Not to nitpick over an idea that I basically agree with, but I have
my doubts about your max HR test for the very reason you mentioned --
lactate threshold. You're only as strong as your weakest link and so, for
anyone but a well-trained cyclist, lactate buildup in the quads would
prevent working hard enough to get anywhere near max HR, even with your
suggestion to ride at a pace where you don't reach shutdown. I run in the
vicinity of 50 miles per week, but I wouldn't reach my max HR by your test
because my quads would tire long before my heart got near its red zone.
The muscular component of any type of endurance training is very
specific to that training, and for that reason, I'd suggest anyone needing
to know their max HR either go with the formula you mentioned or stick with
a test that mimics their typical training; ie., runners should run, swimmers
swim, cyclists cycle, etc.
To nitpick even further, even doing this would't necessarily
guarantee an accurate max HR reading. To use myself as an example, I
probably get as close to my max HR as I can by running 5K time trials. But
even as a runner, I don't know if my legs are maxing out before my heart.
If I spend the next 6 weeks on a running-specific strength program and then
run another 5K, it's possible I'll get a higher max HR even though my heart
is no stronger, simply because my legs were better able to keep up and push
my heart more.
Sorry if this has strayed too far off the topic. I'll return now to
lurk-mode.
