What are we going to learn today?

Today we are going to learn: 

What types of sports related injuries there are. 

How you can prevent sports related injuries. 

Training

Playing sport exists for a long time. It is fun and it keeps your body healthy. You also get better at something. When you are playing sport, you are generally training 3 things: strength, stamina or coordination. 

Training

You can also train other things like playing an instrument. When you repeat the same movement a lot it will be stored in your motor memory and it will become an automated movement.

Types of injuries

Sports related injuries occur when you are moving your body a lot/in a wrong way, overloading them. That way you wear down the used organs more. There are 3 types of sports related injuries:

- Joint injuries

- Muscle injuries

- Bone injuries 

RSI

RSI is starting to become a more common injury. You can get this by repeating a lot of the same (fine) movements. Symptoms for it are pain in the hands, arm, shoulder and neck. 

It is more common now because of computer and phone usage. 

Prevention

You can minimize the risk of having sports related injuries by doing some activities before and after activity; a warming up and cooling down. By doing this, you ''start'' and ''shut down'' your body gradually. By doing stretch exercises you minimize the risk of overstretching a muscle.
