1. What is Fitness Age?

Fitness Age is a concept that compares your VO2max (a measure of cardiovascular fitness) to others of your chronological age. It estimates how "young" or "old" your body is based on your aerobic fitness level.

2. How Does the Calculator Work?

The calculator uses the fitness age formula:

Where:

• \( \text{Chronological Age} \) — Your actual age in years
• \( \text{VO2max} \) — Your maximum oxygen consumption (mL/kg/min)
• \( \text{VO2max average} \) — Average VO2max for your age group

Explanation: For every 1 mL/kg/min your VO2max is above average, your fitness age decreases by 0.2 years. Conversely, if your VO2max is below average, your fitness age increases.

3. Importance of Fitness Age

Details: Fitness age has been shown to be a better predictor of longevity than chronological age. A younger fitness age indicates better cardiovascular health and lower risk of chronic diseases.

4. Using the Calculator

Tips: Enter your chronological age in years, your measured VO2max, and the average VO2max for your age group. VO2max can be measured through exercise testing.

5. Frequently Asked Questions (FAQ)

Q1: How can I measure my VO2max?
A: The most accurate method is through a maximal exercise test in a lab. Fitness trackers and smartwatches also provide estimates based on heart rate data during exercise.

Q2: What are typical VO2max averages by age?
A: Average VO2max declines with age. For example: 30s (35-40), 40s (30-35), 50s (25-30), 60s (20-25) mL/kg/min (varies by gender).

Q3: Can I improve my fitness age?
A: Yes! Regular aerobic exercise can increase your VO2max, thereby decreasing your fitness age.

Q4: How accurate is this calculation?
A: It provides a general estimate. For precise assessment, consult with an exercise physiologist.

Q5: Why was 0.2 used in the formula?
A: This coefficient reflects the observed relationship between VO2max and mortality risk in population studies.
