Around 7 years ago, I was a sub elite runner, and I did a lot of cycling as cross training. My resting heart rate got incredibly low during that time.
However, these days, even though I’m relatively unfit, my resting HR pretty much hasn’t come back up from where it was when I was an active athlete.
Has anyone else found something similar? It’s easy to find active athletes with low resting HR, but I don’t really see much discussion about what the long term change to HR is in ex athletes.
I was very fit! I kinda miss it, but not quite enough to do the training to get back there :)
lol
I do know there’s some data in athletes who have exercised-induced arrhythmias that a period of de-training can resolve them (and they don’t necessarily come back with resumption of activity) but I don’t recall seeing anything about resting HR. Some of the changes that accompany training like increased stroke volume, chamber size, parasympathetic tone are reported to revert after de-training, but not sure if all the way in comparison with a never-fit person
I just went and did some digging and found an interesting study (which I guess I could have done before posting, but what fun would that be?)

And that does seem to capture me. < 50 bpm, with no palpitations, dizziness or syncope, or major ECG alterations.
So I guess that answers my question. It’s relatively normal in ex athletes, even if not common
do you still exercise at all? I bet even a little might be enough to keep some of the adaptations as opposed to being completely sedentary.
Great find on that article, thanks!
I scored a bout of pneumonia just before covid hit in 2019, and I was basically sedentary for 2 years after that. That pushed my RHR in to the high 40s.
These days, I do exercise a little now and that has reduced my RHR back down to the low 40s. That’s still higher than it was when I was an active athlete though
