Time-Series Deep Learning Modeling of Technical Rhythm in Wushu Athletes
This study introduces a novel deep learning approach for quantitative analysis of Wushu movement rhythm, leveraging Inertial Measurement Units (IMU) data. The proposed Spatio-Temporal Attention Long Short-Term Memory (ST-LSTM) model achieves high accuracy in rhythm classification (94.237%) and excellent correlation in scoring prediction (0.912 Pearson coefficient), significantly outperforming traditional methods. This offers a robust, data-driven solution for objective assessment and scientific training in Wushu, addressing limitations of subjective expert evaluation.
