Why the most commonly prescribed running fix is usually treating a symptom, and what the plate data actually points at instead.
Raising cadence hides a problem for about three weeks. It shortens the stride, moves contact under the body and takes the sting out of the braking force — all of which reads as an improvement on the first pass. Then the hip that was already under-recruiting gets asked to do the same work at a higher turnover, and the calf that was compensating starts complaining instead.
What the plate usually shows is not a slow cadence but a late one: force peaking behind the centre of mass in the last third of a session. That is a strength problem wearing a cadence costume.
