Volleyball technical characteristics of volleyball technology

It is the technology to pass the ball to the buckler for attacking after receiving a pass or defense. 80's put forward higher requirements for the development of passing technology, not only to hold up the ball steadily and accurately, but also to be able to confuse the other side, avoid pulling the net, and make up fast and changeable attacking tactics to achieve the purpose of assisting the attacker. In modern volleyball games, the second passer often plays the role of bridge and core from defense to offense, which requires special skills. China has always attached great importance to the special training of the second passer, especially since 1976, the strongest teams have generally started to cultivate the second passer who is taller in stature, calm in mind, strong in tactical sense, capable of blocking and dunking, and skillful in passing technology. Shen Fulin, the excellent second passer of national men's volleyball team, was good at hidden passing, cooperated with his companions very closely, and was able to choose breakthroughs flexibly and make up all kinds of fast-change tactics. Sun Jinfang, the captain of the national women's volleyball team, can pass the ball according to the characteristics of the dunker, with strong cover of jumping up to pass the ball, and the left hand dunking ball has strong attacking power, and she is a good dunker who can pass the ball. In addition, there are various adjusting passes, jumping up shaking passes, passes to the side and various fake passes, etc., all of which are the passing skills that make the Chinese volleyball tactics more flexible and changeable (Figure 3).

It is the last blow of tactical cooperation, the most active and effective technology in the offense, and an important means of scoring and gaining the right to serve, which is one of the elements to measure the strength of a team's offense. The higher the level of a team's deduction technology, the more favorable conditions it can provide for the improvement of blocking and deduction technology. The attacking power of the ball is mainly manifested in the height, speed, power, change and suddenness. According to the test, an excellent athlete of a heavy buckle, the ball speed can reach about 28 meters per second. Powerful dunking is often in the change of the ball path and with the combination of light hitting soft hanging to break through the net. An excellent dunker should be able to attack the ball both strongly and quickly, and also have his own characteristics. Strong attacking dink is the foundation of dinking, which generally includes near-net high ball strong attack (flat net dink) and adjusting strong attack (diagonal net dink). Fast ball and quick attack is an important feature of the development of volleyball in the world nowadays. Whether it is the Olympic Volleyball Tournament, the World Cup Volleyball Tournament or the World Volleyball Championships, almost all of the strongest teams are increasingly using fastball. Some teams with mainly high hitting have also absorbed the fast hitting style. Chinese volleyball has traditionally been known for its quickness. In the sports competitions of the 2nd World Student Congress in 1950 (China's first participation in 6-a-side volleyball) and the 1st World Volleyball Championships in Paris in 1956, the Chinese team used the traditional "fast ball". Since then, countries gradually adopted this style of play, and in the 1965-1966 China-Japan Men's Volleyball Tournament and the World Men's Volleyball Championship, the Chinese National Team and the Beijing Team creatively used the No.4 position to play a flat pull and fast ball. Later, the Japanese team developed the current short and flat fastball on the basis of this. In order to break through the net, the Chinese athletes have developed the punch dunk (front dunk and back dunk) on the basis of vigorously improving the bouncing power, that is to say, after jumping and in the process of leaping, they choose the suitable breakthrough to hit the ball (Fig. 4 and Fig. 5), and the pull 3 and pull 4 dunk (developed from the short and flat fastball, which is the point of hitting the ball from the right side of the No. 3 or No. 4 player is misplaced and pulls the ball from the left side for the dunking), and other new techniques such as the difference in time, the difference in space and the difference in position. The new technology. Chinese men's volleyball team's excellent dunker Wang Jiawei's punch dunk, in many major games, the hitting rate is often as high as 70% or more, in 1979 and 1981 was twice selected as the best men's volleyball player in Asia. Currently, in the domestic and international strong team games, the men's team strong attack and fast attack about half each. The women's team has more strong attacks than fast attacks. The Chinese team is known for its fast attack, and is gradually improving its strong attack, so that the strong attack and fast attack can be combined organically. Cultivation of excellent ball player, but also to pay attention to its personal strengths, but also to make it master the strong attack and fast attack technology. Such as the national women's volleyball team Lang Ping, both excellent heavy dunking player, fast attack technology is also very skilled.

The main points of dunking After the dunking jump, the first chest and head up to show the abdomen, arm elbow bend to the back up, the body into a reverse bow shape. The use of the abdomen, turn the body to close the chest movement force, drive the forearm upward fling to hit the ball, swinging to have lifted the shoulder and elbow action, the forearm into an arc of fast forward and upward flinging, in the shoulder above the highest point to hit the ball. When the hand touches the ball, use the whole palm to cover the top of the back of the ball, so that the ball is upwardly rotating and falls into the opponent's field rapidly. Positive passing 1: Preparation posture: see the ball, quickly move down to the ball's landing point, to the incoming ball, feet left and right open stand, about the same as the shoulder width, left foot slightly in front of the heel of the right foot slightly lifted, two knees slightly flexed, slightly leaning forward, two arms bent in front of the chest, two elbows naturally drooped, both hands into the hand shape of a pass, eyes watching the direction of the incoming ball. 2: Striking point: striking point in the forehead above the ball at about the distance of the ball. 3: Passing Hand Shape: When the hand touches the ball, the wrist is slightly backward, the wrist is slightly backward, so that the ball falls rapidly into the opponent's field. When the hands touch the ball, the wrists are slightly tilted back, the hands are naturally open, and the fingers are slightly bent into a hemisphere. The distance between the two thumbs should not be too big to prevent the ball from escaping.4: Strike force: when the ball comes, both hands slightly open to meet the ball, with the inner side of the thumb, the index finger, all the middle finger, the two or three knuckles of the middle finger to touch the lower part of the back of the ball, the ring finger and the little finger to touch the ends of the ball. The ring finger and little finger touch both ends of the ball. The ball is passed with the elasticity of the fingers and the coordinated strength of the arms and the body. After judging the incoming ball, move quickly under the ball, raise both hands, and when the hands touch the ball, tilt the wrists back appropriately, palm up, and hit the lower part of the ball above the forehead, and when passing the ball, pass the ball to the upper part of the body with the force of the stirrups, the spreading of the abdomen, the lifting of the arms, the turning of the wrists backward, and the elasticity of the fingers to pass the ball out to the upper part of the back. The best way to pass the ball is to jump vertically upward, and to master the time of jumping, jumping too early or too late will affect the quality of the pass. According to the height of a pass, jump in time, both hands in front of the face, when the body rises to the highest point, relying on the arm extension and finger and wrist popping power to pass the ball. Because there is no support point in the air, can not use the stomping force, only by the power of arm extension to pass the ball, therefore, must be in the body before the fall of the pass out, in order to control the power of the pass. Generally, the front pass is the simplest and most commonly used tactic in the second pass. The action of the pass is basically the same as the frontal pass, only the body before the pass should not be facing the incoming ball, nor facing the direction of the pass, but to meet the ball while turning around, put the striking point on the side of the direction of the pass, and the body with the passing action while passing to the direction of the pass. Adjustment of the second pass will be a pass is not in place, far from the net of the ball to the deduction of the player offense, this kind of pass is called adjustment of the second pass. Adjustment of the two passes and the front of the passing action is the same, when passing, pay attention to the selection of the direction of the pass, the direction of the pass and the smaller the angle of the net is more conducive to deduction, try to avoid vertical to the front of the net to pass the ball, at the same time, the height of the pass should be a little high, do not be too open, which will be conducive to deduction players to observe and step on the deduction of the ball. Back to the second pass back to the second pass to be able to use the full length of the net, increase the point of attack, has a great concealment, suddenness. Before passing the ball, you should first move to insert the ball under the back to the direction of the pass, to make clear the position of the body and the distance from the marking pole, when passing the ball, you should utilize the backward and upward body exhibition, arm lifting, elbow stretching action to pass the ball out. Passing the fastball passes the ball arc low, fast rhythm. Passing the fastball mainly relies on the finger and wrist flick action and appropriate arm extension to control the passing power. To pass a good fastball, the second player must take the initiative to cooperate with the ball player, according to the arc of the pass, speed and the ball player's running speed, jumping time, the height of the batting point and swinging arm speed, etc., to determine the speed, height, distance and time of the ball, the ball initiative to the hands of the ball player. Passing short and fast ball pass out of the ball speed, arc flat, landing point from the second passer 2 to 3 meters. When passing the ball, the striking point should be kept in front of the face or forehead, leaning forward, making full use of the elbow and wrist action, passing a fast flat arc ball. The ball passed out by the flat pull-off pass is fast and flat, and the landing point is 6 to 7 meters away from the second passer. Flat open pass and short and fast pass action is basically the same, but to make full use of stirrups, arm extension, wrist pressure and accompanying action to pass the ball. If the incoming ball is low, bend your knees slightly and lower your center of gravity to keep the point of impact in front of your face. If the incoming ball is high, a jump pass can be used. When passing the ball, utilize the elbow extension and actively increase the power of finger and wrist flexion to flatten the passing route. This is a prelude to the basic techniques. Preparation posture is good or bad, directly affects the foot movement in time and accuracy; and foot movement is good or bad, and directly affects the quality of the completed technical action. According to statistics, in the defense because of the slow movement of the ball to the ground accounted for about 50% of the total number of defense errors.
