Technical Details
- Variable Type: Discrete Metric
- Data Type: Float
- Units: × height (ratio to athlete height)
- Column Name:
displacement_open_side - Measurement: Open-side (lateral, non-dominant side) body displacement between Apex (ball contact) and Termination, divided by athlete height
Description
Open-side displacement (normalized) measures how far the body drifts laterally toward the non-dominant (open) side between ball contact and the finish of the serve, expressed as a multiple of the athlete’s height. It provides the underlying continuous measurement behind the Landing Phase Excessive Side Drift movement flag, which flags displacement greater than 0.30x height (or less than -0.10x height).Use Cases
- Lateral stability analysis
- Related to Landing Phase Excessive Side Drift flag
- Balance and follow-through assessment
