave me a panic attack and I keep trying to breath faster to speed it up as I thought I was dying. I didn't realise that it was a good thing that people actually desire to have til later.

[Bellthorpe]

Having been monitored continuously for a couple of weeks last year, I now know what my heart rate goes down to when sleeping (or just lying around doing nothing) ... 32.

[Nurse25]

At work I've had a patient (very fit marathon runner) who had a resting heart rate around 38bpm. Checked mine when I woke up today and it was sitting around 63-65bpm

[iRonnie]

Sometimes it gets plenty high when on CoolRunning .  Usually around 40 on waking.  
Is 58 right now.

Edited by iRonnie, 06 April 2010 - 04:54 PM.

[blacky229]

My heart rate just after I wake up is around 35-36, but if I have a hard session the day before it is usually around 38

[Tiddischer]

As if a low heart rate was something to be proud of ...
Nor is it a special sign of great performance.

Almost everyone being healthy and at a fitness level of maybe 45 min 10 km or faster has a heart rate around 40 +- 10 bpm.


It would be the same if you told us "I ran my last  1500 m race with a heart rate of 195"  -  anyone knows anything then, whether it was a 3:30 or 6:00.

So please stop senseless threads like this one.

the problem is you only realise something pisses you off after you've read it.
then its too late.
i prefer reactivation of old threads than multiple new threads on the same theme.
eg. hi i have been running for a few months and was wanting new shoes what type should i get?
a week later...hi i have been running for a few months and was wanting new shoes what type should i get?
