# Peak Arm Angular Velocity

> Max angular velocity of the lead upper arm segment during the swing. This represents the peak power generation from the arms.

## Technical Details

* **Variable Type:** Discrete Metric
* **Data Type:** Float
* **Units:** °/s
* **Column Name:** `peak_arm_angular_velocity`
* **Aggregation:** mean
* **Precision:** 0
* **Measurement:** Max lead upper arm angular velocity
* **Optimal Direction:** Higher is better

## Description

Peak arm angular velocity measures the maximum rotational speed (deg/s) of the lead upper arm during the swing, representing the peak power generation from the upper arm segment.
The timing of peak arm angular velocity determines kinematic sequence in part.

## Normative Ranges

Percentile distributions by competition level from the 2026 Q1 dataset; the optimal range spans the 75th–90th percentiles.
