Reviewing on Sat.

Probably some races I should be paying attention to. Maybe this one, lol. Where the $8000.00 KEE fall yearling wins the $100,000 race, at Keenland. And the place goes to a $10,000.00 stud fee. A lesson, perhaps?
I am to the Jan. 2010 posts. Rereading the training. Good grief. In nice weather--the determination to train through anything. Then, bad weather does arrive, as we knew it would, and airborne ranger stuff drains away/ when training becomes impossible. On 1/15/10 we'd had 2 dry days at the farm since 11/1/09.
Jan. 2010 concerned the Max Planck articles. Having trouble right now recalling difference between a collagen molecule and collagen fibril. Supposedly the molecules make up the fibrils. Am failing to see that in the illustrations. Probably a minor worry.
#1 Planck indicates the important tie between mineralization, the quality of internal and external fibril mineralization and strength of bone tissue. Crucial! Involved in this is the "orientation" and arrangement of the materials.
Does exercise increase the density of the mineral platelets? Yes, but only to a certain point. Why? The mineral platelets both inside and outside the collagen fibril maintain a 40mm spacing between themselves. Thus, increases in mineralization goes only so far. Essentially, after all the interfibrillar spaces are filled, that's it in terms of density.
By Planck we calculate the "stiffness tensor" of a bundle of mineralized collagen fibrils.
What stimulates mineralization, by Planck, is yet unknown. Nice summary of Planck here:
Training:
Thurs: 1/14: off
Fri: 1/15: Brisk weather. Off yesterday. And, sure enough, they see me coming to get 'em in, and they take off. 20 min. to finally corral them leaves too little light for tack work. We do get in a very fast/too fast and hard riderless work--4 x 4f at 90-95% speed. This is too much for the state off training. Mistake by the trainer. Never exceed....(!)
