Tobias, gener eller genetisk disposition är i allra högsta grad en del i det här.. Vi ser ju olika ut här på jorden.
En dansk studie från 2000 lät Kenyanska skolpojkar träna i 3 månader och sedan fick dom träna tillsammans med den danska superstjärnan Thomas Nolan och de hade inga problem att springa jämt med honom.
"A 2000 Danish Sports Science Institute investigation reproduced the earlier study, giving a large group of Kalenjin boys three months of training and then comparing them to Thomas Nolan, a Danish track superstar. When the Kalenjin boys trounced him, the researchers -- who had also conducted a number of physical tests and compared them against established human averages -- concluded that Kalenjins must have an inborn, physical, genetic advantage. They observed a higher number of red blood cells (which lent new credence to the theory that elevation makes their bodies more effective oxygen-users) but, in their conclusions, emphasized the "bird-like legs" that make running less energy-intensive and give their stride exceptional efficiency."

"In 1990, the Copenhagen Muscle Research Center compared post-pubescent schoolboys there to Sweden's famed national track team (before Kenya and a few other African countries began dominating international racing events in the late 1980s, Scandinavians were the most reliable winners). The study found that boys on the high school track team in Iten, Kenya, consistently outperformed the professional Swedish runners. The researchers estimated that the average Kalenjin could outrun 90% of the global population, and that at least 500 amateur high school students in Iten alone could defeat Sweden's greatest professional runner at the 2,000-meter."
