Lesson 2.3: Physical Activity and Injury

2. Lesson 2.3: Physical Activity and Injury
Lesson Objectives:
List and describe some activity-related physical injuries.
List some guidelines for preventing injuries during physical activity.
Explain how to apply the RICE formula to the treatment of physical injuries.

3. Lesson 2.3: Physical Activity and Injury
Question
Injuries can occur while playing sports or because you attempt to do too much activity. What are some common types of injuries?

4. Lesson 2.3: Physical Activity and Injury
Answer
Some common types of injuries are
chronic injuries, which result from overuse or over-training; examples include
shinsplints,
stress fractures,
tennis elbow, and
rotator cuff (shoulder) injuries.

5. Lesson 2.3: Physical Activity and Injury
Answer (continued)
acute injuries, which result from an accident that occurs while participating; examples include
spraining an ankle,
straining a muscle, and
breaking a bone.

6. Lesson 2.3: Physical Activity and Injury
Answer (continued)
Another kind of injury is called microtrauma. It is
a small but unseen and unfelt injury,
caused by risky exercises,
caused by wear and tear over time, and
the cause of muscle or joint injuries later in life.

7. Lesson 2.3: Physical Activity and Injury
Question
What is the difference between a strain and a sprain?

8. Lesson 2.3: Physical Activity and Injury
Answer
Sprains are injuries to ligaments (sprained ankle, for example).
Strains are injuries to muscles and tendons (strained hamstring muscle, for example).

9. Lesson 2.3: Physical Activity and Injury
Question
What is the difference between a sign and a symptom of an injury?

10. Lesson 2.3: Physical Activity and Injury
Answer
Signs are things the injured person or others can see:
bruising
swelling
bleeding
Symptoms are felt by the injured person:
soreness
sharp pain

11. Lesson 2.3: Physical Activity and Injury
Question
Injuries from physical activity occur most often to skin, bones, ligaments, and tendons. What is the difference between ligaments and tendons?

12. Lesson 2.3: Physical Activity and Injury
Answer
Ligaments are tissues that connect bones together.
For example, knee ligaments connect the bones of the upper and lower leg (femur to the tibia and fibula) (see picture).

13. Lesson 2.3: Physical Activity and Injury
Answer (continued)
Tendons are tissues that connect muscles to bone.
For example one tendon connects the muscle of the upper leg to the kneecap (see previous picture).

14. Lesson 2.3: Physical Activity and Injury
Question
When an injury happens, it needs to be treated. For injuries such as sprains and strains, what should be done immediately following an injury?

15. Lesson 2.3: Physical Activity and Injury
Answer
The RICE principle should be followed:
Rest
Ice
Compression
Elevation
