🏃♂️ 1.5 Mile VO₂ Max Test Calculator
Calculate your cardiovascular fitness using the scientifically validated 1.5-mile run test with gender-specific regression equations
1.5 Mile Run VO₂ Max Test
The 1.5-mile run test is a scientifically validated field test for predicting VO₂ max using gender-specific regression equations. Research by McNaughton et al. (1998) demonstrates strong correlation (r=0.87) between 1.5-mile run performance and actual VO₂ max measurements, making it one of the most accurate field tests available.
Scientific Formulas
Gender-specific regression equations provide accurate VO₂ max predictions.
Male: VO₂max = 108.844 – (0.1636 × Weight_kg) – (1.438 × Time_min) – (0.1928 × Age)
Female: VO₂max = 100.434 – (0.1636 × Weight_kg) – (1.438 × Time_min) – (0.1928 × Age)
Validated research confirms these equations’ accuracy.
Test Protocol
Complete 1.5 miles (2.4 km) as quickly as possible on a flat, measured course. Proper warm-up and pacing strategy are essential for accurate results. The test requires maximal effort and should only be performed by individuals cleared for vigorous exercise.
Accuracy & Validity
Studies show 85-90% correlation with laboratory VO₂ max testing. Comparative research demonstrates the 1.5-mile run as the most accurate field test, superior to Cooper 12-minute run and shuttle tests.
Regression Equation Details
Male Formula
VO₂max = 108.844 - (0.1636 × BW_kg) - (1.438 × T_min) - (0.1928 × Age)
Variables:
- BW_kg = Body weight in kilograms
- T_min = Run time in minutes (decimal)
- Age = Age in years
Female Formula
VO₂max = 100.434 - (0.1636 × BW_kg) - (1.438 × T_min) - (0.1928 × Age)
Key Differences:
- Lower baseline constant (100.434 vs 108.844)
- Same weight, time, and age coefficients
- Accounts for physiological differences
Calculation Example
Subject: 30-year-old male, 75 kg, 12:30 run time
Calculation:
VO₂max = 108.844 – (0.1636 × 75) – (1.438 × 12.5) – (0.1928 × 30)
VO₂max = 108.844 – 12.27 – 17.975 – 5.784
Result: VO₂max = 72.8 ml/kg/min

Test Administration Protocol
Pre-Test Preparation
- Medical Clearance: Ensure participant is cleared for vigorous exercise
- Course Setup: Flat, measured 1.5-mile (2.4 km) track or route
- Weather: Avoid extreme temperatures (ideal: 50-70°F, low humidity)
- Timing: Avoid testing within 3 hours of eating
- Equipment: Accurate stopwatch, measured course, comfortable running shoes
Warm-up Protocol
- 5-10 minutes: Light jogging or brisk walking
- Dynamic stretching: Leg swings, high knees, butt kicks
- Pace familiarization: 2-3 short accelerations
- Rest period: 2-3 minutes before test start
- Hydration: Small sips of water as needed
Test Execution
- Pacing strategy: Aim for negative split (faster second half)
- Effort level: 85-95% maximum perceived exertion
- Monitoring: Record split times at 0.5-mile intervals
- Safety: Have medical personnel available for high-risk participants
- Motivation: Provide encouragement and time updates
Post-Test Recovery
- Cool-down: 5-10 minutes walking
- Stretching: Static stretches for major muscle groups
- Hydration: Replace fluids lost during test
- Monitoring: Check for signs of overexertion
- Documentation: Record exact time, environmental conditions
Field Test Comparison
| Test Type | Duration | Correlation with VO₂ Max | Advantages | Limitations |
|---|---|---|---|---|
| 1.5 Mile Run | 6-25 minutes | r = 0.87 | High accuracy, standardized | Requires maximal effort |
| Cooper 12-min Run | 12 minutes | r = 0.87 | Fixed time duration | Pacing challenges |
| 20m Shuttle Run | 5-15 minutes | r = 0.82 | Progressive intensity | Lower correlation |
| Submaximal Cycle | 6-12 minutes | r = 0.85 | Safer for at-risk populations | Requires equipment |
