landing_phase_excessive_forward_lean - Optimal Direction: Lower is better
- Unknown Value: -1
- Measurement: Trunk forward flexion at Termination
- Threshold: Trunk flexion greater than 60° past vertical
Description
Landing phase excessive forward lean is a binary indicator that flags if the trunk leans forward more than 60° at the finish of the serve. This can indicate lack of deceleration control, increased strain through the low back, and poor positioning to prepare for a return volley.Use Cases
- Follow-through and deceleration assessment
- Injury risk identification
