Why do you have to stand alone on the left and on the right during tug of war?

The skills of tug-of-war are to have a good posture, a reasonable order, and a scientific grip on the rope.

Race skills. 1. Prepare the posture.

Hold the rope: the palms of both hands should be upward; Pull rope: the rope should be passed under the armpit; The toes must be in front of the knees, and the whole body should be stretched and straightened before the tug-of-war is ordered.

2. Standing. Don't be afraid of falling, and lean back as much as possible! Half squat, horse step, center of gravity pressed back. The center of gravity must be low, and the group leans back. To put it simply, it is to stick your abdomen or hips out of front and look at the sky with your eyes.

3. Sorting. Don't press the strength, but by weight, from the end of the rope to the front line, from heavy to light. Be careful to distance yourself to avoid stepping on.

Don't tire your arms and neglect your feet and legs, and be sure to stand firm! The front is more powerful, and the tail is heavier.

4. Hold the rope. Pull the rope to the straightest before the race, be sure! Otherwise, if the person behind pushes hard, the rope is bent, and the force will be neutralized.

Everyone's strength must be straight, otherwise part of the force will be offset by the strength of their own people, and the result will be half the effort. The two hands are 20 cm apart, depending on the length of the individual's arm.

Extended Materials. Knowledge of the physics of tug-of-war:

1. When encountering friction, first distinguish whether it is "static friction" or "sliding friction"! It is the sliding force that is subject to sliding friction that occurs in "relative motion".

2. If it is static friction, the value is obtained by using the force balance.

3. If it is sliding friction, it must be noted that its size only depends on the "roughness of the contact surface" and "the size of the positive pressure"! Also, nothing to do with other factors!

4. Stationary objects can be subject to sliding friction, such as the blackboard when wiping the blackboard, the ground when mopping, and the ice surface when skating, all of which are stationary but subject to sliding friction.

5. Moving objects can be subjected to static friction, such as grain on a conveyor belt.

The position of the person. The small man in front and the big man in the back cross positions in a T-step order. Separate for men and women.

Keep the balance of power on both sides! The front leg is 120 130 degrees, the back leg is 90 110 degrees, and the distance between the two feet is slightly greater than the shoulder, which can not only save space, but also ensure that the collective resultant force acts on the rope in a straight line. It is best to wear shoes with embossed soles to participate in the competition to bring out the best in everyone.

Second, the rhythm. Speed up the rhythm of the attack, use one-half of the beat, adopt the quick combat method of 1 force and 2 dull strength, do not give up an inch of land, press step by step, break the opponent's rhythm and overall tactics, put pressure on the opponent, and achieve the effect of surprising victory. Finally, seize the moment.

At the beginning of the game, it is necessary to stabilize the rope in advance, and the leader of the platoon is under unified command, at this time, you must not be careless, and try to prevent the opponent from exerting force in advance, so as to prevent you from being caught off guard and failing in a daze. 3. Rope grip: three points and one line, two hands plus the "back" armpit, tightly clamp the rope; The player in the back reaches through the armpit and holds the rope in the middle of the hands of the player in front.

Essentials 1Keep your palms facing up 2Do not separate the left and right hands 3

Don't push too hard 4The feeling of pulling to the side The power of the rope is almost transmitted to the rope through the hand (a small part is the armpit clamping force); The grip strength (staying power) of the hand is not great or not.

When tug-of-war, there is one person on the left and one person on the right, and if you stand like this, you can form a straight line, and when you pull, the force can be more even, and the force will be more concentrated.

When tug-of-war, stand on the left and stand on the right, in order to exert strength in one place.

Summary. When tug-of-war, why do you have to stand alone on the left and one person on the right, it is a tug-of-war competition, a fair competition, and on the other hand, it is necessary to prevent an injury to this person due to improper force in the process of this competition.

Hello, I have seen your question, and I am sorting out the answer, please wait for a while When the tug-of-war is carried out, why should a person on the left stand alone on the right This is a tug-of-war competition, a fair competition, and then the other party Xiang does a pat on the face, and the stool is prevented from being injured in this competition process due to this improper force.
