| Resumé≠ | 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. | The force-velocity profile characterizes an individual's mechanical properties across the force-velocity spectrum, revealing whether strength advantage lies in maximal force production or high-velocity power output. Formalized by Samozino and colleagues (2012), the FVP is derived from multiple load-velocity measurements (typically sprint starts, jumps, or push-off movements at various resistances) and mathematically modeled as a linear inverse relationship between force and velocity, anchored by maximal power. Athletes differ markedly in their FVP: some excel at moving heavy loads slowly (force-dominant), while others excel at moving light loads fast (velocity-dominant). Profiling identifies these phenotypes and informs targeted training interventions. |
