What are the components of a complete lateral slide step shot put

Hold the ball in your right hand, face the left side of your body in the direction of the throw, swing your left thigh in the direction of the throw, kick your right leg off the ground, slide your right foot along the ground to the center of the throwing circle, and your left foot will quickly hit the ground to form a final force starting position.

Then, push your right foot quickly so that your right medulla turns in the direction of the throw and lift your upper body sideways. When the left side of the upper body moves to the ground perpendicular to the ground, the legs are quickly extended, the left arm is braked on the side of the body, and the right chest is lifted at the same time, the right shoulder is sent, and finally the ball is quickly pushed out with the right arm. When the ball leaves your hand, lower your weight and swap legs to maintain your balance.

It is mostly used by beginners.

There are three main techniques for pushing the shot put: pushing the shot put with your back on the spot, pushing the shot put in a high position, and pushing the shot put in a low position.

1. Push the shot put with your back on the spot

One of the types of shot put is to turn your back to the direction of the throw, turn your torso and shoulder straps to the right, lean your upper body forward, shift your weight to your right leg, and extend your left shoulder and left arm forward and buckle slightly inward.

2. Push the shot put in a high posture

3. Push the shot put in a low posture

Hold the ball with your back to the direction of the throw, stand in the circle near the back edge, stand with your feet at a distance of 50 cm from back to back, land on the ball of your front foot or toes, and point your right toe in the opposite direction of the throw close to the circle, your left arm will hang down naturally, your left shoulder will be slightly buckled, your legs will be full, and your upper body will be stretched forward.

Shot put

The shot put is one of the track and field sports that uses the strength of the whole body of the human body to push a certain weight shot put from the shoulder with the arm.

The shot put originated from the activities of ancient humans who used stones to hunt animals or defend against attacks. The modern shot put began in the 40s of the 14th century when European artillerymen were playing and competing in the leisure time of shell throwing, and gradually became a sport. The men's and women's shot put were included in the Olympic Games in 1896 and 1948 respectively.

In the 50s of the 20th century, American athlete Parry O'Brien invented the technique of pushing the shot put with a back-slide step, which was called "a revolution in the history of the shot put".

The shot put technique is divided into five parts: holding the shot put, preparing the position, sliding step, and finally exerting force and maintaining body balance techniques.

There are two ways to hold the ball (for example, with a right hand).

1. Separate the five fingers naturally, place the ball at the base of the index, middle and ring fingers, support the thumb and little finger on both sides of the ball, and fully bend the wrist backwards. This increases the stability of the ball, prevents the shot put from sliding, and gives full play to the strength of the wrist and fingers, but the fingers are slow to bounce the ball. This method is recommended for beginner shot putters and female athletes with poor finger strength.

2. The five fingers are naturally disturbed, the ball is placed in the ball socket formed by the index finger, middle finger, ring finger and little finger, the thumb is close to the lower part of the back of the ball, and the wrist is dorsiflexed. This can make the finger strength relatively concentrated and increase the speed of whipping, but the shot put is easy to slip the hand, and the holding posture has a large bearing force on the wrist. This method is recommended for athletes with good finger and wrist strength and good coordination.

The technical essentials of pushing the shot put with a back-slide step are as follows:

1. Hold the ball in your right hand, turn your back to the direction of the throw, swing your left thigh backwards, kick your right leg off the ground at the same time, slide your right foot along the ground to the center of the throwing circle, then quickly buckle your right leg inward, and land your left foot on the ground with your left foot on the inside, forming a posture of starting with your back to the end.

2. Then, the right foot is rotated, and the right cell rotates in the direction of the throw, so that the hip axis rotates more than the shoulder axis, and the upper body forms a tight posture. When.

1. Learn and master the technique of holding the ball.

3. Draw a long straight line along the throwing direction, let the students stand with their backs to the throwing direction, stand close to both sides of the line with their feet apart, and do the practice of high posture and low posture back to slide and push the shot put with their bare hands.

The essentials of the side-slide step push shot put action are divided into force sequence and action steps, as follows:

1. Force sequence:

First, the back leg is tested and the leg is pressed, then the hip is turned, then the chest is raised, then the shoulder is topped, then the hand is pushed, and finally the fingers are flicked.

2. Action steps:

For example, if you are right-handed, you should first hold the ball in your right hand, face the left side of your body in the direction of the throw, swing your left leg in the direction of the throw, and place your right foot in the center of the throwing circle, with your knee slightly bent to form the starting position of the last force. When the left side of the upper body moves perpendicular to the ground, the legs are quickly extended, and then the left arm is braking, and the right chest is lifted at the same time, and the right shoulder is sent to the right shoulder, and finally the right arm is quickly pushed out of the ball with the right arm. Once the ball is out of your hand, lower your center of gravity and swap legs to keep your body balanced.

Notes for throwing shot put in a sideways step:

1. When throwing, the body must be sideways towards the direction of the throw, and the ball can only be held in one hand.

2. Do not step on the line after the throw, otherwise it will be regarded as a foul.

There are two main forms of shot put pushing techniques used by athletes: back sliding step push shot put and back rotation shot put.

Specific methods: 1. Holding the ball method The fingers are naturally separated, and the ball is placed at the base of the fingers of the index finger, middle finger and ring finger, and the thumb and little finger are naturally supported on both sides of the ball. Bend your back with your wrist to prevent the ball from sliding and control the direction of the ball.

Once you have caught the ball, place the ball on the clavicle fossa of your shoulder, attach it to your neck, turn your hand slightly outward, turn your palm forward, and bend your elbow.

2. The preparatory posture before sliding (or rotating) can be divided into two types: high posture and low posture. High Stance: Stand near the back of the circle with your back to the throw after receiving the ball.

Spread your feet back and forth, about 20 cm to 30 cm apart, and the end of your right foot is nearly round, towards the direction of the heel throw.

If you want to throw the shot put, you not only need a certain physical fitness, but also need to train special strength and speed, and many people want to know what are the main techniques of pushing the shot put? In fact, the technique of pushing the shot put mainly has three kinds of in-situ back, high posture and low posture, taking the in-situ back-to-back shot putting training method as an example, first do 1 or 2 turns, after the rotation is completed, the right foot kicks the ground, and then rotates the hip joint, the upper part of the body is lifted, and the center of gravity of the body is moved while throwing the ball, the left foot is on the ground, and the outside of the foot is against the ground. Tips:

After the rotation is completed, push the ground with your right foot hard, rotate your hip joint in the direction of the pitch, and lift the upper part of your body quickly.

The technical advantage of the back slide shot put over the side slide shot put is that it lengthens the distance the ball travels before the shot is taken

Lengthens the running distance, so that the shot put gains maximum muzzle velocity.

Related knowledge: With the practice of athletics and the development of sports science, the technique of shot put has been continuously improved and perfected. Coaches and athletes started from the most important factor that determines performance, speed, reformed the technique, from the ancient step-up putting method, to the side-slide push, and in the early 50s, it developed from side-to-side putting to back-to-back putting.

As soon as this method appeared, it was widely used by shot put players, because it changed the lateral direction of the body from 90 degrees to 180 degrees, so that the distance of the shot put players in the run was greatly extended, and it could produce greater speed, and was used in the final shot, thus promoting a significant improvement in athletic performance, and it exceeded the 20-meter mark in the 60s. Therefore, the back-to-back throwing method is a major revolution in the technique of pushing the shot put.

In the more than 10 years since the advent of the back-sliding step pushing method, many athletes have shown different technical characteristics on the basis of this method, which has led to the development of the back-facing technique by twisting and tightening the upper body more fully at the end of the force, so that more muscle groups can be exerted when pushing the ball, so that more speed can be obtained when the ball is left in the hand.
