Altitude | Definition |
---|---|
0–500 m | ‘Near sea level’ |
Above 500–2000 m | ‘Low altitude’: minor impairment of aerobic performance becomes detectable |
Above 2000–3000 m | ‘Moderate altitude’: mountain sickness starts to occur and acclimatisation is increasingly important for performance |
Above 3000–5500 m | ‘High altitude’: mountain sickness and acclimatisation become clinically relevant; performance is considerably impaired |
Above 5500 m | ‘Extreme altitude’: prolonged exposure leads to progressive clinical deterioration |
