INWARD DIVE , ONE-HALF TWIST, PIKE

DIVE 5411B

 SPRINGBOARD BIO-MECHANICS DISCUSSION

   

1.  During the pressing action, angle the body very slightly forward. Keep eyes focused on the back end of the board.        

2.  As arms reach overhead, they are shoulder-width apart with palms facing forward.  

3.  Torso hollows, and as legs extend, with knees straight, balls of feet push forward and downward into the board, creating an equal and opposite reaction carrying the body backward and upward away for the board. 

4.  Shoulders round upward and slightly forward, thereby creating enough angular momentum, when combined with the leg extension and the slight lean forward, to be directed into a half somersault.

5.  With the torso and arms rounded slightly forward, the hips have room to ascend.  As the hips ascend (resulting from the combination of rounding upper body forward, relaxing the abdominal and hip area, and allowing the board to push the lower body into the air), simultaneously draw the feet slightly front of the body line toward the chest and bring the arms forward and downward to continue the forward rotation.

5.  Bring arms forward and downward, shoulder width or wider apart, then in toward the toes.

6.  Establish the pike position with chest and quadriceps approaching each other, head remaining between the armline and the legs, chin up to allow eyes to maintain sight of the anticipated entry point, and fingertips touching the tips of the toes.

7.  Maintain the pike position until the hips are the highest point of the body relative to the water.

8.  Still sighting the water, prepare for the come-out.

9.  Simultaneously, the arms and legs take action to both control the amount of somersault and initiate the twist.  The lead arm for the twisting action moves forward toward the entry point while the other arm pulls backward 180 degrees from the lead arm to initiate the twist and form the set position.  Some arm movement may be necessary during the dive to achieve the desired twist.  The hips and ankles on the same side as the “non-lead” arm turn in the opposite direction of the twist and the toes point back toward the board.

10.  Still sighting the water, open the chest more and tilt the head back, completing the twist and preparing the body for a back entry.

11. Once the entry point has been firmly established and the trajectory of the dive has been calculated by the body’s kinesthetic senses, the lower body presses the legs back toward the board while the arms close with a lateral arm movement and the rest of the mechanics discussed for a Back Entry are employed.
