Sup Travellers?! We all know that Usain Bolt is a freak. His speed has been branded as inhuman because scientists have failed to understand it. His world record speed of  9.58 seconds makes Usain Bolt the fastest man on earth and up until today it has no scientific explanation. But it seems as though Physicists have unraveled the mystery of Usain Bolt's speed.....somewhat. His entire body structure makes him a model of aerodynamic perfection despite the fact that it doesn't. It may sound confusing but Read on.


According to Physicists from the European Journal of Physics, Usain Bolt uses an almost inhuman amount of energy to overcome air resistance, thanks in part to "extraordinary stride length" and "lots of fast twitch muscle fibers." Physicist, George Dvorsky, says that he's "truly a freak of nature."  Many may think that height should make you faster but it doesn't. Height makes you slower and Usain's frame of 6ft 5 inches should actually make him slower. This is why his speed was a mystery. Below the jump are some of the findings.

  1. Only 8% of the energy Bolt expended in the race was used for motion; the rest was to overcome the aerodynamic drag of his large frame, explains InsideScience
  2. His maximum power output came less than a second into the race; figure about 3.5 horsepower, or enough to power a "large vacuum cleaner," reports PopSci.
  3. His top speed came about 7 seconds into the race at around 27mph.
  4. Even without the slight tailwind he had that day in 2009, he would have busted the record with a speed of 9.68 seconds, say the physicists.
From the findings it seems as though Usain's speed is still mind boggling. The Physicists did say that it's a combination of stride length and fast twitch muscles but any idiot with a physics text book could have figured that out. Some of the findings were useful and did shed some light on the mystery of his speed. But let's just acknowledge the fact that hard work and dedication must have had a huge part to play but hard work and dedication doesn't look too good in an scientific equation, now does it? Anyway, my name is Trinikid and you've just been informed.
