# Study 000G: The Cadence Protection Hypothesis

## Core Question

Is cadence the preserved control variable in this altered-mechanics running archive, and does stride become the more sacrificial expression variable when stabilization demand rises? If so, why does cadence preservation fail to fully protect internal burden?

## Answer

The archive supports that model. Cadence behaved like the more preservable running control variable, stride behaved like the more sacrificial expression variable, and cadence preservation alone did not guarantee low burden.

## Thesis

`Cadence protection appears to be one mechanism that helps maintain successful running expression within the operating envelope, but envelope support still modulates whether that mechanically preserved pattern remains physiologically tolerable.`
