heart beat rate before/after excercise

A number of years ago I saw a report that suggested there was a correlation between heart beat before and after exercise and the chances for stroke or heart attack. More specifically: if within a minute after ceasing a strenuous activity the heart beat does not fall by at least 12 and at best by 20 beats, that person is statistically more prone to a heart attack or stroke than someone whose post -exercise heart beat does fall within that range. I have advised people of this research especially when I'm working out but am now beginning to wonder . So few people seem to have heard about this neat little formula it makes me think this may have been of these little research reports that pop-up and then disappear because they have no real basis. Anybody know?

yes, excellent, simple test. see:

thanks. I'll be posting a print out at my fitness center.

The closer you get your heart rate to its max, the better. You can also try it at 70% of max - if you exercise you should still get a drop way more than 12 beats. Mine is about 30 beat drop. Check with the Cleveland Clinic website for more details (they did the research).
(note, the smaller pc of max you get your HR the smaller the dropoff you'd get)

I'm sorry, nwberean, I have now edited it. It was a spam link taking one to all kinds of different sites each time you'd click on the link. My apologies for not seeing this sooner
