6 Minute Walk Test VO2 Max Calculator

Formula

The formula to calculate the VO2 Max based on the 6-minute walk test is:

\[ VO2_{max} = \begin{cases} (7.57 \times H) - (5.02 \times A) - (1.76 \times W) - 309 & \text{if male} \\ (2.11 \times H) - (2.29 \times W) - (5.78 \times A) + 667 & \text{if female} \end{cases} \]

Where:

\( VO2_{max} \) is the estimated VO2 Max (ml/kg/min).
\( H \) is the height in cm.
\( A \) is the age in years.
\( W \) is the weight in kg.

Example

Let's say the distance walked (\( D \)) is 600 meters, the age (\( A \)) is 45 years, the weight (\( W \)) is 70 kg, and the height (\( H \)) is 170 cm. For a male, using the formula:

\[ VO2_{max} = (7.57 \times 170) - (5.02 \times 45) - (1.76 \times 70) - 309 \]

We get:

\[ VO2_{max} = 1286.9 - 225.9 - 123.2 - 309 = 628.8 \, \text{ml/kg/min} \]

So, the estimated VO2 Max for this individual is 628.8 ml/kg/min.

What is the 6 Minute Walk Test?

The 6-minute walk test (6MWT) is a submaximal exercise test that measures the distance an individual can walk in six minutes. It is used to assess the functional status of patients with various cardiopulmonary conditions.
