# Peak Pelvis Angular Velocity

> The instant of pelvis peak angular velocity.

## Technical Details

* **Variable Type:** Event
* **Data Type:** Integer
* **Units:** Frame number
* **Column Name:** `peak_pelvis_velocity_frame`
* **Peak Detection Parameters:**
  * Minimum height: 250 deg/s
  * Minimum prominence: 250 deg/s
  * Distance to next peak: 24 frames (0.1 s)
  * Minimum width: 0.1 s (24 frames)

## Description

This event identifies the moment when the pelvis reaches its maximum angular velocity during the swing, representing the peak of the lower body kinetic energy.

## Use Cases

* Pelvis power analysis
* Lower body mechanics assessment
* Peak velocity timing
* Swing sequence evaluation
