Shrnutí:In the domain of martial arts pedagogy and athletic conditioning, accurately capturing biomechanical movement patterns is vital for individualized feedback and injury prevention. With the evolution of micro-electromechanical systems (MEMS), wearable sensor arrays have become increasingly compact, efficient, and suitable for long-duration, unobtrusive motion tracking. In this study, a wearable lower-limb monitoring system is introduced, which integrates tri-axial inertial sensing modules comprising accelerometric, gyroscopic, and magnetometric units. To enhance the reliability of multi-modal kinematic signals, an adaptive fusion framework is constructed, incorporating quaternion-based orientation estimation and magnetic field calibration via ellipsoid compensation techniques. This system enables the extraction of joint kinematic parameters and supports the development of a comprehensive dataset tailored to martial arts biomechanics. Building upon this dataset, a regression-based predictive model is trained to quantify technical execution quality and estimate susceptibility to musculoskeletal strain. The resulting system facilitates decision-making in instructional contexts by offering interpretable, data-driven insights that inform skill refinement and safety interventions.
