How many parallel bars qualifications does the PLA have?

Horizontal bar practice 12 qualified, 15 excellent. 15 parallel bars are qualified.

What are the advantages of hanging the horizontal bar?

One: Relieve low back pain.

When hanging the horizontal bar, you should hold the horizontal bar tightly with your hands, keep your feet off the ground, and your body droops naturally. Then hang it according to your own ability, about three times a day, and the hanging time should be controlled within 15-30 seconds. Later, the time and frequency of hanging the horizontal bar can be appropriately increased. After three months, you will find that the symptoms of low back and leg pain have obviously improved.

Two: increase the flexibility of the body.

Under the action of gravity, hanging the horizontal bar helps to stretch the body, thus enhancing the flexibility of the body. Hold the horizontal bar tightly with both hands, don't lift your feet off the ground, and hang your body on the horizontal bar with your chin slightly stretched and relaxed. This action is good for stretching your upper body. It will last for five seconds at first, and then gradually increase the time. During stretching, you should keep relaxed and not be too intense, so as not to cause muscle strain.

Third: exercise muscles.

When you hang the horizontal bar, you can exercise the muscles of your arms, abdomen and shoulders. Take the horizontal bar as a pull-up, in this process, you can exercise the muscles of your back, upper arms and shoulders well.

Fourth: help grow taller.

When the horizontal bar does pull-ups, the posture of the body stays naturally drooping, which can help the muscles of the back and waist. Tension and gravity in the process of confrontation can promote the growth of bones, so it seems that hanging the horizontal bar is helpful for height.

Horizontal bar protection technology

The commonly used help skills in teaching are: pushing, pushing, sending, blocking, dialing, rubbing and helping. According to the skill level and action type of the practitioner, individual or comprehensive methods can be used to help. For example, under the backward arc of the low horizontal bar, you should push and lift. No matter which operation method is adopted in horizontal bar teaching, the following requirements should be met:

1, hand direction should be correct when assisting. Horizontal bar movements are mainly swing and loop ball movements, especially loop ball movements. The helper must know the direction of the loop before making the hand, otherwise the protector's arm will be easily pressed on the barbell by the students because of the wrong direction of the hand, so attention should be paid to the protection. Take the loop before riding as an example. The helper must turn the L arm or wrist of the practitioner from under the pole with one hand to speed up the loop. If he takes his hand off the pole, it is easy to have an accident.

2. The hand position should be accurate when assisting. The correct part is the place where the power-assisted effect is the greatest, and the power-assisted point is generally near the total center of gravity of the human body or the center of gravity of the body parts on both sides of the motion axis. For example, when protecting and helping to support the ring, the helper needs one hand to support the waist (close to the general center of gravity of the human body), and the other hand to dial the thigh or shoulder (the center of gravity of the body parts on both sides of the motion axis) to help the ring.

3. Always be alert and appropriate when assisting. The timing of assistance should meet the structural requirements of the operation. Too early or too late to help will affect the success or failure of the operation, and even cause human injury. For example, when protecting and helping the swing of the suspended back, it is necessary to wait until the body's center of gravity swings above the vertical part before sending it, so it is easy for the practitioner to fall off the pole in advance and land with help.

4. The amount of assistance should be appropriate. Under normal circumstances, for beginners or people with poor technical level and weak ability, the help given is relatively large, and vice versa. If you give the same amount of help regardless of the object and specific situation, or think that the greater the help, the better, it will affect the mastery of motor skills.

5. The focus of assistance should be clear. Protection focuses on the key parts and the most vulnerable parts of the body. First the skull, then the upper limbs. Direct landing of the head and straight arm support must be avoided. In addition, the protection of waist, knee and tread can not be ignored.
