Ballet Jumps unipedal (Sissone) and bipedal (Assemble)

We investigated hip, knee, and ankle lateral rotations in turnout during three phases (preparation, flight, and landing) of two jumps with displacement in the fifth position: one unipodal, the Sissone Ouvert, and one bipodal, the Assemblé Dessus.

Twenty-eight pre-professional ballet dancers were analyzed, with 11.5 ± 3.1 years of classical ballet practice, 8.5 ± 11.5 hours of weekly training, and a passive hip lateral rotation (static turnout) of 54.5 ± 8.6 degrees. The dancers performed rhythmic jumps, and after laboratory adaptation, five valid jumps from the self-selected leg were recorded. Kinematics were captured using eight infrared cameras using the Plug-in-Gait marker protocol. The landing phase was identified through the vertical component of the ground reaction force.

The excel files present the peak of the lateral rotation, the Range of Motion of the rotation (ROM) of each joint angle in the transverse plane in each jump phase (P-preparation, F- fligth, L-landing) of two Jumps: Assemble and Sissone, separately. It also includes the instant of each angle peak for each jump.
