Kroll - a way of sailing on the chest and back.Commits an alternate mahi-arm stroke, and sliding the feet and moving apart.If comparisons, the hands will resemble the wings of the mill or impeller steamer and legs - ordinary scissors.
When swimming the crawl on his back going on almost the same - Mahi hands and movement "scissors" - legs.Here, however, the hands move out of his head (in the opposite breast).
When swimming the crawl and stretch the body must be placed at the water surface.Immersion pelvis occurs so that the feet remain under water.The head is lowered into the water, the view is directed forward and downward.As a swimmer to do grebkovyh movement and inhale the air, he shakes his body along the longitudinal axis to the right and to the left.
footwork performed up and down (
if we take the vertical plane).Getting these movements occur at the hip, continued - in the lower leg, and complete their biting impact of the foot on the water, by which a swimmer moves forward.This first leg straightened at the knee joint, and then - in the ankle.All movements of the feet should be performed rhythmically, but freely.
hand movements and breathing
As for the hand movements, they can be divided into two phases.First stroke is performed in water, then - Bringing the water.Hand dipped in water, slightly bending the elbow and turning the palm downward.This hand should go down in front of the shoulder.
Swimming crawl - is the observance of the sequence of dives: brush - upper arm - shoulder.After almost fully extended arms in the water, go to the grebkovyh movements.Brush swimmer captures water and arm bent at the elbow, rowing the surface forms.When it's the main part of the stroke, the elbow leading to the body, and quickly move the brush back.In the final stage of the hand is straightened, brush passes near the hip.
plays an important role Bringing hands over the water.First, raise the arm, then his shoulder and hand.Bent at the elbow arm freely sneaked over the water.Sami grebkovyh hand movements are done at a time - when the end stroke with one hand, the second part of the water.
properly crawl - it means even breathe properly.The air inhaled by turning the head to the right or to the left, at the end of the stroke arm.After inhaling the head should be returned to its original position.The exhalation is done when a person falls into the water.
