Altitude Adaptation Calculator

How to calculate altitude adaptation?

Altitude-driven erythropoiesis is the physiological process where exposure to lower oxygen levels at high altitudes triggers the kidneys to produce more erythropoietin (EPO), which in turn stimulates red blood cell production.

The formula used to estimate this adaptation is: Est. Hct = Baseline + (Days × 0.15)

Using the calculator: An altitude camp example

Imagine an athlete with a baseline hematocrit level of 40% who attends a 21-day training camp at high altitude.

Step-by-step calculation:

• Baseline measurement: 40%
• Adaptation gain: 21 days × 0.15 = 3.15%
• Final estimated result: 43.15%

Frequently Asked Questions

What is a normal hematocrit range?
Typically 38-50% for men and 34-44% for women.

Do these coefficients apply to everyone?
No, individual adaptation rates vary based on genetics, hydration, and nutrition.

Does altitude height matter?
Yes, these average coefficients typically apply to moderate-high altitudes between 2,000m and 3,000m.
