Sun. Review

Expensive horses do win an occasional race--see yesterday's Canadian International. After what they did to George Washington, I decline congratulating those connections on anything. And, John Shirref's horse Harmonious wins in KY. What a surprise! I forgot to put down a couple of bucks at Twin Spires in my late "sure thing only" betting mode.

On to Feb. 2010 review where early in the month there appear some nice bone posts, if I may say so. Possibly the most significant research for our purposes--on 6/09 Hansma Lab is exercising mice on a treadmill from 21 days to 4 months and measuring bone strength between various groups, including sedentary control groups, with their new bone indentation instrument. This instrument measures bone strength. Their discovery? Within 21 days of the onset of exercise there are significant increases in bone strength in the younger mice, i.e. mineralization changes!

After Hansma above in a general sense then, we understand exercise will affect mineralization in youngsters within 21 days of inception. We await further studies for particular measurements of the various and differing indices of bone strength--i.e. specifics yet to come.

At any rate, the February posts are zeroing in on orientation, spacing, rearrangement at the nano level as the primary qualities that strengthen exercised bone. Note also that increases in mineralization of mature bone might mostly involve increases in the number of HA crystals within single fibrils, as opposed to any increase in the number of fibrils, fibril arrays, or osteons.

Training: rereading our terrible last winter. Thought processes for coming training being readjusted. Trip to St. Louis soon!
