- VO2max = 31.025 + 3.238X - 3.248A + 0.1536AX
- Variables
- X
- Speed of the last completed stage, km/h. X = 8 + 0.5 × level.
- A
- Age in years for ages 8–17. Held at 18 for adults.
- VO2max
- Estimated maximal oxygen uptake, ml/kg/min.

- Notes
- 20 m shuttle, 1-minute stages starting at 8.5 km/h, plus 0.5 km/h each minute. The 1982 Léger–Lambert paper used 2-minute stages and a different regression; this card is the 1988 protocol.
