Swimming tips can be learned in five minutes.

Many people want to lose weight by swimming. According to research, the energy consumed by exercising in water can be 20 times higher than that consumed by exercising on land, so more and more fat people have joined this sport. But there are many beginners who can’t swim. In fact, there are many swimming skills. After learning these skills, it is no longer difficult to learn how to swim.

Swimming skills

1. Breathe

Breathing in water is mainly divided into holding your breath and exhaling. If you master how to hold your breath and exhale properly, you will not be afraid of flooding. Inhale, lower your head, swing your arm when exhaling, then stroke your hand forward. When kicking, jump out of the water, inhale, and then lower your head. Cycle back and forth.

The pressure of water is obviously higher than that in air. It is definitely much more difficult to hold your breath and exhale in water than on land, so beginners should practice the basic essentials of holding your breath and exhale on land first, and then practice in water. Don’t inhale and spit it out immediately. You can try to get familiar with holding your breath.

2, rhythmic breathing

What is rhythmic breathing? In fact, it is the so-called regular and rhythmic breathing, without frequent or slow breathing.

Exhale through the mouth (nose) in the water, in addition to paying attention to the rhythm, you can cooperate with the action of pressing water with your hands. In the teaching of children, because there is often a problem of not standing at the bottom of the pool, the guidance of rhythmic breathing is more important, and coaches can regard breathing as the initial stage of ventilation. (Coordination action: 1. Keep your hands straight and merge, sink and exhale. 2. Press your hands to both sides to let your head rise and inhale.)

3. Balance

To make the center of gravity of the human body coincide with the floating center, we must first make people in a straight line, which is called 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 make the floating heart move backwards.

Pressing the chest is like an invisible hand pressing down on the back of the chest. In fact, it keeps the chest down to keep a certain pressure on the water. At the same time, the human body is a straight line, just like a seesaw, one end of the straight line-the chest is down, and the fulcrum is between the chest and abdomen, so the hips and legs at the other end will float up. Also, stretching your arms forward can move the center of gravity forward moderately. In this way, the body can be balanced and streamlined.

4. Relax

Relaxation in swimming is to minimize exertion under the premise of moderate tension or moderate exertion. So how to determine this degree? To find out this degree, you must first know how to exert yourself.

There are two kinds of human exertion, one is static. This kind of force will not change the shape; The other is motivation. This kind of force will cause the body to change. For example, weightlifters use power in the process of lifting barbells, while static force is used to keep the posture of lifting barbells; And the weight of the barbell is the degree of exertion. So this degree is the minimum force to maintain a certain body posture.
