1. What is the Six Minute Walk Test?

The Six Minute Walk Test (6MWT) is a submaximal exercise test used to assess aerobic capacity and endurance. It measures the distance an individual can walk quickly on a flat, hard surface in six minutes.

2. How Does the Calculator Work?

The calculator uses the Six Minute Walk Test prediction equation:

Where:

• \( Height \) — Height in centimeters (cm)
• \( Age \) — Age in years
• \( Weight \) — Weight in kilograms (kg)
• \( Gender Factor \) — 309 for males, 0 for females

Explanation: This equation estimates the normal expected distance for healthy individuals based on anthropometric and demographic factors.

3. Importance of Six Minute Walk Test

Details: The 6MWT is widely used in clinical practice to assess functional capacity, monitor disease progression, and evaluate treatment effectiveness in various conditions including pulmonary, cardiac, and neuromuscular diseases.

4. Using the Calculator

Tips: Enter height in centimeters, age in years, weight in kilograms, and select gender. All values must be valid (height > 0, age between 1-120, weight > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is a normal Six Minute Walk Test distance?
A: Normal distances vary by age, gender, height, and weight. Generally, healthy adults walk 400-700 meters in six minutes.

Q2: How should the test be administered?
A: The test should be conducted on a flat, straight 30-meter course with standardized instructions and encouragement.

Q3: What factors can affect the test results?
A: Motivation, practice effect, learning, medications, supplemental oxygen, and comorbidities can all influence the distance walked.

Q4: When is the test contraindicated?
A: The test should not be performed in patients with unstable angina, recent myocardial infarction, or resting heart rate >120 bpm.

Q5: How is the result interpreted?
A: The actual distance walked is compared to predicted values. A distance less than 80% of predicted may indicate impaired functional capacity.
