REVERSE SOMERSAULT TUCK

DIVE 302C

 SPRINGBOARD BIO-MECHANICS DISCUSSION

 

   

1.  During the pressing action, angle the body very slightly 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 behind the ears. 

3.  Lower torso remains hollow, while chest and shoulders open a bit, 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, forward, while creating enough rotation for the somersault to be done.  Hips will move upward and forward as the legs finish their extension.

4.  After legs have been fully extended and the feet have left the board, simultaneously round the upper body forward and bring the knees up toward the chest.  Arms either drop in front of the body line, bent at the elbows, or make a small, bent-elbow circling movement, in anticipation of grabbing the tuck.

5.  As the knees come up into the chest, rotate the hips forward/upward and pull the buttocks underneath the torso. 

6.  As the hands grab the legs for the tuck. Relax most of your muscles, except the ones needed to squeeze your tuck and establish the smallest possible position.

7.  Maintain the tuck position until the hips/low back are slightly shy of having completed a full revolution.

8.  Sighting the water, prepare for the kick-out.

9.  Kickout Styles

a.  Straight kick-out – extend the legs against the direction of rotation, knees first, forcefully while squeezing midsection muscles tightly, so that the entire body, comes into a straight line with the arms resting flat on the front or side of the body/legs.  Eyes should sight the toes or water.

b.  Pike out  -- extend the legs from the knees, with the toes pointing toward the water, slightly in back of the bodyline, at an angle that maintains control of the rotation.  Too low a kick causes a continuation of rotation that cannot be controlled and too high a kick 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.

10.  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 water.   Finish pressing the legs down so the body is straight, with arms at sides, and the entry line is slightly short of vertical.
