How to analyze golf movements in sports anatomy should be detailed. Let's talk about the action analysis of up and down.

The whole content of the swing action includes back swing or back swing-up swing-swing apex-hem-impact take-homeopathic action-ending action.

(1) Rear Swing Bar

It refers to the action of swinging the club head to the upper back of the ball from the state of preparing to hit the ball, from the beginning to the action of bending the wrist. The back swing is the beginning of the up swing.

Make the left arm and the club into a whole, do not bend the wrist and elbow, and keep the triangle formed by the two arms and shoulders. The left shoulder and left hand form a whole with the club. Use the left shoulder to drive the arm, hand and club in turn, and slowly swing the club head to the right rear of the ball flying direction about 30 cm. In this process, it is necessary to keep the club face always facing the flying direction of the ball.

(2) Swing upward

On the whole, there is no gap and no pause between the back pendulum and the upper pendulum. The back pendulum is the beginning of the up pendulum, and the up pendulum is the continuation of the back pendulum. It can even be said that the back pendulum is part of the upper pendulum. After swinging backward, keep the triangle formed by the shoulder and the two arms, and use the club head to drive the two arms and the left shoulder to rotate to the right. When both hands reach the height of the right waist, the left arm will continue to lift up as if reaching the upper right. The left armpit is clamped, the upper arm of the right arm is basically fixed, the right armpit is clamped, and the elbow bends slowly with the lifting of the left arm. The left shoulder continues to rotate to the right under the drive of the left arm, and at the same time drives the left waist and left hip to twist to the right. Under the rotation of the upper body and buttocks, the left leg twists inward, the left knee flexes and the thigh muscles tighten. Under the action of torsional force, the right leg is still buckled and the distance between the knees is maintained, so as to resist the tendency that the right leg is twisted to the right, so the right leg is fully twisted and compressed like a spring. The inside of the right foot bears most of the weight, and the rest is borne by the inside of the forefoot of the left foot. In the process of up swing, the head and neck are integrated with the spine, so it can be assumed that the central axis of the twisting movement of the body passes through the neck, back and waist from the head to the top, and finally reaches the sacrococcygeal region. Keep your eyes on the ball, keep your head and neck still, keep upright, don't sway or twist from side to side, and finally put your left shoulder below your chin.

During the swing, the left arm should always be in the state of hitting the ball, the elbow should not be bent, and the wrist should be straight. If the elbow is bent, the swing amplitude will be reduced, which will easily lead to insufficient rotation of the left shoulder and reduce the impact of hitting the ball; If the wrist is not straight, it will affect the trajectory of the swing and cause all kinds of mistakes. Bending elbow and wrist is the most common mistake for beginners, which needs special attention.

(3) Swing vertex

Because the swing is very fast, there is no obvious time division between the upper swing and the lower swing, and their conversion is only completed in an instant, so we regard the moment of their conversion as the peak of the swing.

When the backswing is completed, the wrist of the left hand remains upright, flexes in the direction of the thumb, and the heel of the thumb shrinks. The belly of the thumb is pressed on the grip of the club, and the middle finger, ring finger and little finger hold the club tightly. The back of the left hand is forward and upward, the back of the back of the hand is on the same plane as the forearm surface, and the wrist does not bend to the palm or back. The inside of the left elbow is slightly upward, the right elbow is slightly twisted inward, and the left and right axils are gently clamped. Turn your left shoulder 90 degrees inward, at the chin, and point to the right of the ball. The waist is twisted to the right, the right knee is slightly inward, the left knee is close to the right knee, and the left heel is slightly raised. The weight should be supported by the inner leg of the right foot to complete the peak of the swing.

(4) Swing downward

The downward swing can be simply described as the movement of the body's "clockwork" to the right due to the upward swing. The starting order of the upper swing is club head, arm, shoulder, waist and knee, while the lower swing is just the opposite, that is, starting from the lower body, driving the waist, shoulder, arm and rod into the lower swing.

Starting from the ground action of the left foot raised during the upward swing, the left knee is fixed and the left leg is strongly supported, forming a wall that can bear strong impact force, so that the elastic momentum and positive force of the lower limbs are transferred to the upper body. The twist of the waist when preparing to hit the ball. Under the action of lower limbs and waist, the left shoulder naturally rotates to the left, driving the extended left arm as a lever to pull down the club. At the peak of the swing, the left wrist is forced to bend to the thumb side at a smaller angle, and the club head remains on it, but the strength of body movement is forced to accumulate, waiting for the instant of hitting the ball, and the body weight gradually moves to the left. Pull the club to the height of the waist with both hands. The waist is like a wall, resisting the weight of the body's work, thus maintaining the stability of the body. In the process of getting off the pole, pay attention to keeping the left half of your body forward. First, we should start from the left lower limb and fix it, and then the right half will naturally rotate under the guidance of the left half. At the beginning of the downswing, we should not use our right arm too actively.

(5) Impact ball

The act of hitting the ball can actually be said to be part of the downward swing. At the moment when the shoulder turns to be basically parallel to the flight line of the ball, the left hand pulls the club to waist height. At this point, the accumulated strength during the downward swing is concentrated on the flexion of the wrist to the thumb. Under the strong cohesive force and the inertia force of downward swing, the two arms continue to restore to the state when they are ready to hit the ball, and the club head begins to fall at an extremely fast speed. Just when the arms reach the posture of preparing to hit the ball, the club head reaches the lowest point of the swing trajectory-the position with the fastest ball speed and the greatest impact, and quickly sweeps straight from the position of the ball to hit the ball. In the process of downswing, the back of the left hand, which gradually faces forward, faces the target direction at the moment of hitting the ball, and then changes to the left rear direction with the rotation of the shoulder at the next moment, while the back of the right hand changes from hitting the ball in the opposite direction to facing the target to facing the right front, with the body weight concentrated on the left leg, the head kept still and the eyes fixed on the position of the ball.

Pay attention to the following aspects when hitting the ball:

The hitting action is the ultimate goal of up swing and down swing, so the hitting effect is determined by a series of work before hitting the ball.

Figuratively speaking, the whole swing is actually a whipping action completed by the whole body. When whipping, physical strength is transferred from the arm through the whip rod, and finally momentum is transferred to the whip tip. The same is true in the process of hitting the ball. The whole body moves from the lower limbs, waist, shoulders and arms in turn, and the momentum is getting bigger and bigger, and finally it is transmitted to the club head. The club head moves fastest and has the greatest impact at the moment of hitting the ball. The mistakes of any link in the whole body at any time stage will be reflected in the hitting effect. Therefore, when there is a wrong ball, don't always simply consider the moment of hitting the ball, which will only make people more confused and puzzling. We must trace back to the source and find the root cause. Only in this way can we make rapid progress.

Don't consider hitting a point when hitting the ball. Generally, novices may be relaxed and beautiful when they swing short, but when they hit the ball, they tend to focus on the static ball, that is, the impact on a certain point, and this strong consciousness will prompt players to try their best to swing, and the result will be extremely bad in nine cases. Therefore, experienced people often measure a person's technical level by comparing the difference between empty swing and playing. High-level people swing and hit the ball basically close to the empty swing, and the poor are very different. Therefore, the consciousness of hitting the ball should be diluted as much as possible, and the hitting action should not be regarded as hitting a point, but hitting a line or a narrow area. Hitting the ball only occurs in the process of the rapid movement of the club head in the swing trajectory. Before and after hitting the ball, make the club head move in a low and long straight line facing the target direction, and then send the club head directly to the target direction 10 to15cm after hitting the ball, so as to make a good shot.

(6) homeopathy

After hitting the ball, the weight is completely supported by the left leg, and the inside of the left leg is tense, so that the left knee is fixed and does not move to the left. The right heel is lifted, the right knee is close to the left knee, and the waist continues to rotate to the left under the push of the right leg. The body still rotates around the axis, and the right arm gradually takes the place of the left arm. Driven by the club head, the right arm straightens and pulls the right shoulder to move under the chin. Hold the club tightly with your left hand and put it under your left armpit. The front of the left upper arm rotates upward, keeping the triangle formed by the two arms and the shoulder. The back of the left hand is facing the left rear, and the club head swings outward in the target direction. When the hands reach the waist position, the head keeps the state when hitting the ball-that is, the state when aiming at the ball, and the eyes still look at the position of the ball before hitting the ball.

Homeopathic action should be regarded as the continuation of hitting the ball, and the subsequent action after hitting the ball should not be considered irrelevant. In fact, you don't have to look at the flying direction of the ball when you play, but you can judge the hitting effect by looking at the homeopathic action of the player after hitting the ball. It can be said that the correct up swing and down swing plus the correct homeopathic action can ensure the correct hitting action. No matter how to correctly swing up, down or even hit the ball, as long as there is a mistake in the homeopathic action, it will be abolished. After entering the homeopathic action, first of all, we should pay attention to keeping the rotation axis of the body motionless during the swing, and the body weight is concentrated on the inside of the left foot, so that the left knee is naturally fixed. If the weight is concentrated on the outside of the left foot, it will inevitably lead to the left knee moving to the left, and the center of gravity of the body will be unstable, resulting in the end movement not being completed correctly. In addition, after entering homeopathic action, the right arm straightens out and drives the right shoulder to rotate to the left under the traction of the low and long club head issued in the target direction. It is particularly important to note that at this time, the head should still be kept ready to hit the ball, fixed, and the eyes should be fixed on the position of the ball before hitting the ball.

(7) End the operation

After the hands reach waist height, the right arm continues to drive the right shoulder to rotate downwards, the club head moves to the left, back and up, the right arm keeps straight, the back of the left hand goes forward and up, the left armpit is clamped, and the left upper arm basically faces up. The left arm bends upward at the elbow with the upward movement of the right arm, and the waist and shoulders turn to the left. The body weight is borne by the left leg, and the left knee remains fixed. The weight supporting part of the left foot is transferred from the inside of the foot to the outside of the heel. When the right arm reaches the straight height of the right shoulder, the head turns to the target direction with the rotating shaft, and the eyes are fixed on the flying ball. At this point, the club head has moved to the highest point of the end action and continues to move to the left. Under the traction of the club head, the right arm swings upward to the left, and at the same time drives the right shoulder forward, and the body completely turns to face the target direction. The left arm bends, basically forming three right angles, that is, the upper arm and forearm are at right angles at the elbow, and the upper arm and shoulder are at right angles at the shoulder; The upper arm and trunk are at right angles in the armpit. The right arm bends slightly naturally, puts the club on the back, heads toward the target direction, and eyes watch the ball fly down.

The ending action is not deliberately made, but the natural result of a correct, smooth and rhythmic swing. At the end of the action, the weight should be completely supported by the left leg. If the center of gravity is still on the right foot after the action, it is easy for the high ball or the ball to rotate to the right. After the action, the body should face the target direction. If the waist is not completely facing forward and is tilted to the right, it means that the body is not rotating enough and it is easy to have a ball that rotates to the left. The left arm should maintain a certain tension during bending, and the armpit should not be opened. After the action, don't make your hands go beyond your left shoulder, too outward.
