How is the Astrand bike test performed?

Cycle at a constant workload for 6 minutes achieving a steady-state heart rate between 125-170 bpm. Record the HR and power output, then apply the Astrand formula.

What workload should be used?

Set an initial workload of 50-100W for women or 100-150W for men. Adjust so that steady-state HR falls between 125 and 170 bpm during minutes 5-6.

How accurate is this method?

The Astrand protocol has a standard error of about 10-15% compared to maximal testing, which is typical for submaximal estimation methods.
