 Tibetans Adapted to High-Altitude LivingA new study claims that Tibetans adapted to living at high altitudes in less than 3,000 years, the fastest genetic change ever observed in humans. According to the study, the Tibetans and the Han Chinese split into two separate populations about 2,750 years ago. By comparing the genomes of members of both ethnic groups, researchers were able to identify more than 30 genes with DNA mutations that have become more prevalent in Tibetans than Han Chinese. Nearly half of these mutations are related to how the body uses oxygen, which is present in much lower levels at high altitudes. More...

Many people do not realize that New Mexico has some areas where the elevation is more than 13000 feet above sea level (Wheeler Peak, near Red River). People who arrive in Santa Fe (over 7 thousand feet above sea level) from someplace that is sea level often have medical problems and some so severely that they need to leave.
Many long distance runners and mountain bikers like to train in our mountain areas. Then, when they compete at some place with a lower altitude, they have a real advantage. I have noticed that when I visit my family in Texas, my sisters and I will go for a brisk two mile walk and they are winded when we finish. The altitude there is about 200 feet above sea level. It seems like nothing to me.

I used to train in the Sequoia National Forest in California during the summer so that during the Cross Country season my body would not tire as easily (your muscles usually become fatigued from lack of oxygen).
