Technical Details

  • Variable Type: Discrete Metric
  • Data Type: Float
  • Units: degrees/s
  • Column Name: Varies by phase (see Events/Phases); left/right in bilateral, single value in single-leg
  • Measurement: Maximum rate of hip extension during the specified concentric phase

​
Events / Phases

This metric can be reported during the following concentric phases:
  • Takeoff Concentric: From Bottom to Takeoff.
    • Maximum hip extension velocity during the propulsive jumping phase.
    • Column examples: jumping_left_hip_peak_extension_velocity, jumping_right_hip_peak_extension_velocity (bilateral); jumping_hip_peak_extension_velocity (single-leg).
  • Landing Concentric: From Landing Bottom to Termination.
    • Maximum hip extension velocity during the return to stand after landing.
    • Column names vary by implementation; left/right in bilateral.

​
Description

Peak hip extension velocity is the maximum angular velocity of hip extension during a concentric phase—either the push phase of the jump (takeoff concentric) or the stand-up phase after landing (landing concentric). It is a key contributor to jump performance and reflects hip power. The phase determines which column name applies.

​
Use Cases

  • Hip power and contribution to jump or stand-up
  • Kinematic sequence (proximal-to-distal)
  • Bilateral or single-leg comparison
