Exercise combines strength and coordinated movements of the upper and lower limbs and has several positive effects of Lifeguard course near me.
Famous for being a complete physical activity, swimming is a sport in which most muscle groups in the human body work together with breathing and can allow the practitioner to master another environment , the aquatic, in addition to the terrestrial habitat.
The exercise combines strength and coordinated movements of the upper and lower limbs, aiding in injury recovery, weight loss and increased physical conditioning, among others. The practice has some styles that differ in the way the individual moves in the water, but they all have the same objective: to allow the movement of displacement in the liquid medium without the use of accessories.

WHICH IS

Swimming can be defined as an activity that performs movements in the water causing the practitioner to move, without the help of external agents, according to the professor and researcher in the area of ​​Biomechanics of Swimming at the Federal University of Ciara (UFC), Barroso Lima*.
Knowing how to swim goes beyond learning and exercising the sport’s techniques – whether in the frontal position (front), dorsal decubitus (back) or vertical -, according to the teacher, it is essential to master the balance acquired with practice and adapted breathing, in addition to to look for innovative motor solutions.

HISTORY

Cave paintings make references to the use of swimming by humans 7,000 years ago. The activity was used by man even during antiquity, as a means of survival . He built houses on the water surface – the so-called stilts – to stay safe from predators, or when he was attacked by these animals, he threw the water to escape with American Lifeguard Events.

The practice was also part of the training of warriors in Ancient Greece , who, when moving to battlefields, often had to cross waterways and, as many wore armor, ended up drowning if they didn’t know how to swim. The practice was also used to obtain food through fishing.

According to the philosopher and mathematician of the classical period of Ancient Greece, Plato , “every educated citizen is one who knows how to read and swim”. The ancient Egyptians considered swimming to be an “educational refinement” .

In Japan, in the year 38 BC, Emperor Sugam was already promoting swimming festivals. But it was in Europe, in 1800, that the first isolated events, small tournaments, of modern swimming, as we see today, began to happen.

Swimming competitions as a sport, called Pure Swimming , began in England in the mid-19th century, being part of the Olympic modalities since the first edition of the Games in 1896 — intended only for men. Female participation in the sport only materialized at the 1912 Olympic Games.

MODALITIES

The competition practice, called Pure Sport Swimming, is composed of four techniques. The expert listed each one. Are they:

CRAWL OR FREE

The technique is considered the fastest among the modalities of the sport. In it, the swimmer’s arms perform a kind of elongated S. During the entire time, the swimmer remains with the belly down.
In practice, the motor actions performed by the upper and lower limbs tend to ensure continuous propulsion.

BACK

In the style, the competitor lies on his back (supine position), while the arms alternately rotate as if they were propellers. The legs work harder in the modality, executing, on average, six beats for a complete cycle of strokes.

The alternating segmental action allows the creation of an almost continuous propulsive force, as in the crawl.

CHEST

In practice, which is compared to the style of displacement used by frogs, the competitor lies on his stomach and moves through the simultaneous movement of the arms and legs.

During the stroke, the swimmer makes the movement of pulling the water towards the chest, lifting the head to breathe, and then throwing the arms forward. The feathers, on the other hand, are horizontal, with the feet turned out, also performing simultaneous movements of bending the knees.
