　　Old drought the breaststroke of 4 bid farewell

　　Part company press wrist, dual anchorage track, tall ancon holds water in the arms, turn over the shoulder since the palm.

Stalk neck gives water, anguine waist pulls coxa, close hang down double genu, two sufficient evaginate.

Enter water concealed head, approach arm hides a shoulder, inside ankle backward, pedal places underspin.

Before low hind tall, slippery Sha Shen is exhibited, stretch tight the leg receives an abdomen, float rises surface.

Behavioral structure and technology want a place

(1) swim member in glide pose, the body approachs a level. The head is made an appointment with 80% heavy Yu Shuizhong, face slightly forward, double arm extend, the centre of the palm to inclined outside side.

(2) the movement that catch water makes an appointment with 7~9 very little place to begin in underwater, both hands makes lateral row, beginning expiratory action at this moment.

(3) double arm did not have apparent inflectional, continual delimits outward side, expiratory continue to increase. (4) when swim member the head begins slightly up, ancon joint begins inflectional, the upper arm begins to rotate. (5) arrive at the biggest width when double arm, ancon bends about 110 degrees, at this moment tall ancon pose is apparent. (6) the head continues to carry, show water when mouth ministry, expiratory finally finish. Both hands begins to 內 , in order to finish final propulsion movement. (7) prepare when double arm backward, inspiratory begin, elbow does not pull down rib, knee joint begins inflectional, the movement that wind a leg begins. (8) mouth ministry is closed, inspiratory finish, double sufficient by 帶 to hip, ancon joint continues extend, double arm continues to move ahead. (9) proceed of the movement that wind a leg. (10) cervical and inflectional, the head continues to tilt downward. Double sufficient back is bent, double leg begins backward, postpone water action, movement of double arm turn around and stretch out one's hand. (11) double sufficient push begin backward and approach. Swim member shut gas at this moment, till another delimit brachial movements begins. (12) double arm is complete extend, both hands a bit under humeral arm level, water of double leg pedal is adjacent finish. When swim member water of the pedal that finish, make the body is become centrally all the time line. His 將 holds the time of short 暫 of this glide pose, feel when him speed 減 is slow next, another delimit the arm begins circularly.
