Measuring skier watts?

Postby JeffOYB » Fri Jan 12, 2018 8:28 pm

I feel I've brought this up before but I did a search and came up empty.

Is there a handy way for skiers to measure watts? I would think that one of those skiable treadmills could just have a wattmeter on it and however fast you could get it going would tell you.

I recall discussing this somewhere and folks saying it wouldn't work.

You can easily measure watts on a bike. ...What about a poling machine? A Nordic Track? If you can somehow be making an axle turn can't you just hook up a wattmeter to it?

If this can be readily measured -- and is -- I wonder what kind of watts skiers put out. Coz they're using both arms and legs.

The concept 2 skierg measures watts perfectly. Best exercise investment ever! And if you're wondering why Sadie Bjornsen is killing it thus far I think the skierg is a good place to start!

cool -- now they need to add in a leg machine and add the watts from that.

what kind of watts do skiers generate on the ski erg 2?

When pushing hard I can average ~ 275 watts for a 5k which takes about 18 mins.

I'm not sure a true full power meter exists for nordic skiing. As previously indicated, ski ergs do it.

This patent was filed in the last year or so though. Again, a brief skimming I believe it is only for poling power and doesn't get the full workout if you stride or skate.

DCPattie,

That is an impressive effort, how old are you and what is your weight? If I can put out 200 watts for one minute repeats I am happy. I'm 54 and 75k.

SkiErg does a calculation of meters/pace to determine watts. not a real wattmeter. or maybe none of them are? no, the ones mounted on bike-parts (hub/crank) are real. couldn't a real meter be mounted to any axle? so a poling axle and a striding axle...

I see that NordicTrack has a new machine that measures watts but it looks kinda lame. well, for integrated allbody work anyway. looks like you put a cable to one foot at a time. ugh. https://www.nordictrack.com/fusion-cst-series

I wonder if the original NT could have bindings put onto its boards. It has 2 axles that could be wired to measure watts, doncha think? then combine them in the read-out.

Yeah, i know the NT doesn't do doublepoling but DP is lame anyway. ha. ok, it wd be nice to do. i wonder if they could make their poling "stand" somehow do both.
