1. What is the 6 Minute Walk Test MET Calculator?

The 6 Minute Walk Test MET Calculator estimates metabolic equivalent of task (MET) from the distance walked during a 6-minute walk test. This provides an objective measure of functional exercise capacity and cardiovascular fitness.

2. How Does the Calculator Work?

The calculator uses the 6MWT MET equation:

\[ MET = \frac{Distance\ (m)}{6\ min} \div 3.5 \]

Where:

\( Distance \) — Distance walked in meters during 6 minutes
\( 6\ min \) — Test duration in minutes
\( 3.5 \) — Conversion factor to METs (1 MET = 3.5 mL/kg/min)

Explanation: The equation converts walking speed to oxygen consumption and then to metabolic equivalents, providing a standardized measure of exercise intensity.

3. Importance of MET Calculation

Details: MET calculation from 6MWT helps assess functional capacity, monitor disease progression, evaluate treatment effectiveness, and guide exercise prescription in various patient populations.

4. Using the Calculator

Tips: Enter the total distance walked during the 6-minute walk test in meters. Ensure accurate measurement in a standardized testing environment with proper supervision.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal 6MWT distance?
A: Normal values vary by age, gender, and height, but generally range from 400-700 meters for healthy adults. Reference equations are available for specific populations.

Q2: How accurate is MET estimation from 6MWT?
A: It provides a reasonable estimate for clinical purposes, though individual variations in walking economy can affect accuracy compared to direct oxygen consumption measurement.

Q3: Who should undergo 6-minute walk testing?
A: Patients with cardiopulmonary diseases, elderly individuals, pre-operative assessment, and anyone requiring functional capacity evaluation.

Q4: What factors affect 6MWT performance?
A: Age, gender, height, weight, comorbidities, motivation, practice effect, and testing environment can all influence results.

Q5: How should the test be administered?
A: In a straight, flat corridor (30m minimum), with standardized instructions and encouragement. Vital signs should be monitored before and after.
