What are the precautions in volleyball?

Volleyball players are almost the best among all athletes, and people with poor balance ability can also improve their posture by playing volleyball. The following is an analysis of the matters needing attention in volleyball that I arranged for you, hoping to help you.

Matters needing attention in volleyball.

1, first run a few laps around the volleyball court, change the pattern, take a step, make a quick S-turn and change the direction.

2. After running, start to exercise your wrists, ankles, knees, ankles and hips, and do it several times.

3. Next, it's time to move your knees. Put your hands on your knees and turn around. Then relax the ankle joint and turn the left and right ankle joints respectively, and go back and forth several times.

4. Then relax your spine. First, move the cervical joint left and right, and twist the lumbar joint back and forth. Of course, leg press, expand your chest, do some jumps and try to relax all your joints.

In addition, wear knee pads, ankle pads, wrist pads, elbow pads and finger pads. Protect easily injured joints during exercise. Never do it? Vulnerable people? .

If you are accidentally injured in sports, you should stop the game immediately and deal with it in time. If there is serious injury, you should seek medical advice in time.

Volleyball cushion training

Ready 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.

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 will be that the ball will go straight up, and it can't touch the wall or the higher wall, so the ball can't bounce back normally.

(3) hitting the ball with one arm.

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. Should the teacher use it at this time? Superiority amplification method? Encourage and praise students who have made little progress and build confidence in practice. At the same time, teachers should strengthen tour guidance to help students establish correct action stereotypes more quickly.

Exercise 3. Repeat the unarmed exercise according to the correct action points.

In teaching, students are divided into 3? In groups of five, let the students look at the pictures and discuss the correct action points, then 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 4. 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.
