# Stride Length

> Length of stride as percentage of athlete height.

## Technical Details

* **Variable Type:** Discrete Metric
* **Data Type:** Float
* **Units:** % of height
* **Column Name:** `stride_length`
* **Aggregation:** mean
* **Precision:** 0
* **Calculation:** Distance between the dominant ankle at initiation and the lead ankle at foot contact, normalized by height
* **Optimal Direction:** Higher is better

## Description

Stride length measures the length of the stride as a percentage of the athlete's height.
It is calculated as the distance between the dominant (drive-side) ankle position at initiation and the lead ankle position at foot contact, normalized by the athlete's estimated height.

## Use Cases

* Stride analysis
* Mechanics evaluation
