Biomechanical Analysis on the Technical Movements of Yajia Sport
Yajia,a traditional competitive sport of ethnic groups,currently lacks standardized and scientifically guided teaching and training methods,with each ethnic region employing distinct techniques.This study delves into the technical movements of Yajia sport,specifically focusing on the lower limb joints from a biomechanical standpoint.Joint coordinate systems were established,and equations for articulating forces and torques at the hip and knee joints were computed.The Yajia model adopted a modeling approach that combines the Lagrangian method with the Hill muscle model.The numerical calculation equations for dynamic parameters were elucidated,analyzing the torque magnitude of hip and knee joints concerning potential energy angles within the Yajia sport system.The study found a direct correlation,indicating that as the angle of the hip joint increases on the coronal axis,the resultant force also increases,providing a biomechanical advantage for Yajia sport.Establishing a dynamic model for lower limb joints in Yajia contributes valuable scientific theoretical guidance to the sport.
