Official protocol by Cazorla (1990) · Lactate Threshold
University of Bordeaux Test (TUB2)
Determine Maximal Aerobic Speed and Anaerobic Threshold via blood lactate measurement
Primary measureVMA (km/h) + Lactate (mmol/L)
CategoryLactate Threshold
FormatPROGRESSIVE
Pacing audio0.01s Calibrated
Standardized testing protocol
Progressively increasing speed in 3-minute stages followed by 1-minute recovery for blood sampling. Speed increases by 0.5 km/h each stage.
Required field equipment
Running track (200m), Time4Test pacing audio, stopwatch, heart rate monitor, lactate sampling tools
Calculation formula & scoring
Time4Test automates this equation directly during the session:
VMA (km/h) of last completed stage and blood lactate concentration (mmol/L).
