This is a great list of responses, with most people saying "no, they don't limit HR." I've asked my doctor a few times, and he give a pretty measured answer, something like "it's probably fine to max your HR." Note the word "probably," I think there's always a small chance that, if you have a heart problem, it could manifest during exertion. C'est la vie!
Anyway, I attended an indoor running class complete with loud music and a DJ last week. We were encouraged to really push it, and I did. My max sprint was 9MPH on a 1% incline (for about 30 seconds) which gave me a max HR of 170BPM. I'm 57 years, so this was much higher than recommended (on average), and I feel like it left my chest a little sore . It certainly left one knee a little sore! But, a few days later, all is OK, and I suspect I'm better for it!

There are training methods that use low HR to improve performance, like Maffetone's. I have friends who have had success with that. I don't use it. My HR is somewhat erratic and usually quite high. I live in a hilly area so every time I go up a hill my HR rises and stays up. The numbers that Maffetone uses as training goals are only possible for me at a walk, not a run, so not helpful.
