Technical Details
- Variable Type: Movement Flag
- Data Type: Integer
- Units: N/A
- Column Name:
landing_phase_excessive_forward_drift - Optimal Direction: Lower is better
- Unknown Value: -1
- Measurement: Forward (fore/aft) body displacement between Apex and Termination, normalized by athlete height
- Threshold: Forward displacement greater than 50% of height
Description
Landing phase excessive forward drift is a binary indicator that flags if the body moves forward (into the court, in the serve direction) by more than 50% of the athlete’s height directly after the serve. This can indicate a lack of balance and control on landing.Use Cases
- Landing balance and control assessment
- Injury risk identification
