Why are international track and field events usually special events for blacks?

When we discuss this issue together, the most ridiculous thing is that there are so many lions and tigers living in Africa every day that they will be eaten if they don't run faster, so they will run as hard as they can, and they will run faster after a long time. Africa has little water except sand, and even drinking water is a problem. If you come swimming with water, you can't swim without touching the pond all your life.

Of course, this is an absurd statement. Not all black people live in Africa all day. On the contrary, African blacks don't run very fast, and American blacks run faster than rockets. It is true that sprinting is good for black Americans, but marathon is good for black Africans.

Black people can dive into the slag if they can't run well, but we yellow people are just the opposite. We haven't produced a Liu Xiang in a hundred years, but we have many talents in swimming and diving. It is said that these differences are related to racial differences.

Black athletes are good at explosive sports, which is closely related to their muscle composition and structure. Muscle tissue is divided into white muscle fibers and red muscle fibers. The former is also called fast moving unit. During the rapid and explosive exercise, it is mainly white muscle fibers that get exercise. The proportion of white muscle fibers in blacks is over 80%, far exceeding that of other races. Moreover, the black muscle is long and has good relaxation coordination, and the extremely low fat tissue content can also reduce the friction effect of muscle during contraction and relaxation.

In addition to muscle function, blacks also have outstanding thermoregulation ability. During strenuous exercise, due to the acceleration of metabolism and the increase of body temperature, the ability of body temperature regulation plays an important role in maintaining internal environment stability and electrolyte balance. This is also a big advantage of black people.

In fact, these words are really elegant and many people don't understand them. Generally speaking, I don't know if you have noticed that black people's asses are all upturned, especially black women, whose asses are really unusual, and I don't know where to buy jeans that suit them after living in China for so long. The black buttock inclines upward, which increases the muscle length of buttock and leg and produces greater contraction force. Muscle with increased length can also increase the action time of contraction force on legs. This feature enables black chess players to obtain excellent sprint ability and bounce ability.

To put it bluntly, as far as physical quality is concerned, we are naturally inferior to them. They have big hips and long legs, but they also have shortcomings, that is, they are not suitable for sports that require physical skills such as swimming and diving, such as table tennis, badminton and gymnastics, and they rarely see black people.
