Why are black athletes not suitable for aqua sports?

According to evolutionary theory, the black ancestors lived mainly in Africa, because of the drought, the lack of exercise for competitive swimming, and the lack of specialized swimming pools. Even in the Amazon Basin, although some live near the water and even live on the water, because the carnivores in the water often cause harm to humans, some of them are familiar with the water, but there is a big gap between them and competitive swimming. A chronic lack of exercise is one thing.

At the same time, after a long period of evolution and accumulation, there are some differences between the muscle types of black people and other races, and the content of "white muscle" is high, which makes it outstanding in track and field, but it is not very suitable for water sports.

Black people have tighter muscle tissue, so black people have more strength, but black people have a low proportion of body fat, so their body density is large, and they are less buoyant when they enter the water, and it is not easy to do well in swimming, so we rarely see black people in swimming events. But this does not mean that black people can't swim, it's just that the selection method of the Olympics is completely based on performance, so even if black people participate, most of them will be eliminated in the preliminary round.

This is related to the proportion of the human body, due to the survival of the fittest, black people are more adapted to running due to their growth environment, and the muscle tissue of the lower body is developed, but in the competition of swimming events, the strength of the upper limbs is more important, which leads to the weak link of black people is swimming.

Because they haven't touched water. Hehe. God is fair. They're already so able to run.

Here's why:

From an exercise physiology point of view, blacks are not suitable for swimming, which is thought to be mainly due to their higher muscle ratios than other races. Scientific research by the National Institute of Sports Science has shown that whites weigh more per cubic centimeter of muscle, while blacks weigh grams, which makes blacks have to exert more effort in the water than whites to solve the problem of body sinking. In layman's terms, compared to other races, blacks are more likely to "sink" and "float" in water.

And from the data point of view, the body density of blacks is about 1% higher than that of whites, and the difference in body density of 1% can cause the difference in speed in the pool, which can be fatal in swimming competitions where gold medals are determined by seconds or even seconds. In addition, the specific gravity of black bones is about 5 to 10 heavier than that of white bones, and the heavier bones and less fat on black bones make them less buoyant in water. In this way, in the competition with white players, black players can be described as "congenitally deficient".

The performance of black people in endurance events has evolved from its origins to evolution, and black people have lived in the African highlands for a long time, which has created the maximum oxygen absorption capacity of this race, and black people are equally good in endurance events. Black Kenyan athletes have long dominated the middle- and long-distance running events, with 22-year-old Kenyan athlete Allen (who won the men's 800m run at the 24th Olympic Games; In the same year, in the World Indoor Track and Field Championships, he broke the world record in the indoor 800m run held by British athlete Coe (who had been held for many years; At the Zurich International Athletics Grand Prix, he achieved his best result. Kenyan athlete Kaluki (and Kauts, who won gold and silver in the 3000m steeplechase at the 24th Olympic Games; At the Athletics Grand Prix in Stockholm, Kaluki broke the 11-year-old world record held by Kenya's Henryrono.

Black athletes from other countries have also performed extraordinarily. Black Moroccan athlete Oita (known as the "Moroccan Express") has set five world records in middle-distance running, not only running a best time of 1500m, but also setting a world record for running 3000m. Endurance exercise is related to people's cardiopulmonary function, and it is also related to the regulation of body temperature by neuroendocrine.

Blacks have long lived in the hot tropics between the Tropic of Cancer and the Tropic of Capricorn, and have the biological advantage of heat tolerance and temperature regulation.

Badminton book hairball.

Ping pong. Gymnastics.

It is a skill-based sport, and black people have better physical fitness, and they are good at athletics.

Of course. It's also about the popularity of sports.

Badminton and table tennis are more popular in Asia than on other continents.

Tennis and other aristocratic sports.

It is better to popularize it in Europe and the United States.

So they have a lot of high-level players.

According to local conditions, the root hidden stove chooses the project according to their own physical conditions.

to get good grades.

There are not many black swimmers in the middle and high level, and the 1992 Olympic champion in the men's 100m butterfly was Suriname's black athlete Nesti, who won the men's 100m backstroke at the 1996 Olympics.

The second and third are two black athletes from Cuba, and there are some black athletes among the top athletes today

Black athletes do as well swimming, as yellow people do in athletics, there are good, but not many.

The reasons are: 1 The physical advantages of black people on land cannot be exerted in the water, their body structure is conducive to running and jumping and other lower limb sports, but it is not conducive to arm movement-based swimming, and their muscle types are also dominated by white muscle fibers, which have good explosive power but cannot last, while swimming requires strength and endurance.

2 You may ask that Kenya and Ethiopia also have a lot of long-distance runners, but they are also runs, and most of the long-distance runners are from East Africa, but East African countries are relatively poor, there are not enough swimming venues, and the swimming foundation is not good.

The fat content is low year-on-year, and it is easy to sink in the water! ~

Because blacks only have mountains and very little water.
