RHETT ALLAIN is an Associate Professor of Physics at Southeastern Louisiana University.
In Wired magazine he tries to explain two saltos, three twists in 1.18 seconds.

Simone & MyKayla – Amanar
We really need computer video analysis for judges on Vault. Height of centre of mass relative to height of the gymnast.
Heart this. Simone is HIGH.
Recall the Maroney & Uchimura comparison?
McKayla might be even higher than Simone.

Reality check – Kohei has said that his goal is sticking the landing. For tumbling and vault he does not try for his maximum height. Instead, he wants optimum height.
Simone seems to hang in mid-air
Physics … meh. 🙂

FIG wants to scan gymnasts at Jr Worlds
Luba found this on the workplan for Junior Worlds on the FIG website.
Certainly that data would have to be kept confidential.
Fujitsu “judging support system” at Worlds 2019
The system uses 3D laser scanner sensors to capture the gymnasts’ movements in real time, providing two million shots per second on areas such as arm or leg bend angles, angles of elevation and height of particular moves.
This is then compared to a database of existing recognised moves and routines to hopefully provide a more accurate picture of an athlete’s routine for the judges. …
The technology is now planned to be deployed at the forthcoming Artistic Gymnastics World Championships, held from October 4th-13th in Stuttgart, Germany, with further tests planned as Fujtisu aims to get it included at Tokyo 2020.
GymCastic reported that FIG plans to test the technology on 2 WAG apparatus, 3 MAG apparatus in Stuttgart.

Baseball’s hitting coaches are geeks
By the numbers: 19 of MLB’s 30 hitting coaches played less than 100 big league games, 13 never played in the majors and four never even played in the minors.
All but four were hired in September 2016 or later, proving just how much fresh blood has entered a once insular community of former batting champions….
‘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.
tumbling / Slinky analogy
I can go with this.
It’s similar to the ‘curvilinear action‘ still used in the Canadian coach education system. That was introduced by Gord Osbourne and Boris Verkhovsky back in the day. That version looks at the body more as a flexible rod … with a spring attached to either end.
