Fitness Age Calculator

Formula

The formula to estimate fitness age is:

\[ \text{FA} = \text{AA} - \left( \frac{\text{V} - \text{AAV}}{0.3} \right) \]

Where:

\(\text{FA}\) is the estimated fitness age (years)
\(\text{AA}\) is the actual age (years)
\(\text{V}\) is the VO2 Max (ml/kg/min)
\(\text{AAV}\) is the average VO2 Max for the actual age (ml/kg/min)

What is Fitness Age?

Fitness age is an estimate of your body’s physical age based on your cardiovascular endurance. It is a concept that reflects how well your body functions physically, compared to how well it should work given your age. A lower fitness age compared to your chronological age generally indicates better cardiovascular health and is associated with a lower risk of lifestyle-related diseases.

Example Calculation 1

Let's assume the following values:

Actual Age (AA) = 35 years
VO2 Max (V) = 45 ml/kg/min
Average VO2 Max for Age (AAV) = 40 ml/kg/min

Using the formula:

\[ \text{FA} = 35 - \left( \frac{45 - 40}{0.3} \right) = 35 - \left( \frac{5}{0.3} \right) = 35 - 16.67 \approx 18.33 \text{ years} \]

The Estimated Fitness Age is approximately 18.33 years.

Example Calculation 2

Let's assume the following values:

Actual Age (AA) = 50 years
VO2 Max (V) = 35 ml/kg/min
Average VO2 Max for Age (AAV) = 30 ml/kg/min

Using the formula:

\[ \text{FA} = 50 - \left( \frac{35 - 30}{0.3} \right) = 50 - \left( \frac{5}{0.3} \right) = 50 - 16.67 \approx 33.33 \text{ years} \]

The Estimated Fitness Age is approximately 33.33 years.
