Kendrick Ferris put together a great performance to set two U.S. records in the men's 85kg class. Ferris totalled 362kg and beat his own record in the clean and jerk with 202kg. Ferris ended up finishing 8th, but nonetheless, represented the U.S. very well in what has been typically an area of weakness for the U.S. in weightlifting.
An interesting note: Farris has changed his jerk technique from his 'odd' half-split/half-squat to a full-squat jerk. Obviously an improvement, but I have heard conflicting viewpoints on the full-squat jerk, which has been made popular by the Chinese and the legendary Pyrros Dimas.
Tyson Gay (10.05 semifinals, 5th) missed qualifying for the finals of the 100 meter dash. Not too sure if it would have mattered as both Asafa Powell (9.91 semifinals, 1st) and Usain Bolt (9.85 semifinals. 1st) have looked very good in the prelims. I think it is Bolt's race to lose. If he puts together a good start, I don't think anyone will be able to touch him.
A couple of interesting paragraphs from Mel Siff's Supertraining:
"The importance of ballistic activity to humankind recently has been shown to extend far beyond the realms of sport. Neurophysiologist, William Calvin, has proposed the fascinating hypothesis that the brain's planning of ballistic movements may have played a major role in the development of language, music and intelligence over the ages (Scientific American, Oct 1994). He makes this proposal, since ballistic movements and language processes involve some of the same regions of the brain, in particular those associated with sequencing and planning. In reaching this conclusion, he emphasizes that ballistic movements, unlike cocontractive slower movements, require a great amount of planning and problem solving. Slow movements may be corrected readily by ongoing feedback information, but ballistic movements require the brain to determine every detail of the action in advance by mentally planning the exact sequence of neural activation for numerous individual muscles.
Apparently, parts of the language cortex of the brain serve a far more generalised function than previously suspected. It is implicated in the production of novel sequences of sensations and movements for both the hands and mouth, so that ballistic arm actions may play a role in mental development. Calvin adds that improvements in language skills might improve dexterity and vice versa. The emphasis placed by Russian coaches on athletes being able to accurately describe, draw and visualise sporting movements woudl appear to correlate with this proposal. Instead of simply executing entertaning plyometric drills like biological robots, athletes would be wll advised to integrate cognitive processes mroe actively into the training programs."
