Study Notes
Causes of Sports Injuries
- Occur when an object encounters TRAUMA or PHYSICAL FORCE that is greater than what it can resist or absorb.
Direction of Forces Applied to Musculoskeletal Structures
- Tensile forces act away from the center of the structure, causing a pull or stretch.
- Compressive forces impact the center causing it to bend or fold.
- Shear forces are opposing forces toward the different ends of the structure causing it to twist.
Structure Function
| STRUCTURE | FUNCTION |
|---|---|
| LIGAMENTS | Stabilize joints |
| TENDONS | Attaches muscles to bones |
| MUSCLES | Creates movements |
| BONES | Anchor for muscles |
| JOINTS | Fulcrum for movement |
Sports Injuries
- ACUTE INJURIES - have signs and symptoms that manifest immediately after force application.
- CHRONIC/OVERUSE INJURIES - signs and symptoms occur after a long period of exposure to the force.
Acute Injuries
-
SPRAIN
- overstretched ligament.
- Ligaments stabilize and limit joint mobility.
- Common sprains: lower limbs & ANTERIOR CRUCIATE LIGAMENT (ACL)
- An individual usually feels a popping sound when a knee ligament is completely torn.
- A sprained joint will take several days or months to heal, depending on the severity.
- ACL - a connective tissue that helps stabilize the knee every time the muscles contract.
- STRAIN
- FRACTURE
- DISLOCATION
