Reaction, Disturbance, Distance And Bones

My term, bone disturbance describes what I imagine happens in the bones as the horse gallops down the track. As noted last post, I believe this to be a cascading series of events.

Consider:

1. Dilation of blood vessels in response to appropriate warm up and exercise as the nitric oxide mechanisms kick in.
2. Increased nerve activity signaling what occurs.
3. Increasing movement at all levels, atomic, cellular, structural, causing:
4. Heat build up (feel the cannons after a race).
5. Tightening and gradual lengthening of various bonding material including sacrificial bonds.
6. Crunching of microscopic non-living mineralized lattice here and there.
7. Micro-fissures developing on the bone surface and, with enough force, bone interior.
8. Loosening of microscopic living and non-living specs of calcium and other mineralized matter within the spaces of the bone matrix.
9. Anything else RR has overlooked at the moment.

I am supposing that the most significant effect involves the sacrificial bonds illustrated below

As noted in my posts on warm up they are just recently discovering with aid of electron microscope images that there is a "glue" in the bone involving living tissue that acts as the "sacrificial" bond illustrated which is stronger than mere contact because the bonding gradually lets itself out in response to force.

I am supposing that possibly in response to enervation within the bone tissue that initially these bonds tighten and the force as you go causes the bonds to lengthen and then with enough force finally break.

Given these various effects, all of which I believe will cause the later remodeling after the work is completed, the question becomes where are we in the various processes at any point on the track. Our question remains, at what point is there enough activity to cause the later remodeling that we want, next post.

Training: I'm shortly off to the farm. Great weather before the next polar bear stuff blows in tonight.
