What technical moves are needed to throw a foul ball in football?

1. In-situ throw-in: a kind of throw-in technique. Stand where you are and throw the foul ball into the court. The key points of action are: facing the court, standing on the sidelines or stepping on the sidelines, holding the ball behind your head with both hands, leaning back as far as possible, with your knees slightly bent and your center of gravity resting on your feet, and throwing the ball into the court from the top of your head by using the concerted actions of landing your legs, belly in, swinging your arms and bending your wrists. Pay attention to the integrity of throwing the ball, which can be divided into two actions, uninterrupted. Both hands are equal in strength, and the ball should be thrown. Both feet can slide, but neither foot can leave the ground or enter the court with all feet.

2. Run-up throw-in: a throw-in technique. Throw a foul ball after the run-up The purpose is to apply the speed obtained from the run-up to the throwing of the ball, so that the ball can be thrown further. It is often used to throw a foul ball near the opponent's end line to directly threaten the opponent's door.

When throwing the ball out of bounds, the common fouls are: (1) failing to throw the ball out of bounds.

(2) Step on the court with one foot or both feet crossing the sideline.

(3) One or both feet leave the ground before throwing the ball.

(4) The ball is not thrown into the court from beginning to end.

(5) When throwing the ball, there is an obvious pause.

(6) When throwing the ball, the force exerted by both hands is obviously uneven. One hand holds the ball and the other hand throws it hard.

If the ball is not thrown into the court according to the prescribed method, the opposing team will throw the ball out of the court at the original out-of-bounds place.
