Putting a sponge between the feet is an ideal way to remind gymnasts to squeeze the legs together.
MLT likes the gymnast to hollow — then pike — to slow the down swing for the next kip. Of course hip flexion and/or shoulder extension would accomplish the same thing. The hollow position is an aesthetic preference.
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.
