# Peak Arm Angular Velocity

> The instant of upper arm peak angular velocity.

## Technical Details

* **Variable Type:** Event
* **Data Type:** Integer
* **Units:** Frame number
* **Column Name:** `peak_arm_velocity_frame`
* **Required for QA:** False
* **Measurement:** Peak angular velocity (deg/s) of upper arm segment

## Description

This event identifies the moment when the upper arm reaches its maximum angular velocity during the pitch, representing the peak of the arm kinetic energy.

## Use Cases

* Upper body mechanics assessment
* Peak velocity timing
* Pitch sequence evaluation
