Queens College Step Test Calculator
Calculate your VO2 Max using the scientifically validated Queens College Step Test with post-exercise heart rate measurement
Queens College Step Test
The Queens College Step Test (QCST) is a scientifically validated submaximal exercise test for predicting VO2 max. Research by Chatterjee et al. (2004) demonstrates strong correlation (r=0.95) between step test performance and actual VO2 max measurements, making it an excellent field test for cardiovascular fitness assessment.
Scientific Formula
The Queens College Step Test uses gender-specific regression equations for accurate VO2 max predictions: Males: VO2 max = 111.33 – (0.42 × HR) and Females: VO2 max = 65.81 – (0.1847 × HR) where HR is the heart rate 15 seconds after completing the 3-minute step test.
Test Protocol
Step up and down on a 16.25-inch (41.3 cm) bench for 3 minutes at a rate of 22 steps per minute for females and 24 steps per minute for males. Measure heart rate 15 seconds after completion. The test is safe, standardized, and suitable for most populations.
Accuracy & Validity
Studies show 90-95% correlation with laboratory VO2 max testing. Validation research demonstrates the QCST as highly reliable and valid for fitness assessment across diverse populations.
Queens College Step Test Formula Details
Male Formula
VO2 max = 111.33 - (0.42 × HR)
Variables:
- HR = Heart rate 15 seconds after test completion (BPM)
- Stepping rate: 24 steps per minute
- Test duration: 3 minutes
- Bench height: 16.25 inches (41.3 cm)
Female Formula
VO2 max = 65.81 - (0.1847 × HR)
Variables:
- HR = Heart rate 15 seconds after test completion (BPM)
- Stepping rate: 22 steps per minute
- Test duration: 3 minutes
- Bench height: 16.25 inches (41.3 cm)
Calculation Example
Subject: 25-year-old male, 140 BPM heart rate after test
Calculation:
VO2 max = 111.33 – (0.42 × 140)
VO2 max = 111.33 – 58.8
Result: VO2 max = 52.5 ml/kg/min

Test Administration Protocol
Pre-Test Preparation
- Equipment: 16.25-inch (41.3 cm) bench or step platform
- Metronome: Set to appropriate cadence (22/24 steps per minute)
- Heart rate monitor: Or manual pulse counting capability
- Stopwatch: For precise timing of test and recovery
- Medical clearance: Ensure participant is healthy for moderate exercise
Warm-up Protocol
- 5 minutes: Light walking or marching in place
- Practice stepping: 30 seconds at test pace to familiarize
- Dynamic stretching: Leg swings, calf raises, ankle circles
- Rest period: 2-3 minutes before test start
- Final check: Ensure metronome is audible and equipment ready
Test Execution
- Duration: Exactly 3 minutes of continuous stepping
- Stepping pattern: Up-up-down-down (both feet up, both feet down)
- Cadence: Males 24 steps/min, Females 22 steps/min
- Posture: Maintain upright posture, full extension on step up
- Safety: Stop immediately if participant feels faint or dizzy
Post-Test Recovery
- Immediate sitting: Participant sits down immediately after test
- Heart rate measurement: Count pulse for 15 seconds starting 5 seconds after test
- Cool-down: 5-10 minutes light walking
- Hydration: Provide water as needed
- Recovery monitoring: Ensure heart rate returns to normal

Test Optimization Tips
Proper Stepping Technique
Maintain consistent rhythm with metronome. Step fully onto platform with complete leg extension, then step down with control.
Heart Rate Accuracy
Use radial or carotid pulse for 15-second count. Start counting exactly 5 seconds after test completion for standardized results.
Safety Considerations
Ensure stable platform, non-slip surface, and immediate access to seating. Monitor for signs of overexertion throughout test.
Related Assessments
Combine with strength assessments for comprehensive fitness evaluation.
