Adults generally learn to swim for about ten class hours, with one class lasting 60-90 minutes. When learning to swim, it is best to have a professional swimming coach to guide you and make faster progress.

Precautions:

1. Find a good swimming pool. There is light, good ventilation, guaranteed water quality and low price.

2. Find a responsible coach.

3. Complete the whole swimming course systematically and completely, and don't skip class.

4. Believe in yourself, learning is not your own problem, but the coach's level is not enough.

5. Pay attention to the mastery of basic movements, the breathing of breaststroke, the relaxation of crawl, the integrity of various movements and the freedom of movements, which are the necessary abilities to learn swimming and swimming for a long time.

6. Ask more questions, observe more, and record your own swimming video conditionally, so it is easy to find the problem.

7. Practice more, which is the most important thing. Combining 5 will get twice the result with half the effort.

8. Don't swim alone. Go swimming with at least one good swimmer. If you don't have a partner who is good at swimming, at least go swimming with several other people.

9. Don't start learning to swim in running water. If you learn to swim in the sea or river, you need to pay more attention to the flow of water. If you must learn this swimming style, try to make sure that the person with you knows what he or she is doing.

10. Keep it within the depth you can bear. When you learn to swim for the first time, don't venture into too deep water. If something goes wrong, you can at least stand up and breathe.

1 1. Don't swim in bad weather. There should be no problem swimming in light rain, but if you see or hear a storm warning, you should leave the water immediately. No matter how well you swim, you must abide by this rule.

12. Don't swim in cold water. Stiff limbs or cramps may suddenly appear in cold water.

Swimming skills:

Tip 1: relax.

Relaxation in swimming is not real relaxation, but actually moderate tension. At this point, you may be at a loss, so let's first find out what moderate tension is. Normal standing, sitting and walking have a certain amount of force, and this force is moderate tension.

Relaxation in swimming is to minimize exertion under the premise of moderate tension or moderate exertion. So how to determine this degree? To understand this degree, you must first know how to exert your strength. There are two kinds of human power: one is static. This force will not change shape; The other is motivation. This force will cause changes in the body. For example, weightlifters use strength in the process of lifting barbells, but static force is used to maintain the posture of lifting barbells after lifting barbells. The weight of barbells is the degree of exertion. So this degree is the minimum force to maintain a certain body posture.

Tip 2: Breathe.

Breathing in water is mainly divided into holding your breath and exhaling. If you master how to hold your breath and exhale correctly, you won't be afraid of floods. Inhale, bow your head, swing your arms when exhaling, and then paddle your hands forward. When kicking, jump out of the water, inhale, and then bow your head. Circulation, this is the correct breath holding and exhalation.

The pressure of water is much greater than that of air. Holding one's breath and exhaling in water are not as relaxed and natural as on land. If you practice on land first, students will adapt better first. The longer you hold your breath, the more helpful it will be to learn other movements in the future, but you should practice slowly and don't spit it out immediately after inhaling.

Tip 3: Balance

The water balance mentioned here means that people should keep streamlined in the water, which is the word "one". If swimming is a "dog planing" or something, it is not suitable. As we all know, the human body has weight, and one center of gravity is in the lower abdominal cavity. When people are in the water, the water will generate buoyancy for people, and this buoyancy is also central, so we call it floating heart. So, where is this floating heart? The lungs in the human body are like "fish gizzards" in the belly of a fish, and people's floating heart is in the chest. When people lie prone in the water, in the natural state, the center of gravity is in the lower abdomen, while the floating heart is in the chest, so the legs will sink and the balance of the body cannot be guaranteed.
