Technical Details

  • Variable Type: Movement Flag
  • Data Type: Integer
  • Units: N/A
  • Column Name: landing_phase_excessive_side_drift
  • Optimal Direction: Lower is better
  • Unknown Value: -1
  • Measurement: Displacement Open Side Per Height between Apex and Termination, normalized by athlete height
  • Threshold: Open-side displacement greater than 0.30x height, or less than -0.10x height

​
Description

Landing phase excessive side drift is a binary indicator that flags if the body moves too far toward the open side (or too far toward the opposite side) after the serve. This can indicate a lack of balance and control on landing.

Use Cases

  • Landing balance and control assessment
  • Injury risk identification
