Long term RHR in an ex athlete

cross-posted from: https://lemmy.blahaj.zone/post/103924

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.
