I feel this assessment is made invalid by the runner's uncontrolled sprinting form. His arms swing wildly, elbows abducted, forced bilateral hip flexion/knee drive, strained expression...Even in the posterior view, it is obvious that he is accelerating from a dead stop to near maximal effort. 8:23 is a good example of how much excessive frontal plane movement there is. It would be interesting to see how his presentation would be different if he ran at a relaxed pace...not 50m race pace
Thanks for your comment. We agree his form needs work. This individual is sprinting and accelerating from a dead stop. A more relaxed pace may yield a different analysis, but we are evaluating him as we see him here; other footage was not made available to us
@drwaerlop Was the criteria based on him trying to become a more efficient sprinter, or more efficient runner in general? Either way, I find it comical how far he has to supinate in order to accommodate such an overstride, given his present form
Neither or both I imagine. We were given the footage by a coach and asked to do an analysis, which is what you are seeing. Agreed on the supination; he needs to find some stability amidst all the coronal plane motion, and his tibial varum does not help either...
@drwaerlop True, tib varum combined with the kind of external rotation and medial collapse of the foot during peak loading is an injury waiting to happen. But Tib varum shouldn't be a barrier for efficient pronation loading patterns....I was tough for me at first but I overcame my tib varum (L>R) + leg length difference (R>L) issue over the course of my transition to midfoot running
