How to swim without sinking

How to swim without sinking

Swimming is a very good fitness exercise and it has many benefits. For example, it can help you lose weight and shape your body. It is a very comprehensive fitness activity. When swimming, in order to avoid sinking, you must learn the first lesson, that is, water sense. The so-called water sense is the feeling of water. When swimming, you must relax, learn to hold your breath in water, etc. Let's take a look at the content in this regard.

1. Look for the feeling of water.

The first step to get started is to understand what water sense is. It is your feeling towards water. You can sense the force of water on you, the properties of water, and the buoyancy of water on you. The most basic way to get familiar with the feeling of water is to practice walking in water and floating on winter melon.

Try walking in water and you will find that people prefer walking on the ground, relying mainly on the backward friction of the soles of the feet to generate your forward momentum. In the water, you mainly rely on the downward and backward thrust of your upper limbs on the water to generate forward momentum and supplement the upward buoyancy. Although the lower limbs consume more physical energy, their main function is to maintain body balance and the buoyancy of the lower limbs, and their contribution to propulsion is relatively small.

2. Relax

The relaxation while swimming is not real relaxation, but actually moderate tension. What is moderate tension? Normal standing, sitting and walking require a certain amount of effort, and this effort is moderate tension. So how do we determine this degree? To understand this degree, we must first understand how to use force.

Relaxing while swimming means reducing the effort as much as possible while maintaining moderate tension or exerting moderate effort. There are two kinds of human force, one is static force. This kind of force will not cause the shape to change; the other kind is dynamic force. This application of force will cause the body to change in shape. For example, the process of a weightlifter lifting a barbell uses dynamic force, and the static force is used to maintain the upward posture after lifting the barbell; and the weight of the barbell is the degree of force. So this degree is the minimum force required to maintain a certain body posture.

When swimming, the body remains streamlined, that is, the body is moderately tense to form a "one" shape. On this basis, with the addition of arm and leg movements, it becomes breaststroke and freestyle.

3. Practice holding your breath in water

1. First, train yourself to be able to hold your breath in water. Don't worry about being choked by water while holding your breath. Fully believe in yourself. You can hold your breath easily without pinching your nose with your hands. You can hold it in water for 20 seconds. This step does not require you to move in the water, just dive in and hold your breath.

2. When you reach 20 seconds of these exercises, you can try squatting down at the edge of the pool and moving your body further toward the bottom of the water. As the water gets deeper, the water pressure becomes stronger and the pressure on your body becomes greater. You will feel nervous and because you can't swim you may be afraid of choking on water. Therefore, it is important to overcome this subconscious fear in your heart. You should like water before you think about swimming to achieve the purpose of exercising. You can squat in the water and feel the pressure of water at different depths, which I think is also a kind of underwater pleasure experience. You can control how long you can hold your breath at different depths in the water (no deeper than 75% of your height), so it's quick to learn.
