If you have any errors, please point out. thank you very much.
I. Steps for the teaching technology
1. Demonstration through teachers to understand the action structure, master the technical principles, establish the basic concepts and images of action.
2, perform the right way to shoot exercises.
3, perform the conversion exercise of the front and backup.
4. Improve the grip technology through other techniques and hitting exercises.
5. Consolidate and skilled the grip technology through other technology exercises and games.
1, positive hand grip technology
Positive hand grip technology:
Everything is in the right side of the body, and in the top of the head, the backfinder hits the technology. When shooting the ball, holding the ball and hitting the ball and hitting the ball.
The main hand holding technology movement is:
a, when you hold, first hold the ball shot lever with your left hand, so that the face is vertical (photo)
B, open the right hand palm down, so that the tiger port is aligned with the small narrow side of the inside of the shot. (photo)
C, small finger, unknown finger and middle finger naturally and hold the handle, (just in the moment, the finger suddenly grips the handle.) Make the palm of the palm on the bottom of the tab. (photo).
D, the index finger is slightly separated, and the thumb is attached to the wide surface of the front, the index finger and the thumb finger are relatively buckled.
E, in order to relax the grip, the handle and the palm should not grip, there should be a gap. The size of the gap can be determined according to the palm size, but don't be too big, it is easy to make a shot too loose. When you hit the ball, the racket is easy to take off.
Second, anti-hand grip technology
1. All the anti-portrait of the anti-portrait of the body is used to take the technology with anti-hands holding technology. When shooting the ball, holding the ball and hitting the ball and hitting the ball.
The movement of anti-hand grip technology is:
A. On the basis of the outbound shot, take the ball handle slightly, the thumb is on the wide surface of the handle, (photo) Increase the stage of the backrest of the stage, the thumb is topped in the inside of the handle On (the position of the tiger mouth is right), the food is not close to.
b, when hitting the ball, the little finger, the ring finger, and the middle finger the handle, and quickly push the energetic hit before the thumb.
C, the grip should be relaxed, and there must be a certain gap between the palm and the handle.
Teaching steps:
<1> Check the original grip
Check that the original grip can first understand the students' grip habits. Master the cause of the error when correcting the error grip.
There will be several incorrect grip: holding a boxing grip, holding a slophoto grip. (Error grip photo)
<2> explanation, demonstration grip
The order of explanation can be segmented according to personal habits: (front demonstration and side demonstration photos)
Explain some parts of the grip:
1, the part of the grip.
2, the backhand grip is the position of the end of the handle: holding the lower end of the handle, the small fish on the palm of the handle. Double grip can hold some.
3, the position of the thumb at the mouth of the handle when the backhand is grip.
4, the palm of the palm and the face should have a gap when grip.
5. The conversion of the back of the arm.
<3> Positive Hand Grouting Exercise
Skilled and mastering positive hand shot technology
1. When turning the grip, use the eye to watch the grip action. Immediately adjust to the correct handheat technology action after hearing the pause, it is easier to master the positive hand shot technology under the visual action.
2, different eyes are concerned, pass the position of the handles to the handle of the handle, and immediately adjust to the correct master grip technology.
Skilled and mastering anti-gripping technology
1. When turning the grip, use the eye to watch the grip action. Immediately adjust to the correct backrest technology action after hearing the paused password, which is easier to master the anti-gripping technology under visual action.
2, different eyes are concerned, pass the position of the handles through the palm of the hand, immediately adjusted to the correct anti-hand grip technology action.
<5> Zheng, anti-hand grip conversion exercise
Correctly mastering the backup portrait, and skilled quickly and quickly
Fast adjustment is a master or backhand grip movement after hearing the password.
<6> Positive hand hold into force exercises
Learn the simple force of the master's grip based on the grasp of the grip movement (leading to pick up high ball strength photos)
Learn the simple force action of learning anti-hand holding on the basis of holding a grip action (backhand picking high ball strength photos)
Preparing posture: The right foot is before, the left foot is behind, and the left foot is in front of the right foot.
Positive hand is back: the right hand is extended forward, and the front arm is doing an extricuary, and the head is turned to the right to make the racket head down, the wrist is launched. When the ball is hitting the front arm, the bucket does the wrist, and the wrist is anesthetic and generates the ball.
Easy to be wrong: the wrist does not force a force, the forearm is doing an elbow action or to do an end to the axial straight arm up.
Anti-Hand Ball: When the right hand is extended forward, the front arm is doing a buffore action, and the head to the left down to turn the ring to make the racket head down, the elbow is sent forward, the forearm is naturally swing. When you hit the ball, do the external rotation of the arms in front of the axis while doing a handwrace to perform the front and move forward, and force the ball.
Easy to mistaken: The grip does not conversion or the hand hold, the elbow does not send it, and the elbow will have the movement of the elbow to produce the movement of the ball, and the head does not send the hitting point to the body too close.
1. Positive hand small force
Reduce the efforts to make students more attention in front hand hold movements and small power hitting movements
2, the strength of the hands and other strengths
Based on the basis of the basic master, the power is gradually increased, and the action is more skilled.
3, positive hands, medium strength, alternate, upload exercise
Skilled the positive hands and the actions, while strengthening the control of the grip and the up-reverse operation under the change in hitting power.
4, backhand small force
Reduce the efforts to make students more attention in anti-hand grip movements and small power hitting movements
5, anti-hands medium strength
Based on the basis of basic mastering and power, gradually increase the strength of the upload, making the action more proficient.
6, anti-hands, medium strength, alternate, upload exercise
Make the backhand grip and the uparting movement, while strengthening the control of the grip and the up-reverse operation under the change of the hitting force.
7. Positive, anti-hands alternating upload exercises
Anti-hand shot alternately, the refore finger and the thumb of the thumbs are skilled. On the basis of the top 6 exercises, the action is more skilled and converted natural.
Second, the key points of the teaching technology
1, put the shot to relax
2, the back of the opposite hand is flexible and accurate.
3, cooperate with the power action to make a grip and fast force action.
Third, the difficulty of holding the teaching technology
Positive hand hold: Positive hands and high ball hit the ball to face the net, need to turn over. If you have a high-tech, you will feel very twisted when you hit the far ball. Adjust the grip when it is hitting the far ball, not a knocking of the wrist.
Workaround: Strengthen the exploded action waves. Repeated multiple times and pilot - put the wrist.
Backrest: The anti-hand hold movement is better. But when playing, it is necessary to combine the actions of the wrist. The difficulty lies in piloting the action, and the pilot action before the backhand hitting is easy to generate one of the wrong links. (photo)
Grip control: The grip is too tight action. It is inevitable, affecting the coordination of whipping action. The grip is too loose, the ball is weak, the pace is slow, and the ball is not fast.
Fourth, the teaching method of grip technology
1. Observe: Imitate the exercise of the teacher's grip movement.
When demonstrating students, pay attention to the location, index finger, and change method of the study, index finger, middle finger.
2. Comparison: The students are inspected with each other.
The actions of their own movements and other classmates are controlled and corrected with each other.
1. On the basis of mastering the correct grip, let the students use the grip hand to turn the handle, look at the handsheld with the eyes, and immediately consciously adjust the original hand. The purpose of turning the grip is to make the grip can be quickly and accurately adjusted in the transition into a master or backhand grip.
2. On the basis of watching the turning grip, you don't need to look at it, and turn it entirely through your own body feels to complete the grip conversion. There are several ribs and corners on the handle, and the palm has passed the racket with the grip. Turn through the grip of the palm to adjust the right back.
3, by shouting "hands-on" "anti-hands", let students quickly reflect and adjust to the correct grip posture. V. Common errors and corrective methods in grip technology teaching
1, five fingers and get a boxing "boxing". Holding the punch will lead to the force of the muscles of the arm, which causes the muscles of stiffness, affects the flexibility of the wrist, and the out of the actions.
2, the grip hold is too high or too low. When the grip grip is too high, the hand to the racket head is shortened, reduces the power arm, affects the strike action. Holding too much racket is easy to get out of the beach.
3. When the front hand holds, the tiger port does not align the inside of the shot.
4, the thumb is attached to the inner side of the shot;
5, the palm is not left void;
6, the forefinger stretches when the front hand holds too straight, no to the thumb.
The thumb is attached to the handle when the backhand is shot.
