The “Tsukahara” is a skill in which sport?

The Tsukahara can refer to a specific vault and a family of vaults in artistic gymnastics. In Japanese, this technique is known as a "Moonsault".

A Tsukahara vault consists of a half turn off the springboard onto the vault table, then a push backwards, usually into a back salto or layout.

Any vault that has a handspring with 1/4 - 1/2 turn onto the vault table into a salto backwards is classified as a Tsukahara vault. Some variations on the Tsukahara vaults include:

Kim - Tsukahara tucked or stretched with full twist (360°) off

Zamolodchikova - Tsukahara stretched with a 2/1 turn (720°) off

Phelps - a half turn onto the vault table, followed by a half turn off and into a front layout.

The first Tsukahara vault was performed by (and named after) Mitsuo Tsukahara in 1972.

Mitsuo Tsukahara (born December 22, 1947) is a Japanese artistic gymnast. He was five times an Olympic Gold Medalist. He remained active in the sport after his retirement from competition. He served as vice president of the Japan Gymnastic Association.
