Why are all blacks and whites participating in the men s 100m final, and why are yellow people rarel

It has something to do with their living environment, the tropical rainforest, the beasts are rampant, and they have to run away from the beasts at any time, so they have a strong ability to sprint! None of the whites made it to the finals, and the blacks were so explosive...

Some people say that black muscle structure is more suitable for explosive sports, such as sprinting and basketball, but I personally always disagree with this statement. When Liu Xiang won the gold medal, weren't all his opponents black? I think the main thing is that there is not too much investment in this sport on the Asian side, and then taking China as an example, it is more social factors that limit the development of sports, first of all, the popularity of sports is not enough, young people are used to engage in exam-oriented education, how can there be time to engage in sports, and then there is sports, you have the ability, it doesn't matter if you don't have money, you want to enter the provincial team and the national team, there is no door!

In this way, layer by layer, how many talents can really be discovered?

Genetic factors Black people's excellent motor genes come from higher genetic diversity, one study showed that two randomly selected individuals in Asia and Europe had an average of 6 different DNA sequences per 10,000 people, while in Africans, the average 12 out of 10,000 DNA sequences were different, that is, black people had a higher diversity of physical conditions. There are many fast-twitch muscle fibers Research revealing the relationship between genetic factors and athletic ability points out that there is indeed a mysterious gene in the human body, Actn3, which is responsible for the production of muscle proteins - promoting the formation of white muscles, a type of muscle fiber with instantaneous explosive power.

Because the physical fitness of yellow people and black people is different, black people have stronger genes, black people are very tall, black people are very explosive, and yellow people are not good at staying and explosive.

It is related to the physical fitness of the individual, because black people are very tall, have long legs, and run very fast.

The long-distance running champion is black, which is not true in itself!

Below 10,000 meters (in the track and field), it is now the world of black people, but the absolute advantage is limited to men, and women cannot be said to be black because of the social development situation and cultural customs in Africa. In the women's event, white Europeans, Japan and China in East Asia have all had good athletes.

Outside the track and field, the marathon is not an event in which blacks have an advantage, and the reasons are very complex, but I personally estimate that it is similar to swimming: black people have heavy muscles, other conditions are the same, the body weight is heavy, ultra-long-distance sports, the burden of weight is not light, and it is difficult to have better performance at the same training level. In the athletic field, the developed muscles of the black people are just taking advantage of it, but the popularity of women's events will take some time.

Now the advantage of the black endurance project, on the one hand, thanks to the congenital physical condition, on the other hand, it is also the harsh environment and the need to run often The habit of life has exercised the physical strength and will, to win the championship is the product of a combination of factors, for a long time, a single advantage is still difficult to determine the ownership of the champion alone, if your national quality is generally improved, there are many people who train, there are many athletes, and the training level is high, it can completely make up for the disadvantage of the body, Wang Junxia's generation, and Britain's Radcliffe, who was also a 39-year-old white Romanian (perhaps less watched, the marathon champion at the Olympics, I haven't noticed a black man ever won the title).

Running fast, mostly in several countries on the East African plateau (people on the plateau, many people with strong cardiopulmonary function), where many tribes live by hunting, chasing prey all year round, and exercising at least dozens of kilometers a day, on this basis, although the country is backward, but the long-distance running project is easy to find wizards, and once these people become professional athletes, they generally go to Europe to train intensively, and the level is very high, and it is easy to become world-class athletes.

The constitution of people of every skin color is different.

Generally speaking, Europeans, Americans, and blacks have better physique than Asians.

Among them, black people have the strongest explosive power and endurance, but the life span of black people is relatively short.

The muscle type of the black man is good for long-distance running, just like the Chinese play table tennis.

The reason for the very short life expectancy in Africa is that, first of all, the medical conditions in Africa are very poor, and only the larger cities have medical facilities. Second, there is widespread poverty among the African people. When they get sick, they have to work hard to bear it.

If they can't carry it, they'll fall. Third, Africa's health habits are poor. It drinks raw water, eats raw meat, does not bathe for a long time, and has a lot of bacteria and viruses.

At the end of the day, they are still poor. That's what I saw.

Why Black Africans Run Fast: Studies have shown that black athletes have fast muscle fibers that make up more than 80 percent of their muscle, compared to only 70 percent for white and yellow athletes. From the point of view of muscle mechanics, there are a lot of fast muscle fibers, and the flexion and extension of muscle contraction are large, so the explosive force will be stronger.

At the same time, muscle fibers are divided into red and white muscles according to their color. There are more mitochondria and more energy in red muscle cells, so people who have red muscle or mostly red muscle are explosive players. White muscle cells provide energy evenly and continuously, so people with or predominantly white muscle have greater endurance.

Black athletes have predominantly red muscles, which are better suited to sprinting events.

In addition, black athletes have stiff bones, can withstand large impacts, have long limbs, narrow hips, less fat, and better body extension, coordination, and flexion and extension than other races. Bolt's body shape is a good example of these characteristics: long limbs, strong feet, and good endurance at high speeds.

Over the course of his career, Robinson has won honors such as Rookie King, MVP, and World Series. In order to commemorate Robinson's contributions, Major League Baseball directly named the Rookie of the Year award "Jackie Robinson Award" and designated April 15 as "Jackie Robinson Day".

According to the researchers, humans have a history of 1.5 million years from apes to upright walkers, and Homo erectus originated from Australopithecus australopithecus in Africa, and then gradually spread from Africa to the temperate zone of Asia and the subtemperate zone of Europe. For more than 1.5 million years, human beings began as a primitive way of living by hunting and gathering, and this living environment determined that in order to survive, they must have a strong physique that can run and jump well. In such a genetic environment, blacks retained their athletic talents.

Because black people are born with a talent for running, they are very experienced.

Because black people may exercise regularly, they are more athletic, so they are better at running than other races.

This has a lot to do with the black gene, as well as their eating habits, etc., which cause them to have a strong running ability.

I think it's because they live in a special environment, so they have such a specialty.
