[The role of the arm protection] What should I do if I have the arm muscles and the muscles of the arm protection?

1. What are the effects of the arm protection armor?

The arm protection is no stranger to people who love to play basketball, but many people may not know much about the effect of arm protection. Most of them think that the role of the arm protection is used to pretend.EssenceEssence

Because I often see on the wild stadium, the whole body basketball equipment is complete, and the equipment party is in place from head to toe, but the ball skills are the equipment party.

Of course, the role of the arm guard is not only as simple as pretending:

1. Keep the tightness of the arm temperature and muscle. The temperature is to ensure that the energy of the arm is not easy to lose. The tightness is to keep the muscles that adapt to the state of strenuous exercise.

2. If you often bring a ball breakthrough and do not want to leave the nail seal or palm print on the arm of the usual hand, you can bring an additional arm protection arm.

3. The arm protection has a protective effect on preventing the re -injury after strain.

4. Aesthetic effect.

Sometimes it is found that the general offensive shooting players who take the most offensive means and the players who like to break through have the habit of carrying the arm protection. While maintaining the muscle tightness, you can also maintain the feel when you are shot.

2. What should I do if my arm muscles are strained

After muscle strain, first confirm the severity, lift your arms, or shake your arms to see if there will be severe pain.In general, after muscle strain, the pain is painful. With your hands, you can touch the cable -shaped hard block formed by the tension of the muscles. The pain is obvious, the local swelling or subcutaneous bleeding, and the activity is obviously restricted.

If it is just a slight strain, it feels not very strong, but it will hurt when taking heavy objects or raising the arms. It is recommended to apply hot compresses in the most painful point. After the hot compress, it will be reduced a lot. It will be fine in two days.

The moment the muscle strain feels severe pain, it is necessary to treat it immediately, and use cold water to rinse the local or wrap the ice with a towel until the pain and hotness are reduced.

After cold compresses, use a bandage to wrap the damage part properly to prevent swelling.

Slowly relax the muscles of the damage and raise the wounded limbs, you can take some pain relief and hemostatic drugs.

After one day, dismantle the bandage and according to the injury, you can affix the blood circulation and swelling and the swelling plaster. You can massage the damage locally with a relatively lighter method.

If the muscles are severely strained, if the muscle abdomen or tendon is pulled out, you should go to the Hospital for surgical sutures. Do not handle it yourself.

Is basketball goggles useful?

2. The pupil distance is suitable: the frame and the eyes should be controlled within 10mm. For example, your pupil distance is 65mm, so it is best to choose a mirror-frame pupil distance of 62-72mm.

3. Frame selection: Be sure to pay attention to the degree of curve.

4. Anti -fog problem: It is almost impossible to buy an anti -fog agent, because myopia lenses are almost impossible.If there is no anti -fog agent, when you run in winter, there is a white, very sad.
