Evidence summary
Biomechanical work frames Speed as a trajectory-optimization problem: vertical progress is the objective, while unnecessary lateral or wall-perpendicular motion can cost time. Individual beta can still differ because athletes trade geometric efficiency against force, reach and contact reliability.
3D motion research directly studies Speed movement, but detailed biomechanical datasets remain relatively small.
The movement optimization problem
The athlete must move approximately 15 metres upward while following a prescribed hold layout. Motion not contributing to useful ascent can represent lost efficiency, though lateral movement may still be required by route geometry or an athlete's body dimensions.
Center of mass
Tracking body or center-of-mass motion helps analysts move beyond counting holds. Two athletes can contact similar holds but follow different trajectories between them.
Why 3D matters
A front-view video captures vertical and lateral motion but can miss movement toward and away from the wall. Three-dimensional analysis shows why wall-perpendicular displacement belongs in the efficiency discussion.
No universal biomechanical beta
The shortest geometric path may demand a reach or force profile an athlete cannot reproduce reliably. Biomechanics should compare feasible strategies rather than declare one visual line universally correct.
Practical translation
Consistent video can track hip path, hold contacts, landmark times and positions at errors. These practical measures are simpler than laboratory motion capture but still useful for testing technique changes.
