What are the skills for swimming beginners to learn to swim.
For girls like me who are afraid of water, learning to swim is really difficult. Every time I make up my mind to learn to swim, after drinking a few sips of water, I lose my confidence. Later, for a long time, under the guidance of the coach, I learned it slowly. Learning to swim is mainly to learn these skills.
First of all, you must have equipment before swimming: swimwear (choose comfortable, elastic, quick-drying, easy to wash and easy to wear and take off), swimming goggles, swimming cap, floating board (optional, depending on the coach's arrangement), back float (Optional, listen to coach arrangements). Bathing equipment: towel or bath towel, shampoo, shower gel, soap, sandals and slippers.
Breathing in water is mainly divided into holding and exhalation. If you know how to hold and exhale correctly, you don't have to worry about flooding. Inhale, lower your head, swing your arms as you exhale, then stretch your hands forward, push your legs out of the water, inhale, and then lower your head. back and forth.
The pressure of water is significantly higher than the pressure of air. It is definitely more difficult than holding water and exhaling on land. Therefore, beginners should first practice the basic essentials of holding and exhaling on land, and then practice in the water. Do not inhale and exhale immediately. You can try to become familiar with it and hold your breath.
What is rhythmic breathing? In fact, this is the so-called regular and regular breathing, without frequent or slow breathing.
Exhale through the mouth (nose) in the water. In addition to paying attention to the rhythm, you can also press the water with your hands. In children's teaching, because there is often the problem of being unable to stand at the bottom of the swimming pool, rhythmic breathing guidance is more important. The coach can regard breathing as the initial stage of breathing. (Coordinated actions: 1. Straighten your hands, merge, sink and exhale. 2. Press your hands to both sides, raise your head and inhale)
In order to make the center of gravity of the human body coincide with the center of buoyancy, the human body must first lie on a straight line, which is the longitudinal axis of the human body. The head, shoulders, chest, waist, hips, legs and feet should be on the longitudinal axis of the human body, and when the arms are stretched forward, they should also be on the longitudinal axis of the human body; secondly, press the chest to move the floating center backwards .
Compressing the chest is like pressing down on the chest and back with an invisible hand. In fact, this is to keep the chest under a certain pressure on the water. At the same time, the human body is a straight line, just like a seesaw, with one end of the straight line-the chest facing down, and the fulcrum between the chest and abdomen, so the hips and legs at the other end will rise. In addition, stretching the arms can make the body's center of gravity move forward moderately. In this way, the body can be balanced into a streamlined shape.
Relaxing while swimming means minimizing effort under the premise of moderate tension or moderate effort. So how to determine this level? To understand this level, we must first know how to use force.
There are two kinds of human movement, one is static force. This power does not change the body. The other is strength. This force causes changes in the body. For example, a weightlifter must use force when lifting a barbell, and static force when maintaining a posture after lifting the barbell. The weight of the barbell is the degree of strength. Therefore, this level is the minimum amount of work required to maintain a certain body posture.
