Warren Wilson said:Hi group, I want to ask about Heart Rate.
I am 43 years old, and feel pretty fit, but not a Lance Armstrong.
My HR at many times goes well near 95% of my maximum, but I don't feel like
am pushing myself that hard.
I am 43, so my maximum HR should be 177, Age - 220.
Any advice ?
I'm a year younger and reasonably fit but average only about 70 - 120km / week, mostly recreational with a littel club racing thrown in.
My max HR seems to be about 193. At my "theoretical maximum" of 220-42 = 178 I know I'm working but can certainly go harder. I get to 95% of 178 going medium hard up just about any hill. So in my case (and plenty of other people) the formula for Max HR is pretty meaningless. As someone else said the only way to find your true max is to go as hard as you can (for about 60s).
Just for reference, the highest average HR I can sustain for different lengths of effort (climbing) are:
~10 mins : 186 (= 96% max HR)
~20 mins : 182 (= 94%)
~60 mins : 175 (= 91%)
(and after any of those efforts I'm toast for the rest of the ride)
These seem like very high figures to me and really fit riders seem to be able to go hard at much lower HRs than I can.
