# Peak Trunk Angular Velocity

> Max angular velocity of the trunk segment during the swing. This represents the peak power generation from the core.

## Technical Details

* **Variable Type:** Discrete Metric
* **Data Type:** Float
* **Units:** °/s
* **Column Name:** `peak_trunk_angular_velocity`
* **Aggregation:** mean
* **Precision:** 0
* **Measurement:** Maximum trunk angular velocity
* **Phase:** Core power generation
* **Optimal Direction:** Higher is better

## Description

Peak trunk angular velocity measures the maximum rotational speed of the trunk during the swing, representing the peak power generation from the core segment.
The timing of peak trunk 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.
