INWARD DIVE , ONE-HALF TWIST, STRAIGHT

DIVE 5411A

 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.  Turn palms outward.

3.  Torso hollows, and as legs extend, 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.  heels lift to allow the body to rotate forward while maintaining straight position

5.  Simultaneously, the lead arm for the twisting action drops forward and downward while the other arm drops backward and downward 180 degrees from the lead arm to initiate the twist and form the set position.  Arms may reach the set position after the feet leave the board, as some arm movement may be necessary during the dive to achieve the desired twist.

6.  Push the lead arm forward and start to open up the chest, while pulling the opposite hip back toward the board.  With eyes fixed on the entry point, continue pushing the leading arm away from the torso and turn the palm upward. 

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

8. 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.
