Why blacks run faster 10

Good physique, good body shape, strong ability to carry oxygen in the blood.

Because the fibrous structure in the middle leg muscles of the black body is different from that of Caucasian and yellow people. It's like we're long fibers and they're short fibers. Of course, the effect is different! ~~

Because blacks run fast!

Good quality, good physique, good nutrition.

Because their living environment is different from ours.

Black people run fast because they originally lived in Africa, and they all had the talent of running, and in their hearts, running became a way to make a quick fortune.

1. Kenya and Ethiopia are located in the plateau, with an average altitude of 2,500 meters, about twice as high as Lushan and Huangshan, and the people here have a strong cardiopulmonary function, it is said that the hemoglobin content of Chinese men is 12-15g l, while the black African brothers are 18g l, and the blood oxygen-carrying capacity is particularly strong, and they go up to the fifth floor in one breath without panting.

2. The explosiveness of black athletes can be attributed mainly to the higher secretion of male hormones in the body, which is 3% higher than that of whites and yellows19. These synthetic molecules were also the main active ingredients in early doping, exogenous male hormones, which were banned by the International Olympic Committee (IOC), and black athletes were the equivalent of natural doping.

3. Black athletes are good at explosive sports and have a lot to do with the composition and structure of their muscles. Muscle tissue is divided into white muscle fibers and red muscle fibers. The former is also known as the rapid movement unit, and when performing rapid explosive exercises, the main thing that gets the exercise is the white muscle fibers.

The proportion of white muscle fibers in blacks is more than 80%, far more than in other races.

4. The muscles of black people are long strips, the tension and relaxation coordination are very good, and the extremely low content of adipose tissue can also reduce the friction effect of muscles in the process of contraction and relaxation.

They say that blacks are more explosive.

Blacks are good at long-distance running because:Blacks have some unique physical characteristics that make their explosiveness advantage even more prominent.

1. During strenuous exercise, due to the acceleration of metabolism, the body temperature rises, and the ability to regulate body temperature plays an important role in maintaining the stability of the internal environment and electrolyte balance. Black players can adjust to normal body temperature faster than other race players.

2. The torso of black people is short and the limbs are long, and surveys have shown that compared to the length of the whole body, the lower limbs, especially the lower legs, are longer than those of other races. The higher center of gravity reduces the stability angle of black players, which is conducive to fast and flexible movements.

3. The slender calf is also convenient for obtaining greater limb linear speed. It is worth noting that the black man's Achilles tendon is very long and the plantar flexor muscle strength is the strongest of all races, which allows them to gain more reaction force when starting the ground, which gives them an advantage at the start.

4. The hips of black people are upturned, which increases the length of the hips and leg muscles, and produces greater contraction. Muscles that increase in length can also increase the duration of contraction forces on the legs. Such characteristics black players gain excellent sprinting ability and bouncing ability.

The natural muscle explosiveness, flexibility and endurance of black people are quite suitable for a robe! Adopt it.

Black people run fast is genetically determined, black legs are long, the center of gravity is high, the stable balance angle is small, the stride length is large, and the thin waist and narrow hips are flexible, the sense of rhythm is strong, and the hips make the hamstring muscle torque line good and explosive. This, combined with the fact that their calves are light, equates to saving 8% of energy expenditure when running.

Any physical activity is the result of skeletal muscle contraction, and the human body has more than 600 skeletal muscles, accounting for about 40% of the body weight. Skeletal muscles are made up of a mixture of different muscle fibers, which can be broadly divided into two categories.

One type of contraction is slower, called slow muscle fibers, and one type of fast muscle fibers is fast-muscle fibers. Endurance athletes tend to have a higher percentage of slow-twitch fibers, while non-endurance athletes have a higher percentage of fast-twitch fibers than those who do not play sports.

The fast-twitch muscle fibers of blacks are as high as more than 80% of the muscle ratio, while the whites and yellows are only 70%, and the muscle fibers can be divided into red muscles and white muscles.
