Dataset of Ballet Jumping Experiment
Description
The experiment involved thirteen healthy young participants (12 females and one male) with a mean age of 21 ± 8.4 years, height 161 ± 13 cm, and weight 46.4 ± 17.3 kg. Participants were divided into three groups based on age and ballet dancing experience: an amateur group (students with varying levels of ballet expertise), a professional group (professional ballet dancers in a ballet company), and a children's group (children from a local ballet school with ballet experience ranging from good to basic).
Participants were selected based on the following criteria: having ballet experience from basic to advanced levels, no lower limb injuries in the past six months, and the ability to perform repeated jumps without excessive fatigue. Participants with musculoskeletal disorders were excluded. The study was approved by the Ethical Committee of TU Darmstadt (EK 47/2021) in accordance with the Declaration of Helsinki, and all participants provided written informed consent before participation.
Initially, participants were instructed to perform three consecutive Sauté en suite jumps using their previously learned technique. They were then given an external focus of attention cue: "Take the whole floor with you." This instruction aimed to direct the dancers' attention toward the external effect of movement, which was expected to enhance performance by increasing jump height and improving body axis stability. After receiving the instruction, participants repeated the three jumps.
Motion tracking was conducted using 36 reflective markers placed on specific anatomical locations, captured by an infrared camera system (Qualisys, 460 Hz, Sweden). Ground reaction force (GRF) and center of pressure (CoP) data were collected for both legs using one Kistler force plate (1 kHz, Switzerland). These data were processed using OpenSim's inverse kinematics and dynamics tools. To calculate rest length and stiffness, the Spring-Loaded Inverted Pendulum (SLIP) model is used. For data analysis, 3 jumps were selected per participant.
