After reading this paper, I have no idea how this phrase "complete breakdown of mechanics" applies to the slight alterations in rearfoot motion seen in this study. It certainly doesn't seem like a phrase I would have allowed as a reviewer in this paper to describe the changes in rearfoot kinematics seen in this group of runners. What exactly does a "complete breakdown of mechanics" mean in the Journal of Biomechanics? Sounds rather dramatic and un-scientific for a scientific journal of this caliber.

I wish that were the case, Simon. Here is the first two sentences from the conclusion of the paper:
Paper is on its way.:drinks -
Thanks Kevin. In which case that's an outrageous over-statement. Indeed, they say themselves: "Based on these results, runners demonstrated subtle changes in kinematics in the exerted state, most notably for eversion."
So "subtle changes in kinematics" = complete breakdown in biomechanics. :morning: Nice work. :wacko: -
Here's the curve that demonstrates the "complete breakdown in mechanics" in the rearfoot....a whopping 1.5 degree change in peak rearfoot eversion angle!!:bang::craig:
The bolded line represents the end of the run, in the "fatigued" state.Attached Files:

Instead of saying:
"The study showed that rearfoot mechanics changed slightly with fatigue, with rearfoot motion changing 1.5 degrees, which when considering the known skin to bone artifact seen with kinematics studies that use skin mounted markers may be an insignificant change. However, the 1.5 degree change in peak rearfoot eversion seen with fatigue may represent some change in skeletal motion of the rearfoot with fatigue, but certainly should not be considered to be a complete breakdown in rearfoot biomechanics.
In addition, the slight extra rearfoot motion seen with fatigue is most likely the result of the muscles, tendons and ligaments exerting less internal supination moment as the run progressed into fatigue. The extra motion may or may not make it harder for the muscles, tendons or ligaments to handle the strain forces related to running." -
