Athletes arrive three weeks prior to an event that takes place at a high altitude. In the first few days, the athletes usually notice that they have less stamina and tire more easily than at sea level. Their heartbeat is also faster. As they continue training at high altitude, they notice that they can run for longer periods of time and experience less fatigue. Their heartbeat returns to a normal level as well. After the athletes return to life at sea level, they lose their ability to perform at a high altitude. The changes were due to acclimatization and not adaptation at a high altitude.

1. Explain the physiological symptoms experienced by the athletes in the first week of training due to high altitude.

2. Explain the acclimatization that takes place in the respiratory system as the athletes continue training at high altitude.

3. Compare and contrast the acclimatization and adaptation of respiration at a high altitude.
