FORWARD SOMERSAULT TUCK

DIVE 102C

 SPRINGBOARD BIO-MECHANICS DISCUSSION

 

 

1.  During the pressing action, angle the body very slightly forward. Keep eyes focused on the anticipated entry point.

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

3.  Torso hollows, and as legs extend, with knees straight and feet/toes pointed, shoulders round upward and slightly forward and the hands throw forward and downward, thereby creating enough angular momentum to be directed into a somersault.

4.  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 slightly in 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, then in toward body, bending the elbows and preparing the hands to grab the legs for the tuck.

6.  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.

7.  Maintain the tuck position until the hips have made a complete revolution.

8.  Extend the legs/body in one of the following manners to slow rotation and gain control for entry into the water.

9.  Kickout Styles and Entry

a.  Straight kick-out – extend the legs, knees first, forcefully while squeezing midsection muscles tightly, so that the entire body, minus the arms (which move down to the sides, comes into a straight line.  Angle of entry should be slightly short of vertical.

b.  Pike out  -- extend the legs from the knees, with the toes pointing at an angle that maintains control of the rotation (too far up causes the rotation to slow too much and the dive to get “stuck;” too far down causes the dive to over-rotate uncontrollably.  At the same time, pull the upper body slightly upward and backward, against the direction of rotation.  Finish pressing the legs down so the body is straight, with arms at sides, and the entry line is slightly short of vertical.
