6 Minute Walk Test Normative Values:
| From: | To: |
The 6 Minute Walk Test (6MWT) is a submaximal exercise test that assesses functional exercise capacity by measuring the distance a person can walk quickly on a flat, hard surface in 6 minutes. It is commonly used to evaluate cardiopulmonary and musculoskeletal function.
The calculator uses normative reference tables to determine percentile rankings:
Where:
Explanation: The calculator compares the measured distance against established normative values for the same age and sex group to determine percentile ranking.
Details: The 6MWT provides valuable information about functional capacity, treatment effectiveness, and disease progression in various conditions including heart failure, COPD, pulmonary hypertension, and musculoskeletal disorders.
Tips: Enter the total distance walked in meters, age in years, and select biological sex. Ensure the test was conducted according to standard protocols on a measured course.
Q1: What is a normal 6MWT distance?
A: Normal distances vary by age and sex, but generally range from 400-700 meters for healthy adults, with younger individuals and males typically achieving longer distances.
Q2: How should the test be administered?
A: The test should be conducted on a measured, flat course (usually 30 meters) with standardized instructions and encouragement.
Q3: What factors affect 6MWT performance?
A: Age, sex, height, weight, comorbidities, motivation, and practice effects can all influence test results.
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 significant is the learning effect?
A: A practice test is recommended as performance typically improves by 10-30 meters on the second test due to familiarization.
