How Much Time For "Bounce Back"?

Left click on each image to enlarge. The larger structures within the dead bone image at left called "osteons" (the round, circular structures) seem made of material that is continuous and dense.

But increase the resolution and significant gaps with fibrils rooted at certain points seeming more suspended within spaces start to appear.

The Planck image at left represents banding and coating of individual bone collagen fibrils.

And the Hansma lab image above at 200 nm-quite small- shows dead fibrils coated with mineral bumps with a Velcro like appearance. Under pressure might these bumps given their chemical, physcial properties congeal together and hold like velcro.

Image below shows a dead bone slice, and we consider what may occur if we placed these fibrils in the palms of our hands and pressed them together, released, press, release and repeat 240 times.

Same deal with the Hansma illustration below.
The question after the race-- if we got some adherence (congealing) and alignment of these fibrils, what might be the time frame in which they would bounce back to their original positions? And, how is this to be determined?

Considering this, I believe some educated guess work is possible merely by considering the nature of the materials and how things happen within the nano-structures as previously discussed on the blog.

E.g. one of the immediate post race characteristics of cannon bones is "heat". Temps within the bone are extremely elevated, dissipate slowly, and, depending on conditioning and race exertion level there may be some heat even 48 hours post race. In view of this heat may we think that fibrils would be more likely to stay in adhered/aligned positions during this period of heat when they are less stiff, and that bounce back effect will accelerate when the bone cools.

The post race heat factor by itself permits thinking that bounce back will probably begin only after the expiration of 48 hours. Possibly by day 3 will see the bone material in full bounce back mode, and by day 4 perhaps bounce back will be on the way to completion.

Other consider this, next post.
