Rockport Equation:
| From: | To: |
The Rockport 1 Mile Test is a submaximal fitness test that estimates VO2max (maximum oxygen consumption) from a 1-mile walk. It provides a simple way to assess cardiovascular fitness without requiring maximal exertion.
The calculator uses the Rockport equation:
Where:
Explanation: The equation estimates VO2max based on body weight, age, walking time, and heart rate measured immediately after completing the 1-mile walk.
Details: VO2max is a key indicator of cardiovascular fitness and aerobic endurance. It helps assess overall health status, track fitness progress, and identify potential cardiovascular risks.
Tips: Enter your weight in pounds, age in years, time to complete 1 mile in minutes, and heart rate measured immediately after the walk. All values must be valid positive numbers.
Q1: How accurate is the Rockport test compared to lab testing?
A: While not as precise as laboratory VO2max testing, the Rockport test provides a reasonably accurate estimate for most healthy adults, with correlation coefficients around 0.88-0.93.
Q2: What are normal VO2max values?
A: Normal values vary by age, gender, and fitness level. Generally, values above 40 ml/kg/min for men and 35 ml/kg/min for women are considered good for most age groups.
Q3: When should I measure my heart rate?
A: Measure your heart rate immediately upon completing the 1-mile walk, ideally within 15 seconds of finishing.
Q4: Are there limitations to this test?
A: The test may be less accurate for very fit individuals, older adults, or those with certain medical conditions. It assumes a consistent walking pace throughout the test.
Q5: How often should I perform this test?
A: Every 4-6 weeks is recommended to track fitness progress. Allow adequate recovery between tests and perform under similar conditions each time.
