INWARD DIVE TUCK

DIVE 401C

 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 knees in front of the body line toward the chest and bring the arms forward and downward to continue the forward rotation.

6.  Bring arms forward and downward, then in toward body, bending the elbows and preparing the hands to grab the legs for the tuck. 

7.  Establish the tuck position with knees making contact with shoulders, heels making contact with buttocks, and one hand clasping each shin between the knee and the ankle. 

8.  Maintain the tuck position until the hips are the highest point of the body relative to the water.

9.  Still sighting the water, prepare for the kick-out.

10.  Kickout Styles

a.  Straight kick-out – extend the legs, knees first, forcefully while squeezing midsection muscles tightly, so that the entire body, minus the arms, comes into a straight line.

b.  Pike out  -- extend the legs from the knees, with the toes pointing at an angle that maintains control of the rotation (too far in front of the hips causes the rotation to slow too much and the dive to get “stuck;” too far up and behind causes the dive to over-rotate uncontrollably. 

11.  Arm Movements from the Tuck to the Entry

a.  Midline (typically combined with a straight kick)

1.  During the kicking action, move the arms to a bent position, close to the torso, with the hands grabbing for entry.

2.  Extending the arms overhead while adjusting the hands so the flat palm is parallel to the water.

 b.  Lateral (typically combined with a pike-out)

1.  During the kicking action, extend the arms outward from the elbows to establish a set position.

2.  Keeping the shoulders relaxed and torso hollow, move the arms laterally from “set” position until they come overhead. 

3.  Flip the wrists such that palms face the water and maneuver hands into grabbed entry position such that the flat palm is parallel to the water.

12.  The Kickout and Arm Actions should happen in quick succession, with smooth transitions from one position to the next.

13.  Align the body for a drop to the water that results in an entry line just short of vertical.
