What is summersault?

As an AI language model, I am assuming you meant to ask about the specific term "somersault."

A somersault is a physical movement where a person flips forward or backward in a complete rotation, usually landing back on their feet (in a forward somersault) or on their back (in a backward somersault). It is a common acrobatic move often seen in gymnastics, diving, and other similar sports.

The term "somersault" comes from the French word "sommerset," which translates to "overturning." It was first recorded in English in the 16th century.

There are different variations of the somersault, including the tuck, layout, and pike. In a tuck somersault, the person curls their body into a ball, while in a layout, they keep their body straight throughout the rotation. In a pike, the person folds their body in half at the waist, keeping their legs straight.

Performing a somersault requires a lot of practice, control, and strength. It can also be dangerous if not executed correctly, as it puts a lot of pressure on the neck and spine. Therefore, it's always important to practice under the supervision of a trained instructor.
