Technical Details

  • Variable Type: Event
  • Data Type: Integer
  • Units: Frame number
  • Column Name: bottom_of_landing_frame
  • Required for QA: False
  • Measurement: Lowest pelvis height during the landing eccentric phase

​
Description

Landing bottom marks the instant when the pelvis reaches its lowest point during the landing absorption (eccentric) phase. This event separates landing eccentric from landing concentric (stand-up) phase.

​
Use Cases

  • Landing eccentric vs. concentric phase definition
  • Landing stiffness and absorption metrics
  • Knee valgus at landing bottom
