(a) blocking principle

1. When the ball is in the opponent's court, the front three players should be ready to block the ball at any time in front of the net.

2. The player in the middle of the front row is ready to intercept the ball attacking from the left or right direction with the player on the left or right at any time, and the other player is ready to block or save the ball.

(2) blocking technology

The blocker of the air volleyball should keep a close eye on the passing route of the opponent, judge the position of the ball in the air when the opponent hits the ball, and then move quickly (using parallel or cross move) to the corresponding position on the side of the net, and jump in place to block the ball. When taking off, the center of gravity is lowered to take off and the body balance is controlled to take off vertically. When BLOCKING, THE BODY SHOULD BE STRAIGHT UP AND DOWN. When the body falls at the end of blocking, the arm should not be bent, but the body should still be stretched when blocking. Only after keeping a certain distance from the net can the body be relaxed to avoid touching the net.

Block jumping time must be mastered, should be based on the opponent's two passes high and low, near and far, fast and spiking players jump time and action characteristics to decide.

When blocking the high ball, generally should jump later than the spiking player; ​when blocking the fastball, you can jump at the same time or in advance as the speaker.

At THE SAME TIME, the HANDS ARE CLOSE TO AND parallel TO the NET from the forehead and stretch out to the front and top of the net. The arms are straight, the forearms are close to the net, and the hands are as far as possible to reach over the other side to approach the ball. The hands are naturally open, and the distance between the two hands should not exceed one ball to prevent the ball from leaking between the two hands.

A blocker standing near the sideline turns his outside palm inward as he blocks the ball in order to prevent the opponent's enforcer from going out of bounds.

When two or three people block, they should cooperate closely. The main blocker should determine the center of blocking, and the cooperative player should choose the jumping point in time. ​collision and interference should be avoided when taking off.

After taking off, the arm in the air to maintain a proper distance, as far as possible to expand the arresting surface, but the distance between the hand and hand is not too large, so as not to cause leakage; ​players of different heights should strengthen the coordination of the take-off time. Generally speaking, the take-off time of tall players should be slightly later than that of short players. If you miss the ball, turn with the ball as you fall in the direction of the ball and prepare to make the catch and save. When you find that the opposing batting player steps over the 2M line, do not block the net, immediately back off and participate in the defense.

3. Solo blocker

Facing the net, watch the movement of the other side, two feet parallel open, about shoulder width, two knees slightly bent, hands naturally bent on the chest, according to the center line 20-30cm.

Move: After moving into position, take off from the side according to the opponent's jump time, and turn around in the air to face the net.

Jump in place: push off the ground with two feet, and swing up with two arms in a small arc to drive the body to take off vertically.

Moving jump: Pay attention to braking after moving so that your body is facing the net or turning in the air to face the net.

Air SHOT: TAKE OFF AT the same time, the hands from the forehead close TO and parallel to the net to the top, two arms straight, two shoulders as far as possible to lift, hands naturally open into a spoon shape, when the hand touches the ball, force to cover the ball in front of the top.

4. Collective block of air volleyball

Two or three people's cooperative block is called collective block. The purpose is to expand the block area, most of the two blocks.

When BLOCKING THE 4 OR 2 SPIKE, THE 2 OR 4 TAKE THE FIRST STEP, BLOCKING THE STRAIGHT OR MIDDLE SLASH, AND THE 3 AND COME TO BLOCK THE MIDDLE SLASH OR SMALL SLASH.

When BLOCKING THE 3 POSITION TO SPIKE THE BALL, the 3 position TAKES THE position first, the 2 or 4 position and one person comes over, and the two people share the main line of the column and the rotation line. The distance between the collective blockers and the distance between the two adjacent hands should be kept well, and the unified barrier should be formed as far as possible.

In the training of blocking, the emphasis is on the judgment of blocking, including the selection of position and jump time, the coordination of collective blocking, and the mastery of hand shape. ​Single block technique when the foundation, should first practice.
