Performance Index

A composite 1–99 score combining six athletic qualities (speed, acceleration, agility, jump, power, strength) into one number.

Last updated May 20, 2026

A Performance Index is a composite athletic score — Performance House uses a 1–99 scale — built by scoring each athlete across six categories (speed, acceleration, agility, jump, power, relative strength) against a reference distribution, then aggregating the categories into a single value.

The model is built on peer-reviewed sprint research (Furusawa 1927; Samozino & Morin 2015–2016) and calibrated against published NFL Combine population data (Clark et al. 2017). Each sub-score is computed as a percentile against gender- and sport-specific reference distributions; weights are customizable per organization.

The composite reduces six trend lines to one — useful for cross-position comparison, longitudinal tracking, and stakeholder reporting. The accompanying per-category radar is where the actual coaching information lives.

Where it's used

Athlete-management platforms and sport-science batteries that need a single "all-round athleticism" number on top of raw test results.
