研究人员开发新方法分析体育运动中的全身协调性

研究人员开发了一种名为复希尔伯特主成分分析（CHPCA）的新方法，利用无标记3D姿态估算数据来分析体育运动中的全身协调性。该技术可自动分割运动阶段，并将分析扩展到身体表面网格顶点，将运动链表示为连续相位场。该框架揭示了以躯干为锚定的全局相位结构，并量化了准备和执行阶段之间的功能不对称性，从而弥合了运动的运动学和动力学描述。 AI

影响引入了生物力学和运动科学的新分析框架，有望改善表现评估和伤病预防。

排序理由这是一篇详细介绍运动数据分析新方法的学术论文。

Phase-Separated Complex Hilbert PCA on Markerless 3D Pose Estimation Data: A Global Phase Network and Its Extension to a Continuous Field on the Body Surface

Quantitative analysis of the kinematic chain in sports motion is essential for performance evaluation and injury prevention. Conventional methods such as the kinematic-sequence (KS) and continuous relative phase (CRP) are confined to adjacent joint pairs and lack a unified framew…
