Usain Bolt’s stunning world record in the Olympic 100-metre final is still a long way from how fast the human body can go, according to a study by a U.S. professor.
Shortly after Bolt ran 9.69 seconds in Beijing, Stanford University biology professor Mark Denny set out to estimate just how fast humans will be able to run.
He concluded that male sprinters could eventually get the 100 record down to 9.48 seconds and women could run the distance in 10.39.
“My results … tell us that speed has limits, but not what accounts for these limits,” writes Denny, whose conclusions were published last week in the Journal of Experimental Biology.
Bolt surely could have gone faster at the Olympics in August.
The tall Jamaican slowed down over the race’s final metres and even banged his fist off his chest in celebration before crossing the line three hundredths of a second faster than the record he had set a few months earlier.
In September, Norwegian physicist Hans Eriksen analyzed TV footage of the Olympic final and estimated that Bolt could have run 9.55 seconds if he had not slowed down.
The women’s record in the 100 is 10.49, set by the late Florence Griffith-Joyner in 1988. But Denny used 10.61 seconds in his study because of “compelling evidence that the (10.49) race was wind aided.”
Denny used historical records dating back to the 19th century to track the progress of speed in humans, horses and dogs. He found that speeds in horses and dogs at the major races in the United States and Britain peaked, mostly in 1970s but some earlier, while most of the human races had not.
