landing_phase_excessive_side_lean - Optimal Direction: Lower is better
- Unknown Value: -1
- Measurement: Trunk lateral (side-to-side) tilt at Termination
- Threshold: Absolute trunk tilt greater than 30° (to either side)
Description
Landing phase excessive side lean is a binary indicator that flags if the trunk is tilted sideways more than 30° (in either direction) at the finish of the serve. This can indicate poor deceleration control, increased lateral low back strain, and poor positioning to prepare for a return volley.Use Cases
- Follow-through and deceleration assessment
- Injury risk identification
