In the swimming technique – a crawl on the chest, the main source of pulling power is the arm stroke. Moreover, the traction force differs depending on the skill level of the athlete himself.

Phases included in the arm movement cycle:

Support (capture of the water surface) . The arm makes a supporting, sufficiently powerful movement forward and downward with a bend at the elbow and a quick transition to the position that is necessary for the main stage of the stroke. The support phase should be completed with a relatively rigid fixation of the joints and holding the elbow over the hand;

Main body (pulling up and pushing off) . It is carried out by adduction and extension of the shoulder, at this time the arms also bend and unbend in the elbow region. This stage involves the creation of the main thrust to help move forward. To implement the main stage of the stroke, it is necessary to bend the arm at an angle of 90-100 °, while the hand movement is performed under the longitudinal axis of the body. At the moment when the stroke is performed, you need to close your fingers and open your palm. The initial stage of the stroke: the elbow is directed to the side and slightly back. Then the hand should be turned back at the elbow. End: repulsive movements from the water plane are performed using the hand and forearm. This stage ends in the pelvic region;

Exit of the upper limb from the water plane. The movement should coincide with the lean to the other side. An elbow protrudes above the water, then a hand emerging from the water in the thigh area behind the pelvis;

Movement with one hand over the water surface or carry should be made at the same time with the stroke of the other upper limb. Bent at the elbow, the relaxed arm sweeps quickly and the movement accelerates before entering the depths of the water. The palm is directed back and slightly upward at the start of the sweep;

The entry of the hand into the water plane and the influx. The hand is directed forward and downward. The horizontal speed must be higher than the vertical speed. The entry into the water plane is made where there is an imaginary point between the parallel through the shoulder joint and the longitudinal axis of the body. Entry into the water is made with a brush, an acute angle is observed. The arm at this moment is still bent and straightens only with an influx. First the hand enters, then the forearm and shoulder. Next, the relaxed arm should be extended forward. Expand the hand vertically to the direction of movement at the end of the influx, bend the arm in the region of the elbow joint.

To ensure continuous traction, it is necessary to perform stroke with your hands at the same time If one hand starts pushing away, then the other should be in the capture stage and rest on the water surface.
