Human Performance Index

What this index measures

The GFF Index summarizes performance on standardized Global Fast Fit (GFF) benchmarks, including Standard, Pro, and Shuttle routines.

Reference population

• Rankings are computed using certified GFF video submissions only.
• No adjustments are applied for age, gender, location, or submission date.

Best performance rule

If a participant completes the same benchmark multiple times, only their best verified performance is used.

Index scale

Scores range from 1 to 100 and represent the percentage of participants in the reference set whose performance was worse than yours.

Example: A score of 72 indicates performance better than approximately 72% of verified GFF participants.

Important context

• This is not a comparison against the general population.
• It reflects performance within a self-selected, verified population capable of completing the GFF benchmark.

What this index measures

The Local Records Index summarizes real-world functional fitness based on verified exercise performances outside standardized benchmarks.

Exercise categories

All exercises are assigned to one of six functional categories:

• Balance / Agility / Flexibility
• Core
• Endurance
• Legs / Strength
• Speed
• Upper / Strength

Category scoring

For each category, a participant’s score reflects their best demonstrated performance within that category.

Overall fitness bias

The index rewards breadth across movement categories rather than specialization in a single exercise.

Index scale

LRI scores are reported on a 1–100 scale, where higher values indicate stronger overall functional capability within the verified reference population.

Composite index

The Global Human Performance Index combines standardized benchmark performance (GFFI) with real-world functional fitness (LRI).

Evidence-based calculation

• When both components are available, they contribute equally.
• When only one component is available, the index reflects the available evidence and is labeled accordingly.

Intended use

GHPI is designed for population-level comparison and analysis, not for medical assessment or personal training guidance.

Interpretation

Higher GHPI values indicate stronger overall human performance within the verified comparison population.
