The new formula applies to women over 35. Formerly, everyonewas instructed to use the easy-to-remember formula: 220-age= Maximum heart rate (HR max.) It seems, however, that that formula is based on a study of men only.So, a new study was performed for women.
The appropriate formula for women over 35 yearsis: 206(.88 X age) = HR max.
So, for example, where a 40-year old woman would formerly have had a HR max of 220-40=180. Now, the same woman would have a HR max of 206-(.88 X 40) or 170.8.
Of course, these are merely guidelines, as many other factors influence each individuals' true peak heart rate. But this is a better starting point for many women. So now that you've got the right numbers, ladies- no excuses!
