It is the spring of 2016, and you are a runner from Houston, Texas ( near sea level) who has come to Mexico city, Mexico (altitude: 7349 above sea level) to train for the olympics.

Initially, how will the high altitude affect your performance?

Solution

Answer:

The high altitude affect your performance so that changes in normal PaO, which has to be always 80mm of Hg to 100mm of Hg pressure. In the above case, a healthy person performing exercise at moderate altitude ( runner from Houston, Texas ( near sea level) who has come to Mexico city) and produced arterial blood gas pressure approximately 82mm of Hg. At higher altitudes, oxygen levels reduced leading to hypoxia and hypocapnia result \"reduction in PaO2\". At moderate altitude level, if that health person is not increased exercise intensity then there will be no much change in alveolar and arterial oxygen gas pressure. Normally exercise capability reduces as the altitude increases due to low oxygen availability to muscle cells.

The oxygen levels are generally lower at higher altitudes i.e. runner performing exercise in Houston, Texas ( near sea level) who has come to Mexico city. This increases the rate of respiration to get enough oxygen to meet the metabolic demands. This decreases the blood CO2 levels and causes respiratory alkalosis under high performance. At higher altitudes, oxygen levels reduced leading to hypoxia and hypocapnia result \"reduction in PaO2\".

B. The atmospheric pressure of oxygen decreases at high altitudes. People living at higher altitudes are adapted to lower P_O2 levels. One of the key change observed in this adaptation is increased 2, 3-BPG (2, 3- bisphosphoglycerate), which shift P₅₀ to higher values.
