Sanya monkey swimming skills, why is the road to human swimming so difficult?

Science Fiction Network September 1st (Wang Xiuxia) Recently, Sanya residents shot a monkey swimming in the sea. The monkey's gas is not long. You can swim in the sea for a long time without breathing, and the level of swimming is first -class. Many people are envious of this scene. Many mammals are born to swim, but some humans have learned for two or three months. Why is the road to human swimming so difficult?

In fact, monkeys do swim, but the water nature is not very good, and most of them are not good at swimming. In addition, the monkey's swimming skills are not inherent. Although they have high IQ and flexible limbs, they also need the acquired learning to master this book. Like monkeys, humans are not good at swimming, which is mainly determined by human body structure.

The first is the position of the nostrils. Most of the faces of the long -lasting animals are flat, so the position of the nostril opening is located on the same side as the abdomen, that is, the nostrils are mostly downward.

For animals walking with limbs, they do not need to change their posture, which is basically the same as when walking on the land. And their nostrils are relatively high. As long as they look up slightly, the nostrils can be revealed to breathe, and swimming naturally becomes very easy. The primates are different. After entering the water, the nostrils will enter the water. If you do not master special technical actions, you will not be able to exhale smoothly, and swimming will become difficult.

In addition, the size of buoyancy. From a physical perspective, the most important thing when swimming is buoyancy. In order to get a larger buoyancy, the area of ​​contact with the water surface must be increased. But human hands and feet grow from both sides of the body and below, and the buoyancy is less buoyancy during swimming. To meet the two conditions: "floating" and "swimming" at the same time, the only choice is to lie on the water horizontally. However, in this posture, even if the neck is twisted back to 90 °, it still cannot lift the water. Therefore, when human beings swimming, they either carry the entire upper body out of the water (swimming in breaststroke butterfly), or twist the body to make the nose higher than the water surface (free swimming). These are technical actions that need to be mastered through training, and it is impossible to be born.

The backstroke seems to be a good choice for humans. It does not seem to master a lot of swimming skills, but the opening of the nostril when swimming must be kept in a state of parallel to the water. As long as there is a little waves, the water splash will splash into the head of the head, which is very dangerous.

Swimming is not easy, it must be mastered by gradual training, and rashness is irresponsible to life. Be sure to cherish life and go to the water safely.
