Dos Santos I

The Double Arabian Piked is a variation of the twist jump (popularly known as a spinning pirouette) followed by a double somersault. This move was first performed perfectly by Brazilian gymnast Daiane dos Santos. In the Portuguese language, it became known as duplo twist carpado. For this reason, it was given the name "Dos Santos".

History

In 2003, when she performed this move for the first time, Daiane won the gold medal in the floor exercise event at the Anaheim World Championships in the United States of America.

In 2007, American Alicia Sacramone included the same move in her routine. However, today Daiane is still the only athlete to perform the stretched double twist, which has a higher degree of difficulty and is listed in the Table of Elements as Dos Santos II.

Analysis

Brazilian gymnast Daiane dos Santos.

Technique

Listed below are the characteristics analyzed of the gymnast's movement, based on kinematic analyses of physics:

• Height: (maximum displacement of the center of gravity): 1.54 meters.
• Maximum height reached (with the feet during the first somersault): 2.77 meters.
• Distance covered horizontally: 1.30 meters.
• Duration: 1.07 seconds.
• Vertical speed of departure and arrival: 5.2 m/s or 19.7 km/h.
• Maximum rotation speed in the air: 900 degrees/second.

Biomechanics

Before the jump itself, the gymnast performs a series of movements during the run to gain speed in the horizontal direction (amount of linear movement) and amount of rotation (or amount of angular movement), since there is a pirouette (rotation) in the air. At the end of the run, a movement of great vertical speed is performed to gain momentum in this direction. During the movement, the center of gravity describes a parabolic trajectory acquired by the speed and exit angle at the moment of the start of the jump. One should jump as high as possible - in order to remain in the air for longer - to store a greater amount of angular movement and thus be able to perform the rotations of the acrobatics.
