Then they join to form a nearly straight line, indicating the high and steady speed that he maintained for most of the race. We know that his fastest average speed, over a meter section, occurred somewhere between 50 and 80 meters, but an average speed over 10 meters is not quite what we want; we are interested in his peak speed.
Imagine that Usain Bolt was wearing a speedometer. At what precise moment was he running the fastest? And exactly how fast was that? The concept seems almost paradoxical. At any instant, Usain Bolt was at precisely one place. He was frozen, as in a snapshot. So what would it mean to speak of his speed at that instant?
Speed can only occur over a time interval, not in a single instant. The enigma of instantaneous speed goes far back in the history of mathematics and philosophy, to around B. Recall that in his paradox of Achilles and the tortoise, Zeno claimed that a faster runner could never overtake a slower runner, despite what Usain Bolt proved that night in Beijing.
And in his arrow paradox, Zeno argued that an arrow in flight could never move. Mathematicians are still unsure what point he was trying to make with his paradoxes, but my guess is that the subtleties inherent in the notion of speed at an instant troubled Zeno, Aristotle and other Greek philosophers. Their uneasiness may explain why Greek mathematics always had so little to say about motion and change.
Like infinity, those unsavory topics seem to have been banished from polite conversation. Two thousand years after Zeno, the founders of differential calculus solved the riddle of instantaneous speed. Their intuitive solution was to define instantaneous speed as a limit — specifically, the limit of average speeds taken over shorter and shorter time intervals.
Usain set the last two world records in the metres and increased the average speed from the world record set by his fellow country man Asafa Powell of This graph shows why Usain Bolt is amazing; it is the margin of his new World records. In he increased the world record by an average speed of 0. In other words Usain Bolt lowered the world record by 0. Usain Bolt is by far the fastest man on the planet at this moment in time but we cannot say for sure he is the fastest man on the planet ever.
Will there be someone faster in the future? Who can say! What if we removed these restrictions and started the timing based on a rolling start? If we encouraged him to carry on running through the finish line without slowing down like running through First Base in baseball , what would the time be? Looking at the above speed curve, if we say that Usain as ‘at speed’ when he reaches a velocity of Assuming he had a good breakfast and can keep this speed up over the entire course, maybe we trick him and put a ‘fake’ finish line 20m beyond where we really stop timing him to encourage him to keep on running!
He could, theoretcally, cover m in approx 8. This running start idea is not quite as contrived as it sounds. This is what happens in the relay race. Photo Credit: RyanTaylor That honor goes to the Cheetah Acinonyx jubatus , a large feline found in Africa and Asia.
So a cheetah can out-pace Usain, but if he had a head-start, Usain could probably out-run the animal. However, if you were to record instantaneous speed at different points throughout the race, the runner would reach a maximum speed much greater than this. Although you would expect that over a distance of m the runner will slow down after achieving top speed somewhere in the first m, Usain Bolt’s m world record time of This is because the sprinters start from a stationary position and some time is taken up in accelerating up to top speed.
In the m, the second m is covered with a running start. Over the m distance, the athlete continues to fatigue, and the average running speed over this distance is of course lower.
From there, we can gauge how fast truly fast can be. From the start, Fox News reports that Bolt reaches a speed of 28 mph. The BBC breaks down how he reaches this speed:. Bolt covered the course from a standing start at

The man runs and runs extremely fast. The legend gained fame for double sprint conquest in world record times at the Beijing Olympics, making him the first to claim both world records since fully automatic time became the norm.
Bolt is widely considered to be the greatest sprinter of all time. He was also a part of the 4Xm world record. Then, in May , Bolt crossed the finish line at a time of 9.
Then a few months later, Bolt improved his timing to 9. Bolt ran Jamaican teams over recent times have completely dominated the 4 X m relay race, and Bolt has helped greatly in their victory. Bolt has assisted the Jamaican team in winning three 4 X meters relay world records with the current WR at A large percentage of sprinting ability is determined by genetics.
For example, research has reported that runners with a higher percentage of fast-twitch muscle fibers —around 75 percent—at birth possess a higher speed potential than those with more endurance slow-twitch fiber. Although running is one of the most convenient of all sports, sprinting tends to be more technique-oriented. To improve your running speed, you should be spending a lot of time running fast. Practice, after all, makes perfect.
Sprinters also need robust muscles to help propel them forward as fast as possible. The Jamaican runner is no match for a number of animals, both domestic and wild. For example, a cheetah, the fastest land animal, can reach 70 miles per hour.
This would be roughly 45 miles per hour faster than Usain top speed of Runner’s Blueprint. Curious about how fast Usain Bolt can run? Sounds great? Who is Usain Bolt? The M relays Jamaican teams over recent times have completely dominated the 4 X m relay race, and Bolt has helped greatly in their victory. And most importantly, what can you learn from him? Your Technique Although running is one of the most convenient of all sports, sprinting tends to be more technique-oriented.
Here are some common sprinting form traits to develop: Footstrike — Aim to land on the forefoot or mid-foot as these positions tend to be more efficient for speed than landing on the heels. Good posture — Keep your head upright and in line with your body, shoulders down, and relaxed. Engage — Activate your core muscles and keep your back straight. Power comes from the core—not just your legs. Arms — keep your arms loose and relaxed at right angles while pumping your hands to shoulder level to drive them forward.
Heels — your heels should come off the ground in high arcs by almost kicking your bottom before traveling through to the front.
