When is low too low - RHR(7 posts)

When is low too low - RHRChazman
Mar 3, 2002 6:01 AM
Since I started training for running and biking about a year and a half ago my RHR has lowered from the high 60's to about 45. I am told this is as an indicator of fitness. I am interested in performance but also doing this for long-term health. I am wondering if a low heart rate can cause problems when we get into our 60's and beyond. Especially since your RHR decreases with age. Any info including web article references would be appreciated.

Well, I'm off the the LA MArathong bike expo. I'll see if any sports medic reps are there and if they have opinions.

Basically three reasons for a low RHR: genetics, disease, fitness. If genetics is the reason, you're probably OK (unless it's bad genetics). If disease is the reason, you need treatment. If fitness is the reason, relax and enjoy what you've worked so hard to get.

there are no long-term consequences of having a low RHR - your heart will simply work less over the course of your life. don't worry about it unless, as cyclopathic said, it drops to zero.

Doc has NO problem with it at all... No worries. As long as your BP is normal and doesn't drop accordingly then your good to go.

There are several causes for bradycardia (low heart rate). If it is because you are in good shape it is ok since it can speed up when needed. What happens in old people is that the nodes (natural pacemaker) and nerves in the heart wear out and the heart beats slowly and can't respond to activity and increase in rate. This can cause syncope (blacking out) and other problems so it's time for a pacemaker.
