Nike KD VI,Usain Bolt is a big guy as far as sprinters go, and his 6-foot-5 frame doesn't exactly make him a model of aerodynamic perfection. But as his time of 9.58 seconds in a 100-meter race in 2009 proves, he is the fastest human on the planet.Even physicists who pored over every frame of that race are wowed after translating Bolt the runner into Bolt the mathematical model for a study in the European Journal of Physics. He 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, a Cambridge physicist tells the BBC.
Or just think of him as truly a freak of nature, writes George Dorsky.Some of the eye-popping findings:
KD V,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.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.His top speed came about 7 seconds into the race at around 27 mph.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.All of which might beg the question, Is he doping? At Let'sRun.com, Robert Johnson makes a strong case for Bolt being clean. He's been busting records since he was a boy, and he may one of those rare athletes — think Babe Ruth in his day or LeBron James today — who is simply way better than his peers because of his rare physical attributes.
On Monday, Kidd revealed to season ticket Nike LeBron 11 Armory Slateholders, the Nets will be the new season opener in Cleveland. News source said the Nets will play at home against the Chicago Bulls on Christmas Day; while away the contest with the Knicks were arranged in Martin – Luther – King Day, as well as the road against the Lakers in the Local 2014 conducted on February 23. Middle of this month, the current Nets coach Kidd admitted in court drunk driving, although the Union has not made official punishment, but according to the standard Kidd will be suspended for two games, which means that Kidd will miss the first two games against the new season Cavaliers and the Miami Heat team.(Air jordans 2013)
