# Relative Hand Position - Up

> Distance along the up axis (+) 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_up`
* **Aggregation:** mean
* **Precision:** 1
* **Measurement:** Vertical distance from mid-shoulders to average wrist position
* **Direction:** Above (+) or below (-)

* **Typical Range:** 1.9 – 5.6 in
* **Optimal Direction:** Middle — moderate values are optimal

## Description

Relative hand position up measures the vertical position of the hands relative to the shoulders at foot contact, indicating hand height and swing setup.

## 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              | 1.7 – 3.7 in              |  0.6 |  1.7 |  2.6 |  3.7 |  4.6 |
| High School        | 1.7 – 4.1 in              |  0.2 |  1.7 |  2.8 |  4.1 |  5.9 |
| College            | 2.4 – 5.8 in              |  0.3 |  2.4 |  4.5 |  5.8 |  7.4 |
| Professional       | 4.0 – 8.2 in              |  0.8 |  4.0 |  6.2 |  8.2 |  9.5 |
| Broad (All Levels) | 1.9 – 5.6 in              |  0.4 |  1.9 |  3.5 |  5.6 |  7.8 |
