Fujitsu “Judging Support System”

Fujitsu will be working Worlds 2021, of course. Analyzing more routines for their database.

A webinar has been posted online:

FIG and Fujitsu to discuss AI “Judging Support System”

Watanabe speaks in English in the video. He’s really improved over the past few years.

He points out that other sports are using video analysis. Tennis and baseball, for example.

But judging support is only one goal of the project.

Steve Butcher details other uses.

Fujitsu expects all 10 Artistic apparatus to be ready for 2024. (Progress seems slow, to me.)

By end of 2022 the “Training Support System” should be ready. I’d love to have a chance to test that in the gym.

The very first use of computer video analysis should have been to display height and distance of a skill relative to the height of the athlete. Vault post flight, for example.

Fujitsu is doing a good job analyzing Ring strength holds, however. The system can do better than most FIG judges.

Personally, I’m disappointed in the graphics rendered by the software. It’s embarrassing that every representation has feet apart, for example.

I WISH Fujitsu could output something 1/10th as good as FB CURVES 3D GYM.

Emily Bischoff:

… Teaching our athletes to land correctly is one thing coaches can control in terms of injury prevention, whether it be to lessen the load on tendons and ligaments to prevent overuse injuries, or to minimize the risk of fluke injuries …

… the force upon landing be dissipated throughout as much of the body as much as possible …

… feet around shoulder width apart, which widens the base of support over which force is exerted. Knees should be in flexion (bent), tracking over the toes …

Promoting Safety in Gymnastics: Landings

Kohei – 2014 Floor

I’d argue Kohei Uchimura singled handedly reinvented how male gymnasts land.

Easily the best in the world in his prime, many emulated Kohei’s exaggerated technique.

I love it as he turned the science of safely reducing huge impact forces to zero into an art form.

At the same time WAG was foolishly deducting low chest position. Dangerous!

Of his many stuck routines over many years, Blythe chose this as one of her decade-defining routines.

‘shaping’ for layout backward

Backward “gainer” drills are great for many reasons. Including the hip action on takeoff and shape for a hollow layout.

Chellsie Memmell, by coincidence, is an ideal model at the beginning of this video tutorial.

‘SET’ drill for rotation

Love it.

Click PLAY or watch it on Facebook.

Opening the hips on take-off generates backwards rotation. That’s an indirect reaction force that some beginners struggle to master.

Many beginners RUSH into the salto position before finishing the spring.
