Research Scope
Footwork neural control, split-step reactivity, kinetic chaining, and lower-body force transmission — how the nervous system orchestrates elite movement patterns.
Key Themes
- Split-step timing and reactive neural pathways
- Kinetic chain initiation from ground contact
- Proprioceptive feedback loops in dynamic movement
Grounded Insights
- The split-step activates 120-150ms before opponent contact, pre-loading the stretch-shortening cycle
- Ground reaction force vectors travel from foot > ankle > knee > hip in 15-20ms chain
- Elite players show 40% greater proprioceptive acuity in ankle joints compared to sub-elite
- Elite players show 40% greater proprioceptive acuity in ankle joints compared to sub-elite
