Top Speed of Jamaican Sprinter Usain Bolt


Usain Bolt is the fastest man in the world. The speed of this Jamaican sprinter is unbelievably fast.He is the best sprinter in history.

Jamaican sprinter Usain Bolt won his second straight gold medal in the 100 meters, finishing in 9.63 seconds. While his time was slower than the world record—9.58 seconds, which he himself set at the world championships in 2009—it was still absurdly fast. For those of us more accustomed to sitting than sprinting, to bring this feat into terms of speed, while ruminating over the biological limits of the human body, is to simply underscore the stunning nature of Bolt’s performance.

Speed is the rate at which an object moves through time. It is represented mathematically as speed = d/t (in which d is distance and t time). That means that Bolt’s speed at this year’s 100-meter competition in London was 10.38 meters per second. Since many people are more familiar with automobiles and speed limits, it might be more useful to think of this in terms of kilometers per hour or miles per hour—37.37 and 23.35, respectively. That’s faster than Google Map’s estimated traffic speed for the U.S. cities of Boston, New York, and San Francisco and government estimates for urban areas of Britain.

But even more astounding is the fact that Bolt started from a speed of zero and then had to accelerate, which means that his top speed actually was faster. In 2011 scientists at Katholieke Universiteit Leuven in Belgium used laser technology to measure Bolt’s performance in the different stages of a 100-meter race held in September that year. They found that, 67.13 meters into the race, Bolt reached a top speed of 43.99 km per hour (27.49 miles per hour). He finished with a time of 9.76 seconds in that race.

Bolt dominated the 100-meter event in London. But research has suggested that, with his body type, he probably shouldn’t even be competitive at that distance. From a biomechanical perspective, the fastest sprinters are relatively short, their muscles loaded with fast-twitch fibers for rapid acceleration. The elite sprinter is a compact athlete, not a tall and lean one. Given his size—literally head and shoulders above the other competitors—Bolt should be last off the blocks and last across the finish line. And yet he is the fastest man in the world.
