Rockport Equation:
| From: | To: |
The Rockport Fitness Walking Test is a submaximal exercise test that estimates VO2max (maximal oxygen consumption) from a 1-mile walk. It provides a convenient way to assess cardiovascular fitness without requiring maximal exertion.
The calculator uses the Rockport equation:
Where:
Explanation: The equation estimates maximal oxygen consumption based on body weight, age, walking time, and heart rate response to exercise.
Details: VO2max is the gold standard measure of cardiovascular fitness. It indicates the maximum amount of oxygen your body can utilize during intense exercise and is a strong predictor of overall health and longevity.
Tips: Enter your weight in pounds, age in years, time to complete 1-mile walk in minutes, and heart rate at the end of the walk. All values must be valid positive numbers.
Q1: How accurate is the Rockport test?
A: The Rockport test provides a reasonably accurate estimate of VO2max for most healthy adults, with correlation coefficients around 0.88 compared to laboratory measurements.
Q2: What are normal VO2max values?
A: VO2max 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: Who should not take this test?
A: Individuals with cardiovascular disease, respiratory conditions, orthopedic limitations, or other health concerns should consult a physician before attempting the test.
Q4: How should I prepare for the test?
A: Wear comfortable walking shoes, avoid heavy meals 2-3 hours before testing, and ensure proper hydration. Warm up for 5-10 minutes before starting the timed walk.
Q5: Can I use this test to track fitness progress?
A: Yes, the Rockport test is excellent for tracking cardiovascular fitness improvements over time when performed under consistent conditions.
