Six Minute Walk Test Equation:
| From: | To: |
The Six Minute Walk Test (6MWT) is a submaximal exercise test that assesses functional capacity by measuring the distance a person can walk quickly on a flat, hard surface in six minutes. It is widely used in clinical practice to evaluate exercise tolerance in various patient populations.
The calculator uses the Six Minute Walk Test prediction equation:
Where:
Explanation: This equation provides the predicted distance for a healthy individual based on their height, age, and weight, which can be compared to the actual distance walked during the test.
Details: The 6MWT is a simple, inexpensive, and well-tolerated test that provides valuable information about functional exercise capacity. It is commonly used in cardiopulmonary rehabilitation, preoperative assessment, and monitoring disease progression.
Tips: Enter height in centimeters, age in years, and weight in kilograms. All values must be valid positive numbers. The result shows the predicted distance in meters that a healthy individual of similar characteristics would walk in six minutes.
Q1: What is a normal six minute walk distance?
A: Normal values vary by age, gender, height, and weight. Generally, healthy adults walk 400-700 meters. The predicted value from this calculator provides an individualized reference.
Q2: Who should not perform the 6MWT?
A: Individuals with unstable angina, recent myocardial infarction, uncontrolled hypertension, or other conditions that may be exacerbated by exercise should avoid the test.
Q3: How is the actual test conducted?
A: The test is performed on a measured course (usually 30 meters), with standardized instructions and encouragement. Vital signs are monitored before and after.
Q4: What factors affect six minute walk distance?
A: Age, height, weight, gender, motivation, comorbidities, musculoskeletal limitations, and practice effects can all influence the distance walked.
Q5: How is the result interpreted?
A: The actual distance walked is compared to predicted values. Significant deviation (usually <80% of predicted) may indicate impaired functional capacity.
