As the 100X4m world record falls again !

As the 22-year-old Jamaican athletic, Usain Bolt, smashed the 100m race record in lighting fast 9.58 seconds in Berlin and 200m in 19.30 seconds 2008 Beijing Summer Olympic, becoming the world’s fasted man. Scientists got shocked with big question HOW FAST CAN A MAN RUN.  Bolt’s 100 meters record in Berlin was  0.1 seconds faster than the previous one he set on 2008 Beijing Summer Olympic. Blot`s 2009 Berlin 100m record was the 18th time the record had been legally broken since an American called Don Lippincott ran 10.6 seconds in 1912, and the eighth new 100 meters record set since 1991. The 10-second barrier was broken in 1968, the 9.90 barrier in 1991, and the 9.80 barrier in 1999. Now the 9.4 barrier is in sight.

How much faster can humans run?

According to,

Dennis Bramble, professor of biology at the University of Utah “No one can really know exactly how fast a human may be able to run” further he says that “certainly, runners have been getting faster”. But as Peter Weyand, an expert in bio mechanics at Southern Methodist University, points out, our history of recorded time in sprints is relatively brief. “We have no way of knowing if humans might not have been even faster centuries or millennia ago”.

Yet as many Scientists believe,

 *We're already reaching our top speed. Man cannot run faster than 30mph, with the best at about 27mph. (Bolt’s average speed in 100m is 23.15mph)

*We have certain physiological handicaps that will always hinder us. We'll never resemble a cheetah, which can reach 70mph.

*There must be some point at which the record will never be broken; we'll surely never see the 100 meters run in 5 or 4 seconds.
