I do not have a PDR handy and would only read out of it: Ask your
doctor about the effects of albuterol on HR. In theory, if you are going
to take this med all the time, then the MHR on the drug should be
considered your MHR. (Cardiac rehab does the same thing except usually
the *** lower HR.)

A 5K is run at near max. If you are wanting to run a fast time,
it normally is 85+% max or more (have not run a 5K in a while). On a
recent 10K my average HR was 95% of measured max so I would imagine that a
5K HR would be close to that.

Your MHR might be different because then you may have stopped the
test before reaching it (being overweight, I will assume that you were not
very well conditioner and your peripheral system may ahve stopped you
before your cardiopulmonary system did).
If you have another one done, ask them to choose a protocol that allows
you to run at a 0% grade with increased speed every 3 mintues until a
maximum speed for you is reached
(generally about 5K speed). Then have them add grade. This will give you
HRs at various intensities so that you know that speed X equals HR Y which
will help you gauge your efforts. If the clinic has a metabolic cart, ask
how much extra it is, that way you will have a measure of your VO2 max
(the preferred method of adjusting training intensity).
If you like, I can fax or post a protocol for you to use.
I hate the "Zone" and I hate the fat burning myth!
Just so you know where I stand!
