Gymnastics – 3D laser sensors?

This looks interesting.

2016 The Japan Gymnastics Association, Fujitsu Limited, and Fujitsu Laboratories Ltd. today announced an agreement to conduct joint research on scoring support technology for gymnastics competitions. This research will combine Fujitsu Laboratories’ 3D laser sensors and 3D data processing technology–to discern athlete’s joint position and technique–with the Japan Gymnastics Association’s expertise in recognizing proper gymnastics techniques. …

Gymnastics – safest landing positions

Dr. Dave Tilley is concerned:

… the unfortunate reality is that the typical way gymnasts were taught to land growing up (me included) may not be the safest for them and most effective to stick skills. Not to mention coaches are also unfortunately very mis-informed about what the best available science suggests for proper landing mechanics. The concerning typical landing position that we need to move away from is one of

• Knees and feet together
• Glutes engage with the “hips tucked under” into hollow
• Knee dominant landing strategy
• Stiff impact with upright torso

… The reality of the situation is that we need to change the way gymnasts land, starting from a very young age. The more ideal landing we should be teaching and forcing athletes to use is

• Feet hip width apart
• toes, knees, hips, and shoulders close to inline (generally)
• core engaged in relative neutral (not excessively hollowed or arched)
• proper angular displacement of the hip and knee joints
• hip angle generally 30 degrees, and trunk / tibial lines close to parallel …

Why Gymnasts Must Change How They Land

With greatly increased difficulty being competed now and into the future, obviously the “best” landing positions are the ones that bring impact forces to zero with the least risk of injury, especially major injuries like ligament ruptures.

Most of the top male gymnasts in 2016 land their difficult skills in a very typical way.

Check these successful WAG landing positions. (Some are luck, of course. But many are skillful.)

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. …

new G.S. George Gymnastics manual

Greg Marsden has been talking up George’s first new book in decades. It’s finally here.

Hardcover Textbook, 11 1/4″ x 8 5/8″
280 pages, Copyright April 2010

You can pre-order online … or call 888-796-5229.

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. …
