Link Segment Inverse Dynamics
Inverse dynamics is a biomechanical analysis technique that calculates joint moments (forces and torques) from measured kinematics (positions and angles) and ground reaction forces. Formalized by David Winter (1990), inverse dynamics works backward from Newton's second law: given acceleration and inertia, calculate the net force (or moment) required to produce that motion. By analyzing joint loading during sport movements, biomechanists identify asymmetries, technique flaws, and muscle-group imbalances that predict injury or limit performance. Inverse dynamics is the standard for detailed biomechanical assessment in research and elite coaching.
