Gene, as I replied on my own thread, rollerski-speeds freak me out, I might
as well leaves the poles at hole and swing my arms skating skeelers?
For each athlete the ideal protocol (highest heartrate reached) will be
different, I think.
Perhaps if a fit cyclist accompanies a runner on an ever-steepening hill, he
could set a pace that would increase ~0,5km/h every minute. Start on the
flat, 7km/u, a mild job. 10 minutes later you're fighting your way up the
steepening hill at 12km/u. The moment you let go of the bike's rear wheel
for more than a couple meters, you ought to be on the road like an XC skier
at the finishline. Maybe harder to execute than I'm telling it.
Bike needs a rear rack and towel for the runner to be brought back down the
hill safely :-)

Jan, try regular rollerskis instead of crosskates, which are more of a
gimmick or specialty item.
The treadmill test has a standard protocol or two. The problem, which
you indirectly allude to, is building up to max HR too quickly.
My experience is that a common way the test is given is relatively
linear in buildup, not allowing sufficient time for physiologic
adaptations at each level. A typical max HR/VO2 max test for someone
with average capacity is done in more or less 11 minutes, with no
warmup outside the test. Imagine going from cold to more than max
(hyperventilation) in a workout in 11 minutes, or a few more for those
of us with higher limits. Some years ago Stephen Seilor of Norway fame
wrote me that tests for Norwegian skiers allowed their normal warmup
and typically took somewhere closer to 30 minutes. That's not all
capacity.

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.
