Lindsay Williams working the treadmill. Acutally, here she's just cruising along at a HR of about 130bpm, but she threw down a little bit later on the max portion of the test. Troy Flanagan is sitting at the table, absorbing data. Vordenburg is ducking around taking pictures.

Fill out short background form.
30min warm-up skate skiing outside.
Measure body mass, put on harness.
8min warm-up on treadmill, w/out mask, 4min really slowly, 4min slowly.
Break to take lactate, put on mask.
5min at 4% grade, 3mph. Take lactate.
Repeat, increasing +1mph each time until lactate goes above 4mmol.
20min break, spinning on stationary bike.
Return to treadmill, same 8min warm up w/out mask.
Start at 2mmol speed/grade from previous test.
Increase grade 1% every minute.
Until you fall off.
Take lactate 0, 5, 20 min after end.
At least that's pretty close. I didn't pay too much attention to the details, I was mostly concerned with skiing.
This was my first time rollerskiing on a treadmill. If you can handle the sensation of riding rollers, you wouldn't have any issues with rollerskiing on a treadmill. We're on some kind of green rubbery mat so the poles stick really well without having to be very sharp. VO2 max testing isn't as tough as it looks-- only about 1 minute out of the whole testing procedure is rather painful, the very last minute on the treadmill. There's a harness so you don't have to worry about hurting yourself if you fall. Although I didn't fall, they turned off the treadmill before I'd stopped skiing. I was on my way off the back, but I hadn't actually given up yet. The worst part by far is wearing the mask and having your nostrils pinched shut with a nostril clothespin. Since you can't swallow very well with a big tube in your mouth, you end up getting everything nice and slobbery and when you take off the mask there's a nice slobber waterfall. You don't think about that when you're actually skiing though. I haven't seen any of my graphs or numbers yet, the sports science guys were pretty busy and have a week of very long days so I didn't want to bother them with questions.

FASCINATING. I've always wondered about these tests were like. They don't sound fun, but they must be informative! Surely you'll share your HR data: where'd you max out, and how long did it take?
MMM, I love these things. I haven't been to facilities that have a ski tredmill, I've only done them on bikes and running, but they hurt all the same. The lab I work in has a new producr for the air echanger, its actually a little mask with a digital analyzer in it, so there's nothing stuck in your mouth, and there's only wires coming off, so it doesn't throw you around like that damn hose does. We're going to test it a bunch this fall to compare it accuracy against the old standard, I'm hoping these work.
Looks kinda freaky to me. But then, I've never gotten the hang of roller skis, much less roller skiing on a treadmill. What's that about "old dog and new tricks" ....?
I will have to get the USSA sports science team looking at Howdy's new air digital analyzer mask-thing. That sounds way nicer. I think we have to wait a week or two for all the results. Justin & Troy have to meet with the coaches and then write up a little analysis of each of us.
