? No glasses? The provisions of
Basketball is a fierce sport, especially when playing games, wearing glasses has become a very dangerous thing. When children concentrate on playing games, they are likely to accidentally knock off their glasses or break them. This is not the most dangerous. The most dangerous thing is that broken glasses will hurt your eyes. Maybe everyone doesn't care about a pair of glasses, but our eyes should be protected. All parents and children must pay attention to it! Our club forbids children to wear glasses when playing basketball.
On the one hand, taking off glasses and playing basketball can exercise the contraction of children's lenses and improve their eyesight to some extent. On the other hand, we suggest that highly educated children who can't see clearly without glasses wear sports basketball glasses. Sports glasses refer to safety glasses worn in sports, which have the effects of safety (PC lens-space film, which is a kind of lens with safety 100%), protection (TR-90 frame, which is soft and elastic), comfort (anti-slip nose pad and foot cover) and beauty (with sports and leisure clothes). Traditional optical glasses can only make up for vision, but can't really protect eyes, and there are layers of hidden dangers: First, they are easy to fall off; Second, it is easy to deform; Third, it is easy to break (or break).
This may cause various injuries to the eyes: 1. Corneal abrasion
2. Iris inflammation
3. Preocular hyperemia
4. Traumatic cataract
5. Retinal swelling
6. Broken eyes and so on.
Therefore, our club strictly prohibits children from wearing ordinary optical glasses when playing basketball, so as not to cause unnecessary harm. I hope all children and parents understand and cooperate, and everything is for health.

Prevention of muscle strain in exercise
0 1
Full warm-up preparation
If you don't want to strain your muscles during exercise, then adequate warm-up preparation is necessary.

Know how to rest at the right time
If you feel abnormal pain in a certain part during exercise, you must not continue. You should completely relax and rest, so that your muscles can be fully relaxed.
03
After you feel slight pain, be sure to find the wound.
Turn the painful part gently and do some gentle movements to determine which part of the muscle is injured, so that you can carry out targeted treatment and avoid the injured part during exercise.
04
Don't burden the wound.
In other words, you should try to avoid injury during exercise, even if it is only a slight pain, but if you increase the burden, it is likely to turn into a serious muscle strain.
05
Promote blood circulation at the wound.
Avoiding the wound doesn't mean you can't let it move. You can do some gentle exercise or massage for the wound to promote blood circulation.
06
Gently stretch the injured part.
Slowly stretch the wound until you encounter a slight collision, and then try to relax the injured part. When you do this, try to stretch further. When the muscles are stretched and relaxed, more blood will flow there for treatment, and you can heal faster. But if you stretch too much, it will lead to the wound getting worse and even getting injured again.
