Why do athletes train at high altitudes?

Extracts from this document...

Introduction

Why do athletes train at high altitudes? Athletes train at high altitudes to increase the energy available to the body. One way of doing this is to increase the amount of oxygen to the blood. At high altitudes (e.g. on the top of a mountain), the air is 'thin' and the oxygen content is much lower. ...read more.

Middle

What is 'thin' air? As the human body travels up in altitude, it is exposed to a state of hypoxia (low oxygen). The actual percentage of oxygen in the air doesn't change, but the barometric pressure decreases, and this in-turn decreases the amount of oxygen that can be extracted during respiration. This is what is meant by 'thin-air' at altitude. ...read more.

Conclusion

A decrease in maximum cardiac output, a decreased maximum heart rate 2. An increased number of red blood cells 3. Excretion of base via the kidneys to restore acid-base balance (this results in a lower tolerance for lactic acid) 4. A chemical change within the red blood cells that makes them more efficient at unloading oxygen to the tissues 5. An increase in the number of mitochondria and oxidative enzymes.
