What is swimming?

We explain everything about swimming, its history, the styles that can be practiced and its health benefits.

What is swimming?

Swimming is the recreational or sports practice of movement and displacement on water , using only the arms and legs of the human body. It is a technique, also, that is learned as a survival method (in fact, it is taught in numerous educational curricula), and that is practiced as an exercise given its multiple benefits to the body.

Your practice can be competitive or merely recreational . As a formal sport it is one of the most practiced in the world, included in the Olympic disciplines and carried out in swimming pools of different lengths (50, 100, 200, 400, 800 and 1500 meters). Specific swimming techniques are known as styles and have particular names .

Swimming is possible because the human body is slightly less dense than water, so it always tends to float. Our relationship with water is very particular, despite being terrestrial beings, since at birth they extract us from a totally submerged environment such as the mother’s womb.

In fact, babies show an innate tendency to swim and certain diving reflexes, such as automatic breath containment , decreased heart rate and reduced circulation to the extremities (it is the reflection of mammalian immersion ).

  1. Swimming history

Swimming has been practiced since time immemorial, and there is evidence of his knowledge in cave paintings over 7,000 years old . It is also mentioned in texts from later times, such as 2,000 a. C .: the Odyssey , the Iliad , the Bible , etc.

However, the first book on swimming was written in 1538 and is attributed to Nikolaus Wynmann, German language teacher: The swimmer or a dialogue in the art of swimming .

  1. Importance of swimming

Swimming is much more than a sports practice, it is also a skill and a technique that can often represent the difference between life and death . A good swimmer is more likely to survive certain maritime accidents, or falls overboard (if he is conscious and in full power).

On the other hand, swimming is one of the most popular sports practices in the world. It brings a lot of benefits to the respiratory and circulatory system of the human being, as we will see later.

  1. Styles

In the butterfly style both arms move forward together.

There are numerous swimming styles, some personalized or of little use, but generally speaking of four main styles, which are distinguished in competitions and are endorsed by the International Swimming Federation:

  • Chest or breaststroke style . Also known as “frog style”, because the human body resembles movements of certain amphibians , it consists of floating upside down with arms pointing forward and legs slightly bent. The head is kept out of the water to take air and then the arms move in a circle under the water, pushing the body forward as the movement is imitated with the feet, shrinking and stretching at the same rate.
  • Crol or free style . This style requires that the swimmer be straight, lying on one arm that is submerged straight into the water, while the other emerges with the elbow bent and the palm extended down, ready to enter the water. The head is shown on its side to take a breath, which is expelled when the torso is submerged and rotates to repeat the movement but with the other arm. Meanwhile, the legs move, relaxed, with pointed toes and feet inward, giving swinging kicks.
  • Back or back style . A style essentially similar to the crol, but face up, with the back submerged in the water, moving one arm in the air with the palm of the hand coming out from under the leg, while the other drives the body into the water.
  • Butterfly . A variation of the chest or breaststroke style, in which both arms move together forward and backward under water, driving the torso forward, continuously and accompanied by an undulating movement of hips, which dips the head upon entering to the water and culminates with a kick called “dolphin” because of its similarity to the swimming of these animals, using their feet together.
  1. Health benefits

Swimming has both physical and psychological health benefits, since it is one of the most complete sports practices known, strengthening the almost complete muscles of the body and stimulating mental coordination and memory . It is known that the usual practice of swimming as an aerobic sport helps with:

  • The decrease in blood pressure and fat burning , since the body must lose twice the calories to keep warm : by the exercise performed and by being submerged in a colder liquid.
  • Improves and strengthens the system heart and vascular , as the heart undergoes a continuous and coordinated with breathing further increasing lung capacity athlete.
  • Relax the muscles by mobilizing almost all the muscles of the body in a coordinated way, without fixed positions for too long.
  • In the lack of impact as land sports, strengthens muscles without subjecting it to the stress of gravity .
