> Pelvis rotation angle relative to home plate at ball release.

## Technical Details

* **Variable Type:** Discrete Metric
* **Data Type:** Float
* **Units:** °
* **Column Name:** `pelvis_angle_to_plate_release`
* **Aggregation:** mean
* **Precision:** 0
* **Measurement:** Pelvis rotation (twist or transverse) angle at ball release
* **Reference:** 0° = facing home plate
* **Timing:** At ball release event
* **Typical Range:** 11 – 25 °
* **Optimal Direction:** Middle — moderate values are optimal

## Description

Pelvis angle to plate release measures the pelvis rotation angle relative to home plate at the instant of ball release, where facing home plate is 0 degrees.

## Normative Ranges

Percentile distributions by competition level from the 2026 Q1 dataset; the optimal range spans the 25th–75th percentiles.
