About the Queens College Step Test Calculator
The Queens College Step Test Calculator estimates VO2 max from recovery pulse after the standard 3-minute step test on a 41.3 cm bench. It applies a sex-specific equation to estimate aerobic capacity in mL/kg/min. The result depends on following the prescribed stepping cadence and recovery pulse timing.
- Sex used by formula
- Select Male or Female to choose the corresponding sex-specific equation and protocol cadence; this input has no units and defaults to Male.
- Recovery pulse (bpm)
- Enter the recovery heart rate in beats per minute, calculated by counting beats from 5 to 20 seconds after stepping ends and multiplying by 4; the default is 120 bpm.
Formula and method
Male: V = 111.33 − 0.42 × H. Female: V = 65.81 − 0.1847 × H.
- VEstimated VO2 max in milliliters of oxygen per kilogram of body mass per minute (mL/kg/min).
- HRecovery pulse in beats per minute (bpm), measured using the standard post-test timing.
Choose the equation for the selected sex, multiply recovery pulse by that equation's coefficient, and subtract the product from its intercept. Display the estimate to two decimal places. With the default Male selection and recovery pulse of 120 bpm, V = 111.33 − (0.42 × 120) = 60.93 mL/kg/min. The calculator also displays a reminder that the estimate requires the standard test protocol.

How to use the Queens College Step Test Calculator
- 1Select the sex used by the formula; the default is Male. Only attempt the test if stepping exercise is appropriate for your health and mobility.
- 2Use a stable 41.3 cm bench and step up-up-down-down for 3 minutes: 24 complete cycles per minute for males or 22 for females, corresponding to metronome settings of 96 or 88 beats per minute.
- 3After stopping, remain standing and count your pulse for 15 seconds, starting 5 seconds after the test ends and finishing at 20 seconds.
- 4Multiply the pulse count by 4 and enter the result in Recovery pulse (bpm), rather than entering the raw 15-second count.
- 5Read the estimated VO2 max and protocol note; with Male and 120 bpm entered, the estimate is 60.93 mL/kg/min.
Reading your result
Estimated VO2 max reports predicted maximal oxygen uptake relative to body mass, not a directly measured laboratory value. The default result of 60.93 mL/kg/min represents the prediction from the male equation at a recovery pulse of 120 bpm; higher estimates generally indicate greater aerobic capacity, but fitness classification requires appropriate reference standards. The Note row states: Requires the standard 3-minute, 41.3 cm bench protocol and recovery pulse timing. This is a condition for interpreting the estimate, not confirmation that the protocol was followed.
Limitations
These equations were developed in young college-age populations and may be less accurate for other ages, clinical populations, or people with very different fitness levels. Changing bench height, test duration, cadence, recovery posture, or pulse timing can make the estimate unreliable. Pulse-counting errors, medications that alter heart rate, illness, heat, caffeine, and fatigue can also affect results. The Male and Female options select the original binary equations and do not capture all individual physiological variation. This tool does not directly measure VO2 max, diagnose disease, or establish that exercise is safe; seek appropriate medical advice before testing if you have symptoms or health concerns, and stop for chest pain, dizziness, or unusual breathlessness.
Common questions
Do I enter the 15-second pulse count or beats per minute?+
Enter beats per minute. Count beats from 5 to 20 seconds after the test ends, then multiply that 15-second count by 4 before entering it.
Can I use a different bench height or stepping speed?+
Not while retaining the standard interpretation. The equations assume a 41.3 cm bench, 3 minutes of stepping, and 24 complete step cycles per minute for males or 22 for females.
Why does the Male default with 120 bpm produce 60.93 mL/kg/min?+
The male equation subtracts 0.42 times recovery pulse from 111.33: 111.33 − (0.42 × 120) = 60.93 mL/kg/min.
Can I use my smartwatch's recovery heart rate?+
Only if it accurately represents the prescribed recovery measurement window. A watch's generic recovery metric, end-of-exercise heart rate, or one-minute recovery value is not interchangeable with the pulse measured from 5 to 20 seconds after this test.
