Techniques for pushing the shot put in place:
1. Grip and ball-holding techniques
(Take right-handed throwing as an example) The five fingers of the hand holding the ball are naturally separated. Place the ball at the base of your index finger, middle finger, and ring finger, with your thumb and little finger attached to both sides of the ball to keep the ball stable. After holding the ball, place the ball above the inner end of the clavicle, close to the neck, with the palm facing forward, the right elbow slightly raised, the right upper arm and the trunk forming an angle of approximately 90°, and the torso and head kept upright.
2. Preparatory stance technique
Draw a straight line about 1 meter long, and draw a line about 30 cm long on the left side of the front end of the straight line and the right side of the back end. Oblique lines, the angles between the two oblique lines and the straight line are less than 45° and 90° respectively. The left and right feet step on the diagonal lines at the front and rear ends respectively, in the same direction as the diagonal lines. The toes of the left toe and the heel of the right heel are approximately in line.
Then lower the center of gravity and bend the knees into a half-squat. Then move the center of gravity to the right leg. Turn the upper body about 90° to the right, bend forward slightly, and lower the head slightly to hold the chest. Bend your left arm at the elbow and lift it slightly upward. The left knee should be abducted appropriately, the right knee should be slightly buckled inward, and the forefoot of the right foot should be buckled inward on the ground.
Relax your upper body, right arm and left forearm appropriately, and look at a position about 0.5 meters directly to the right of your right foot. Most of the body weight rests on the right leg. It is appropriate to move the body's center of gravity to the right until you can gently lift your left foot, and relax your back. The correct stance should basically be four lines: first, the left shoulder, right knee, and right toe are on a vertical line; second, the tip of the right hip and the heel of the right foot are on a vertical line; third, the right foot is on the throwing line. Near the center of the circle, the left foot is at an angle of 30° to 45° to the left of the throwing direction, and the right heel and left toe are in a straight line; fourth, the left side of the body forms a diagonal line.
3. The correct sequence of final force
In teaching, there are many objections to the understanding of the essentials of the shot put push in place. Some people suggest that kicking, turning, sending, pushing, Push, push; some people propose kicking, turning, pushing, pushing, and pushing; others propose raising, kicking, turning, pushing, pushing, and pushing; although the above formulations have their own emphasis, they are obviously not comprehensive enough. After long-term teaching practice, I think the following formulation is more appropriate. The correct final sequence of force can be summarized as the eight-character essentials: kicking, turning, sending, lifting, straightening, supporting, pushing, and pushing. It is a bottom-up force sequence. "Kick, turn, send" is the lower limb movement of turning the right foot and leg and pushing the right hip in the throwing direction. "Lift, straighten" refers to the action of lifting the upper body and straightening the chest.
"Support" refers to the strong support on the left side to maintain a high center of gravity. "Push, dial" refers to pushing the ball quickly and dialing the finger. When you are ready to stand, you should immediately turn your right leg, push your right hip in the throwing direction, lift your upper body quickly, and under the traction of your left arm, quickly turn your body and raise your chest, with strong support from the left side , relying on the counter-vibration energy of the side arch of the body, the power is transmitted from the lower limbs, through the hips, waist, chest, shoulders, upper arms, forearms, wrists, and finally to the fingers to throw the shot put forcefully along an angle of 38° to 42°.
