Perspective on Bone Cells During The Breeze

The last days I've read the news instead of posting. What a distraction the Internet these days and all these Democrats or Dumocrats as my old Uncle delights to refer. Sometime before the election an RR political post coming.

But, horses and bone cells.

I love those You Tube Overdose(OD) videos and keep watching them over and over. Nice example to shoot for in your training, and, for here, to imagine what occurs to the OD bone cell motoring down the track.

You may left click to enlarge the dead cell images here that, were they live images from a moving OD, probably would be a bit more bloated and filled out instead of dead, dried out and contracted. We must project a bit as to what these would look like alive!

Does this material hold up both in single stride and with repeated concussion? Interject again here as you watch any race and focus your eyes on that front lead the lack of concern watching a single stride compared to how one's concern increases psychologically with repeat after repeat. Watch one and notice how you start to worry as the race goes on.

Another way to ask the question is whether the material remains static or whether there's any movement such as that postulated in the recent prior posts. I conclude there is indeed some movement with each strike, but we consdier the variables of this:

-nature of the material--organic, inorganic mineral matrix, collagen
-position of the cell within the whole bone
-direction, nature and quantity of force

and, extremely significant-- though probably at the tiniest microscopic level in our conceptions there IS movement of material, what really is the difference in practical terms between e.g. a 1nn (or less) distance of movement and the material remaining static??? Consider that electrons are spinning in every atom of our bodies at all times as a comparison. We might say there can be microscopic movement without any effect--almost.

We can say that there is "almost" zero practical effect from movement, rearrangement, gliding, sliding, expansion and contraction of bone cell material until we consider the phenomena of the "repeated blows." I'm imagining that with a single stride of a horse the quantity and significance of bone cell movement is almost nil, BUT as that along with the level of our own psychological concern as we watch repeated strides there is indeed something happening in real time at the bone cell level with repeated strikes.

What happens (for purpose of this blog) I'll describe as "loosening". I'll take the wild guess that the various materials simply fail to rebound completely within each stride although I'd suspect the amount of rebound after any single stride is at least close to complete. But, then we get less and less rebound with each succeeding stride until (possibly) after 60 strides on that lead the material is ever so slightly microscopically separated (or rearranged) from where began.

BUT, we take note, then the horse is off that lead and for the next 60 strides onto the other lead. Hence in our "strikes" on the bone cell, we have 60 strikes followed by a 60 stride pause. I'm thinking that this pause, probably gives the material time to nearly completely rebound before the next cycle commences.

Thus, this post postulates within the bone material some "movement" during the breeze, but movement over so small a distance that there's little difference to the material remaining static, though this relationship weakens as the horse continues to stride.

Hopefully I've hit here somewhat on what's actually happening. What may we conclude will follow.

Training:
Sun: 8/24: after yesterday's fast riderless Art trots a mile with a bit of gallop, tack. Rod is off with his healing mouth.
Mon. 8/25: Art under tack trot-gallops 1.25 miles, about 1/2 of it gallop. Rod walks under tack for 5 min. Both horse then do about 10 min. of riderless work at medium gallop.
Tues. 8/26: Off. Our trainer is awol today.
Wed. 8/27: Art tacks a 1 mile trot-gallop without about 3/4 of it gallop. Art has now galloped most of the .8 mile course but we've still yet to negotiate a couple of the difficult sections with gullies, and, leads continue to be a problem. Nob fails a lead change, and I remind, think Georgie Boy. RR Rule--fail to get the lead change, abort.
