Swimming is a very good fitness exercise. It has many benefits. For example, swimming can lose weight and shape. It is a very comprehensive fitness activity. When swimming, in order to avoid sinking, you must learn the first lesson of getting started, that is, the sense of water. The so-called sense of water is the feeling of water. You must relax when swimming. , to learn to hold your breath in water, etc., let's take a look at this content. 1. Look for the sense of water, The first step in getting started, what is water sense, that is, how you feel about water. You can perceive the force of water on you, the nature of water, and the buoyancy of water on you. The most basic way to get familiar with the water sense is to contact walking in water and floating wax gourd. Try walking in water, you will find that people like walking on the ground, mainly relying on the backward friction of the soles of the feet to generate your forward momentum. In the water, it mainly relies on your upper body to push the water downwards and backwards to generate forward momentum and supplement the upward buoyancy. Although the lower limbs consume a lot of physical strength, their main function is to maintain the balance of the body and the buoyancy of the lower limbs, and contribute less to propulsion.
2. Relax The relaxation while swimming is not really relaxation, but actually moderate tension. What is moderate tension? In normal standing, sitting, and walking, there is a certain amount of effort, and this effort is moderate tension. So how to determine this degree? To understand this degree, we must first understand how to exert force? Relaxation when swimming is to reduce the effort as much as possible under the premise of moderate tension or moderate effort. There are two kinds of human force, one is static force. This force does not change shape; the other is power. This force will cause the body to change. For example, powerlifters use power to lift the barbell, and static force is used to maintain the posture after lifting the barbell; and the weight of the barbell is the degree of force. So this degree is the minimum force to maintain a certain body posture. When swimming, keep the body streamlined, that is, the body is moderately tense into a "one" shape. On this basis, plus arm and leg movements, it becomes breaststroke and freestyle.
3. Practice holding your breath in water 1. First, exercise yourself to hold your breath in the water. You don’t need to worry about being choked by the water when you hold your breath. You can fully believe in yourself. You can hold your breath easily without pinching your nose, and you can hold your breath for 20 seconds in the water. This step does not require you to move in the water, just dive into the water and hold your breath. 2. When these exercises reach 20 seconds, you can try to squat down on the edge of the pool and dive further into the bottom of the water. Because with the depth of the water, the pressure in the water is strong and the pressure on the body is high, you will feel nervous, because you can't swim, and you are afraid of choking in the water, so it is important to overcome this subconscious fear in your heart. You should like water before thinking about swimming for the purpose of exercising. You can squat in the water and feel the pressure of different depths of water. I think it is also a kind of pleasure experience in water. You can control how much you can hold your breath in water at different depths (up to 75% of your height), and that's a quick learning curve.
