Middle School Students' Physical Education and Health Knowledge

First, how to prevent sports injuries

When it comes to sports injuries, we must first understand under what circumstances it is easy to cause sports injuries. I think there are the following aspects:

1, insufficient warm-up exercise

Nowadays, many students ignore everything when they are in a good mood, and start to do strength exercises or explosive sports without preparing for sports, which is the primary cause of sports injuries.

2. weather reasons

Running in foggy and dusty weather is easy to cause respiratory diseases; On rainy days, if you like to play on the open-air basketball court, it is easy to fall, from spraining your foot to falling all over. Try to avoid physical exercise in hot weather. If the competition happens to be arranged in hot weather, pay attention to ventilation, loosen clothes, replenish water, and drink drinks containing vitamin C, such as citrus juice.

3. Actual functions

Students who have just caught a cold are still very weak. In this case, a large amount of exercise is also easy to cause sports injuries. Female students are not suitable for jumping, swimming and handstand during menstruation. Otherwise, it is easy to have symptoms of stomachache. These sports knowledge should be explained to students.

4, site equipment reasons

At present, many schools in rural areas, due to the lack of maintenance of sports venues and rugged runways, are the main reasons for sports injuries. When it comes to equipment, it is even worse. Many schools, such as single parallel bars, are exposed to the outside for a long time without maintenance, and thick rust can easily damage students' hands. What's more, they are doing exercises at one end of the parallel bars, and the other end is actually tilted. The school has barbells, but they are not used for fixing.

5. Organizational reasons

Before class, physical education committee members or teachers should first check the sports ground to ensure that there are no hidden offenders on the sports ground, and try not to attend classes or train in the overgrown ground where it is not easy to find hidden offenders.

With the above knowledge and careful protection in sports, the occurrence of sports injuries can be greatly reduced. We tried to nip in the bud. What should we do if sports injuries still occur?

Second, how to deal with sports injuries, sports injuries are common in middle schools:

1, stab wound:

That is, stabbed by dirty bamboo or nails. If the stab wound is shallow, just disinfect the wound with hydrogen peroxide and then apply mercuric chloride. If the stab wound is deep, you must go to the hospital for tetanus toxoid vaccination.

2. Abrasions:

That is, the epidermis of the skin is abraded. If the scratch is shallow, apply red mercury; If the bruised wound is dirty or oozing blood, apply normal saline for debridement and then apply red or purple potion.

3. Muscle strain:

Injury caused by tearing of muscle fibers. It is mainly caused by excessive exercise or insufficient warm-up. The severity of the injury can be known according to the degree of pain. Once the pain is induced, stop exercising immediately, and apply ice cubes or cold towels to the pain points for 30 minutes to make the small blood vessels contract and relieve local congestion and edema. Avoid rubbing and hot compress.

4. Contusion:

Tissue damage caused by local blunt instrument. Minor injuries do not require special treatment. After 24-hour cold compress treatment, Chinese patent medicine and physical therapy can be used to promote blood circulation, remove blood stasis, reduce swelling and relieve pain.

5, sprain:

The ligament attached to the joint is torn due to sudden excessive torsion of the joint. Most of them occur in ankles, knees, wrists and waist.

A, acute lumbar sprain, let the patient lie on his back on a thick wooden bed, with a pillow under his waist, first cold compress and then hot compress.

B, joint sprain ankle joint, knee joint, wrist joint sprain, first will be high sprain, cold compress for 2~3 days before hot compress. If the sprained part is swollen and the skin is blue and painful, please refer to "muscle strain".

6. Dizziness:

It is common for students to feel dizzy during middle and long distance running. The reason is that for students with weak constitution, they feel dizzy because of the lack of oxygen supply to their brains for a short time. Take the students to a ventilated and cool place and let them lie on their backs. Ginger tea can generally be taken.

7. Dislocation:

Joint dislocation. In case of dislocation, the patient should be told to keep quiet, do not move, do not rub the dislocated part, and send it to the hospital for treatment after proper fixation.

7. Fracture:

There are two kinds of common fractures. One is that the skin is not broken, there is no wound, and the broken bone is not connected with the outside world, which is called closed fracture. The other is that the bone tip passes through the skin and there is a wound communicating with the outside world, which is called an open fracture. For open fractures, hand traction is not allowed to avoid osteomyelitis. After the wound was initially bandaged and stopped bleeding with sterile gauze, the upper and lower joints of the limb fracture site were fixed with wooden boards and plastic plates. Suspected spinal fracture, you should lie on the door panel or stretcher as early as possible, and pad your torso with clothes and sheets. To avoid moving and lifting the head of the injured person, causing spinal cord injury or paraplegia. When a cervical fracture is suspected, pillows should be placed on both sides of the head and neck or the patient's head and neck should be supported to prevent it from shaking during transportation, and then fixed with a flat plate and sent to the hospital for treatment.

Mental health knowledge of middle school students
