## Description

Peak trunk angular velocity measures the maximum angular velocity (twist speed) of the trunk segment during the pitch, indicating the peak rotational speed of the core.

## Normative Ranges

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