Bruce Protocol METs Calculator

Estimate VO₂ max from treadmill test time.

VO₂ max (ml/kg/min) 42.42

METs 12.12

Formula: Bruce regression on test duration

Step-by-step with your numbers:

1. Values used:

2. Test time = 12

4. VO₂ max = 42.42ml/kg/min

5. METs = 12.12

Did we solve your problem today?

The Bruce treadmill protocol estimates aerobic fitness from how long you last.

The math behind it

Gender-specific regressions convert test duration to VO₂ max; 1 MET = 3.5 ml/kg/min.

Male lasting 12 minutes → about 47 ml/kg/min.

What is the Bruce protocol?

A treadmill test that raises speed and incline every 3 minutes.
