Endurance performance at high altitude over 3000 m is severely affected due to

Endurance performance refers to an athlete's ability to sustain high-intensity exercise for an extended period of time.

Key Points

• At high altitudes above 3000 meters, the air pressure decreases, leading to a decrease in the partial pressure of oxygen in the air.
• This can make it more difficult for the body to deliver oxygen to the working muscles during exercise, which can lead to fatigue and decreased endurance performance.
• Athletes who train at high altitudes may experience adaptations such as increased red blood cell production, which can help to improve oxygen delivery and mitigate the effects of altitude on endurance performance.
