Official protocol by Léger & Lambert (1982) · Aerobic Capacity
20 Meter Shuttle Run Test (Beep Test)
Estimate the maximal oxygen uptake (VO2max) and cardiorespiratory endurance
Primary measureShuttle / Level completed
CategoryAerobic Capacity
FormatPROGRESSIVE
Pacing audio0.01s Calibrated
Standardized testing protocol
Participants repeatedly run a 20-meter distance, turning around at the beep, at increasing speeds. The protocol starts at 8.0 or 8.5 km/h and increases by 0.5 km/h every minute. The test ends when the subject can no longer keep pace for 2 consecutive runs.
Required field equipment
Marked distance of 20 meters on a flat surface, Time4Test audio pacing engine
Calculation formula & scoring
Time4Test automates this equation directly during the session:
VO2max is predicted from assessment performance using standardized regression equations based on level/shuttle completed.
