Altitude training is usually carried out at approximately what elevation where the partial pressure of oxygen is lower?

• A. 1500m
• B. 1000m
• C. 2500m+
• D. 4000m+

Answer: (C)

Altitude training relies on creating a hypoxic environment, where the partial pressure of oxygen is lower due to reduced barometric pressure as elevation increases. This low PO2 stimulates adaptations such as increased red blood cell production and enhanced oxygen transport and utilization. The typical training altitude is about 2,500 meters or higher, which provides a meaningful hypoxic challenge without becoming impractical for most athletes. At around 1,000–1,500 meters the reduction in PO2 is less pronounced, offering a weaker stimulus, while very high elevations (around 4,000 meters and above) impose greater stress and are not as commonly used for standard programs. Thus, the usual altitude training elevation is roughly 2,500 meters and above.
