At 57, my max HR should be around 163. On a 30 mile ride today, and I've only been riding this time for about 6 weeks, I averaged 15.2 mph in the south Florida heat. My avg HR was 108. My max HR was 136. I have no idea what my actual max HR is, but I know I can pretty much cruise at 17 or 18 mph at around 110 HR.
Is that a weird heart?

Maximum heart rate is called maximum heart rate because it is MAXIMUM rate of heart person can achieve during exercise. Exceeding maximum heart rate IS NOT POSSIBLE! Over time maximum heart rate will drop, but it won't get higher. EVER! Period. However, it is possible to exceed predicted maximum heart rate based on averages. Those two are different things.

You have to understand that the 220 - age is a general guide line. Peoples general health will actually dictate their actual personal number.
It is and average for all people. In a way averages dont mean much. If I place a piece of dry ice in one of your hands and a lighted match in the other, on average your are comfortable.

Here's a reference that describes the history of the formula: https://www.researchgate.net/publica...0-age_equation

Yea, don't bother with that stat. My HR has hit 190 in the last year once or twice and I'm 65. I asked my cardiologist about that and she said that if I'm still here to ask I'm OK. I regularly hit 180 climbing and don't give it much thought as it always retreats as soon as I let up.

It's an extremely poor guideline for older people since it was based on a 1930s ad hoc straight line fit of data from young people that was not statistically determined and has subsequently been shown to be a poor fit of even that data. Not only was the methodology poor, but it is completely irrelevant for people over the age of about 30.

My theory? Hearts are (and are like) pumps. Some are big and pump a lot each beat. Some are small and have to pump faster to supply the same amount. If your body was equipped from birth with a big MTB floor pump, it would adopt to a much slower cadence than the body equipped with a mini-pump. No formula based on just on age isn't going to handle both of those pumps.

This thread is from 2006, apparently revived by a troll who has posted once in 3 yrs. OP Denverfox has been MIA for
some time and would now be 81-82 yrs old.

It is a plausible conjecture that neurological changes might alter (increase) someone's maximum heart rate. After all, that's what happens during an SVT heart attack when your heart rate exceeds your "maximum".
