4. What is injury?

5. Any damage to your body is an injury. Injuries can be caused by
accidents or acts of violence, and may occur at home, work, or play.
They can be due to impact from blunt objects or from objects that
penetrate the body. Common types of injury include abrasions,
lacerations, hematomas, broken bones, joint dislocations, sprains,
strains, and burns.

6. CAUSES OF SPORT INJURIES

7. • Sports injuries are most commonly caused by poor training
methods; structural abnormalities; weakness in muscles, tendons,
ligaments; and unsafe exercising environments. The most common
cause of injury is poor training. For example, muscles need 48 hours
to recover after a workout. Increasing exercise intensity too quickly
and not stopping when pain develops while exercising also causes
injury.

8. COMMON ACCUTE INJURIES

9. SPRAINS
•Are overstretched ligaments that
stabilize and limit joint mobility.

11. STRAINS
• Is a twist, pull, or tear of muscle or tendon(a tissue that connects the
muscle to the bone).

13. FRACTURE
• Are more common in growing bones because it is less dense.

15. DISLOCATION
• Commonly occurs in joints that allow greater range of motion.

17. CONCUSSION
• Are life threatening injuries because they disrupt the normal function
of the brain.

19. OSTEOARTHRITIS
• Tear of joint that results to its deterioration, the friction deteriorates
the cartilage that protects the bones from rubbing against each other.

21. BURSITIS
• The bursa is a sac like musculoskeletal structure that provides support
and cushioning to the joint. This injury is common in swimmers and
runners.
