Volleyball cushion technique is one of the basic techniques of volleyball. Players transfer volleyball to the opponent's playing field by patting the ball with both hands. The specific skills are as follows.
First, prepare the posture.
1. point
It can be divided into micro-squatting posture, semi-squatting posture and low squatting posture. When you put the ball on the wall, you should take a semi-squat posture. The semi-squat posture requires that the feet are open, the knees are bent, the upper body leans forward, the center of gravity is in front, the vertical line of the knees should be in front of the toes, and the arms should be relaxed and naturally bent in front of the abdomen.
2. Easy to make mistakes
(1) The posture is too high or too low.
(2) only bend over and not bend your knees.
3. Corrective methods and practical measures
Practice method 1. Repeat unarmed exercises according to the main points of correct movements.
In teaching, students are divided into groups of 3-5 people. First, let the students look at the pictures and discuss the correct action essentials. Then, the students do imitation exercises against the pictures. Teachers should correct the wrong behavior in the process of touring guidance.
Exercise 2. Students are doing unarmed exercises on the wall.
In teaching, I draw a line with a certain height on the wall in advance (according to the height of the students, draw lines with different heights), let the students squat on the knee joint of the wall and lean forward slightly, and ask each student's knee joint not to be higher than the line on the wall in front of them. After repeated practice, students can establish correct posture stereotypes and lay the foundation for holding the ball.
Exercise 3. Touch the ground with both hands.
Move two steps to the left with both hands holding the ball, squat half, touch the ground with both hands holding the ball, and then do the same in the opposite direction. After the students understand the action, the teacher can let the students listen to the password or watch the teacher's instructions to do the quick movement and placement exercises before, after, left and right.
Second, the ball touches the arm to hit the ball.
1. point
Hit the ball with a plane formed by the inside of the radius of both forearms about 10 cm above the wrist joint of the forearm; The lower back of the ball.
2. Easy to make mistakes
(1) When the ball hits the wrist, the cushion ball is unstable due to the small contact surface.
(2) If the ball hits the lower right part (the hitting part of the upward self-propelled ball), the result is that the ball goes straight up and can't touch the wall, nor can it touch the higher wall, so the ball can't bounce back normally.
(3) hitting the ball with one arm.
3. Corrective methods and practical measures
Practice 1, the practice of making up the ball
In practice, three people throw a ball, one holds the ball in front of the abdomen, one does batting practice, and the other stands by to observe whether the batter's hand shape and batting position are correct, and reminds and corrects it at any time. At the same time, it is emphasized that the ball holder should not unconsciously raise the ball in his hand to cause the batter's wrong action. After several exercises, the roles of the three players were reversed. After repeated practice, students can understand where the ball should be hit.
Exercise 2. Practice by yourself
On the basis of exercise 1, each person takes a ball, stands in front of the wall, holds the ball between the forearm and the wall, and uses the lower limb pedaling action to understand the position relationship between the ball and the arm and the correct hitting position. In this exercise, it may be difficult for students to control the ball at first. At this time, teachers should use the "advantage amplification method" to encourage and praise students who have made little progress and establish confidence in practice. At the same time, teachers should strengthen tour guidance to help students establish correct action stereotypes more quickly.
Volleyball technique
The basic skills are divided into six major items, namely, preparing posture and moving, passing, padding, serving, spiking and blocking. Volleyball techniques include passing, padding, serving, spiking, wiping, blocking, tactics and movements.
pass the ball
Passing the ball is the action of hitting the ball through the strength between the wrists with the help of kicking, jumping and stretching your arms above your chest.
The main function of passing the ball is to pass it to the rest of the players for attack or direct attack. Whether a team's offensive ability can be brought into full play depends largely on the passing level of the team. In order to compete for online advantage and make offensive tactics fast and changeable, the role of setter is more core.
Cushion ball
It is a technical action to hit the ball by kicking and lifting the arm with the rebound force of the forearms of both hands and the incoming ball. Cushion ball is mostly used to receive service, spike and block tennis in the game, which is an important technology to change passive into active and win with more points and less points.
service
A technical action in which the player throws the ball himself and hits the ball from the net into the opponent's court with one hand. Serving is the beginning of competition and attack, and it is the only technical action in volleyball that is not restricted by others.
Serving vigorously can not only help you score easily, but also reduce the opponent's strength and disrupt the opponent's layout.
spike
The technical action of jumping in the air, swinging an arc with one arm, hitting the ball across one's own court with one hand and shooting it into the other's court from the net in two marker posts. Spike is the most active and effective weapon in the game, so it is the main means to score points and gain strength.
Wipe the ball
The hitting method that the setter or attacker quickly wipes the ball off the net with one hand to make it enter the opponent's court quickly and unexpectedly is a remedial play to make up for the probe error caused by the Qualcomm pad, but it is sometimes deliberately used to form two balls.
block
In front of the net, the player uses any part of his body above the waist, mainly his arms and palms, to stop the opponent from hitting the ball over the net. Blocking is the first line of defense and an important part of counterattack. Blocking can block the opponent's powerful smash, reduce the pressure of the back row defense, and create conditions for our organization to counterattack. Blocking is mainly through psychological pressure to force the opponent's attacker to make mistakes.
Sea volleyball
It can slow down the speed of the ball and even directly block the opponent's spike, which is one of the important means to score points and gain strength in the game.
Volleyball catching technique
1, catch the ball head-on
(1) Prepare posture
Face the incoming ball, feet are wider than shoulders, one foot is in front, two heels are raised, forefoot touches the ground, knees are slightly flexed and retracted, center of gravity is slightly tilted forward, arms are naturally bent, and placed in front of abdomen.
(2) Hand type, hitting point and touching position
When the ball is close to the front of the abdomen, the hands are folded, the palms are close together, the palms are locked, the two thumbs are parallel to the front, the arms are straight, the wrists are pressed down, and the cheeks formed by forearm rotation are close to the lower part of the wrist hitting the ball. The hitting point is at the left and right distance of the arm in front of the abdomen, which is convenient to control the strength and adjust the arm angle according to the direction of catching the ball.
(3) Hit the ball hard
Put your arms forward and insert them under the ball, relying on your arms to increase the strength of the ball, and at the same time, with the action of your waist, your body's center of gravity moves forward and upward. When hitting the ball, the two arms should form a plane, and the body and the two arms should naturally accompany the ball and control the landing point and direction of the ball.
When catching the ball, you should also control the movement of your arm according to the strength of the incoming ball, and adopt the above action when catching the ball lightly. When receiving a medium-intensity incoming ball, because the incoming ball has a certain speed, the arm movement should be small and the speed should be slow, mainly relying on the rebound force generated by the incoming ball itself to pick up the ball.
When catching a heavy ball, you should take the action of abdomen and chest, and bend your elbow with the incoming ball to buffer the power of the incoming ball and control the distance of catching the ball. When the ball is a little far away from the body and the hitting point is low, the arm should bend its elbow and wrist, and the ball will be connected to the tiger's mouth at the wrist during the buffering process.
2. Hands on the side to catch the ball
The action of catching the ball with your arms on both sides of your body is called side catching. Use when the incoming ball is fast, away from the body, and it is too late to move the aiming ball. Body-side catching can expand the defensive range, but it is difficult to control the direction of catching the ball. So when you have time to move, you'd better grab it with your head.
When the ball flies from the right side, the inside of the forefoot of the left foot touches the ground and the right foot takes a step to the right. The right knee bends and the center of gravity immediately moves to the right foot. The two arms are clamped and extended to the right, and the left shoulder is slightly inclined downward. With the rotation of the left waist and the lifting of the right door, the hitting surfaces of the two arms intercepted the flight path of the ball and touched the lower part of the ball.
Don't stretch your arm with the ball when touching the edge, which will cause the ball to fly sideways after touching the arm. We should let the two arms reach out to the side to intercept the ball first, and also pay attention to the fact that the two arms can't bend to keep the arm hitting the ball and avoid the effect of catching the ball being affected by the arm movements.
Step 3 get the ball back
Back-to-back is to catch the ball from the front of the body to the back. Used when the ball flies too far to adjust the pass positively, or when the third passive shot crosses the net.
To judge the flying direction of the ball, we must first quickly move to the landing point of the ball, turn our backs to the direction of the ball, and clamp and straighten our arms and insert them under the ball. When hitting the ball, push your head and chest to the ground, expand your abdomen and lean back, and swing your straight arm back and forth. When you catch the low ball and return it, you can also bend your elbow and lift your wrist, and take the ball back and up at the tiger's mouth.
Step 4 to catch the ball
The action of catching the ball by an athlete taking a step forward or sideways is called stride catching. Step-by-step catching is mainly used for serving and defending.
Front span catcher
When the incoming ball is low and far away, look at the landing point of the incoming ball, take a big step forward, kneel down, focus on the stepped leg, the upper body leans forward, the hips droop, the arms stretch forward and insert under the ball, and the forearm is connected with the lower back of the ball.
Side span lock
When the ball comes to the right, take a big step to the right with your right foot, bend your knees and brake, and shift your center of gravity to step out of your leg. The upper body leans forward, the hips droop, the arm is inserted under the ball, and the forearm is used to catch the lower part of the ball.
