The benefits of swimming is known to all.But each style is useful in its own way.
Take, for example, brass.Swimming "in the frog," as popularly called brass, - perhaps the most ancient style of competitive swimming for a long time, the former basic technique in Europe.Swimmer makes simultaneous horizontal strokes arms and legs, reducing and spreading them like a frog swimming - hence the popular name.The head at the same time can be immersed in water, and can remain above water.
Brass was included in the Olympic program in 1904 already.In the first competition swimmers carefully kept his head above water (the "classic", "orthodox" breaststroke).However, in the struggle for the speed of the athletes were trying to overcome most of the distance underwater, why in 1957 "diving breaststroke" and was banned.In 1960 Olympic medalists American William Mulliken and Japanese Yoshiko Osaka found a new way to speed up the movement of water breaststroke: it needs at arm stroke to keep the person under water, and
As for the health benefits, it is the breast stroke in the first place are actively used as a recreational diving.Doctors recommend all breaststroke, but instructors in pools - mostly people with no special physical training, which need not to overload the muscles, and only "to start."
Anyway breaststroke help develop uniform shoulder girdle (triceps, trapezius muscle back, deltoid), arms and leg muscles (especially well-tightens the inner side of the thigh), to improve the shape, correct posture, take a deep breath and correct.Brass is ideal for the recovery of the Achilles tendon and leg muscles strengthening or development of the hip joints.
Doctors recommend swimming "diving breaststroke", dropping her face in the water, and at the serious problems with the back to get a better stretch the spine and arch it too much.
Brass is also very useful for pregnant women: the spine and abdomen relax ligaments and muscles of the legs and crotch become stronger and more flexible, which subsequently facilitates childbirth.Men breaststroke makes for prostatitis.
Kroll - the fastest way to move in the water, and therefore the most beloved athletes.When advertised competitions in swimming freestyle, most athletes prefer it Krol.So the "free style" swimming and crawl in sports - the same thing.
believed that crawl swimming has evolved from a voyage on the side - just the beginning of the row and the second hand.Swimmer in turn plunges into the water a little bent at the elbows in front of the shoulders, making the long and strong stroke, gradually straightening the arm, brings her out of the water at the hip.Legs with make up and down movement.Professionally compete in this style swimmers began in the early XX century.Then, in one cycle of movement of the arms athletes performed just two feet movement (the so-called two-shock or "Australian" crawl).Soon he was slightly modified by increasing the number of kicks to four and six.
In the context of rehabilitation crawl gives more load on the muscles than brass, so the trainers and doctors recommend to learn this style of navigation immediately.Particularly increases the load on the arm and shoulder girdle.Very fast crawl helps the formation of a thin and flexible waist.Again rabbit undoubted benefits to the respiratory and circulatory systems.At the same time, serious problems with the spine crawl on the chest, according to some experts, may be contraindicated.
