Homework 4.6

Asgmt 53-58

1. List 3 causes of sports-related injuries

1. Accidents: like a fall, hard blow
2. Not warming up
3. Using wrong equipment/techniques

 2. What makes sprains and dislocated bones similar, but also what makes them different.

Similarities

• Both are joint injuries
• A joint is stretched/bent beyond its limits

Differences

• Sprains happen more often
• Dislocated bones are more painful
• Ligaments might tear in sprains, are torn in dislocated bones
• Bones are much further apart in a dislocated bone
• A doctor is always needed with a dislocated bone

3. A soccer knee might end the career of a soccer player, explain why

A soccer knee is a serious joint injury. The cartilage in the knee tears.

It is not always possible to repair/replace the damaged cartilage.

It this is the case, the athlete will no longer be able to play soccer

4. You can pull a muscle and fracture a bone. 

How can these injuries heal and which will take the longest?

A pulled muscle has been (slightly) torn. 

The muscle will swell and sometimes bleed. Muscle-cells will need to rebuild the muscle.

A fractured bone is broken.

The bone tissue will need to be rebuilt. (this can be helped with a cast).

Repairing bone tissue takes longer than repairing muscle tissue

5. Name 3 things that can reduce the risk of injuries.

• Doing a warming-up before doing sports
• Stretching before and/or after doing sports
• Doing a cooling-down after doing sports
• Doing sports at your own level
• Being mindful of your techniques
• Getting enough rest
