London: A pair of very symmetrical knees may be behind the record-breaking speed of Jamaican sprinter Usain Bolt, the world's fastest man, a new study suggests. Researchers from Northumbria University, United Kingdom, found that the key to sprinting could be all in the similarity of your kneecaps.
They came to the conclusion after investigating the knees of Jamaicans, believed to be the finest sprinters in the world. In 1996 they measured the width of the knees of 300 children aged about eight. A decade later they measured their knees again, then in 2010 they asked them to compete in a sprint.
Only 163 of the original sample stayed with the study until 2010, but those who did had more symmetrical knees -implying that knee symmetry is either an indicator of diligence or of a willingness to sprint, 'The Times' reported. Among those who did sprint, speed was also correlated with symmetry.
