  1. Adduction of the upper arm to maximize forward propulsion

    內收上臂以產生最大的向前推進力。
  2. The arm recovery accelerates and the hand drives forward into the water while the opposite hand pushes back achieving maximum hand velocity and propulsion

    當對側手向後推水，達到最快的劃水速度和最大推進力的時候，移臂開始加速，驅動手掌前伸入水。
  3. Body roll occurs largely to position sets of muscles to move joints to produce longitudinal forward propulsion and coupled with the arm pull produces a more direct propulsive force off the hand / forearm - propelling surface

    身體的滾動幅度大會使肌肉群一起運動產生縱向的推進力而且是兩倍于手臂劃水直接產生的推進力。
  4. An elevation of the shoulder, medial rotation of the upper arm, and late flexion at the elbow as the body rotates to accommodate an " elbows - up " position and to reposition the forearm / hand drag surface to where forward propulsion can be created

    提肩，上臂轉一半，然後屈肘使身體轉動達到一個高肘位置接著重新入水並使前臂和手掌通過抱水能夠產生向前的推進力。
