Queens College Step Test Calculator

The Queens College step test estimates VO2 max from one recovery pulse: step up and down on a 16.25 inch (41.3 cm) bench for three minutes, men at 24 steps a minute and women at 22, then count your pulse for 15 seconds starting five seconds after you stop and multiply by four. Enter that number above. Men get 111.33 minus 0.42 times the recovery heart rate, women get 65.81 minus 0.1847 times it, both from McArdle 1972, and the calculator returns ml/kg/min with a band for your age and sex.

Queens College step test: recovery pulse to VO2 max

Estimated VO2 max in ml/kg/min. The two lines have different slopes because they came from two separate regressions, one on the men and one on the women in the original Queens College sample, and the women stepped at a slower cadence. Ten beats of recovery heart rate is worth 4.2 points for a man and 1.8 for a woman. That is a big lever, which is why the pulse count has to be done properly.

Why this is the workhorse test

It takes five minutes, needs no track and no weather, and the whole kit is a box, a metronome app and a way to count your pulse. The Cooper test is the reference, but it wants a track and 12 minutes at your limit. The Rockport walk test wants a measured mile. This one fits in a garage in January, and it repeats cleanly because there is nothing to pace.

What you need

A step or box 41 cm high. A standard 40 cm plyo box is close enough; a 50 cm box is a different test and reads low. A metronome app set to 96 beats per minute for men or 88 for women, one beat per foot movement: up, up, down, down. A clock. Your pulse, or a chest strap you can read at 5 to 20 seconds after you stop.

How to run it

Take the pulse at the wrist with two fingers, or at the side of the neck lightly, or read the chest strap. If you miss the 5-second start, do not guess; rest ten minutes and go again. Counting from 10 to 25 seconds instead of 5 to 20 loses several beats, which reads as two points of fitness that never happened.

What invalidates the result

The wrong box height. Cadence drift, which is why you use a metronome and not a feeling. Sitting down after you stop. A pulse count that started late or ran long. Caffeine within the hour, a hot room, a poor night, or stepping within two hours of a hard session, since every one of those lifts recovery heart rate for reasons the equation cannot see.

Reading the number honestly

McArdle and colleagues built the equations on college students at Queens College in New York in 1972. Young adults, in other words, and the further you sit from that group in age the more the estimate should be read as a band rather than a point. A shorter person does more relative work on a fixed 41 cm box than a taller one, which is a known bias in every step test with one bench height. The recovery pulse itself is one of the most day-to-day variable numbers in your body. So: a single result is a snapshot, the equation is a population average, and the trend across repeats under the same conditions is the part worth trusting.

For an idea of where the estimate should land, the max heart rate calculator gives you the ceiling the recovery pulse is falling from. The Harvard step test is the longer, harder cousin that scores recovery itself rather than converting it to oxygen. The VO2 max calculator has the Cooper version in short form.

Three minutes of stepping sounds gentle and takes most people past 150 bpm, so the same rule applies as for the others: a heart condition, chest pain on effort, or a doctor who told you to take it easy means you clear it first. Bad knees or shaky balance on a 41 cm box is its own reason to pick the walk test.

How Movement Rebels fits

The coach reads heart rate, HRV and resting heart rate from synced Garmin Connect and Apple Health data, sees your last 14 activities, and reads the morning readiness check-in, which is the same kind of signal this test is built around: how fast your body settles after work. It does not run the McArdle equation for you and it re-estimates nothing you did not sync. Put the VO2 number in "Notes for your coach" and it is in the brief. When you want to move it, the VO2 max intervals guide linked below is the session library.
