# Relative Hand Position - Away from Body

> Distance along the axis forward away from the body (+) between mid-shoulders and the average of the two wrists at the foot contact event.

## Technical Details

* **Variable Type:** Discrete Metric
* **Data Type:** Float
* **Units:** raw: m, display: in
* **Column Name:** `relative_hand_position_away_from_body`
* **Aggregation:** mean
* **Precision:** 1
* **Measurement:** Lateral distance from mid-shoulders to average wrist position
* **Direction:** Away from body (+)
* **Timing:** At foot contact event
* **Typical Range:** 3.3 – 7.1 in
* **Optimal Direction:** Middle — moderate values are optimal

## Description

Relative hand position away from body measures the fore/aft position of the hands relative to the shoulders at foot contact, indicating pre-swing hand positioning.

## Normative Ranges

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

| Population         | Optimal Range (25th–75th) | 10th | 25th | 50th | 75th | 90th |
| ------------------ | ------------------------- | :--: | :--: | :--: | :--: | :--: |
| Youth              | 2.4 – 4.7 in              |  1.2 |  2.4 |  3.6 |  4.7 |  5.5 |
| High School        | 3.0 – 5.6 in              |  2.0 |  3.0 |  4.5 |  5.6 |  6.6 |
| College            | 4.9 – 8.1 in              |  3.3 |  4.9 |  6.3 |  8.1 |  9.4 |
| Professional       | 5.8 – 9.0 in              |  3.4 |  5.8 |  7.8 |  9.0 | 11.0 |
| Broad (All Levels) | 3.3 – 7.1 in              |  1.9 |  3.3 |  4.9 |  7.1 |  9.1 |
