Amanar – Paseka v Maroney

The private GymFever2012 group is discussing this.

An incredible difference in air time.

Maroney

Is it possible that the speed of the two .gifs is different?

Or is Maroney that much higher?

You cannot change the path of the centre of gravity after release.

Bross, Memmel – PBS Wilder

2005 World all-around champion Chellsie Memmel and six-time World medalist Rebecca Bross were featured in the Oct. 23 episode of NOVA on PBS.

The episode, titled “Making Stuff Wilder,” is in a four-part series about biologically inspired inventions and engineering. …

Don’t bother commenting on the painfully obvious Y axis confusion. The more ESPN notices gymnastics, the better.

When Hardy Fink added the Hecht back tuck into the FIG Men’s Code of Points, we thought it was impossible. Until Rhett Stinson at Taiso did one — easily — into the pit.

Jennie Finch throws like a girl

And struck out Albert Pujols in one demo. :-)

Jennie Lynn Finch … is a former American softball player who pitched for the USA national softball team and the Chicago Bandits. Jennie helped lead Team USA to the gold medal at the 2004 Summer Olympics and a silver medal at the 2008 Summer Olympics.

Time magazine described her as the most famous softball player in history. In 2010, Finch retired from softball to focus on her family. …

Finch was the most dominant and recognizable softball pitcher of her era …

This is very, very cool.

According to Mike Candrea, her coach at Arizona and through two Olympics,

“Jennie has transformed this sport, touched millions of young kids in many different ways – whether it’s fashion, whether it’s the way she plays the game – but through it all she’s been very humble.”

A Chicago Tribune editorial commented,

“She leaves with a spotless personal reputation, an intent to keep promoting softball, and the knowledge that she has inspired other girls and women who play for the love of the game.” …

crossing the legs twisting

In ice skating, it’s considered good technique.

Lizzy sends a link of some flying trapeze training.

Click PLAY or watch it on YouTube.

She crosses her legs in an attempt to increase speed of spin.

AND — more importantly — scissors on release to generate twist. (equal, opposite, concurrent reaction force … according to Newton)

She doesn’t consider “stacking the legs” a form break. Or bad technique.

Landing is a non-issue. Happily trapeze acrobats don’t have to “untilt” the twist, then STICK a landing on a hard surface.

Men’s All-around Finals

Uncle Tim:

Max Whitlock went for his harder pommel horse routine today (7.2 vs. 6.6), hoping to give himself more leverage against the leaders. The plan worked. He scored a 15.633, which was 0.225 better than his score in prelims.

Sam Mikulak schooled the boys on how to stick on floor. 15.366.

Sergio Sasaki and his teammate Arthur Oyakawa threw the hardest floor routines in the all-around finals. Sergio opened with a front double pike to barani, which he followed up with a back 1.5 to punch double front.

After watching Kohei hold an inverted hang for so long, I started paying attention to inverted hangs. Sergio Sasaki did 4 of them.

This, in my opinion, should receive a deduction for poor composition. According to the Code, “Contemporary gymnastic exercises are characterized by transitions between elements of swing and strength or the reverse.” An inverted hang isn’t an element of strength or swing. 14.600

Kohei landing

Based on the screenshot alone, what would you give this vault in execution?

A 9.333 in execution? Yeah, no, but that’s what Kohei Uchimura got.

I like Kohei a lot, but I also have to recognize the fact that Kohei bonus exists. At times, the Code of Points is more a suggestion rather than a rule.

… Final Results: 1. Kohei Uchimura, 91.990 2. Ryohei Kato, 90.032 3. Fabian Hambuechen, 89.332 4. Max Whitlock, 89.031 5. Sergio Sasaki, 88.959 6. Sam Mikulak 88.548 7. Daniel Purvis, 88.106 8. Andrey Likhovitskiy, 87.423 9. Lin Chaopan, 86.864 10. Zhou Shixiong, 86.631

There’s much, much more on – 2013 World Championships All-Around Recapped

I like how Uchimura lands. Chest low.

Good technique on landing SHOULD mean bringing all the massive impact forces to zero. He’s one of the best that ever lived at doing that. We should study the best of the best at landing, and start requiring that technique.

They land like cats.

Two of the worst landers in history: Sacramone and Legendre.
