About cadlo.fit
A reference site on field fitness tests, written by the people who coded the beeps.
Who is responsible for this site
cadlo.fit is published by InsightIQ, a French development studio that designs and publishes the Cadlo app for iPhone and Android. Editorial responsibility lies with the publisher, not with an individual writer: we are developers, not physiologists or coaches, and the site claims no personal sports expertise. What it brings is the exact protocol data, the same data that drives the beeps in the app, and cited sources for everything else. Pages are drafted with assistance by the team that implemented each protocol in the app, then checked automatically before publication: every figure is compared with the data that drives the beeps in the app, every cited source must respond and contain the figures quoted, and an independent review blocks any page that contradicts that data or states a standard without a document. Every page carries the date of its last real change.
Where the numbers come from
Level tables, speeds, distances and durations come from a single data file, the same one that drives the beeps in the app. When a Cadlo user compares the app with an official recording and reports a gap, the fix is made in that file and propagates to every page on the site. VO₂max estimates use the equation published with each test where one exists: Léger and colleagues (1988) for the 20 m shuttle run, Bangsbo for the Yo-Yo tests, Buchheit for the 30-15 IFT, Cooper for the 12-minute run; for the other tests that return a MAS, the Daniels and Gilbert model. Entry-test standards cite the regulation or official document they come from, with the date checked.
What the site does not do
It gives no medical advice. A maximal test is a hard effort: if in doubt about your health, ask a doctor before taking it. Level benchmarks are orders of magnitude to place a result, not norms. Entry-test standards change with each regulation: the version that counts is the one from the body running the test.
Our sourcing rules
A protocol figure comes from the published protocol and from the app’s data file. An entry-test standard is only published with the official text that sets it, and the date we checked it. A norm or population benchmark cites the study it comes from; when none exists, it is presented as a working order of magnitude, never as a threshold. A page that fails these rules is not published.
Report an error
A speed that does not match your audio track, an outdated standard, a typo: write to contact@insightiq.dev with the page address. Data corrections are handled first, and every correction made to a live page is logged, with its date, on the Corrections page.
Where to check that we exist
The app is on the App Store and Google Play under its publisher’s name, and its test catalogue is the one on this site. App Store · Google Play · insightiq.dev
