REVERSE DIVE STRAIGHT

DIVE 301A

 SPRINGBOARD BIO-MECHANICS DISCUSSION

 

   

1.  During the pressing action, angle the body a bit forward, with the chest slightly in front of the hips/toes. Keep eyes focused on the anticipated entry point or other desired spot.           

2.  As arms reach overhead, they are shoulder-width apart with palms facing either inward or forward.  The arms extend slightly behind the ears. 

3.  Lower torso remains hollow, while chest and shoulders open slightly, and, as legs extend, with knees straight, balls of feet push downward and backward into the board, creating an equal and opposite reaction carrying the body upward and, combined with the arms/upper body positioning, backward, while creating enough rotation for the half somersault to be done.

4.  As the legs complete their extension, drop the arms smoothly into the set position, before the feet leave the board, thereby minimizing excessive movement during the dive.

5.  During/after the setting action, the amount of opening of the chest/shoulder area may be adjusted to control the rate of rotation (opening chest more causes arch and slows the rotation, while closing the chest more speeds up the rate of rotation.  The muscular actions of “pulling the chest” or dropping the arms below the set position can speed up the rotation).  Such adjustments should be very small and not affect the smooth flight of the dive.

6.  After the set, the head smoothly tilts back ever so slightly, allowing the eyes to sight the water in anticipation of the entry. 

7.  Once the water has been sighted, or the trajectory of the dive has been calculated by the body’s kinesthetic senses, the lower body presses the legs in the opposite direction of rotation while the arms close with a lateral arm movement and the rest of the mechanics for a back entry are employed.
