Dear MEL Topic Readers,
The biological secrets that make Sherpas superhuman mountaineers
Who are Sherpas? They are people of Tibetan stock living in the Nepalese Himalayas. They often serve as porters on mountain-climbing expeditions. When mountain climbers try to conquer a high peak in Himalayas, they usually hire Sharpers to help them guide the way and carry necessary equipment and supplies.
It has been known that they possess extraordinary physical strength in such high altitudes but had never been revealed their biological and physiological mechanisms until this new research conducted by a British scientist was presented.
She and her colleagues found that their mitochondria, parts of human cells that respire to generate energy is super-efficient. Also, while the blood circulation within small blood vessels of the visiting mountaineers significantly slowed during the climb, Sherpas’ blood circulation remained normal.
How long do you need to live in such a highland region to be comparable with Sherpas?
Enjoy reading and learning what this study could bring about for people live on the ground.
