Dr. Kim Hewson attempted to post the graphic below in a comment on my post, MIKAELA SHIFFRIN AND THE SIDECUT FACTOR . Since comment fields do not enable attachments, I have posted Dr. Hewson’s graphic below.
I agree with Dr. Hewson’s position. If your knee ever angulates, I suggest you seek immediate medical attention.
In the series of posts on THE MECHANICS OF BALANCE ON THE OUTSIDE SKI, I will explain why the knee of the outside leg of a turn in racer’s such as Shiffrin has minimal internal rotation under torque high loads.
