Max heart rate question Posted: Tue May 24, 2005 1:16 pm 

So we all know the 220 minus your age formula for estimating one's max heart rate. We also know that this formula is definitely not reliable, so my quesiton is: Has anyone had their MHR checked and compared it to the formula's MHR? If so, how great was the difference?

While I've never had my max heart rate tested professionally, I do wear a heart rate monitor pretty much all the time. During half marathons that I run and other races or hard training runs, I've had my heart rate go as high as the mid 170s and even higher. If I used the traditional formula of 220 minus my age, 61, my heart rate should be 159. I use a max heart rate of around 175 when I design workouts using my heart rate reserve as I feel this is probably a more accurate figure.

From my experience and other runners I know, measured MHR usually ends up being higher than predicted MHR using 220-age. I've measured my heart rate up to about 202 a couple of time, but at age 34 it should max out at 186 according to their formula.

My highest measured hard rates seem to happen after a hard workout after a long time off, when I'm relatively out of shape. Once I'm back in shape, I find it very difficult to impossible to get my HR above the mid 180's, which is more in line with the formula.

220 - 14 = 206...

I find that rather funny in a mild way...
