I’m not sure what all this means, but scientists are pretty excited right now. 🙂

For gymnasts, gravity still sucks.

G.S. George – “Accelerating the Rotation”
Close your eyes while coaching tumbling. Can you hear the acceleration?
See this article excerpted from Championship Gymnastics and edited by Dwight Normile of International Gymnast Magazine.
G.S. George – Somersault Rotation
While rotating in the air, the more you bring body parts closer to the axis, the faster you spin.
See this article excerpted from Championship Gymnastics and edited by Dwight Normile of International Gymnast Magazine.
To decelerate, move parts of the body further from the axis.

A sample — “The Mechanics of Impact“:
… The effectiveness of the take-off sets the uppermost limits of what the gymnast can hope to obtain during the airborne phase of any skill. During this moment, the path (trajectory) followed by the performer’s center of gravity, as well as the quantity of rotary motion (angular momentum) available for skill execution, are irrevocably established. …
Once the gun has been fired, there is no turning back…for the trajectory and momentum of its bullet are irrevocably established! …

George is the author of Biomechanics of Women’s Gymnastics (1980), one of most important coaching texts of all time. This is the follow-up.
Championship Gymnastics represents an entirely new approach to the study and understanding of gymnastics movement. …
Rather than laboring on complex physics formulas, fundamental principles of biomechanics are clearly explained and presented in layman’s terms. Easy to read and expertly illustrated, readers are guided effortlessly through a “conceptualization process” for developing ideal movement patterns. The book includes 140 technical illustrations by noted artist and gymnastics coach Jim Stephenson. Gymnastics skills are described clearly and illustrated progressively to demonstrate that “similarities” in gymnastics movement patterns far outweigh “differences.” As a result, seemingly complex gymnastics skills are reduced to simple, easy-to-understand patterns of motion. …
See the table of contents.
Looks great. Especially the illustrations.
On the other hand, George seems to have been spending more time as “expert witness” in gymnastics court cases than in the gym. Has he still got it?
Leave a comment if you determine the price. It’s buried somewhere. $79. OUCH. No wonder the damage was hidden. ($60 if you order more than ten.) Thanks JAO.
coming soon – new G.S. George book
Greg Marsden tweeted this news:
Read the intro to “Concepts in Women’s Gymnastics” by Dr. Jerry George, illustrated by Jim Stephenson. It will be a must read for all coaches and gymnasts.
Dr. Gerald S. George, author of the excellent “Biomechanics of Women’s Gymnastics” (1979), is finally publishing another. Gymnastics coaching books are rare, as you know.
Here’s confirmation:
… have just completed a new textbook entitled “Concepts of Women’s Gymnastics” which will be available to the public in January 2010. …
