Hi all, I'm J, from The Netherlands, 29y/o.
I'm new here, this is my first-ever newsgroup post, hope all works out okay.

When I was at the gym, many years ago, I helped the manager figure out the
new treadmill and it's built-in software. One was the "Bruce Test", and I
was appointed volunteer to take it. Instructions said to keep so and so many
nurses and so and so many doctors with heart equipment ready. It's a hard
test.
It started with a relaxed walk up a slight slope, and over the course of
maybe 5 or 10 minutes, speed and slope were increased, till at one point I
ran 10.8km/u at 14% I think it was.
I had to indicate a couple seconds before totally crashing down, so the
emergency button could be hit and the mills brought a a no-too-abrubt halt.
My final heartrate was 203bpm. On a bike, I am a mountainbike racere, onder
many different conditions, I had always given 195 as a max.

So if you have a similar hill around, and used to some running, warm up a
bit, and then attack the hill with an ever-increasing intensity such that
you pretty much drop dead after a minute or 5-10. On a bike a test up to
20mins is fine. As long as the heartrate and intensity are increased fast
enough that fatigue is not a factor, neither is the slow response of the
heart, and not too quick for the muscles to run full of acid.

I'm a XC ski newbie, never done anything but one evening of indoor
snowboarding, and my mind is now set on becoming an XC skier in a pretty
much snowless country. I'd be interested to see myself beat my own present
running max heartrate (it's bound to be lower af ter a few years) on ski's,
ever. My first attemps on my www.crosskate.com skates hardly see me get
aerobic at all, due to toal lack of skills. I get exhausted though, and want
more.

I'll be reading back 3200 posts now,

A max HR test of the kind you ran should be set up as a series of
~1-minute runs (after warming up), building up to a final go (typically
4x). There's a track test that's good for this with running (do a
google search), or you can use a long hill, such as that bridge.
It helps to have a friend to hold the watch and egg you on. Steve's
correct about the usefulness of LT for most of us. Do you have any
1-2hr ski race results? That will give you an indication of your LT
for that length of time, tho note that skating HRs will typically be
higher than striding (and on snow a bit higher than rollerskis). For
running, to clarify, the LT-HR is the highest one (hardest) at which you
can maintain a steady pace (once warmed up) for 30-60 minutes. Piotr
Bednarski (http://www.gotraining.us/) does multisport lactate testing
in the TC and Prof. Dan Carey of St. Thomas does testing on a treadmill
or bike in their lab for a relatively low fee
(http://www.stthomas.edu/hhp/FacultyIndex/Carey.htm).

You max heart rate will usually be higher for sking than running
because you are using your arms as well. More muscles involved, more
load on the heart, higher rate. Most people base their training zones
on Lactate Threshold heart rate. That is because LTHR is a better
indication of potential and it can be trained. LTHR is the item you
want to get higher. Read up on it. A good way to determine LTHR is
to go as heard as you can for 30-60 minutes and take your average HR
during that period. Then look up the zones bases on LTHR and plan
from there.
