History of the Bleep Test

Luc Léger’s original research

The multi-stage fitness test (MSFT) is commonly described as the Léger test because of the published work associated with Léger and colleagues. A 1984 paper by Léger and Lambert (with co-authors) describes a 20m shuttle run test with approximately one-minute stages for children and adolescents in Québec. This work is often cited as part of the foundation for the standardised 20m shuttle run format.

What mattered about this research approach was the combination of simplicity and repeatability: a measured distance, an audio-controlled pace, and a stage structure that lets large groups be tested with consistent timing.

Over time, the same underlying test acquired multiple names depending on the setting. “Multi-stage fitness test”, “20m shuttle run”, “beep test” and “bleep test” are often used interchangeably, while “PACER” is commonly used in US school environments for similar progressive shuttle testing.

Development through the 80s

The bleep test format was further developed and published in the late 1980s. In 1988, Léger, Mercier, Gadoury and Lambert published “The multistage 20 metre shuttle run test for aerobic fitness” in the Journal of Sports Sciences. This paper is widely referenced in discussions of how the test can be used to assess aerobic fitness and to support VO2 max estimation in field settings.

A practical feature of the Léger protocol is that the pace increases across levels (commonly in 0.5 km/h steps), and the number of shuttles per level is chosen so each level lasts about a minute. This made the test easy to record and communicate: results are written as level.shuttle (for example, 10.2).

Standardised audio tracks and score sheets also helped the test spread. Once organisations could play a recording and apply the same rules (reach the line by the beep, stop after repeated misses), they could compare results across intakes, seasons, and training blocks with minimal equipment.

Adoption by sports / military

Once the shuttle-run format was established, adoption followed because it solved a real problem: many organisations needed a scalable aerobic fitness test that could be run in limited space with minimal equipment.

As a result, the bleep test became common in:

• Schools: a practical class-based endurance assessment (including PACER-style versions).
• Sports: used either as a baseline aerobic test or as part of a broader testing battery.
• Military and emergency services: used as a repeatable selection or readiness test in some jurisdictions (often alongside strength/endurance and job-task elements).

In many applied settings, the test is valued less as a perfect model of match or job demands and more as a consistent benchmark: it is easy to repeat and it tracks fitness changes over time.

Variations over time

Over time, several variations emerged for practical and sport-specific reasons:

• 15m MSFT: a shorter shuttle distance used when space is limited (common in some UK recruitment formats).
• PACER: a school-focused shuttle test used in US PE contexts; usually scored as laps rather than level.shuttle.
• Yo-Yo tests: intermittent shuttle tests that include short recovery periods to better reflect stop-start sports (often used in football and rugby).

These variations are one reason bleep test tables and “what’s a good score?” questions can become confusing. A score only makes sense when the test version is known (20m vs 15m, MSFT vs PACER, and which audio track).

Related reference: the bleep test levels chart explains the structure of the standard 20m table, and the Yo-Yo test page covers one of the most common sport-specific alternatives.

Summary

• “Bleep test” is the MSFT shuttle run
• Léger’s 1980s research underpins the 20m format
• Adopted widely because it scales
• Many variants exist (15m, PACER, Yo-Yo)
