What is the Astrand nomogram?

The Astrand nomogram is a graphical tool that estimates VO2 max from submaximal exercise heart rate and workload. The calculator applies the same mathematical relationships digitally.

What age correction factor is used?

Astrand provided age correction factors: at age 25 the factor is 1.0, decreasing to 0.75 at age 65. This corrects for the decline in maximal HR with age.

Is the nomogram still used clinically?

While more sophisticated protocols exist, the Astrand nomogram remains widely used in occupational health and general fitness assessment due to its simplicity and validated accuracy.
