Why is the snatch more laborious than the clean and jerk, and the difference between the snatch and

When our teacher was talking, I just remember talking about getting a lot of initial velocity in the snatch. What he said, some words I didn't hear, some words that I didn't know yet, the initial velocity, we hadn't learned yet, and I didn't understand it very well. Hopefully, tell me why.

The clean and jerk mainly depends on the elastic force n, and the snatch mainly relies on the friction force f, assuming the same acceleration, then n should be equal to fIf you haven't learned about acceleration, follow a constant velocity.

n=mg, f=mg, so n=f, but to produce mg size f during the snatch, it needs a much greater elastic force n than f'Back it up.

Because f n', which is the relationship between the frictional force and the elastic force to produce the frictional force.

So the forces required to snatch are f and n'The resultant force is up.

So it takes a lot of effort to snatch.

Of course, in fact, the snatch is not all F to balance the gravity, there is still a part of the elastic force. I'm just trying to make a simple judgment about the relationship between the two, so I think it's just f to balance gravity.

Both the snatch and the clean and jerk are a type of weightlifting, but there is a big difference between the two.

Different movements: In the snatch, the athlete puts the barbell parallel to the front of the two calves, and the two hands collide with each other to lift the barbell from the weight table; The clean and jerk is to first place the barbell on the horizontal line of the center of gravity of the body, bend the legs and squat, lift the barbell, put the barbell on the shoulders through the chest, and then stand, and then hold the bar with both hands, bend the arm, the chin is level with the bar, and the straight arm is pushed up, and the action is completed. The different steps: the snatch is to lift the barbell in a continuous motion; Whereas, the jerk is the use of two decomposition movements to lift the barbell. Different snatches require the barbell to be in a position where the arms are fully extended and on the head; The clean and jerk requires you to first lift the bar to your shoulders, stand with your body, and then lift it above your head.

The snatch and clean and jerk are the two scoring items in weightlifting competitions, and the main difference is the consistency of the movements.

Snatch: The athlete places the barbell parallel to the front of the two calves, hits the bar with both hands, and lifts the barbell from the weight table in a continuous motion until the arms are fully extended on the head. In a lift, the player is asked to straighten his arms and lift the barbell above his head in a continuous motion, while in the clean and jerk, the player needs to place the barbell on his shoulders and stand upright.

Clean and jerk: The athlete lifts the barbell above the head in two broken movements. Place the barbell on the level of the center of gravity of the body, bend the legs and squat, lift the barbell, place the barbell on the shoulder through the chest, and then stand; Then hold the bar with both hands, bend the arm, the lower jaw is level with the bar, and the straight arm is pushed up, and the action is completed.

At the Olympics, only the snatch and clean and jerk are counted, and the order of entry is based on the weight required, the order in which the athletes are drawn and the number of lifts. The number of attempts for athletes in the snatch and clean and jerk is 3 times. If the overall score is the same, the one with the lower weight before the race will be ranked first, and if the same is the same, the one with the lower weight will be weighed first after the race.

The jerk is a pause at the shoulders and neck before lifting it above the head. Whereas, the snatch is lifted directly to the top of the head.

1. The snatch and the jerk both belong to weightlifting, and the snatch is a one-time action to lift the barbell directly to the top of the head; The clean and jerk is the use of two decomposition movements to first lift the barbell to the shoulders, stand with the body, and then lift it above the head; Both the snatch and the clean and jerk are achieved with the highest weight of three attempts.

2. The snatch is mainly for the athlete to put the barbell parallel to the calf, and use the tiger mouth of both hands to lift the barbell from the weight table in a continuous action, and the barbell needs to be straightened in both arms and located on the head. The snatch is a continuous movement to lift the barbell, and the height of the lifting is required to be on the head.

3. The clean and jerk is different from the snatch, which is to use the two movements of decomposition to lift the barbell to the top of the head, first lift the barbell to the parallel position of the center of gravity of the body, then bend the legs to squat, and then lift the barbell twice at the shoulder position, and then stand in the position of lifting to the top of the head to complete the action.

The jerk is a pause at the shoulders and neck before lifting it above the head. Whereas, the snatch is lifted directly to the top of the head.

Answer: It can be understood literally, the snatch is to grab the top of the head, and the jerk is to hold on first and then lift!

The clean and jerk has nothing to do with the chest, and the snatch has nothing to do with the chest, right?

The snatch is done in one go and there is still time to rest in the jerk.

Both the snatch and the clean and jerk are a type of weightlifting, but there is a big difference between the two, and the specific differences are as follows:

1. The action is different.

The snatch sliding lift is when the athlete places the barbell parallel to the front of the two calves, and the two hands collide with each other to lift the barbell from the weight table; The clean and jerk is to first place the barbell on the horizontal line of the center of gravity of the body, bend the legs and squat, lift the barbell, put the barbell on the shoulders through the chest, and then stand, and then hold the bar with both hands, bend the arm, the chin is level with the bar, and the straight arm is pushed up, and the action is completed.

2. The steps are different.

The snatch is the lifting of the barbell in a continuous motion; Whereas, the clean and jerk uses two decomposition movements to change the barbell lifting wheel.

2. The requirements are different.

The snatch requires the barbell to be in a position where the arms are fully extended and on the head; The clean and jerk requires you to first lift the bar to your shoulders, stand with your body, and then lift it above your head.

In the weightlifting competition, the highest weight lifted in the three attempts of snatch or clean and jerk is a single achievement, and the ranking is determined by the result. The overall ranking is determined by the sum of the snatch and clean and jerk, if the results are equal, the light weight before the competition will be ranked first; If the results and weight are equal, the athlete who lifted the weight first will be ranked first.
