Cerebral Oxygenation: Kenyan Runners Maintain High Brain Oxygenation

Cerebral Oxygenation: Kenyan Runners Maintain High Brain Oxygenation

The Kalenjin, who occupy much of the Rift Valley, are Kenya’s third largest tribe. Despite only making up approximately 12% of Kenya's population, they represent more than 75% of their country’s top runners. If you think Kenyan running couldn’t be more impressive, think Kalenjin running. “To put Kalenjin running success into perspective. Consider that 17 American men in history have run faster than 2:10 in the marathon. 32 Kalenjin men did that last October…” – David Epstein, 2014. There are many physiological factors that are believed to influence elite Kenyan runners' success, from specialized morphological features to high aerobic capacities. More recently, a new physiological mechanism was brought to light, which could be another important underlining factor for their unparalleled success.

Previous studies have...
