Sprinting velocity is a function of step length and step frequency. Usain Bolt ran at 12.4 m/s in his quickest phase of his world record performance in Berlin in 2009. To run 100m in under nine seconds, a human's maximum velocity would need to be around 13.2m/s. No one has ever done this as no one else has ever been able to touch 11 seconds for the 100m distance.
The fastest man ever to run 100m in under 10 seconds was Carl Lewis who did so in 9.98 seconds in 1988. He subsequently went on to become one of the most successful athletes of all time, winning five gold medals at the Barcelona Games in 1992.
There are two types of speeds in athletics: top speed and average speed. Top speed is the highest rate of travel that a body can achieve during an athletic event. This speed is determined by how fast a body can produce power through its muscles without wasting energy. Average speed is defined as total distance covered divided by time taken to cover that distance. This type of speed is dependent on how long it takes a body to reach top speed after starting from a standing position.
It is possible to run 100m in under nine seconds if you start from a standing position. The current men's world record is 8.01 seconds, set by Usain Bolt in Berlin in 2009.
About 13.2m/s To run 100m in under nine seconds, a human's maximum velocity would need to be around 13.2m/s. Such pace would necessitate step lengths of 2.85m and step frequencies of 4.63Hz, both of which are "moderate" increases above Usain Bolt's figures. A human could manage such speeds with ease because our bones and muscles were designed for running, but many athletes who try to match them do so at the risk of injury.
The fastest man on earth today is Usain Bolt. He can run 100 meters in under 10 seconds - almost 3m/s. But this amazing speed comes with a price. The faster you run, the more stress your body is under. Your legs and feet suffer as well as your lungs and heart. In fact, running slows most other activities of daily life including standing up after sitting down, lifting objects, and even sleeping!
In order to run faster, you need to increase your stride length and frequency. This will produce greater distances covered with each step taken. So how far can you run if you take 12 steps per second? That's about 55km or 34 miles!
The average human being can run for about 15 minutes before he or she needs to rest. But there are people who have been reported to have ran for nearly two hours without stopping.
Usain Bolt's 100-meter sprint in London was the fastest in Olympic history, running more than 23 miles per hour for 9.63 seconds. Marathon runners reach half of Bolt's pace after running for two hours. A moderate walker can maintain this pace for one mile. Fastest marathon runners have reached almost exactly the same speed as Bolt, but they have done so over longer distances.
The average person walks at about 2.5 mph. Sprinting speeds exceed 10 mph.
Olympic athletes are human machines that can run faster than most people think. But even the best runners on the planet can't go as fast as a cheetah, which can reach speeds up to 50mph.
Cheetahs use large muscles in their legs and back to propel them through the air when chasing their prey. Because humans don't need to chase our food, we don't have these muscles and are therefore slower than cheetahs when running from danger.
However, we do have another kind of muscle that allows us to run fast: cardiac muscle. Our heart is made up of muscular walls called ventricles that squeeze tightly during each beat. This contraction sends blood out into our body while at the same time pulling in oxygen from our lungs via small tubes called arteries.
So far, the quickest time has been around 27 1/2 miles per hour, which sprinter Usain Bolt achieved (briefly) shortly after the midway of his world-record 100-meter dash in 2009. The strength of our bones and tendons most likely does not enforce this speed restriction. Humans can easily accelerate to velocities much higher than this if necessary.
In fact, scientists have calculated that a human body could be accelerated to nearly the speed of light (roughly 930,000,000 mps) without any apparent risk of injury. However, such high speeds would require objects to be removed from their normal path, which is impossible using only human muscles.
The fastest man alive, American Jesse Owens, held the absolute top speed record for almost 20 years. He estimated his maximum speed was about 1,070 miles per hour (1,742 km/h), but experts now believe he may have underestimated himself by as much as 50 percent. Regardless, this still puts him well below the theoretical limit.
Owens' record was recently surpassed by South African Andre Singer. On August 4th, 2008, Singer broke his own record, reaching 1,071 miles per hour (1,744 km/h). He remains the highest-ever ranked male athlete by the Guinness Book of World Records.
During a sprint The quickest of us can sprint 100m in between 13 and 14 seconds at a pace of 15.9 mph. This means we can cover 100 metres in less than half a second! We call this speed because it's faster than walking but not as fast as racing.
In order to keep up this speed for 100 metres, you need to be able to lift about 50 pounds above your head and move yourself with enough force to overcome your own inertia. This is easy if you're using your muscles instead of your body weight, but even athletes who train daily cannot maintain this level of strength over long distances.
The fastest men have been known to go under 11 seconds, but they are very rare. To achieve this speed, they use prosthetic limbs that are designed for maximum efficiency in terms of muscle mass used per unit of time. These devices are usually powered by springs or motors so they can produce power continuously. Other factors such as technology used to develop these limbs also play a role in determining how fast they can go.
Men who run faster than 100 m in under 12 seconds probably use drugs that are banned from most competitions (including the Olympics). Research studies have shown that steroid users tend to run slower than those who don't take any drugs.
Usain Bolt ran the fastest human running speed ever recorded at 44.72 km/h (27.8 mph) between 60 and 80 meters of the 100 meter sprint at the World Championships in Berlin on August 16, 2009. (Bolt's average pace for the race was 37.58 km/h, or 23.35 mph.) The previous record was 3.78 seconds held by Roger Bannister who broke the 4-minute mile barrier in 1954.
In terms of distance run in one hour, this record stands at 12 miles (19.32 kilometers). The current indoor record is 7 minutes and 59 seconds set by Dennis Scholz of Germany in 1989. The outdoor record is 13 miles (20.32 kilometers) set by Bill Bradley of the United States in 1973.
Bolt has also held the records for highest number of consecutive victories in the same event with seven wins out of eight races from 2003 to 2009. His final competition was the 2009 World Championships where he not only broke the existing record but also won his seventh gold medal. The American Carl Lewis holds the record for most gold medals with nine.
Running is a part of everyday life for Jamaicans due to its importance in school sports. In fact, running is such an important part of Jamaican culture that when someone wants to show honor or respect they will often run a race them or even challenge another person to a race.
