Methodology

Useful results, not isolated numbers

ATHLOMETRY uses established field equations and shows the formula behind each calculation. When a result is an estimate —such as VO₂ max, HRmax or jump power— we state that clearly.

Formula shownWe explain how each result is calculated.

Context before labelsWe prioritise useful values and context over universal classifications that do not exist.

Simple privacyCalculations run in your browser and currently require no account.

ATHLOMETRY

A platform that will keep growing

The public version covers endurance, running, strength, power, cycling and change of direction. We will add new tools when they provide real value.
