Isometric Tension, Lysyl Oxidase, and Collagen in Mobility Training

Описание: A lot of ankle mobility work is taught as “get in and get out.” A few inches off the wall, touch the wall, heel down, foot straight, short foot. You get there, and you get out.

But if you post-test and there is “more motion,” Charlie Weingroff argues that this is not proof you created adaptations for mobility, because time under tension was not established.

The mechanism changes when you hold. If you perform wall drill or step-and-rotate and create substantial isometric tension in multiple directions, this is the stimulus associated with connective tissue development, including lysyl oxidase, decreased oxygen partial pressure, and the brain's transcription of alpha-pro-1 collagen.

From there, he connects improved movement to proprioceptive and mechanical effects, in which the brain recognizes “more elements” that constrain motion in other directions.

He also clarifies the point: these drills are not wrong. But it becomes an issue when the explanation is factually incorrect or inconsistent with the laws of biology and physics.

Finally, if the goal is to develop new tissue, a nutrition or supplementation strategy is also required, because the raw materials do not arise spontaneously.
