Re: Resting Heart Rate 42 BPM; Good, Bad?

I have the same thing. My RHR gets as low as 40. Since I'm not an elite athlete (I'm 38, lift 3 times a week, do little to no conditioning; bodyweight is 165, SQ 1RM 300) my doc sent me to a specialist cardiologist. Took 3 moths to get an appointment with him (wise old chinese man with degrees from half a dozen US universities). He checked me out and said it's fine. He said they used to think that long distance runners were the only ones with really low resting heart rates, but now they know that sprinters have very low RHR as well.

If you're in good shape, this is a good thing. Like someone else mentioned, the worst thing that can happen is you might stand up too quick and feel faint for a couple seconds.

I think the most extraordinary thing shine I started strength training properly a couple years ago is not that my SQ & DL have nearly doubled, but that my RHR went from 72 to 40-50. And it's not like I was totally out of shape before I began or was over-weight. In fact, I weigh exactly the same (but have lost body fat & gained muscle mass.)

But maybe get your doc or cardiologist to listen to your heart so you have peace of mind.

Re: Resting Heart Rate 42 BPM; Good, Bad?

My resting heart rate has been in the low 40s for thirty-five years now. A couple of months ago it was 38 bpm -- and that was after two cups of coffee. I've always been active; my heart health is just fine. It freaks out most nurses and doctors but what do they know about fit people? Usually not much, as it turns out.

Well, a super low heart rate isn't necessarily an indicator of fitness. There are completely untrained individuals that fall into the same range.

With that said, if you are in good health and have no functionality issues then a low heart rate should be a pretty good thing.

Yeah a portion of it is genetic. My Dad is completely out of shape and in the 40s. It can have something to do with one being parasympathetic dominant.

Do you know your max HR? How is your blood pressure usually and during exercise?

Re: Resting Heart Rate 42 BPM; Good, Bad?

My wife is Italian, her heart rate is very low and her blood pressure is very low. Her Great Great grandmother recently died at 101, her great grandmother is in her 80s and just retired, she used to commute everyday by city bus, her great aunt is 92, her great great grandfather died at 99. I think it's a good thing they all seem to live forever.

Re: Resting Heart Rate 42 BPM; Good, Bad?

Sorry to revive this old thread, but I got a question regarding low resting heart rate...
My resting heart rate (when I lay in my bed for 5 minutes) is about 48. I think this is the lowest HR I've ever measured for myself.
You say this is an indicator of fitness. I agree with that. Strong heart (heart is a muscle and is trained while you train) can pump more blood at once, hence beating less frequently to push the same amount of blood into vein system.
Also, I consider myself to be (somehow) fit.
But my question here is - why is my resting heart rate so low when I'm "idle"? I'm asking this because when I go run and I run at average pace of 5:00/km (which I can do quite easily), my heart rate goes well above 170. That's like 88% of my max heart rate (I'm 28, so 220 - 20 = 192)?
Is this normal?
Thanks.

Resting heart rate isn't just about how strong your heart is, aka, how much blood it moves with every beat. It's MUCH MORE about how much oxygen your body needs. Better shape = lower demand. It's a combination of both factors, among others.

So what you are describing is very common, especially for cross training athletes. Crosstraining generates a strong heart, without necessarily training a hugely efficient body. By HIIT, your body gets a chance to recover between rounds, so it doesn't have to adapt to be as efficient DURING the rounds like an endurance training program might generate (learned this lesson the hard way).

So a crossfitter will be able to take on short bursts with a lower average heart rate than an endurance athlete would, whereas an endurance athlete will be able to maintain a lower heart rate over long phase exercises than the crosstrainer would experience. Your body adapts to how you train.

To the OP, I've had a resting heart rate in the 45-55bpm range for about 15yrs that I've been keeping track. I also have hypotension, aka low blood pressure 80/40 resting.

Although I get a clean bill of health from the doctors and trainers I have worked with (the typical "congratulations, you're as fit as a horse"), the downside is that hypotensive shock is never too far away. It's very very easy to pass out from shock when you operate so low. Never usually an issue during an activity and adrenaline is flowing, hr is up, bp is up, but say I get stepped on by a bull and break my leg, about the time I get in the ambulance, resting, laid down, I'll pass out. Nothing really bad, just sucks passing out, and freaks out the paramedics.

Re: Resting Heart Rate 42 BPM; Good, Bad?

Sorry for late reply. Thank you for your answer. This makes sense.
So how about blood pressure? Is blood pressure related to heart rate? In my opinion it is - as heart is what (mostly) causes blood pressure, right? The other factor would be the elasticy of veins / arteries?
I've measured my blood pressure few days ago (made 3 measurements with a pause in between) and my blood pressure was 115/78 which is (according to this blood pressure chart http://healthiack.com/health/blood-p...pressure-chart) quite optimal?
The stronger and healthier the heart, the lower the blood pressure - is this statement still valid nowadays?

Thank you.

Resting Heart Rate 42 BPM; Good, Bad?.....

A good measurement of knowing your fitness is to check your resting heart rate and then see what your maximum heart rate is and then see what the difference is.

If your max heart rate is high compare to what it should be then you are in good shape...

I have a resting heart rate of 41-44 strait after i wake up in the morning without even getting out of bed and my max heart rate when i have gone to the max should be 220-44 (age)=176 but when i max out i can push myself and hit 188... so my heart range is 142bpm which is really good.

I can't rememebr what they call this but i am sure someone knows.

This is a great measure ment of your fitness.

Re: Resting Heart Rate 42 BPM; Good, Bad?

Im not sure about that Alex. I am 33, my hr in the morning is 50 and my max is somewhere in the 185-190 area.

And I most likely cant run 5k in one piece, my conditioning is simply terrible.

Ive read/heard that fitness can be "measured" how long it takes for your HR to return to normal after being at max.
