Discussing sports-related injuries (TB page 108)

Making exercises 

Muscles can only pull, and not push.

1. True
2. Flase

Give an example of an antagonistic pair.

When you are a marathon runner, you mostly train ... muscles.

1. Fast twitch
2. Slow twitch

Where can you find involuntary muscle tissue in your body?

How come your heart gets bigger when you train more?

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. 

Types of injuries

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

- Joint injuries

- Muscle injuries

- Bone injuries 

Joint injuries

Joint injuries happen when you damage a joint. When you sprain something, you bend a joint beyond what is nomal. Throught that, you damage the ligaments around a joint. 

Joint injuries

When you have a dislocated bone, one bone within a joint is out of the place it normally needs to be in. With that, a lot of ligaments are also damaged. 

Joint injuries

When you have a soccer knee, the cartilage within a knee is damaged. This can happen when your foot stands still, but you move your upper leg. 

Muscle injuries

You can also injure your muscles. Most notable you can have muscle cramps (sudden contractions of a muscle), pulled muscle, or regular muscle ache. 

Bone injury

When you fall, or there is a lot of force on a bone in antoher way, you can break a bone, this is called a fracture. Bone can heal itself, but you need to keep it in a cast, so the bone doesn't move. 

Prevent

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.
