Who is the fastest person in the world 2022?

Fred Kerley, a 27-year-old American athlete, became the fastest runner on the planet at the moment when he finished with a time of 9.86 seconds at the 100m track at the 2022 World Athletics Championships.

However, it is quite reluctant to call Kerley in the way that the whole sports village has described Usain Bolt. The "world's fastest runner" in 2022 is behind the "fastest runner in the world" in history by nearly 0.3 seconds.

Usain Bolt's Limit

In 2009 in Germany, Usain Bolt created a milestone in the history of human development when he finished the 100m World Championship with a time of 9.58 seconds. From then on, "9.58 seconds" became a symbolic number for human breakthrough, the limit of speed…

After 13 years, the village of speed athletics still has not appeared a name that can keep up with Usain Bolt's running. In 2017, in the last world tournament that "lightning" still attended, Justin Gatlin surpassed him to finish first with a time of 9.92 seconds.

Two years later, Christian Coleman improved significantly when he won with a time of 9.76 seconds. But then after 3 years, the time to become the fastest runner on the planet increased to 9.88 seconds. Then, Marcel Jacobs won the Tokyo Olympic gold with a time of 9.80 seconds.

Why does Usain Bolt's record still stand?

Who is the fastest person in the world 2022?

With the development of science and technology, why does a record of Usain Bolt last so long? That is a question that has been asked for the past 10 years and has not yet been answered.

Even the scientific world once hypothesized that ... scoliosis from a young age turned Bolt into a monster. Bolt's spine is slightly curved to the right, making his legs unequal in length, making it harder for sports scientists to explain Bolt's speed.

Since 2010, many major universities in the West have studied the human ability to surpass Bolt's record. Professor Alun Williams of Manchester Metropolitan University has identified 23 genetic traits that can improve athletic performance. Accordingly, the probability that a person has a perfect genome is 1 in 1.212 trillion.

Of course, that is the probability of finding an athlete who is "perfect in every sport". To find someone faster than Usain Bolt is not that difficult, genetically. Some other studies suggest that human muscle strength is enough to motivate us to run at a speed of 65km / h, equivalent to running 100m in just 5.54 seconds.

Besides Bolt, there are still records that have not been broken

In fact, Bolt's record of running 100m and 200m (19.19 seconds, also set at the 2009 world championship) has not been around for long in the athletics village. In the women's track, the record set by Florence Joyner has existed since 1988 (10.49 seconds in the 100m and 21.34 seconds in the 200m).

The current longest standing outdoor track and field record is in the women's 800m track, set by Czech athlete Kratochvilova in 1983 and so far no one has surpassed.

In contrast, marathon records are broken every few years (for men, eight records have been set in the past 20 years).

Expectations for the new Usain Bolt

Recently, the athletics village found a new Usain Bolt, that is Erriyon Knighton, the American boy who broke the U18 age record on Usain Bolt's 200m run when he was 17 years old. Not long after that, Knighton surpassed his own record with a time of 19.49 seconds.

This number is only slightly worse than Bolt's 19.19 seconds record. This year is only 18 years old, if developed in the most perfect direction, Knighton is capable of surpassing his senior.
