Supplemental oxygen should be available when training at elevation. Which option is correct?

• A. Do not use oxygen
• B. Have supplemental oxygen available when training at elevation
• C. Oxygen is unnecessary
• D. Only if symptomatic

Answer: (B)

Training at elevation exposes the body to less oxygen per breath, which can reduce oxygen delivery to tissues during exercise. Having supplemental oxygen available allows quick restoration of oxygen levels if someone becomes hypoxemic or starts showing altitude-related distress, helping to keep training safe and effective. That makes having oxygen on hand the best choice. Not using oxygen ignores the physiological challenge of high altitude, claiming oxygen is unnecessary is inaccurate, and waiting to use oxygen only after symptoms appear can delay treatment and increase risk.
