R.I.P. Dr. Gerald S. George

The man who personally defined Gymnastics technique for me has died. Dr. Gerald S. George.

Rest in peace.

When his 1979 text book was published — Biomechanics of Women’s Gymnastics — I bought 10 copies and handed them out to our competitive staff.

He updated it 2010 in an edition called Championship Gymnastics.

BEST of all are the illustrations by James H. Stephenson.

Neither book was focused on biomechanics. Most groundbreaking was his taxonomy of how to define good technique. Any future computerized analysis should use these principles.

 Movement-Refining Principles

1. Amplitude Principle

A. External Amplitude
B. Internal Amplitude

2. Segmentation Principle
3. Closure Principle
4. Peaking Principle
5. Diversification Principle

Flyaway to Flat Back

BEFORE we let kids flip, it’s essential that they understand well how to move the centre of gravity AWAY from the Bar at the point of release.

Some call it “pitching out” the centre of gravity.

Flyaway not Flyclose.

video skills with 4 cameras simultaneously

One exciting update to the NEW iPad Pro announced yesterday is this feature called Live Multicam.

It could make video analysis of skills faster and easier.

FB-Curves 3D GYM apps for coaches

By site editor Rick McCharles.

For the first time I have the full paid version of the FB-Curves 3D GYM apps.

Fantastic.

There’s nothing else out there even close to what this software offers.

I lot in via the webpage, rather than the app. This way I have a bigger image on my display.

Best use for me is showing gymnasts a skill from multiple angles.
