# Shin Angle at Loading

> Max forward shin angle during the loading phase of the pitch.

## Technical Details

* **Variable Type:** Discrete Metric
* **Data Type:** Float
* **Units:** deg
* **Column Name:** `shin_angle_at_loading`
* **Aggregation:** mean
* **Precision:** 0
* **Measurement:** Max forward lean of the loading-leg shin segment relative to vertical
* **Timing:** Between initiation and high hand events
* **Optimal Direction:** Middle — moderate values are optimal

## Description

Shin angle at loading measures the maximum forward lean of the loading (dominant-side) shin relative to vertical during the loading phase of the pitch, between initiation and high hand.

## Use Cases

* Loading phase assessment
* Mechanics evaluation
