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.
