BACK SOMERSAULT PIKE

DIVE 202B

 SPRINGBOARD BIO-MECHANICS DISCUSSION

 

   

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

2.  As straightened arms reach overhead, they are shoulder-width apart with palms facing either inward or forward.  The arms extend 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 slightly 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 somersault to be done.

4.  After legs have been fully extended and the feet have left the board, simultaneously round the upper body forward and begin to bring tops of the feet up toward the torso.  The arms either drop in front of the bodyline or make a circling motion behind the bodyline during the rounding of the upper body in anticipation of grabbing the pike. 

5.  Establish the pike position with body bending at the waist only, with each hand clasping a leg at or above the calf.  Squeeze the pike such that the chest makes contact with the legs.

6.  Maintain the pike position until the hips are just shy of having made a complete revolution.

7.  Sighting the water, prepare for the come-out.

8.  Kickout Style and Entry

a.  Extend the legs with the toes pointing toward the water, slightly in back of the bodyline, at an angle that maintains control of the rotation.  Too low an angle causes a continuation of rotation that cannot be controlled and too high an angle causes the angle of descent to be too short of vertical.  The arms may move into a set position to help control the body during the movement from pike to straight.

9.  Using the hips, abdominals, and buttocks, press the legs against the direction of rotation, then ease the torso upward and backward until a straight/slightly hollow body line has been established, with the arms resting flat on the front or side of the body/legs.  Eyes should sight the toes or the board.   Finish pressing the legs down so the body is straight, with arms at sides, and the entry line is slightly short of vertical.
