This study aims to investigate the kinematic and kinetic characteristics of Duo Bu Zhuan, a representative rotational movement in Chinese Uyghur dance. As a fundamental movement pattern that reflects the rhythmic structure and stylistic features of Uyghur dance, Duo Bu Zhuan requires coordinated lower-limb force generation, balance control, and whole-body rotational momentum.
This research analyzes the movement from a biomechanical perspective, focusing on variables such as movement time, center of mass displacement and velocity, joint angles, trunk inclination and torsion angles, torque, and ground reaction force. By comparing the different phases of the movement, this study clarifies the mechanism of rotational power generation initiated by stomping and the coordination between the lower limbs, trunk, and whole body.
The results showed that Duo Bu Zhuan was performed through a sequential structure of preparation, rotation, and completion. The middle phases of the movement played an important role in center of mass transfer, rotational power generation, and body coordination. The center of mass showed changes in forward-backward, left-right, and vertical directions, indicating continuous balance control during rotation. Joint angle changes in the hip, knee, and ankle reflected the role of the lower limbs in supporting the body and controlling rotational movement. In addition, trunk inclination and torsion increased during the main rotational phases and decreased in the final phase, showing their contribution to rotational stability and movement control. Torque and ground reaction force were mainly observed during the execution phase, suggesting that stomping and supporting-leg force transmission are key factors in generating rotational momentum.
Furthermore, thefindings provide a scientific basis for understanding the biomechanical principles of Duo Bu Zhuan and can be applied to the development of systematic teaching programs and effective training methods for Uyghur dance. In particular, the results may help dancers improve balance control, rotational stability, force transmission, and movement efficiency. The biomechanical data obtained in this study can also serve as foundational material for future dance science research, AI-based motion analysis, and the systematic transmission of Uyghur dance movements. Therefore, this study is expected to contribute not only to improving the performance quality of Uyghur dance, but also to promoting the scientific and systematic development of ethnic dance education.
