Female Max. Heart Rate(3 posts)

Is the approximation of 220-age = MHR valid for females? If not could someone out there give me a good guideline to follow?

But why waste your time with these nearly useless approximation formulas. Presumably you're wanting to actually do something with the knowledge of your max HR. You'd probably be better off basing training on your AT/LT (anaerobic threshold/lactate threshold) which is 97% of the HR you can sustain in a flat-out 25-30 minute ride (time trial). Alternatively, your HR during the time trial is 90% of max. Calculating max based on an age formula is darn near useless in trained individuals (my "calculated" max is 168, my actual max is 190.)

I wish someone would lay the 220-225 minus age formula to rest permanently! Basing
heart rate zones on TT-associated heart rates is much more functional by any standards.
Even determining max hr from a ramp test in a lab, from a training perspective, is really
useless. As has been pointed out countless times by coaches, physiologists, and other
training types, lactate threshold and power at lactate threshold are the training gold standards.
