Study proves Fat skis are bad for your knees

I’ve posted several times that narrower skis allow you to ski better and my personal observation is that my knees feel much better on a narrower ski than a fat one.  Scientific studies now prove this to be the case.  Also examines differences between groomers and powder, muscle usage and fatigue and towards end tele

It’s long but worth it to watch if your knees bother you at all

Sorry I couldn’t get it to embed maybe Harv can fix it

Not sure what you are saying here?

As Al Kiner used to say, here's the happy recap:

Don’t know if they’re good for my knees or not but I for one love my old skinny skis and this dude agrees with me

I agree that slide seems confusing without the context of the whole presentation
If you watch the whole thing that slide was used as a starting point of discussion at Psia’s National Academy on how width can be used as a tool.  

The discussion from there was that there are some potential uses for lower end skiers given that the ski is a wider more stable platform but by day 3 the new skier would be on something 70 to 75mm wide.  Sort of a GLM method but with width instead of length.

95% of the presentation covers the negative impact to knees and the adaptation to their skiing that even world class skiers make to their technique to lessen the impact on the knee that then leads to soft issue issues with gluts hamstrings etc etc

I’ve personally lived thru all this experiment the last couple years.  My PT kept saying I can’t understand why your soft tissue gets this f’ed up from skiing.  I went to 74mm underfoot ski and it all went away only to come back in the spring when I brought my 98mm skis back out.

I'm pretty convinced it's old age that's killing my knees.

Re: Study proves Fat skis are bad for your knees

I imagine the type of snow is a factor in fat skis damaging impact?

My knees have been getting pretty messed up the last few years. It’s to the point that I’m ok with taking some time off from skiing.

Re: Study proves Fat skis are bad for your knees

Powder certainly negates the effect on the knee but the study found that the wide skis even in soft snow have an impact on how you ski and that has implications for soft tissue.  It used a min of 11” of pow the study otherwise you hit bottom

I’m not  dumping my fat skis on pow days or in spring corn but I am going to ski on a 74mm width the vast majority of my ski days as a result of this study

Selling my 84mm width as anything over 80 has a negative impact and I found my deacon 74s well out skied my rtm 84

Re: Study proves Fat skis are bad for your knees

I can't speak to the differences between wide and narrow skis and knee pain.

However in the past year, I've ramped up the amount of prehab that I do in the gym.  Clamshells, single leg bridges, lateral walking with a mini band, and other stuff.  RESULT:  I have less knee pain than I did a year ago.

Still lifting heavy with dead lifts etc but the prehab really seems to have made a difference.  I'm even thinking that it's possible to run a marathon again.
