How many G forces

[ericlithner]

Someone who knows how many G forces slalom skiers can be exposed to at most in the course?

I can't speak for shortline as this is just 32mph/15off. But my GoPro accelerometer (chest mounted) shows 1.5-2G (lateral and acceleration) - Gs are plotted just to right of the speedometer here:

Yep. I'm not sure any truly careful measurements have been made, but 2 Gs is a number that has been produced by a variety of approximate measurements as well as by some semi-intelligent modelling that I did a long time ago.

 

So I'm pretty sure it's somewhere in that range for a "good" skier, say running -35 at 36. A bit more for a top level skier, and much, much less for a newcomer to course skiing.

@Than_Bogan I would argue that a "good" skier might sand some of the acceleration spikes off the edges compared to someone just barely making the same pass. So I would find it believable that even lower skill levels see elevated G's during a run, just not intentionally or necessarily to make that particular pass.

Big Aaron Larkin had his telemetry measured a few years back.. at 32’off@36mph, he measured 3G..

From the pros I have skied and worked with they always said they measured 4G at short line 36mph.
