Volleyball is one of the ball games in which the court is rectangular with high nets at intervals, and players hit the ball over the net with their hands. The ball used in volleyball is made of sheepskin or artificial leather, and the rubber is made of gall, and the size is similar to that of a football. The sport originated in the United States in 1895 by a sports worker named William G. Morgan in Holyyoke, Massachusetts, USA.
In the early days, volleyball was called a mintonette. In 1896, according to the characteristics of the game, Professor Holstead proposed to change it to volleyball, which is the modern international name volleyball. The official sphere at that time had a circumference of 25 27 inches (about centimeters) and a weight of 9 12 ounces (about 255 346 grams).
The materials and manufacturing processes of modern international balls have changed greatly, but the specifications of the balls are still the same as before.

Summary. Hello, I'm glad to give you an answer, volleyball consists of two teams of six members each, and later added liberos. The aim of volleyball is to score a goal by making the ball slightly higher than the outstretched hands in front of the net, so that the ball falls into the opponent's half of the court.
Each team's players have their own fixed positions, three players in front of the net and three players close to the baseline. Each side must not hit the ball over the net more than three times, and an attacker and a teammate will intercept the ball in front of the net to prevent the ball from falling into their own half and score directly through the interception.

Volleyball is played as follows:
1. Serving is the first step in playing volleyball, and it is also the first and most important step in a volleyball competition. The basic skill of serving is to throw the ball upwards with the left hand, and after the ball falls, wave the arm at the right height to hit the ball over the net cushion ball. The basic action of cushioning the ball is to loosen the right hand and clench the fist, put it on the left hand, and the two hands are naturally closed; The arms are naturally straightened and clamped, maintaining a certain level of tension, and the whole arm is raised at about 90° with the body.
2. Rub the ball, when the ball comes to you, the first thing is not to send it out all at once, but to use your arms to form a platform to stop the ball, merge the two arms, and not go too much between the arms to prevent the ball from leaking. Smash the ball, on the basis of the previous step, a pass will come out, and when the second pass is about to wear out, the smasher will look at the direction of the second pass to move, and the last blow will hit.
3. Blocking the net, after the opponent's smasher jumps up, the person who blocks the rubber net jumps, reaches out, pushes the wrist, and closes his hand at his best effective height.
Precautions for volleyball
First, the warm-up exercise should be done sufficiently.
The content and amount of warm-up exercises should be determined according to the nature of the activity to be practiced and the player's own situation. For example, before jumping exercises such as smashing the ball and blocking the net, you should do more preparatory activities for the lower limbs; Before serving and smashing the ball, you should do more preparatory activities for the shoulder joint. The interval between the end of the warm-up exercise and the formal exercise should be 1-4 minutes, and the body is generally warm and slightly sweating.
Second, it is the focus on protecting the joints.
Wear knee pads, ankle pads, wrist pads, elbow pads, finger gloves, etc. when exercising to protect joints that are prone to injury. In addition, strengthening the comprehensive training of the body and improving the body's adaptability to sports is a positive means to prevent sports injuries, especially to strengthen the training of relatively weak parts such as knee joints, shoulder joints, and wrist joints. If you are accidentally injured during sports, you should stop the game immediately and deal with it in time; If you have a serious wound, seek medical attention immediately.
Third, pay attention to the diet after exercise.
Sweating during exercise leads to water loss, so you should replenish water at the right time, but not too much. Because there is less blood in the gastrointestinal tract after exercise, the function is poor, and the absorption of water is weak, so you can drink some light salt water slowly after exercise. After exercise, in addition to the increase in water loss, the body also loses many minerals along with sweat, mainly potassium and sodium.
Exercisers can increase their intake of these minerals by eating more fruits and vegetables, such as bananas, oranges, mushrooms, cauliflower, peanuts, etc.

The first step in playing volleyball is to learn to cushion the ball, which is easy to say and difficult to say. First of all, the posture should be correct, the hands should be naturally bent, and the feet should be forward and backward, and when the ball comes, the arms should also maintain a certain tension, and it is best to keep the arms at a right angle to your body, preferably unchanged. When the ball comes, use the first third of your forearm to touch the ball, and rely on the inertia of your body to touch the ball, so as to cushion the ball back, this action is to be practiced repeatedly.
The second thing to learn is to serve and pass, the best way to serve is to hit with your own palm, and jump slightly, there is to control the position of the ball, can not be too close and can not send out bounds, this is easy to do with a few more exercises, passing is mainly to pass with both hands, but pay attention to not to grasp the ball with both hands, can not let the ball stay in the hand, this process should be as natural as possible.
Let's talk about smashing the ball, smashing the ball is generally tactical, after the first pass pads the ball, the second pass needs to pass the ball to a suitable position of the first sakura, and you must watch the action of the second setter when you smash the ball, so as to ensure that you are in the right position, and the main thing you need to do is the angle and power, so that you can score at the fastest time. The last technical action is to block the net, which needs to be envied by people who are good at high and jumping, and it is best to be about 20 cm away from the net, and their hands should be about 5 cm away from the net.
The basic techniques of volleyball are: preparing posture and movement, serving, cushioning, passing, smashing, and blocking. >>>More
